Issue
I have a form constructed using Bootstrap 3.
I post the data via Ajax to a PHP page "formhandle.php", which is used to handle all forms on the site.
However, the submit input information is not being sent.
HTML Form
<form role="form" id="frmLogin" action="dashboard/inc/formhandle.php">
<p class="text-danger frmLogin_error" style="display:none;">Invalid username/password combination</p>
<div class="form-group">
<label for="frmLogin_username">Username/domain</label>
<input id="frmLogin_username" name="username" type="text" class="form-control" placeholder="example.com">
</div>
<div class="form-group">
<label for="frmLogin_password">Password</label>
<input id="frmLogin_password" name="password" type="password" class="form-control" placeholder="Password">
</div>
<input type="submit" name="frmLogin_submit" value="Login" class="btn btn-default" />
</form>
jQuery/Ajax Submission
$('form').submit( function(e) {
var formName = $(this).attr('id');
$('#'+formName).find('.'+formName+'_error').hide();
$(this).find('input[type=submit]').prop('disabled',true);
var postData = $(this).serializeArray();
var formURL = $(this).attr("action");
$.ajax({
url : formURL,
type: "POST",
//async: false,
data : new FormData(this),
success:function(data, textStatus, jqXHR) {
console.log(data);
if(data=='success'){
console.log('success');
} else {
$('#'+formName).find('.'+formName+'_error').show();
}
$('#'+formName).find('input[type=submit]').prop('disabled',false);
},
error: function(jqXHR, textStatus, errorThrown) {
alert('Error: An unknown error occurred.');
},
cache: false,
contentType: false,
processData: false
});
e.preventDefault();
});
PHP Code
require_once('connect.php');
require_once('functions.php');
exit(print_r($_POST));
if(isset($_POST['frmLogin_submit'])){
$username = $_POST['username'];
$password = $_POST['password'];
$stmt = $dbh->prepare('SELECT * FROM `users`
WHERE (`username`=? AND `password`=?)
OR (`email`=? AND `password`=?');
if($stmt->execute(array($_POST['username'],$_POST['password'],$_POST['username'],$_POST['password']))){
if($stmt->rowCount()>1) exit('error: invalid data');
$userData = $stmt->fetch(PDO::FETCH_ASSOC);
validateUser($userData['id']);
exit('success');
}
}
Console Output
Array
(
[username] => username_input
[password] => password_input
)
1
What Console Output I Expect
Array
(
[username] => username_input
[password] => password_input
[frmLogin_submit] => Login
)

Why isn't the frmLogin_submit input value being posted?
Because you have disabled the input[type="submit"]
From your code:
$(this).find('input[type=submit]').prop('disabled',true);
Disabled inputs,textareas are not submitted with the form.
Suggestion:
Set readonly to the input, if you don't want the user to interact with the button.
$(this).find('input[type=submit]').prop('readonly',true);
it is like a billion years from the time this question was share but hope this helps someone.
i had same problem, and this is the solution i used:
$.ajax({
type: "POST",
url: url,
data: form.serialize()+"&submit="+document.activeElement.value,
don't know how risky this might be, but all things being equal, this seems to be a quick fix to the problem.
Edited:
Someone contacted me to complain that this code was not working.
After I reviewed his code, I saw that he had used a different name for the submit input which was not "submit", So I'm here to review my answer to make it more dynamic.
$.ajax({
type: "POST",
url: url,
data: form.serialize()+"&"+document.activeElement.name+"="+document.activeElement.value,

Can someone help a JS newbie?
Almost everything is working, results are returned, nothing opens new tabs, forms submit to MC database....however I cannot get the result html to post to the correct DIV. All results are being posted to the footer div.
I am guessing my selectors are not specific enough? But I do not have the knowledge on how to structure correctly.
2 forms on page using AJAX submit.
1 pop up form and 1 form in footer..... but all the result html is posting the the div in the footer.
I have adjusted the function register names as suggested (and updated the code below), but form result data is still going to the footer div
//JAVASCRIPT

//define argument as the current form especially if you have more than one

event.preventDefault();
// submit form via ajax
register($registerFooterFormbutton);
} catch(error){}

