I have a form on which I am using jquery.validate. I initially call validate with a set of rules and custom messages...
$("#formName").validate( {
rules: {
myExistingInput: {
required: true
}
},
messages: {
myExistingInput: {
required: "Enter something"
}
},
ignore: null, // include hidden fields (see below)
submitHandler: function(form) {
// do stuff
},
invalidHandler: function(event, validator) {
// do stuff (some of the fields may have been hidden by a collapsible panel
// if there is an error on one of those fields, expand the panel so the error
// becomes visible)
}
});
Later, I dynamically add fields to the form, and add rules for those fields too...
$("#formName").append(...);
$("#newInputName").rules("add", {
required: true,
messages: {
required: "Enter something else"
}
});
If I then submit the form, I get an error from within jquery.validate...
Exception occured when checking element newInputName, check the
'messages' method.TypeError: Unable to get property 'call' of
undefined or null reference
Debugging in the browser, I can see the error is being thrown from within the "check" function, and that the "method" variable is set to "messages".
If I remove the messages from the call to rules("add",...
$("#newInputName").rules("add", {
required: true
});
it works as expected, but obviously I now have no custom error messages.
I have seen many examples here on SO indicating that my syntax is correct. Any suggestions?
BTW: jQuery Validation Plugin - v1.11.0 - 2/4/2013
Your code seems to be working, without error, as you posted it.
DEMO with DOM ready: http://jsfiddle.net/UZTnE/
DEMO with PageInit & jQuery Mobile: http://jsfiddle.net/xJ3E2/
$(document).on("pageinit", function () {
$('#myform').validate({ // initialize the plugin
rules: {
field1: {
required: true
}
},
messages: {
field1: {
required: "Enter something"
}
}
});
$('[name*="field"]').each(function () {
$(this).rules('add', {
required: true,
messages: {
required: "Enter something else"
}
});
});
});
HTML:
<form id="myform">
<input type="text" name="field1" />
<input type="text" name="field2" />
<input type="submit" />
</form>
BTW:
this...
ignore: null, // include hidden fields
should be...
ignore: [], // include hidden fields
See: jQuery Validate - Enable validation for hidden fields
$(document).ready(function(){
$("#controlId").rules("add", {
required : true,
messages : { required : 'field is required.' }
});
});
as an answer to this old issue, I do like this to get the meassges inside the rules object.
After you have added the rules you can add messages like this:
var inputRules = $('input').rules();
inputRules.messages = {required: 'your message'};
Good luck!

Simple validator works, but once i get to add a little more things like above, things starts to act strange.
$(document).ready(function($) {
$('#testform').validate({
rules: {
testinput: {
required: true,
textonly: true,
messages: {
required: 'Input is required'
}
}
}
});
$.validator.addMethod(
"textonly",
function(value, element) {
var valid = false;
var check = /[^-'\.a-zA-Z0-9\s\u00C0-\u00D6\u00D8-\u00F6\u00F8-\u02AE]/.test(value);
if (check == false)
valid = true;
return this.optional(element) || valid;
},
"Please only enter letters, digits, spaces, periods, or hyphens."
);
});

Safari Returns error
[Error] TypeError: undefined is not an object (evaluating 'a.validator.methods[d].call'). Exception occurred when checking element testinput, check the 'messages' method.
Firefox says

The new method "textonly" works, and it displays the error message gracefully. However, when the input field is re-validated( you re-input text without illegal characters), the error occurs.
I've tried adding "textonly" custom message under textinput rules but it still errors.
How do i fix this?
The messages object is a sibling of rules... it does not belong inside of rules as you've done.
$('#testform').validate({
rules: {
testinput: {
required: true,
textonly: true,
}
},
messages: { // sibling of 'rules' object
testinput: {
required: 'Input is required',
textonly: 'letters only' // over-ride '.addMethod()' message
}
}
});

Please refer to documentation for messages to see proper usage.
I have two forms: one for adding a new user and the other for user data modification.
Forms are basically the same, only difference is that when doing modification username field should not be checked if exists in database.
