ajax callback doesn't work in hook_form_alter

By TOF-intragi on 2 Mar 2012 at 08:41 UTC

Hi,

I'm trying to implement a form with a module using hook_form_alter. But i have a problem firing the ajax callback for one of my elements.

Do you know how to fire the callback ?

Here is my code:

<?php

function stage_menu() {
    
    $items['stage/proposition']= array(
        'title' => 'Nouvelle proposition',
        'page callback' => 'drupal_get_form',
        'page arguments' => array('proposition_node_form'),
        'access callback' => TRUE,
        'type' => MENU_SUGGESTED_ITEM,
);
      
    return $items;
}


function stage_form_alter(&$form, &$form_state, $form_id) {
  switch ($form_id) {
  case 'proposition_node_form':
     $form['Informations2'] = array(
    '#title' => t('Informations supplémentaires :'),
    '#type' => 'fieldset',
    '#collapsible' => TRUE,
    '#collapsed' => FALSE,
    '#states' => array(
      'visible' => array(
        ':input[name="Confirmation"]' => array('value' => 'yes'),
      ),
    ),
  );

     
        $form['field_entreprise']['#ajax'] = array(
        'callback' => 'stage_site_industriel_ajax_callback',
        'wrapper' => 'stage_site_industriel_wrapper',
    );

     $form['field_site_industriel'] = array(
            '#type' => 'markup',
            '#prefix' => '<div id="stage_site_industriel_wrapper">',
            '#suffix' => '</div>',
            '#ajax'=> array(
            'callback' => 'stage_contact_industriel_ajax_callback',
            'wrapper' => 'stage_contact_industriel_wrapper',
        ),
    );
     
     
     if (!empty($form_state['values']['field_societe'])) {
	$form['field_site']['#type']='select';
       $form['field_site']['#options'] = array(
      'CBl' => t('Carte Bancaire'),
      'Virement' => t('Virement Bancaire'),
      'NC' => t('Inconnu'),
    );
        
        
     }
     break;
 }
  return;
}

/* 
* Fonction appelée en Ajax qui permet de renvoyer la partie concernant la liste des sites
 */
function stage_site_industriel_ajax_callback($form, $form_state) {
return $form['field_site_industriel'];
}

Thanks anyway,

Ajax callback doesn't work

TOF-intragi commented 2 March 2012 at 08:58

When I change the value of my field_entreprise, the ajax callback does'nt trigger.

Change

Jaypan commented 2 March 2012 at 09:01

Change this:

$form['field_entreprise']['#ajax'] = array(
        'callback' => 'stage_site_industriel_ajax_callback',
        'wrapper' => 'stage_site_industriel_wrapper',
    );

To this:

$form['field_entreprise']['#ajax'] = array(
        'callback' => 'stage_site_industriel_ajax_callback',
        'wrapper' => 'stage_site_industriel_wrapper',
    );
die('<pre>' . print_r($form['field_entreprise'], TRUE) . '</pre>');

Then paste the output here.
