I'm a newbie to Laravel 4, and I'm trying to get a form validation in bootstrap modal.
My modal have a form with a text input and a submit button, and I want that when the validation fails, the modal show me the error.
But the modal, after the validation and the page refresh, is closed.
Here is the code from the controller and the view:
Controller code:
public function postAvatar()
{
$avatar_rules = array(
'avatar_src' => 'url',
);
$validator = Validator::make(Input::all(), $avatar_rules);
$validator->setAttributeNames(User::$names_attr);
if ($validator->passes())
{
$avatar_src = (Input::get('avatar_src'))? Input::get('avatar_src') : URL::asset('assets/images/user/default-user-avatar.png');
$user = User::find(Auth::id());
$user->avatar_src = $avatar_src;
if ($user){
return Redirect::to('dashboard')->withSuccess("Success: avatar updated.");
}
return Redirect::to('dashboard')->withError("Error: an error has occurred.");
}
return Redirect::back()->withErrors($validator);
}
View code:
<!-- Modal -->
<div class="modal fade" id="avatarModal" tabindex="-1" role="dialog" aria-labelledby="avatarModalLabel" aria-hidden="true">

{{ Form::open(array('url' => 'dashboard/avatar', 'method'=>'post', 'role'=>'form')) }}
<ul>
#foreach($errors->all() as $error)
<div class="alert alert-danger" role="alert">{{ $error }}</div>
#endforeach
</ul>

How can I resolve ?
Thanks.
SOLVED:
Controller code:
public function postAvatar()
{
$avatar_rules = array(
'avatar_src' => 'url',
);
$validator = Validator::make(Input::all(), $avatar_rules);
$validator->setAttributeNames(User::$names_attr);
if ($validator->passes())
{
$avatar_src = (Input::has('avatar_src'))? Input::get('avatar_src') : URL::asset('assets/images/user/default-user-avatar.png');
$user = User::find(Auth::id());
$user->avatar_src = $avatar_src;
if ($user->save()){
if(Request::ajax()){
return Response::json(array('success' => true));
}
}
return Redirect::to('dashboard')->withError("Error: an error has occurred.");
}
return Response::json(array('errors' => $validator->errors()->toArray()));
}
View code:

Ajax:
<script>
$(document).on('submit', '#avatar_form', function(event){
var info = $('.avatar_alert');
event.preventDefault();
var data = { avatar_src: $("#avatar_src").val() }
$.ajax({
url: "/dashboard/avatar",
type: "POST",
data: data,
}).done(function(response) {
info.hide().find('ul').empty();
if(response.errors)
{
$.each(response.errors, function(index, error){
info.find('ul').append(error);
});
info.slideDown();
}
else if(response.success){
window.location.href = "/dashboard";
}
});
});
</script>
Your best bet would be to validate the form via AJAX to avoid the page reloading entirely. You would then check the response of your AJAX request for the presence of errors and show them inside the modal if they exist.
You could also add in client side validation to prevent the request being made until the rules are satisfied. I wouldn't recommend using this INSTEAD of server side validation but using it ASWELL as is normally quite desirable.
To accomplish this, you'd need to do something along these lines:
Javascript:
Catch submit event of your form and make an AJAX request.
$(document).on('submit', 'form', function(event){
event.preventDefault();
var data = { avatar_src: $("#avatar_src").val(); };
$.ajax({
url: "/dashboard/avatar",
data: data
type: "POST",
}).done(function(response) {
if(response.errors)
{
// Add error to Modal Body
}
else
{
// Show success message, close modal?
}
});
});
Backend:
Modify your controller method to detect if the current request is an AJAX request and if so, return the response in JSON instead of Redirecting. For example:
if(Request::ajax())
{
return Response::json(array('errors' => $validator->messages()));
}
else
{
return Redirect::back()->withErrors($validator);
}
I've not tested any of that code so might contain some typos/errors but hopefully this helps you!
I was facing same issue. After research on internet,I found that Laravel don't support withSuccess('success_msg') method.
return Redirect::to('dashboard')->withSuccess("Success: avatar updated.");
Here is complete discussion on this topic:
https://github.com/laravel/framework/issues/906.
But you can handle this issue with this approach:-
- For Error message:-
[code has to be added in controller]
return Redirect::to('view')->withErrors('your error message.');
[code has to be added in view]
#if(isset($errors) && count($errors->all())>0)
<ul>
#foreach($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
#endif
- for succcess message:-
[code has to be added in controller]
$success_msg='your success message.';
Session::flash('successMsg', $success_msg);
return Redirect::to('view');
[code has to be added in view]
#if (Session::has('successMsg'))
{{ Session::get('successMsg') }}
#endif
This approach is working fine for me.
For better display of your errors you can use bootstrap css.