In Js file I do field validations. One of those validations is checking if username already exists in database. In modification this should not be considered.
This is why I thought this, but it's not working:
I differentiate the two forms with div id.
(view snippet add_user form):
<div id="add_user">
<form action="{site_url()}admin/updateFrontUser" id="form_sample_2" class="form-horizontal" method="post">
(view snippet edit_user form):
<div id="edit_user">
<form action="{site_url()}admin/updateFrontUser" id="form_sample_2" class="form-horizontal" method="post">
and then:
(js file snippet)
var algo = $('.add_user', form2);
form2.validate({
errorElement: 'span', //default input error message container
errorClass: 'help-inline', // default input error message class
focusInvalid: false, // do not focus the last invalid input
ignore: "",
rules: {
username: {
required: true,
minlength: 2,
maxlength: 15,
pattern: "[A-z](([\._\-][A-z0-9])|[A-z0-9])*[a-z0-9_]*",
remote: {
data: function(){
if (algo) {
url: '/admin/checkUsername';
type: 'POST';
};
}
}
},
The remote rule it's supposed to check if username exists. That function is already built in my admin.php. It worked previously, before I made the modifications I mentioned.
So to resume, How do I do just to use remote rule only for a new user (I mean, when using add form) ?
Please Try below rule
$().ready(function() {
$("#id_frm").validate({
rules: {
"id_question": {
required: true
},
"id_number": {
required: function(){ return $('input:radio[name=id_question]:checked').val() == 'Yes' },
minlength: 10,
minlength: 10
},
"contact_method": {
required: function(){ return $('input:radio[name=id_question]:checked').val() == 'No' }
}
},
messages: {
"id_question": {
required: "Please choose if you have an ID or not."
},
"id_number": {
required: "Please Enter ID."
},
"contact_method": {
required: "Please choose a contact method."
}
},
});
});
I am having a really strange problem with Jquery validate that only occurs in Chrome. The validation on this page seems to be firing both the Highlight and the Unhighlight functions in the .validate() function so if I dont fill out the form it cycles through each element and applies the "invalid" class in the highlight function but then for some reason it goes through and immediately applies the code in unhighlight and I cant work out why?
JS
$(document).ready(function () {
//Validation for form fields on Payment form
/*This adds a method to test whether value is equal to placeholder, and if it is, don't consider it filled out. This is necessary to circumvent IE placeholder plugin*/
jQuery.validator.addMethod("notEqual", function (value, element, param) {
return this.optional(element) || value != param;
}, "Required.");
$('#payment-form').validate({
onfocusout: function (element) {
$(element).valid();
},
rules: {
"data[Payment][card_holder]": { required: true, minlength: 2 },
"data[Payment][card_number]": { required: true, creditcard: true },
"data[User][first_name]": { required: true, notEqual: "First Name" },
"data[User][last_name]": { required: true, notEqual: "Last Name" },
"data[UserDetail][company]": { required: true },
"data[UserDetail][job_title]": { required: true },
"data[UserDetail][telephone]": { required: true },
"data[User][email]": {
required: true,
email: true,
remote: {
url: "/usermgmt/users/email_exists",

}
},

credit_exp_month: { required: true, notEqual: "MM", number: true, max: 12, minlength: 2, maxlength: 2 },
credit_exp_year: { required: true, notEqual: "YYYY", number: true, minlength: 2, maxlength: 4 },
"data[Payment][cvv]": { required: true, number: true, minlength: 3, maxlength: 4 },
},
errorClass: 'error',
unhighlight: function (element, errorClass, validClass) {
$(element).removeClass(errorClass).addClass(validClass);
validateIcon(element);
},
highlight: function (element, errorClass, validClass) {
$(element).addClass(errorClass).removeClass(validClass);
validateIcon(element);
}
});
function validateIcon(element) {
$(element).siblings('span.validate_icon').remove();
if ($(element).hasClass('error')) {
alert("error");
$(element).closest('li').find('label>span:first').html('<span class="validate_icon invalid"> <span class="icon-stack"><i class="icon-sign-blank icon-stack-base"></i><i class="icon-exclamation"></i></span></span>');
} else if ($(element).hasClass('valid')) {
alert("valid");
$(element).closest('li').find('label>span:first').html('<span class="validate_icon valid"> <span class="icon-stack"><i class="icon-sign-blank icon-stack-base"></i><i class="icon-ok"></i></span></span>');
}
}
});
PHP Code that handles the email exists:
public function email_exists() {
$this->autoRender = false;
if($this->request->is('post')) {
$this->RequestHandler->respondAs('json');
if(!$this->User->findByEmail($this->request->data['User']['email'])) {
echo json_encode(true);
} else {
echo json_encode(false);
}
}
}
I have also tried simply echo "true"; and echo 1; I have tried everything suggested in the comments below but regardless - the problem exists.
