[PHP 5.3] Formulaire Drupal, erreur mb_strlen()

[rps8484a]

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):

Code :

/**
* Define a channel form.
*/
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($sort_channel->name));
		for($i=1;$i<= $j; $i++) 
                {
                if(isset($channel[$sort_channel->idsort_of_channel][$i])) 
                       {
			//print($i);
			$options['channel_'.$i] = '';
			$enabled[] = 'channel_'.$i;
			$form['channel_'.$i]['name'] = array('#markup' => check_plain($channel[$sort_channel->idsort_of_channel][$i]));
			$form['channel_'.$i]['proportion'] = array('#title' => '','#type' => 'textfield','#size' => 10,'#id' => 'prop_'.$i ,'#name' => 'proportion[channel_'.$i.']');
			$form['channel_'.$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 )

function theme_channel_form($variables) {
 
$form = $variables['form'];
$rows = array();
foreach(element_children($form) as $chan)
{
        $sort_award = explode("_", $chan);
	if($sort_award[0] == 'sort')	{
		$row = array();
		$row[] = array('data' => drupal_render($form[$chan]['name']), 'colspan' => '9','id' => 'sort_channel_'.$chan.'','class' => 'sort_channel',);
		$rows[] = $row;
	} else	{
		if($sort_award[0] == 'channel')	{
			//print($chan); // résultat : channel_1 channel_2 channel_3 channel_4 channel_5 channel_6 channel_7 channel_8 channel_9 channel_10 channel_11 
			$row = array();
			$row[] = array('data' => drupal_render($form['enabled'][$chan]),'id' => 'channel_'.$chan.'','class' => 'checkboxes_channel',);
			$row[] = array('data' => drupal_render($form[$chan]['name']),'id' => 'name_'.$chan.'','class' => 'name_channel',);
			$row[] = array('data' => drupal_render($form[$chan]['proportion']),'id' => 'prop_'.$chan.'','class' => 'prop_channel',);
			$row[] = array('data' => '<img src="'.$module_path.'/img/info.png" alt="" /> ','id' => 'cost_'.$chan.'','class' => 'cost_channel',);
			$row[] = array('data' => drupal_render($form[$chan]['commission']),'id' => 'commission_'.$chan.'','class' => 'costs_channel');
			$row[] = array('data' => drupal_render($form[$chan]['monthly_cost']),'id' => 'monthly_cost_'.$chan.'','class' => 'costs_channel',);
			$row[] = array('data' => drupal_render($form[$chan]['cost_per_reservation']),'id' => 'cost_per_reservation_'.$chan.'','class' => 'costs_channel',);

			$row[] = array('data' => drupal_render($form[$chan]['salary_per_hour_m']),'id' => 'salary_per_hour_m'.$chan.'','class' => 'costs_channel',);
			$row[] = array('data' => drupal_render($form[$chan]['distribution_cost']),'id' => 'distribution_cost'.$chan.'','class' => 'costs_channel',);
			$row[] = array('data' => drupal_render($form[$chan]['idsort_of_channel']),'id' => 'idsort_of_channel'.$chan.'','class' => 'idsort_of_channel',);
			$rows[] = $row;
 
		}
	}
  }
 
$row = array();	
$row[] = array('data' => t('Total'),'colspan' => '2', 'class' => 'total_channel',);
$row[] = array('data' => drupal_render($form['total']),'id' => 'total_prop','class' => 'total_channel',);
$rows[] = $row;
$row = array();
$row[] = array('data' => drupal_render($form['submit']),'id' => 'cost_calculation','class' => 'total_channel', 'colspan' => '2',);
$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 :

/**

function channel_form_submit($form, &$form_state) {
 
$selectedchannels = array();
foreach (element_children($form_state['values']['enabled']) as $key) 
{
	 if ($form_state['values']['enabled'][$key]) {
		$chan = $form_state['values']['enabled'][$key];
		$idchan = explode("_", $chan); // 1
		$prop = $form_state['values']['proportion'][$key];
		$idsort_of_channel = $form_state['values']['idsort_of_channel'][$key];
 
		$channel = array(
		'idchannel' => $idchan[1],
		'name' => drupal_render($form[$chan]['name']),
		'proportion' => $prop,
		'idsort_of_channel' => $idsort_of_channel,
		);
		$selectedchannels[] = $channel;
	}
}
 
$_SESSION['selectedchannels'] = $selectedchannels;
 
}

Je pense que cette erreur vient du nom donné au champ "proportion" de mon formulaire, soit : '#name' => 'proportion[channel_'.$i.']' .

Je ne serais que te conseiller de changer le nom pour être sur de la provenance de l'erreur
