It would be helpful if you show your form code. Also make sure you have a csrf token on form, see the docs.

I'm using hurl.it to generate post request. I'm just setting request type to post and specify URL. Is there a something else that needs to be added?

I am having the same problem all of a sudden, but only with one form on a site where there are many many forms and routes. In my HTML I have:

    <main class="container">
        <form class="form-horizontal" action="/pallet/save" method="post" accept-charset="utf-8" role="form">
            <div class="row">
                 <div class="col-xs-12">
                      <div class="pm-well">	
                           <h2>Scan Add Pallet</h2>
                               <div class="form-group">
                                     <label class="col-xs-12 col-sm-2" for="location">Location: </label>
                                    <div class="col-xs-12 col-sm-8">
                                        <input type="text" class="form-control" name="location" id="location">
                                     </div>
                               </div>
                             </div>
                         </div>
                   </div>
                  <div class="row">
                      <div class="col-xs-12">
                            <input type="submit" class="pm-btn pm-btn-confirmation medium-btn" value="Add Pallet">
                      </div>
                 </div>
            </form>
    </main>

And in my routes file I have:

The error I get is:
~~~ Call to undefined method Illuminate\Http\Request::post() ~~~ 

I've tried changing the Route to Route::any but get the same error.

This is the only form submission that is throwing that error; all the other forms work as expected so I'm kinda stumped here as to what the problem is.

As a control test, I copied my html form and setup a straight html and php (not using Laravel or any other PHP framework) webroot with a separate virtual host domain and changed the form action to point to another php script where I can echo out the post data and server request methods via PHP's super globals ($_SERVER['REQUEST_METHOD'] & $_POST).

Everything works as expected this way. Is there a chance that some bug has been introduced? Like I said, I have several web sites built in Laravel 4 each of which has many routes and form submissions and have never encountered this before.
