Question

I want to update a row of my tables .

When the user click on the icone of modify i want to redirect him in form that already get the information of row selected.

in the controller :

public function modifyBuAction($id){



    $entite=$this->get('entite.entiteservice')->findEntiteById($id);

    $form = $this->get('form.factory')->create(new BuType(), $entite); // On bind l'objet Entite à notre formulaire BuType

    if ('POST' == $request->getMethod()) { // Si on a posté le formulaire
        $form->bind($request);
        if ($form->isValid()) { // Si le formulaire est valide

            $this->get('entite.entiteservice')->saveEntite($entite); // On utilise notre Manager pour gérer la sauvegarde de l'objet Conge

            return $this->render('acmeBundle:admin:index.html.twig');
        }

    }

    return $this->render("acmeBundle:admin:modifyBu.html.twig",array("entite"=>$entite));

}

in the twig :

 <form action="{{ path('modify_bu') }}" method="post" id="bu_form" >


</br>

                <table class="form">

                      <tr>
                        <td class="col1">
                            <label>
                                {{ form_errors(form.nomEntite) }}
                                {{ form_label(form.nomEntite, 'Nom entite:') }} 
                            </label>
                        </td>
                        <td class="col2">
                            {{ form_widget(form.nomEntite) }}
                        </td>

                                {{ form_label(form.nomAgence, 'Nom agence:') }} 
                            </label>
                        </td>
                        <td class="col2">

You need to define your variable $request like this:

$request = $this->getRequest();

now i have another exception : An exception has been thrown during the rendering of a template ("Some mandatory parameters are missing ("id") to generate a URL for route "modify_bu"."). i want when i get the formType i get in the information of row selected how can i do it?

You are missing a setting in your path in your form, it is : {{ path('modify_bu', { 'id' : yourId }) }}

In addition, you can look to the paramConverter to simplify your controller : symfony.com/fr/doc/current/bundles/SensioFrameworkExtraBundle/…

Good, in your controller you select your entity with you id. Now, you must get your form in your view : return $this->render("acmeBundle:admin:modifyBu.html.twig",array( "entite" => $entite, "form" => $form->createView() )); And in your twig template you can show the form link this : {{ form_widget(form) }}
