how to send data using post ajax and get it from a symfony controller

Question

Hi im trying to dend data to my method in the controller using an ajax script :

$("#form_enr").submit(function(ev) {
    ev.preventDefault(); 

    var ev = $("#mySelect").val();
    var text =$("#form_Text").val();

    console.log(text);
    console.log(ev);

    $.ajax({
        type: "POST",
        url: "{{ path('invitation_enregistrerInv')}}",
        data : 'ev=' + ev + '&text=' + text,
        success: function(data){
            $('.portlet-body').html(data);        
        }
    });    

});

and to get it I use this syntax :

public function enregistrerInvAction()
{
    $inv = new Invitation();    
    $em = $this->getDoctrine()->getManager();
    $request = $this->get('request');

    $ev = $request->request->get('ev');
    $text = $request->request->get('text');
      
    $inv->setCreatedAt(new \Datetime());
    $inv->setUpdatedAt(new \Datetime());
    $inv->setText($text);
       
    $em->persist($inv);
    $evenement=$em->getRepository('EvEvenementBundle:Evenement')->findById($ev);
    $evenement=new Evenement();
    $evenement->setInvitation($inv);
    $em->persist($evenement);
    $em->flush();
    $this->addFlash(
        'success',
        'Les informations ont été enregistrées!'
    );

    return $this->redirect($this->generateUrl('invitation_index2')); 
}

but i seems not working, because I have this error :

An exception occurred while executing 'INSERT INTO invitation (created_at, updated_at, text) VALUES (?, ?, ?)' with params ["2016-08-01 17:12:55", "2016-08-01 17:12:55", null]:

SQLSTATE[23000]: Integrity constraint violation: 1048 Le champ 'text' ne peut être vide (null) !!! because text is null , and I don't get it

please use Request injection in you controllers, 'request' in the container has been deprecated in favor of the 'request_stack' — NDM

I believe that you pass your data wrong in js side. Try to change data to this:

$.ajax({
   (...)
    data : {
        ev: ev,
        text: text
    }
});

(You are using POST method, you don't pass arguments in query string in this method)

EDIT:

Your controller action should look like:

public function enregistrerInvAction(Request $request){
    (...)
    $text = $request->request->get('text');
    (...)
}

Are you sure that valid data is coming from request? (you can try to do var_dump($_POST))

check my edit. Did you check firebug or other tool if valid request is sent to server?

think you , but look at this : Controller "Invitation\InvitationBundle\Controller\InvitationController::enregistrerInvAction()" requires that you provide a value for the "$request" argument (because there is no default value or because there is a non optional argument after this one). I tried with : public function enregistrerInvAction(Request $request) and my controller give this after using :var_dump($_POST) , array (size=0) empty it means that I don't receive any data!!!

you need to type hint the $request parameter, I've updated the answer to reflect this

As described in the doc here, you can try:

// Better use the request passed on the controller's method signature
$request = $this->get('request');

 $ev = $request->request->get('ev');
 $text = $request->request->get('text');

instead of:

$request = $this->get('request');

$ev = $request->get('ev');
$text = $request->get('text');

Hope this help
