Passing data to a bootstrap modal from Laravel

Question

Wonder if someone can help me with this one. I am a complete newbie with JS and JQuery.

I want to avoid accidents with deleting posts in my blog, so I want to have it so that when I hit delete it will pop up a modal to confirm I do want to delete the post and then do it or not.

I have added the following code.

 <!-- Button trigger modal to delete post -->
<button type="button" class="btn btn-default btn-xs" data-toggle="modal" data-target="#deletePost">
  Delete
</button>

<!-- Modal -->
<div class="modal fade" id="deletePost" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Delete Blog Post</h4>
      </div>
      <div class="modal-body">
        <p>You are about to delete a blog post, are you sure all that effort is to be sent to the unrecoverable trash can?</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default pull-left" data-dismiss="modal">OMG, NO!!!</button>
        <form action="/blog/{{ $post->id }}" method="POST">
            {{ csrf_field() }}
            {{ method_field('DELETE') }}
            <button type="submit" class="pull-right btn btn-danger">Delete it!</button>
        </form>
      </div>
    </div>
  </div>
</div>

Now all that works fine, all I now want to do is that when I click the "delete it!" button it will do just that.

It all works apart from deleting the right post, I want to pass

{{ $post->id }}

to the modal so that it will send the post id to the controller.

My question is how I pass the id above to the modal? I have read a lot of examples and they are all so different so thought it better to get some views.

Thanks!

I would very much recommend using SweetAlert plugin, it is visually compatible with Twitter Bootstrap and much more pleasant to use. This is a piece of code for multilingual, model-independant delete function:

    $('body').on('click', 'sweet-delete', function (e) {
        e.preventDefault();
        var id = $(this).data('id');
        var model = $(this).data('model');
        swal({
            title: lang.confirm_please,
            text: lang.delete_warning,
            type: "warning",
            showCancelButton: true,
            confirmButtonColor: "#DD6B55",
            confirmButtonText: lang.delete_button,
            closeOnConfirm: false,
            showLoaderOnConfirm: true,

        }, function(){
            $.post('/'+model+'/'+id, {_method: 'DELETE'}, function(data){
                swal({
                    title: lang.delete_title,
                    text: lang.delete_success,
                    type: "success",
                    timer: 5000
                }, function(){
                    window.location.href = '/'+model;
                });
            });
        });
    })

And in you view:

<button data-id="{{$post->id}}" data-model="blog" class="pull-right btn btn-danger sweet-delete">@lang('app.delete')</button>

I have to mention that in order to attach CSRF token to my ajax forms I use:

$.ajaxSetup({
        headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')}
    });

in my app.js, and

<meta name="csrf-token" content="{{csrf_token()}}">

in my main layout file.
