What is WordPress Hook: pre_remote_source
The pre_remote_source hook in WordPress is used to modify the URL of a remote request before it is sent. This can be useful for adding custom parameters or headers to the request, or for modifying the URL based on certain conditions.
Understanding the Hook: pre_remote_source
The pre_remote_source hook is located in the wp-includes/class-http.php file, specifically within the request method of the WP_Http class. This means that it is called just before a remote request is made using WordPress’s HTTP API.
Hook Parameters (if applicable): pre_remote_source
The pre_remote_source hook accepts two parameters: $url and $args. The $url parameter is the URL of the remote request, and the $args parameter is an array of arguments for the request, such as headers, body, and timeout.
Hook Doesn’t Work: pre_remote_source
If the pre_remote_source hook doesn’t seem to be working, it could be due to the hook being overridden by another plugin or theme, or the remote request not being made using the WordPress HTTP API. To troubleshoot, try disabling other plugins or themes to see if they are conflicting with the hook, and ensure that the request is being made using the WordPress HTTP API.
Best Practices & Usage Notes (if applicable): pre_remote_source
When using the pre_remote_source hook, it’s important to be mindful of the impact on performance, as modifying the URL or arguments for every remote request can add overhead. It’s also important to consider the security implications of modifying remote requests, as this could potentially expose sensitive information.
Usage Example: pre_remote_source
“`php
function modify_remote_source_url( $url, $args ) {
// Add a custom parameter to the URL
$url = add_query_arg( ‘custom_param’, ‘value’, $url );
return $url;
}
add_filter( ‘pre_remote_source’, ‘modify_remote_source_url’, 10, 2 );
“`
