You can add custom validation rules for your fields to ensure the data submitted meets your requirements. Here’s an example of how to validate an email field.
add_filter('wpcf7_validate_email*', 'codebykp_custom_email_validation', 10, 2);
add_filter('wpcf7_validate_email', 'codebykp_custom_email_validation', 10, 2);
function codebykp_custom_email_validation($result, $tags) {
$tag = $tags[0];
$email_value = isset($_POST[$tag]) ? $_POST[$tag] : '';
if (!is_email($email_value)) {
$result->invalidate($tag, "Please enter a valid email address.");
}
return $result;
}