I had the exact same problem, and by seeing your code I might say that you have the same cause, but let's break it down.
Checking
First, let's check that my comment is relevant, and I can actually help you. Comment the remote param on your email validation set up:
"data[User][email]": {
required: true,
email: true
},
Is your problem fixed? Great, keep reading (feel free to skip to the fix section).
The problem
1. When the plugin validates, it creates a list of errors, stored into an array called "errorList".
2. Have you ever used the showErrors functionality? It's there to show all the errors, but also to target-show errors. If you want to show specific errors, or to show errors that are out of the limits of the plugin (ej.: a 60s timeout has expired), you can use that method.
3. When showing specific errors, what that method does is to add the specified error(s) to the errorList.
4. The problem is that before adding new errors that list is cleared up (I didn't write the code, but it seems that it's done in order to keep that list nice and clean, and not having two different errors of the same input).
5. Now, when the email is checked remotely we are in the same situation of a timeout. So it uses the showErrors functionality, and that means that the form is validated when click, and some seconds later (with the PHP response), the email error is shown, but clearing up the errorList. That's what is happening.
The fix
If you are not going to do explicit use of showErrors, truth is that you can comment the line where the errorList is cleared up:
showErrors: function( errors ) {
if ( errors ) {
// add items to error list and map
$.extend( this.errorMap, errors );
//this.errorList = [];
for ( var name in errors ) {
...
If you are going to do an explicit use of that method, you can try this version instead. Doesn't clear the error list, but checks that you're not adding the same error twice:
showErrors: function( errors ) {
if ( errors ) {
// add items to error list and map
$.extend( this.errorMap, errors );
for ( var name in errors ) {
var tempElem = this.findByName(name)[0];
this.errorList = jQuery.grep(this.errorList, function( error, i ) {
return error.element != tempElem;
});
this.errorList.push({
message: errors[name],
element: tempElem
});
}
Let me know if worked or you have any problem.
This code of yours can be a problem...
onfocusout: function (element) {
$(element).valid();
},
You cannot put the .valid() method inside of the .validate() method without causing some serious issues.
This is the default onfocusout function from the plugin...
onfocusout: function( element, event ) {
if ( !this.checkable(element) && (element.name in this.submitted || !this.optional(element)) ) {
this.element(element);
}
}
What's the purpose of your custom onfocusout function? Generally, it's not needed since the onfocusout trigger is already built into the functionality. One constructs their own onfocusout function only to over-ride the built-in default. So if you want the default onfocusout behavior, just remove the onfocusout option entirely.
If you really want to emulate something like in your code, it would need to look like this...
onfocusout: function(element, event) {
this.element(element);
}
Quote OP Comment:
"as I said im not really sure what good it would do you: (I cant get it to format here..)"
$this->RequestHandler->respondAs('json');
if(!$this->User->findByEmail($this->request->data['User']['email'])) {
return json_encode(true);
} else {
return json_encode(false);
}
It does a lot of good to show any code that could be affecting the problem, especially any code that's wrong. This could have been solved two days ago.
return is for returning to the PHP function that called this one. In other words, return will do nothing here since there is no PHP function to return to. On the other hand, echo will output from PHP... and that's what you need for jQuery Validate remote...
if (....) {
echo true;
} else {
echo false;
}
PHP return versus PHP echo

I know this question has been asked before and I have read all the previous questions and I still can't get the jQuery validator to properly validate CKEditor fields.
