Parameters
- $message (string) – The original message content.
- $args (array) – An array of parameters passed to the filter. It contains request parameters provided when calling the SMS API.
Example Usage
/**
* Filter to modify message
*/
$message = apply_filters('wp_sms_api_message_content', $message, $request->get_params());Example Callback Function
add_filter('wp_sms_api_message_content', function ($message, $args) {
// Check if group_ids parameter is set in the request
if (isset($args['group_ids']) && $args['group_ids']) {
// Append group-specific unsubscribe instructions to the message
$message = $message . "\nTo unsubscribe, reply STOP-{$args['group_ids']} to this SMS.";
} else {
// Append general unsubscribe instructions to the message
$message = $message . "\nTo unsubscribe, reply STOP to this SMS.";
}
// You can add more conditions and modify the message further if needed
return $message;
});Additional Examples

});Example 2: Conditional Message Modification
