文本字段联系表7上的自定义验证

Question

I'm trying to validate a text field that only accepts a valid date eg 21-03-1980 however the validation code is not being triggered but I can't see what is wrong.

Here is the code I am using:

function custom_dob_validation_filter($result,$tag){

    $name = $tag->name;

    if($name == 'datemdy'){

        $datemdy = $_POST['datemdy'];

        if($datemdy != '') {

            if(!preg_match('/^([0-9]{1,2})\\/([0-9]{1,2})\\/([0-9]{4})$/', $datemdy)) {

                $result->invalidate( $tag, "Please Enter a Valid Date of Birth" );

            }

        }

    }

    return $result;
}   

add_filter( 'wpcf7_validate_dob*', 'custom_dob_validation_filter', 10, 2 );
add_filter( 'wpcf7_validate_dob', 'custom_dob_validation_filter', 10, 2 );

Any help would be greatly appreciated.

TIA

Answer 1

After hours of searching I have found the issue.

add_filter( 'wpcf7_validate_dob*', 'custom_dob_validation_filter', 10, 2 );
add_filter( 'wpcf7_validate_dob', 'custom_dob_validation_filter', 10, 2 );

Should be replaced with:

add_filter( 'wpcf7_validate_text*', 'custom_dob_validation_filter', 10, 2 );
add_filter( 'wpcf7_validate_text', 'custom_dob_validation_filter', 10, 2 );
