Advanced routing parameter handling in twig and Symfony2 - php

Question

I have this configuration:
A page containing a search field, at the submit in the same page I want a list of every result matching the research, everyone linking to a corresponding route. For example if I find 4 elements, I want that in the resulting page 4 links Azienda1, Azienda2 ecc.
Now I get this error:
An exception has been thrown during the rendering of a template ("The "ABCAziendaBundle_visualizza_azienda" route has some missing mandatory parameters ("id_azienda").") in ::base.html.twig at line 27.
500 Internal Server Error - Twig_Error_Runtime
1 linked Exception:
MissingMandatoryParametersException
Here are the key files,
#config.yml
ABCAziendaBundle_visualizza_azienda:
pattern: /visualizza_azienda/{id_azienda}
defaults: { _controller: ABCAziendaBundle:Default:showAzienda }
requirements:
id_azienda: \d+
ABCAziendaBundle_azienda_index:
pattern: /
defaults: { _controller: ABCAICAziendaBundle:Default:indexAzienda }
#DefaultController.php
public function indexAziendaAction(Request $request) {
$searchFormType = new SearchAziendaType();
$form = $this->createForm($searchFormType);
if ($request->getMethod() == 'POST')
{
$form->bindRequest($request);
if ($form->isValid())
{
$data = $form->getData();
$em = $this->getDoctrine()->getEntityManager();
$aziende = $em->getRepository('ABCAziendaBundle:Azienda')->findAziendaByAliasOrRagioneSocialeSubstring($data["search_field"]);
return $this->render('ABCAziendaBundle:Default:indexAzienda.html.twig', array('form' => $form->createView(), 'aziende' => $aziende));
}
}
return $this->render('ABCAziendaBundle:Default:indexAzienda.html.twig', array('form' => $form->createView()));
}
public function showAziendaAction($id_azienda) {
echo "non entra qui";
}

<h2>Ricerca azienda</h2>
<div id="form_container">

<input type="submit" />
</form>

Answer 1

I think its a typo on your side:
<a href="{{ path('ABCAziendaBundle_visualizza_azienda', { 'azienda_id' : azienda.id }) }}">
Should be:
<a href="{{ path('ABCAziendaBundle_visualizza_azienda', { 'id_azienda' : azienda.id }) }}">
The difference is the route parameter, you wrote azienda_id initialy, but the route parameter name is id_azienda
Should clear the error.
