    Hello, I need to update a validation function in validation-functions.php file.

    I dont want to lose these changes with future updates. Is there any way I can override this function, i.e. in my child theme functions.php? This is the original function I need to override.

    function wpcf7_is_tel( $tel ) {
	$pattern = '%^[+]?' // + sign
		. '(?:\([0-9]+\)|[0-9]+)' // (1234) or 1234
		. '(?:[/ -]*' // delimiter
		. '(?:\([0-9]+\)|[0-9]+)' // (1234) or 1234
		. ')*$%';

	$result = preg_match( $pattern, trim( $tel ) );
	return apply_filters( 'wpcf7_is_tel', $result, $tel );
}

    Thank you for any help.

    Hi, readyallcz, I’m another CF7 user.

    You can hook into the wpcf7_is_tel filter like the following:

    // define the callback function 
function filter_wpcf7_is_tel( $result, $tel ) { 
    // manipulate the result 
    return $result; 
}; 
         
// add the filter 
add_filter( 'wpcf7_is_tel', 'filter_wpcf7_is_tel', 10, 2 );
