PATCH ajax request not receiving any data from using multipart form data

I use jquery, and just a suggestion, try a put request, it's worked for me.

@jlrdw Still the same....

An answer I gave a while back

jquery

<script>
    $(function () {
        $("#postjq").click(function (event)
        {
            event.preventDefault();
            var $post = {};
            $post.petid = $('#petid').val();
            $post.species = $('#species').val();
            $post.ocheck = ($("#ocheck").prop("checked") == true ? '1' : '0');
            $post._token = document.getElementsByName("_token")[0].value
            $post._method = document.getElementsByName("_method")[0].value
            alert('here');
            $.ajax({
                url: 'http://localhost/laravel60/pet/petupdate',
                type: 'PUT',
                data: $post,
                cache: false,
                success: function (data) {
                    alert('Your data updated');
                    return data;
                },
                error: function () {
                    alert('error handing here');
                }
            });
        });
    });
</script>

route

Route::put('pet/petupdate', 'PetController@petUpdate');

I have these two lines also in form

<?php echo csrf_field(); ?>
<input type="hidden" name="_method" value="PUT">

controller

    public function petUpdate(Request $request)
    {

        $petid = $request->input('petid');
        $species = $request->input('species');
        //$ocheck = $request->input('ocheck');
        /* $postdata = [
          'species' => $species,
          'ocheck' => $ocheck
          ]; */
        $postdata = [
            'species' => $species
        ];
        //dd($postdata);
        DB::table('dc_pets')
                ->where('petid', $petid)
                ->update($postdata);
        
    }

Was done quick, no auth or validation, but add that.

And you can redirect from the jquery.

Your headers should work. Make sure you clear or delete temp views and clear browser cache between code changes.

Also add this Header to your headers

'Content-Type': 'application/json'

Like This

headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content'), 'Content-Type': 'application/json' }

@jlrdw I have no problem by using form.serialize() method or your method. The problem occurs when i try to use data: new FormData($(form)[0]), because i need to upload image too.

@mohansharma I have tried your method, i still got empty array but it posted as a PATCH request.

If you are using FormData then there is no need to include application/json header and you already specified @csrf in your form therefore FormData will also send that token so no need for X-CSRF-TOKEN header as well

And you need to send the request as POST and your laravel application will automatically get it as PATCH request because you included @method('PATCH') so your patch route and method for that route will get triggered

You could verify the method type in you controller method using this

$request->method()

@mohansharma Ahhh i seee, no wonder why i set it to POST it will works. So if using FormData must set it as POST request?