My form is below:
<form id="faq-form">
<p>
<label>Title:</label>
<input type="text" id="faq-title" name="faq-title" class="faq-title" />
</p>
<p>
<label for="question">Question:</label>
<textarea name="question" id="question"></textarea>
</p>
<p>
<label for="answer">Answer:</label>
<textarea name="answer" id="answer"></textarea>
</p>
<p>
<input id="submit-faq" name="submit-faq" type="submit" value="Submit" />
</p>
</form>
Both textareas are converted to CKEditor fields using:
<script>
CKEDITOR.replace('question', { toolbar : 'forum' });
CKEDITOR.replace('answer', { toolbar : 'forum' });
</script>
When I try to validate, only the title field gets validated. I am not sure what I am doing wrong. Here is my javascript code for validating (the following sits in a jQuery document ready function).
$('#faq-form').submit(function() {
// Update textareas with ckeditor content
for (var i in CKEDITOR.instances) {
CKEDITOR.instances[i].updateElement();
$.trim($('#' + i).val());
}
// Validate the form
if ( ! $('#faq-form').validate({
rules: {
'faq-title': {
required: true,
minlength: 5
},
answer: {
required: true,
minlength: 20
},
question: {
required: true,
minlength: 20
}
}
}).form()) {
console.log('Form errors');
return false;
}
Once the validation is complete, I will use a $.post method instead of a normal form get or post so I can update my page without reloading. The $.post comes after the validation method but I didn't think it was necessary to show.
I was finally able to get it working. CKEditor hides the textareas when it runs and the jQuery validator ignores hidden elements. In the validate function, this can be changed. So my new code is below:
if ( ! $('#faq-form').validate({
ignore: "input:hidden:not(input:hidden.required)",
rules: {
'faq-title': {
required: true,
minlength: 5
},
answer: {
required: true,
minlength: 20
},
question: {
required: true,
minlength: 20
}
},
messages: {
'faq-title': {
required: "The title field is required"
},
answer: {
required: "The answer field is required"
},
question: {
required: "The question field is required."
}
},
errorElement: "span",
errorPlacement: function (error, element) {
error.appendTo(element.prev());
}
}).form()) {
console.log('Form errors');
return false;
}
I also added messages and modified the element and location of the errors when they are displayed. I figured that might be helpful to anyone else who stumbles across this.
Ok lets cut it down, I have spent hours to get the error message of CKEditor in the right place, because every time it showing up on top of the CKEditor or just after the label which is not look nice.
As CKEditor hides the textarea and put its span tag right after the textarea. Please use browser tool to inspect the dom elements, then you can see the textarea is hidden.
I just adjusted the code to get the error message label/span just under the CKEditor.
$('#messageForm').validate(
{
ignore: 'input:hidden:not(input:hidden.required)',
rules: {
msgTitle: {
minlength: 2,
required: true
},
msgText: {
minlength: 2,
required: true
}
},
errorElement: "span", // can be 'label'
errorPlacement: function (error, element) {
if ($(element).attr('id') == 'msgText') {
$('#cke_msgText').after(error);
} else {
element.after(error);
}
},
highlight: function (element) {
$(element).closest('.form-group').removeClass('text-success').addClass('error');
},
success: function (element) {
element
.closest('.form-group').removeClass('error').addClass('text-success');
}
});
Here, 'msgText' is the id of the textarea which is hidden, and cke_msgText id of the ckeditor, you can find the id by inspecting the dom element, perhaps ckeditor takes the id attribute of textarea and prefix 'cke_' with it.
My guess is that CKEditor doesn't play nicely with validation, at least by default. You'd need to remove the editors before validation (CKEditor works by hiding the thing being edited and then inserting an iframe and sticking the editable content in there; when you remove the editor it shuts down the iframe and copies over the content -- at least that's from memory). My guess is that if you inspect the DOM you'll see that the content of the textareas isn't changing.
