When working with WordPress, hooks are a vital part of customizing and extending the functionality of your website. One such hook is the hidden_meta_boxes filter. This filter is used to control the list of hidden meta boxes on the WordPress admin screens. Let’s dive into how you can utilize this hook effectively.
Example 1: Modifying Hidden Meta Boxes
In this example, we’ll see how to modify the default hidden meta boxes. The function weplugins_modify_hidden_meta_boxes_defaults is created to adjust the array of hidden meta boxes.
function weplugins_modify_hidden_meta_boxes_defaults($hidden, $screen, $use_defaults) {
// Update the $hidden variable according to your website requirements and return this variable.
return $hidden;
}
// add the filter
add_filter( "hidden_meta_boxes", "weplugins_modify_hidden_meta_boxes_defaults", 10, 3 );
Example 2: Removing a Hook Callback
If you need to remove an existing hook callback, you can do so using the remove_filter function. This is useful when you want to stop a specific function from modifying the hidden meta boxes.
remove_filter( "hidden_meta_boxes", "weplugins_modify_hidden_meta_boxes_defaults", 10, 3 );
Example 3: Conditional Modification of Meta Boxes
Here’s an example where the hidden meta boxes are modified conditionally based on the current screen.
function weplugins_conditional_hidden_meta_boxes($hidden, $screen, $use_defaults) {
if ($screen->id == 'post') {
// Modify $hidden for post screen
}
return $hidden;
}
add_filter( "hidden_meta_boxes", "weplugins_conditional_hidden_meta_boxes", 10, 3 );
Remember, using hooks like hidden_meta_boxes allows you to customize your WordPress site without altering core files, ensuring your changes remain intact during updates.
