Laravel 5.1 Ajax调用'Like'系统没有发生

I am building an application where users can upload projects. I am implementing a system where users can 'Like/Unlike' other projects. I am trying to use an AJAX call to save likes. Users are able to like projects on the detail page of a project (/projects/{id})

I have a table users, projects and likes. My plan is to save the likes in the likes table obviously so a record looks like this: id, user_id, project_id. In the future I can do a COUNT query and find out how many likes each project has, etc.

Currently nothing happens when I click on the like button I get no errors, nothing happens.

My files: Routes.php

Route::get('/', 'LikeController@index');
Route::post('projects/{id}', 'LikeController@like');

LikeController.php:

public function like()
{
    if(Request::ajax()) {
        $data = Input::all();
        print_r($data);die;
    }
}

My view: show.blade.php

{!! Form::open(array('url'=>'projects/'.$project->id.'/like','method'=>'POST', 'id'=>'myform')) !!}
{!! Form::button('Like', array('class'=>'send-btn')) !!}
{!! Form::close() !!}

My AJAX call

<script type="text/javascript">
    $(document).ready(function(){
        $('.send-btn').click(function(){
            $.ajax({
                url: 'projects',
                type: "post",
                data: {'user_id': $('input[name=user_id]').val(), 'project_id': $('input[name=project_id]').val()},
                success: function(data){
                    alert(data);
                }
            });
        });
    });
</script>

In your ajax function you have an option url: 'projects'. This means your ajax call will be sent to the relative projects path. To fix this, change it to url: '/projects'.

Also your route includes an id of the project projects/{id}, so you have to add it to your ajax call option too.

$('.send-btn').click(function(){
    $.ajax({
        url: $(this).parent().attr('action'),
        type: "post",
        data: {'user_id': $('input[name=user_id]').val(), 'project_id': $('input[name=project_id]').val()},
        success: function(data){
            alert(data);
        }
    });
});

as per your form action you need to change route,

Like this.

Route::post('projects/{id}/like', 'LikeController@like');

Instead of this one

Route::post('projects/{id}', 'LikeController@like');

If you want to send an AJAX request, when you submit the form you should prevent the default event and then make a request, like so:

$('#form-id').on('submit', function(e) {
    e.preventDefault(); //stops the form from being submited the normal way.

    $.ajax({
        url: 'projects',
        type: "post",
        data: {'user_id': $('input[name=user_id]').val(), 'project_id': $('input[name=project_id]').val()}
    })
    .done(function(response) { 
        //handle response on success
    })
    .fail(function(xhr) {
        //handle failed request
    });
});

You will also need to change the url to the correct path, the way it is set in your routes.php file.