You may find NicEdit more useful in this context -- see this thread:
https://stackoverflow.com/questions/3914510/wysiwyg-editor-without-iframe
Your code:
$('#faq-form').submit(function() {
// Update textareas with ckeditor content
for (var i in CKEDITOR.instances) {
CKEDITOR.instances[i].updateElement();
$.trim($('#' + i).val());
}
if ( ! $('#faq-form').validate({
rules: {
'faq-title': {
required: true,
minlength: 5
},
answer: {
required: true,
minlength: 20
},
question: {
required: true,
minlength: 20
}
}
}).form()) {
console.log('Form errors');
return false;
}
....
You should not use .validate() inside a conditional. That's what the .valid() method is for. .validate() is only used for initializing the plugin once on DOM ready with your rules & options. Once initialized, then .valid() can be used inside conditionals to trigger a test and return a boolean.
Also, you should not have .validate() inside of submit handler. The plugin has it's own submitHandler callback function.
Your code should be changed into something like:
$(document).ready(function() {
$('#faq-form').validate({ // initialize the plugin
// rules & options,
rules: {
'faq-title': {
required: true,
minlength: 5
},
answer: {
required: true,
minlength: 20
},
question: {
required: true,
minlength: 20
}
},
submitHandler: function (form) {
// Update textareas with ckeditor content
for (var i in CKEDITOR.instances) {
CKEDITOR.instances[i].updateElement();
$.trim($('#' + i).val());
}
}
})
if ( ! $('#faq-form').valid() ) { // test the form for validity
console.log('Form errors');
return false;
}
});
Best solution I found so far, simple and elegant:
$('#form1').validate({
ignore: [],
rules: {
corpo : {
required: function()
{
CKEDITOR.instances.corpo.updateElement();
}
}
}
})

http://christierney.com/2012/12/14/ckeditor-4-required-field-validation/
I am trying to make the Validation plugin work. It works fine for individual fields, but when I try to include the demo code for the error container that contains all of the errors, I have an issue. The problem is that it shows the container with all errors when I am in all fields, but I would like to display the error container only when the user presses the submit button (but still show inline errors beside the control when losing focus).
The problem is the message in the container. When I took off the code as mentioned in the answer below for the container, the container output just displays the number of errors in plain text.
What is the trick to get a list of detailed error messages? What I would like is to display "ERROR" next to the control in error when the user presses the tab button, and to have a summary of everything at the end when he presses submit. Is that possible?
Code with all input from here:
$().ready(function() {
var container = $('div.containererreurtotal');
// validate signup form on keyup and submit
$("#frmEnregistrer").bind("invalid-form.validate", function(e, validator) {
var err = validator.numberOfInvalids();
if (err) {
container.html("THERE ARE "+ err + " ERRORS IN THE FORM")
container.show();
} else {
container.hide();
}
}).validate({
rules: {
nickname_in: {
required: true,
minLength: 4
},
prenom_in: {
required: true,
minLength: 4
},
nom_in: {
required: true,
minLength: 4
},
password_in: {
required: true,
minLength: 4
},
courriel_in: {
required: true,
email: true
},
userdigit: {
required: true
}
},
messages: {
nickname_in: "ERROR",
prenom_in: "ERROR",
nom_in: "ERROR",
password_in: "ERROR",
courriel_in: "ERROR",
userdigit: "ERROR"
}
,errorPlacement: function(error, element){
container.append(error.clone());
error.insertAfter(element);
}
});
});
First your container should be using an ID instead of a class.. (I'm going to assume that ID is 'containererreurtotal')
Then Try this..
