How to use pre_get_space_used filter in WordPress

Example 1: Basic Usage of pre_get_space_used

In this example, we define a function weplugins_modify_pre_get_space_used_defaults that modifies the space used. We then register this function with the hook.

    function weplugins_modify_pre_get_space_used_defaults($space_used) { 
        // Update the $space_used variable according to your website requirements and return this variable.
        return $space_used; 
    }
    // add the filter
    add_filter( "pre_get_space_used", "weplugins_modify_pre_get_space_used_defaults", 10, 1 );
    

Example 2: Removing a Hook Callback

Sometimes you might need to remove a registered hook. Here’s how you can do it using remove_filter.

    remove_filter( "pre_get_space_used", "weplugins_modify_pre_get_space_used_defaults", 10, 1 );
    

Ensure you provide the same callback function name, priority, and number of arguments when removing the hook callback.

Example 3: Conditional Space Update

Here’s an example of how you can conditionally modify the $space_used variable based on certain conditions.

    function weplugins_modify_pre_get_space_used_conditionally($space_used) { 
        if ($space_used > 1000) {
            $space_used = 1000; // Limit the space used to 1000 MB for certain conditions
        }
        return $space_used; 
    }
    // add the filter
    add_filter( "pre_get_space_used", "weplugins_modify_pre_get_space_used_conditionally", 10, 1 );
