I hope I’m right here with my request and someone can help. I’m working on a website with Drupal, but am not a trained programmer.

I use a module which allows me to display a tooltip in Drupal. By default, this is defined as type “textfield” and therefore has a maximum of 128 characters. As I need more characters, I have changed the “textfield” into “textarea”. As a result, I have more characters available. If I save the tooltip it is recognized and displayed correctly in the frontend. Only when I edit the tooltip again, the entered text is gone.

Here’s the code (the change I made is on line 25):

<?php  /**  * @file  * module for adding a link to a block title tooltip.  */  /**  * Implements hook_form_alter().  */ function block_title_tooltip_form_alter(&$form, &$form_state, $form_id) {   if ($form_id == 'block_admin_configure' || $form_id == 'block_add_block_form') {     $block = new stdClass();     $block->module = $form['module']['#value'];     $block->delta = $form['delta']['#value'];     $title_tooltip_data = block_title_tooltip_get_data($block);     $form['settings']['block_title_tooltip'] = array(       '#type' => 'fieldset',       '#title' => t('Block Title Tooltip Settings'),       '#collapsible' => TRUE,       '#weight' => 0,       '#tree' => TRUE,     );     $form['settings']['block_title_tooltip']['title_tooltip'] = array(       '#type' => 'textarea',       '#title' => t('Title Tooltip'),       '#default_value' => $title_tooltip_data,       '#description' => t('Block Title tooltip.'),     );     if (!isset($form['block_settings']['#weight'])) {       $form['block_settings']['#weight'] = -1;     }     $form['#submit'][] = 'block_title_tooltip_form_submit';   } }  /**  * Implements hook_block_view_alter().  */ function block_title_tooltip_block_view_alter(&$data, $block) {   if (isset($data['content']) && is_array($data['content'])) {     $data['content']['#attached']['css'][] = drupal_get_path('module', 'block_title_tooltip') . '/css/block_title_tooltip.css';   } }  /**  * Implements hook_form_submit().  */ function block_title_tooltip_form_submit($form, &$form_state) {   $block = new stdClass();   $block->module = $form['module']['#value'];   $block->delta = $form_state['values']['delta'];   $title_tooltip = $form_state['values']['block_title_tooltip']['title_tooltip'];   $data = array(     'title_tooltip' => $title_tooltip,   );   if (empty($title_tooltip)) {     block_title_tooltip_delete_data($block);   }   else {     block_title_tooltip_save_data($block, $data);   } }  /**  * Function to delete block data.  *  * @param object $block  *   The block object.  */ function block_title_tooltip_delete_data($block) {   if (!isset($block->module) && !isset($block->delta)) {     return FALSE;   }   $result = db_delete('block_title_tooltip')   ->condition('module', $block->module, '=')   ->condition('delta', $block->delta, '=')   ->execute(); }  /**  * Function to save Block title tooltip data.  *  * @param object $block  *   The block object.  *  * @param array $data  *   Array containing data.  */ function block_title_tooltip_save_data($block, $data) {   if (empty($block->module) || empty($block->delta)) {     return FALSE;   }    // Remove old settings.   $result = db_delete('block_title_tooltip')   ->condition('module', $block->module)   ->condition('delta', $block->delta)   ->execute();    // Save new settings.   $result = db_insert('block_title_tooltip')   ->fields(array(       'module' => $block->module,       'delta' => $block->delta,       'tooltip' => $data,       ))     ->execute();   drupal_set_message(t('Your configuration save.')); }  /**  * Implements hook_preprocess_block().  */ function block_title_tooltip_preprocess_block(&$vars, $hook) {   global $user;   if ($hook == 'block') {     $data = block_title_tooltip_get_data($vars['block']);     if ($data) {       $vars['block']->title_tooltip = (isset($data['tooltip'])) ? $data['tooltip'] : NULL;       $vars['block']->title_tooltip = $vars['block']->title_tooltip;       $display = (isset($data['display'])) ? $data['display'] : TRUE;       if (!empty($vars['block']->title_tooltip) && $display) {         $arbitrary_array = array(           'path' => drupal_get_path('module', 'block_title_tooltip') . '/image/callout.gif',           'attributes' => array('class' => 'block_title_tooltip'),         );         $vars['block']->subject = '<div class="tooltip">' . $vars['block']->subject . '<span>' . theme('image', $arbitrary_array) . check_plain($vars['block']->title_tooltip) . '</span></div>';       }     }   } }  /**  * Function to return the data associated with a block_title_tooltip.  *  * @param object $block  *   object of Block  *  * @return array  *   A renderable array containing display_link and title_tooltip variable.  */ function block_title_tooltip_get_data($block) {   if (!isset($block->module) && !isset($block->delta)) {     return FALSE;   }   $result = db_select('block_title_tooltip', 'btt')   ->condition('btt.module', $block->module, '=')   ->condition('btt.delta', $block->delta, '=')   ->fields('btt', array('tooltip'))   ->execute()   ->fetchAssoc();   if (is_array($result)) {     return $result;   }   else {     return FALSE;   } } 

Can anyone tell me what I have to change so that the tooltip is stored properly. I suspect that under the heading “* Function to save tooltip title block data.” something needs to be adjusted.

I also get this warning (maybe it has to do with it):

Warning: htmlspecialchars() expects parameter 1 to be string, array given in check_plain() (Zeile 1573 von C:xampphtdocsdrupal722includesbootstrap.inc).

Perhaps somebody sees the mistake?
