core_version_check_query_args filter

WARNING: Changing this data may result in your site not receiving security updates. Please exercise extreme caution.

To use core_version_check_query_args 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 Flipper Code, 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_core_version_check_query_args_defaults which takes 1 parameters and we registered using add_filter. The first parameter core_version_check_query_args is name of the hook, The second parameter modify_core_version_check_query_args_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.

Sometime, you have to remove a registered hook so you can use remove_filter to remove core_version_check_query_args filter.


    Below the 1 parameter is required to use this hook.

  • $query : (array) Version check query arguments.
    (string) WordPress version number.
    (string) PHP version number.
    (string) The locale to retrieve updates for.
    (string) MySQL version number.
    (string) The value of the $wp_local_package global, when set.
    (int) Number of sites on this WordPress installation.
    (int) Number of users on this WordPress installation.
    (int) Whether this WordPress installation uses Multisite.
    (int) Database version of WordPress at time of installation.

Live Example

apply_filters( 'core_version_check_query_args', array $query )

Below is an example how you can use this hook.

                        function modify_core_version_check_query_args_defaults($query) { 
                            // Update the $query variable according to your website requirements and return this variable. You can modify the $query variable conditionally too if you want.

                            return $query; 
                        // add the filter
                        add_filter( "core_version_check_query_args", "modify_core_version_check_query_args_defaults", 10, 1 );

To remove a hook callback, use the example below.

remove_filter( "core_version_check_query_args", "modify_core_version_check_query_args_defaults", 10, 1 );

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