How to use get_object_subtype_object_type filter in WordPress

get_object_subtype_object_type filter

The dynamic portion of the hook name, $object_type, refers to the meta object type (post, comment, term, user, or any other type with an associated meta table).

To use get_object_subtype_object_type filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_get_object_subtype_object_type_defaults which takes 2 parameters and we registered using add_filter. The first parameter get_object_subtype_object_type is name of the hook, The second parameter modify_get_object_subtype_object_type_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_filter to remove get_object_subtype_object_type filter.

Parameters

Below are the 2 parameters required to use this hook.

• $object_subtype: (string) Empty string to override.
• $object_id: (int) ID of the object to get the subtype for.

Live Examples

Example 1: Basic Usage

Below is an example of how you can use this hook.

    function weplugins_modify_get_object_subtype_object_type_defaults($object_subtype, $object_id) { 
        // Update the $object_subtype variable according to your website requirements and return this variable. You can modify the $object_subtype variable conditionally too if you want.
        return $object_subtype; 
    }
    // Add the filter
    add_filter("get_object_subtype_object_type", "weplugins_modify_get_object_subtype_object_type_defaults", 10, 2);
    

Example 2: Removing a Hook Callback

To remove a hook callback, use the example below.

    remove_filter("get_object_subtype_object_type", "weplugins_modify_get_object_subtype_object_type_defaults", 10, 2);
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3: Conditional Modification

Modify the $object_subtype variable conditionally based on the object ID.

    function weplugins_modify_get_object_subtype_object_type_conditionally($object_subtype, $object_id) {
        if ($object_id == 123) {
            $object_subtype = 'custom_subtype';
        }
        return $object_subtype;
    }
    // Add the filter
    add_filter("get_object_subtype_object_type", "weplugins_modify_get_object_subtype_object_type_conditionally", 10, 2);
