Formulaire Drupal, erreur mb_strlen()

**rps8484a** · 01/11/2011, 11h13

Bonjour,

Je développe en PHP pour le CMS Drupal. J'ai réalisé un formulaire avec l'API Drupal. Le formulaire s'affiche correctement, cependant je reçois l'erreur suivante :

Warning: mb_strlen() expects parameter 1 to be string, array given in drupal_strlen() (line 441 of C:\wamp\www\drupal-7.8\includes\unicode.inc).

Je pense que cette erreur vient du nom donné au champ "proportion" de mon formulaire, soit : '#name' => 'proportion[channel_'.$i.']' . Le nom étant, je le pense, considéré comme un array. Cependant j'ai été obligée de donner ce nom là pour pouvoir récupérer les données dans la fonction channel_form_submit(). Je n'arrive pas à résoudre cette erreur, quelqu'un aurait-il une idée ?

Je met le code plus complet à la suite, si besoin. Merci.

La fonction qui crée le formulaire est la suivante (je n'ai gardé ici que la partie du formulaire):

function channel_form() {
 
foreach ($result_sort_channel as $sort_channel) {
	if($sort_channel->simple == '1')	{
		$form['sort_'.$sort_channel->idsort_of_channel]['name'] = array('#markup' => check_plain($sort_channel->name));

                {

			$form['channel_'.$i]['commission'] = array('#type' => 'textfield', '#id' => 'commission_'.$i, '#default_value' => check_plain($cost[$i][1]), '#size' => 1);
			$form['channel_'.$i]['monthly_cost'] = array('#type' => 'textfield', '#id' => 'monthly_cost_'.$i, '#default_value' => check_plain($cost[$i][2]), '#size' => 1);
			$form['channel_'.$i]['cost_per_reservation'] = array('#type' => 'textfield', '#id' => 'cost_per_reservation_'.$i,'#default_value' => check_plain($cost[$i][3]), '#size' => 1);
			$form['channel_'.$i]['salary_per_hour_chf'] = array('#type' => 'textfield', '#id' => 'salary_per_hour_chf_'.$i,'#default_value' => check_plain($cost[$i][4]), '#size' => 1);
			$form['channel_'.$i]['salary_per_hour_m'] = array('#type' => 'textfield', '#id' => 'salary_per_hour_m_'.$i,'#default_value' => check_plain($cost[$i][5]), '#size' => 1);
			$form['channel_'.$i]['distribution_cost'] = array('#type' => 'textfield', '#id' => 'distribution_cost_'.$i,'#default_value' => check_plain($cost[$i][6]), '#size' => 1);
			$form['channel_'.$i]['idsort_of_channel'] = array('#type' => 'textfield', '#id' => 'idsort_of_channel'.$i,'#default_value' => check_plain($sort_channel->idsort_of_channel), '#size' => 1,'#name' => 'idsort_of_channel[channel_'.$i.']');
			}
	}
}
	}

et ici se trouve la fonction qui permet de mettre en forme le formulaire (dans mon cas, je l'insère dans un tableau )

	}
  }
 
$row = array();

$rows[] = $row;
 
$header = array( array('data' => t('title'),'id' => 't_clear',  'colspan' => '2'), array('data' => t('Proportion (%)')), array('data' => t('Informations')));
 
$output = theme('table', array('header' => $header, 'rows' => $rows,'attributes' => array('id' => 'choose_channel')));
$output .= drupal_render_children($form);
 
 
return $output;
}

Et finalement, la fonction qui récupère les données du formulaire :