You have two functions with the same name "register" so when you press the submit button in either forms it runs in the register function in the footer since it has the same name as the one dedicated to the popup form
Use this code and your form will work as expected:
//JAVASCRIPT
// FOOTER FORM. waits for form to appear rather than appending straight to the form. Also helps if you have more than one type of form that you want to use this action on.
$(document).on('submit', '#footer-mc-embedded-subscribe-form', function(event) {
try {
//define argument as the current form especially if you have more than one
var $registerFooterFormbutton= jQuery(this);
// stop open of new tab
event.preventDefault();
// submit form via ajax
register1($registerFooterFormbutton);
} catch(error){}
});
// POP UP FORM. waits for form to appear rather than appending straight to the form. Also helps if you have more than one type of form that you want to use this action on.
$(document).on('submit', '#pop-mc-embedded-subscribe-form', function(event) {
try {
//define argument as the current form especially if you have more than one
var $registerPopUpFormbutton= jQuery(this);
// stop open of new tab
event.preventDefault();
// submit form via ajax
register($registerPopUpFormbutton);
} catch(error){}
});
// POP UP FORM. post result to div
function register($registerPopUpForm) {
$('#pop-mc-embedded-subscribe-form').val('Sending...');
$.ajax({
type: 'GET',
url: 'https://websitename.us16.list-manage.com/subscribe/post-json?u=.....&c=?',

$('#pop-mce-EMAIL').css('borderColor', '#ffffff')
$('#pop-subscribe-result').css('color', 'rgb(53, 114, 210)')

