How to use pre_wp_update_https_detection_errors filter in WordPress

So, you’re diving into the world of WordPress hooks and stumbled upon the pre_wp_update_https_detection_errors filter? Great choice! This hook can be a real lifesaver when you need to short-circuit the default HTTPS detection logic. Let’s explore how you can use it.

pre_wp_update_https_detection_errors filter

Returning a WP_Error from the filter will effectively short-circuit the default logic of trying a remote request to the site over HTTPS, storing the errors array from the returned WP_Error instead.

To use the pre_wp_update_https_detection_errors filter, first, you have to register it using add_filter. You can write this code into the 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 weplugins_modify_pre_wp_update_https_detection_errors_defaults which takes one parameter and we registered it using add_filter. The first parameter pre_wp_update_https_detection_errors is the name of the hook, the second parameter weplugins_modify_pre_wp_update_https_detection_errors_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the 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 the pre_wp_update_https_detection_errors filter.

Parameters

Below is the one parameter required to use this hook.

• $pre: (null|WP_Error) Error object to short-circuit detection, or null to continue with the default behavior.

Live Examples

Example 1: Basic Usage

Here’s a basic example of how you can use this hook.

    function weplugins_modify_pre_wp_update_https_detection_errors_defaults($pre) {
        // Update the $pre variable according to your website requirements and return this variable. You can modify the $pre variable conditionally too if you want.
        return $pre;
    }
    // add the filter
    add_filter("pre_wp_update_https_detection_errors", "weplugins_modify_pre_wp_update_https_detection_errors_defaults", 10, 1);
    

Example 2: Removing the Hook

To remove a hook callback, use the example below.

    remove_filter("pre_wp_update_https_detection_errors", "weplugins_modify_pre_wp_update_https_detection_errors_defaults", 10, 1);
    

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

Example 3: Conditional Modification

An example where the $pre variable is modified conditionally.

    function weplugins_modify_pre_wp_update_https_detection_errors_conditionally($pre) {
        if (some_condition()) {
            $pre = new WP_Error('custom_error', 'Custom error message');
        }
        return $pre;
    }
    // add the filter
    add_filter("pre_wp_update_https_detection_errors", "weplugins_modify_pre_wp_update_https_detection_errors_conditionally", 10, 1);
