I have this code and the vip scanner gives me a warning but I can not figure out what the problem is, do you have any idea?
public function callback($data = false) {
if (false !== $data) {
$message = serialize($data);
//wp_mail( '[email protected]', $message );
}
}
Error:
An endpoint needs to return something, I'd also suggest adding a type hint to the '$data' parameter
Test:
- Return (
return) something at the end of the functioncallback.- and document the parameter
$data
For example:
/**
* @param array $data Arreglo con la info a ser enviadada por mail
* @param bool $data Si es 'false' no se enviara info por mail
*/
public function callback( $data = false ) {
if ( false !== $data ) {
$message = serialize( $data );
// wp_mail( '[email protected]', $message );
}
// Devolver algo (An endpoint needs to return something)
return true;
}
