What is WordPress Hook: pre_link_target
The pre_link_target hook in WordPress is used to modify the target attribute of a link before it is generated. This allows developers to change the behavior of links on their website.
Understanding the Hook: pre_link_target
The pre_link_target hook is located in the wp-includes/formatting.php file and is called just before the target attribute of a link is generated. This allows developers to intercept the link generation process and modify the target attribute as needed.
Hook Parameters (if applicable): pre_link_target
The pre_link_target hook accepts two parameters: $target and $url. The $target parameter is the target attribute of the link, and the $url parameter is the URL of the link. Developers can modify the $target parameter before it is used to generate the link.
Hook Doesn’t Work: pre_link_target
If the pre_link_target hook doesn’t seem to be working, it could be due to the hook not being called at the expected time in the link generation process. Developers should ensure that the hook is being called in the correct location and that any modifications to the $target parameter are being properly applied.
Best Practices & Usage Notes (if applicable): pre_link_target
When using the pre_link_target hook, developers should be aware that modifying the target attribute of links can affect the accessibility and usability of their website. It is important to use this hook judiciously and consider the impact on user experience.
Usage Example: pre_link_target
“`php
function modify_link_target($target, $url) {
// Check if the link is to an external site
if (strpos($url, home_url()) !== 0) {
// Change the target attribute to open links in a new tab
$target = ‘_blank’;
}
return $target;
}
add_filter(‘pre_link_target’, ‘modify_link_target’, 10, 2);
