Altering nodes title value

Question

I am trying to alter the title of my nodes to prevent URLS appearing in any title. This is the code I am using.

function mytemplate_preprocess_node(&$variables) {
  $node = $variables['node '];
  $variables['title'] = cleaner(check_plain($node->title));
}

cleaner() removes URLs from nodes. The above works perfectly on teasers, but not on full view or when the title is displayed in a list with other articles inside a block.

How can I make sure that the URL disappear whenever the concerned node's title is listed?

Answer 1

You need to implement both

• template_preprocess_page() : this will take care of node full view mode.
• temaplte_proprocess_node() : this will take care of node teaser view mode

In your theme template.php

function mythemename_preprocess_page(&$variables) {
  if(isset($variables['node']) && $variables['node']->type == "your content type") {
    drupal_set_title("your_title");    
  }
}

/**
 * Override or insert variables into the node template.
 */
function mythemename_preprocess_node(&$variables) {
  if($variables['type'] == "your content type") {
    $variables['title'] = "your title";
  }
}

Note:

• only changing in template_preprocess_node(), will now reflect on node teaser view as it will be overridden by page template.
• in order to change you should use drupal_set_title() instead of $variables['title'].

Answer 2

Use template_preprocess_page() in the template.php to update the page title for full view, However please don't your code for hook_preprocess_node() as that code would be required for updating the page title for teaser view.

Examples:

// Example of updating the nodes title for all content types.
function MYTHEME_preprocess_page(&$vars) {
  // Check if the variable is of node type.
  if (!empty($vars['node']) {
    $updated_title = cleaner(check_plain($node->title));
    drupal_set_title($updated_title);
  }
}

To update the page title of specific page just update the if condition as below:

if (!empty($variables['node']) && $variables['node']->type == 'CONTENT_TYPE') {
  $updated_title = cleaner(check_plain($node->title));
  drupal_set_title($updated_title);
}

The above things will update the page title at the time of rendering, however the better solution is to clear the URL's from the node title before saving (insert/update) the node so that you wont need to modified at the time of rendering:

// Using the hook_node_presave() for removing the URL's from title.
function MyModule_node_presave($node) {
  $node->title = cleaner(check_plain($node->title));
}

Note: The hook_node_presave() will help you for new nodes and the nodes those you are going to update.