With the following code I'm trying to validate an entry field in JavaScript. The validation requires only 10 characters. When you authenticate, it is supposed to display a modal with a confirmation message:
function myFunction() {
var con_code, text;
//getting the field
con_code = document.getElementById("con_code").value;
if ($.trim($('con_code').val()).length == 0) {
text = "Authentication code is not valid";
}
//trigger to the modal if it meets the condition
$(document).ready(function() {
$("#con_code").click(function() {
$("#myModal").modal();
});
});
document.getElementById("error_con_code").innerHTML = text;
}
<div class="container">
<h2>Activate Modal with JavaScript</h2>
<!-- Trigger the modal with a button -->
<div class="form-group">
<label>Confirmation Code.</label>
<input type="text" name="con_code" id="con_code" class="form-control" required="required" placeholder="Enter your Confirmation Code" />
<br> //the error code display
<span id="error_con_code" class="text-danger"></span>
<br> //the authenticate button
<button type="button" class="btn btn-success btn-sm" id="con_code" onclick="myFunction()">Authenticate</button>
</div>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button> //the modal
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
However, it is not authenticating the confirm code. How can I fix it?
You have an error at:
if($.trim($('con_code').val()).length ==0){...}.
It should be $('#con_code')
Also you have 2 elements with the same id="con_code".
Please check with the following codes.
I am assuming you want to show the modal when there is 10 chars in the input field. If the rule changes, then please edit at: 'if ($.trim(con_code.val()).length != 10) {}' in the below codes.
$(document).ready(function() {
myFunction();
});
function myFunction() {
$("#con_code_btn").click(function() {
var con_code = $('#con_code');
var error_con_code = $('#error_con_code');
error_con_code.html('');// Remove Previous Error Message(if any);
if ($.trim(con_code.val()).length != 10) {
error_con_code.html("entication code is not valid");
}
else {
$("#myModal").modal();
}
});
}
Also please change the id of the button to "con_code_btn" in the form:
<button type="button" class="btn btn-success btn-sm" id="con_code_btn" onclick="myFunction()">Authenticate</button>

I have a strongly typed view in which I am looping over some objects from a database and dispaying them in a jumbobox with two buttons in it. When I click one of the buttons I have a modal popping up. I'd like to have somewhere in this modal the name and the id of the corresponding object, but I do not really know how to do this. I am a bit confused where to use c# and where javascript. I am a novice in this, obviously.
Can someone help?
This is the code I have so far. I don't have anything in relation to my question, except the code for the modal :
#model IEnumerable<eksp.Models.WorkRole>
#{
ViewBag.Title = "DisplayListOfRolesUser";
}
<div class="alert alert-warning alert-dismissable">You have exceeded the number of roles you can be focused on. You can 'de-focus' a role on this link.</div>

I think your confusing the server side rendering of Razor and the client side rendering of the Modal. The modal cannot access your Model properties as these are rendered server side before providing the page to the user. This is why in your code <h4 class="modal-title">#Html.DisplayFor(modelItem => item.RoleName)//doesn't work</h4> this does not work.
What you want to do is capture the event client side in the browser. Bootstrap allows you to achieve this by allowing you to hook into events of the Modal. What you want to do is hook into the "show" event and in that event capture the data you want from your page and supply that to the Modal. In the "show" event, you have access to the relatedTarget - which is the button that called the modal.
I would go one step further and make things easier by adding what data you need to the button itself as data-xxxx attributes or to DOM elements that can be easily access via JQuery. I have created a sample for you based on what you have shown to give you an idea of how it can be achieved.
Bootply Sample
And if needed... How to specify data attributes in razor
First of all
you will need to remove the data-toggle="modal" and data-target="#myModal" from the button, as we will call it manually from JS and add a class to reference this button later, your final button will be this:
<button type="button" class="btn btn-default btn-lg modal-opener">Had role in the past</button>
Then
In your jumbotron loop, we need to catch the values you want to show later on your modal, we don't want to show it, so we go with hidden inputs:
<input type="hidden" name="ID_OF_MODEL" value="#item.WorkRoleId" />
<input type="hidden" name="NAME_OF_MODEL" value="#item.RoleName" />
For each information you want to show, you create an input referencing the current loop values.
Now you finally show the modal
Your document.ready function will have this new function:
$('.modal-opener').on('click', function(){
var parent = $(this).closest('.jumbotron');
var name = parent.find('input[name="NAME_OF_MODEL"]').val();
var id = parent.find('input[name="ID_OF_MODEL"]').val();
var titleLocation = $('#myModal').find('.modal-title');
titleLocation.text(name);
// for each information you'll have to do like above...
$('#myModal').modal('show');
});
It simply grab those values we placed in hidden inputs.
Your final code
#model IEnumerable<eksp.Models.WorkRole>
#{
ViewBag.Title = "DisplayListOfRolesUser";
}
<div class="alert alert-warning alert-dismissable">You have exceeded the number of roles you can be focused on. You can 'de-focus' a role on this link.</div>

I need to load dynamic data into bootstrap modal box.
JS:
$(function() {
$('.push').click(function() {
var id = $(this).attr('id');
$.ajax({
type: 'post',
url: '../controller/booksdetails.php', // in here you should put your query
data: 'cmid=' + id, // here you pass your id via ajax .
// in php you should use $_POST['post_id'] to get this value
success: function(r) {
// now you can show output in your modal
$('#cm').modal({
backdrop: 'static',
keyboard: false
}) // put your modal id
$('.something').show().html(r);
}
});
});
});
PHP file :
if(isset($_POST['cmid'])){
$DB = mysqli::f("SELECT * FROM " . BOOKS . " WHERE id = ?",filter_var($_POST['cmid'], FILTER_VALIDATE_INT));
print_r($DB);
}
and print data into modalbox div with class="something". this method true worked and print all php array result.
now I need to work with php array aftar load data into modalbox(work with php class, secure data, ....). I mean is: load php data into modalbox (ie : json) not print result into modalbox.
how do can I generate this?

I use bootbox to display bootstrap-style modals in Meteor, using Meteor templates (so that the modals are reactive). If you
meteor add mizzao:bootboxjs
Then the following function will suffice to display a modal:
function displayModal(template, data, options) {
// minimum options to get message to show
options = options || { message: " " };
var dialog = bootbox.dialog(options);
// Take out the default body that bootbox rendered
dialog.find(".bootbox-body").remove();
// Insert a Meteor template
// Since bootbox/bootstrap uses jQuery, this should clean up itself upon removal
Blaze.renderWithData(template, data, dialog.find(".modal-body")[0]);
return dialog;
}
You'll find that the default bootbox modals are also useful for non-reactive messages.