You are defining the register() function two times with the same name. The second one overwrites the first and everytime you call the function with that name you call the second function. An easy solution is to change the name of the functions (i.e registerPopUpForm() , registerFooterForm() ) and use them accordingly.
I have a form on my front-end and when the submit button is clicked I want to send the details to my get-emp.php file without page reload.
The code looks like this:
index.html
<form class="form-emp-details hide" action="">
<div class="form-group">
<label for="">First name:</label>
<input type="text" class="form-control input-emp-firstname" name="input_emp_firstname">
</div>
<div class="form-group">
<label for="">Last name:</label>
<input type="text" class="form-control input-emp-lastname" name="input_emp_lastname">
</div>
<div class="form-group">
<label></label>
<button type="submit" class="btn btn-default btn-submit-1" name="submit_emp_details">Save</button>
</div>
</form>
custom.js
$(".form-emp-details").("submit", function(e) {
var input_first_name = $(".input-emp-firstname").val();
$.ajax({
type: "POST",
url: "get-emp.php",
data: {
input_emp_firstname:input_first_name,
},
success: function(data) {
console.log(data)
},
error: function(xhr,status,error) {
console.log(error);
}
});
});
get-emp.php
if(isset($_POST['submit_emp_details'])) {
$firstname = $_POST['input_emp_firstname'];
echo $firstname;
}
I want to display the submitted form data on get-emp.php file but it seems that I am not able to detect the submitted button and echo the form data on.
My goal is to capture all form data with a single request variable or identifier $_POST['submit_emp_details']
Any help is greatly appreciated. Thanks
$("#MyformId").submit(function(e) {
e.preventDefault();
var form = $(this);
var url = form.attr('action');
$.ajax({
type: "POST",
url: url,
data: form.serialize(),
success: function(data)
{
// success..
}
});
});
You passing the POST data of firstname and lastname by:
input_emp_firstname
input_emp_lastname
so, you need to change the $_POST['submit_emp_details'] to $_POST['input_emp_firstname'] on file get-emp.php to
<?php
if(isset($_POST['input_emp_firstname'])) {
$firstname = $_POST['input_emp_firstname'];
echo $firstname;
}
Edit 2:
$.ajax({
type: "POST",
url: "get-emp.php",
cache: false,
data: {
submit_emp_details: {
input_emp_firstname:input_first_name,
input_emp_lastname:input_last_name
}
},
success: function(data) {
console.log(data)
},
error: function(xhr,status,error) {
console.log(error);
}
});
im trying to submit an ajax post in laravel but im having some problem regarding the form's csrf token. In my form, if the conditions i set in my ajax post url has been met the first time the form has been submitted. However if i submit the form and purposely failed the conditions i set in my ajax post url in the first try, If i submit the form again i get a token mismatch exception in my ajax error log. Do i need to refresh the csrf_token every ajax post?
Below is my code
JS
$(document).on('submit','.registration-form',function(e){
e.preventDefault();
var form = $(this);
var form_url = $(this).attr("action");
var form_values = $(this).serialize();
$.ajax({
url:form_url,
type:'POST',
data:form_values,
dataType: 'json',
async:false,
success: function(result){
console.log(result);
if(result['status']==true){
location.href = result['redirect'];
}
else{
form.find(".form-details").show().html(result['message']);
}
},
error: function(ts) {
console.log(ts.responseText)
}
});
});
HTML
<form action="{{ url('login') }}" method="POST" class="registration-form">
{{ csrf_field() }}
<input type="text" name="username" class="input" placeholder="Email">
<input type="password" name="password" class="input" placeholder="Password">
<button class="button is-redbox is-flat is-fullwidth">Login</button>
</form>
Are u sure that each time that is send in ajax?
data: {
"_token": "{{ csrf_token() }}",
}
$("#cform")[0].reset();
or in plain javascript:
document.getElementById("cform").reset();
public function regenerateToken(){
session()->regenerate();
return response()->json([
'msg'=>'success',
'token'=>csrf_token()
]);
}
$('#form').submit(funtion(event) {
event.preventDefault(event);
// Submit the form using AJAX.
$.ajax({
type: 'POST',
url: form.attr('action'),
data: formData
})
.done(function(response) {
// Make sure that the formMessages div has the 'success' class.
if (response.msg === 'success') {
$('#token').val(response.token);
console.log($('#token').val());
}
}
$('input[type="text"],input[type="email"] ,textarea, select').val(''); $(this).trigger('reset');
});
My form:
<form class="form-inline signup" action="php/signupForm.php" role="form" id="signupForm">
<div class="form-group">
<input type="email" name="email" class="form-control" placeholder="Email address">
</div>
<div class="form-group">
<button type="submit" class="btn btn-theme ladda-button" data-style="expand-left">
<span class="ladda-label" id="notice">Get notified!</span>
</button>
</div>
</form>
the end of my php script
$response = array(
"status" => $status,
"message" => $message
);
echo json_encode($response);
My page is receiving data like:
{"status":0,"message":"This email is already on list!"}
using JS I need to parse that data and then update text within an element.
<span id="notice">Get notified!</span>
here's my script which doesn't work, after senging form data to my php script I get a white screen that shows the json strong
$(document).ready(function() {
$.ajax({
dataType: 'json',
$('#notice').text(data.message);
});
});
You have to handle the response in a callback.
$(document).ready(function() {
$('form').on('submit', function(e) {
e.preventDefault();
$.ajax({
data: $(this).serialize(),
url: $(this).attr('action'), // Or the path of the PHP file
dataType: 'json',
}).done(function(response) {
$('#notice').text(response.message);
});
});
});
See the related docs here
That ajax call is not well formed, missing success callback and url e.g:
$(document).ready(function () {
$.ajax({
url: '/the/url/where/your/data/comes/from/',
dataType: 'json',
success: function (data) {
$('#notice').text(data.message);
}
});
});
Your code as is, is just executing at page load and not on submission of a form. You need to attach an onsubmit event, prevent the default action of doing the form submit and do your ajax call in there. Also your ajax call itself was malformed
$("#yourFormID").submit(function(e){
e.preventDefault();
$.ajax({
url:"/urlToServerScript",
data:{} //any form data the script needs you should be put here,
dataType:"json" //type of response the server will output
}).then(function(data){
$('#notice').text(data.message);
});
});
I have very very little knowledge of javascript but somehow I managed to post form data to a php file.
Now I am facing a little problem, there are some validations on php file, what I want is if there is any validation fails and the php file returns $error = 'Invalid data'; I want this ajax request to simply display the error message.
Or, if it returns no error, or $error = ''; this ajax request redirect to thankyou.php page.
HTML file:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$(document).ready(function (e){
$("#frmContact").on('submit',(function(e){
e.preventDefault();
$.ajax({
url: "data.php",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData:false,
success: function(data){
if (data == 'true') {
window.location.href="thankyou.php";
};
if (data !== 'true') {
$("#status").html(data);
};
},
error: function(){
}
});
}));
});
<form id="frmContact" action="" method="post">
<div id="status"></div>
<div>
<label>Email</label>
<span id="userEmail-info" class="info"></span><br/>
<input type="text" name="userEmail" id="userEmail" class="demoInputBox">
</div>
<div>
<input type="submit" value="Send" class="btnAction" />
</div>
</form>
data.php
<?php
// PHP code above...
//Lets add $error variable for test purpose...
$error = 'Invalid data';
?>
Change only success function like this
success: function(data){
if (data === 'Invalid data') {
$("#status").html(data);
}
else {
window.location.href="thankyou.php";
}
}
and in php you should echo $error
Echo out "Success" if everything goes according to what you wanted in the posted data i.e all validations passed or echo out any specific validation error. The echoed response will be the response according to which our JS will act accordingly.
$(document).ready(function (e){
$("#frmContact").on('submit',(function(e){
e.preventDefault();
$.ajax({
url: "data.php",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData:false
})
.done(function(response){
if(response=="Success")
window.location.href="thankyou.php";
else
$("#status").html(response);
});
}));
});
