[resolved] cakephp 3 - unable to post form data to controller function

cakephp3- unable to post form data to the controller function

I think your form is submitting but not through the post method. So I would like to say you that, please make the bellow changes before submitting the form.

$pages ='';
    if ($this->request->is('post')) 
    {
        echo "Request is post";die;
        $pages =   $this->request->data('Contact');
    }else{
        echo "request is not post";die;
    }
    $this->set(compact('pages'));
    $this->set('_serialize', ['pages']);

Now check, which is printing in the display. Then I can help you further.

Remember: - fill the form, then after change the controller method, then press submit method.
