Hi all. I have this form: $form = array( //'#id', 'user_register_new2', '#method' => 'get', '#action' => '#', '#attributes' => array('onsubmit' => 'javascript: return false'), '#prefix' => '-------------------<br><div id="form_user_register_new" class="form_user_register_new">', '#suffix' => '</div>-------------------<br>' ); Note the '#id'. Without it the form is correctly rendered, with it php return me this error: PHP Fatal error: Cannot use string offset as an array in /opt/apache/htdocs/budda/includes/form.inc on line 976 This is my code: function zb_user_register($data) { return drupal_get_form('zb_user_register_form'); } function zb_user_register_form($data) { //var_dump($data); $form = array( //'#id', 'user_register_new2', '#method' => 'get', '#action' => '#', '#attributes' => array('onsubmit' => 'javascript: return false'), '#prefix' => '-------------------<br><div id="form_user_register_new" class="form_user_register_new">', '#suffix' => '</div>-------------------<br>' ); $form['firstname'] = array( '#weight' => -10, '#type' => 'textfield', '#title' => t('First name'), '#maxlength' => '60', '#description' => t('Insert here the description for this type of element'), '#required' => true, '#size' => 60, '#id' => 'firstname-field' ); return $form; } I'm using Drupal 6.10.