$().ready(function() {
$('div#containererreurtotal').hide();
// validate signup form on keyup and submit
$("#frmEnregistrer").validate({
errorLabelContainer: "#containererreurtotal",
wrapper: "p",
errorClass: "error",
rules: {
nickname_in: { required: true, minLength: 4 },
prenom_in: { required: true, minLength: 4 },
nom_in: { required: true, minLength: 4 },
password_in: { required: true, minLength: 4 },
courriel_in: { required: true, email: true },
userdigit: { required: true }
},
messages: {
nickname_in: { required: "Nickname required!", minLength: "Nickname too short!" },
prenom_in: { required: "Prenom required!", minLength: "Prenom too short!" },
nom_in: { required: "Nom required!", minLength: "Nom too short!" },
password_in: { required: "Password required!", minLength: "Password too short!" },
courriel_in: { required: "Courriel required!", email: "Courriel must be an Email" },
userdigit: { required: "UserDigit required!" }
},
invalidHandler: function(form, validator) {
$("#containererreurtotal").show();
},
unhighlight: function(element, errorClass) {
if (this.numberOfInvalids() == 0) {
$("#containererreurtotal").hide();
}
$(element).removeClass(errorClass);
}
});
});
I am assuming here that you want a <p> tag around each of the individual errors. Typically I use a <ul> container for the actual container (instead of the div you used called 'containererreurtotal') and a <li> for each error (this element is specified in the "wrapper" line)
If you specify #containererreurtotal as display: none; in your CSS, then you dont need the first line in the ready function ( $('div#containererreurtotal').hide(); )
You will find the documentation for the meta option in http://docs.jquery.com/Plugins/Validation/validate#toptions
If you want to display the errors beside the inputs AND in a separate error container you will need to override the errorPlacement callback.
From your example:
...
courriel_in: "ERROR",
userdigit: "ERROR"
}
,errorContainer: container
,errorPlacement: function(error, element){
var errorClone = error.clone();
container.append(errorClone);
error.insertAfter(element)
}
// We don't need this options
//,errorLabelContainer: $("ol", container)
//,wrapper: 'li'
//,meta: "validate"
});
...
The error parameter is a jQuery object containing a <label> tag. The element parameter is the input that has failed validation.
Update to comments
With the above code the error container will not clear errors because it contains a cloned copy. It's easy to solve this if jQuery gives a "hide" event, but it doesn't exist. Let's add a hide event!
First we need the AOP plugin
We add an advice for the hide method:
jQuery.aop.before({target: jQuery.fn, method: "hide"},
function(){
this.trigger("hide");
});
We bind the hide event to hide the cloned error:
...
,errorPlacement: function(error, element){
var errorClone = error.clone();
container.append(errorClone);
error.insertAfter(element).bind("hide", function(){
errorClone.hide();
});
}

Give it a try
I would remove the errorContainer and then intercept the validation on postback and in there add a container-error manually like this:
$("#frmEnregistrer").bind("invalid-form.validate", function(e, validator) {
var err = validator.numberOfInvalids();
if (err) {
container.html("THERE ARE "+ err + " ERRORS IN THE FORM")
container.show();
} else {
container.hide();
}
}).validate({ ... })
I have a slightly different solution:
jQuery(document).ready(function() {
var submitted = false;
var validator = jQuery("#emailForm").validate({
showErrors: function(errorMap, errorList) {
if (submitted) {
var summary = "";
jQuery.each(errorList, function() {
summary += "<li><label for='"+ this.element.name;
summery += "' class='formError'>" + this.message + "</label></li>"; });
jQuery("#errorMessageHeader").show();
jQuery("#errorMessageHeader").children().after().html(summary);
submitted = false;
}
this.defaultShowErrors();
},
invalidHandler: function(form, validator) { submitted = true; },
onfocusout: function(element) { this.element(element); },
errorClass: "formError",
rules: {
//some validation rules
},
messages: {
//error messages to be displayed
}
});
});
I solved this problem with the following short code:
errorElement: "td",
errorPlacement: function (error, element) {
error.insertAfter(element.parent());
}
My structure is the following:
<table>
<tr>
<td>Name:</td>
<td><input type="text" name="name"></td>
</tr>
</table>
So my errors will now shown directly in a <td> behind my <input>
I don't know if the validation plugin provides an option for this, but you can probably use standard jQuery to achieve what you want. Make sure you're container is initially hidden, by setting the display style to none:
<div id="container" style="display:none;"></div>
Then you can hookup an onsubmit event to the form which will make the container visible as soon as an attempt is made to submit the form:
jQuery('#formId').onsubmit(function() {
// This will be called before the form is submitted
jQuery('#container').show();
});
Hopefully combining that with your existing code should do the trick.
