Custom validation is not working in Contact Form 7 in ver 4.1.1

I had a similar issue with contact form 7 custom validations. Finally landed on this post and also on official custom form 7 custom validations link here: http://contactform7.com/2015/03/28/custom-validation/.

The only update required for the code working on the earlier versions of CF7 is to replace the following line of code:

$result['reason'][$name] = 'Your custom validation message goes here';

with:

$result->invalidate( $tag, "Your custom validation message goes here." );

I have also this issue was occurred when i update the contact form 7 with 4.1.1. In the latest version of contact form 7 old custom validation code is not working.

So after very research i have found solution for this. So in your case you need to change in your code as following. May be it will be helpful for you.

add_filter('wpcf7_validate_text', 'your_validation_filter_func', 999, 2);add_filter('wpcf7_validate_text*', 'your_validation_filter_func', 999, 2);function your_validation_filter_func($result, $tag) {$type = $tag['type'];$name = $tag['name'];if ('coupon_code' == $name) {    $the_value = $_POST[$name];    $myresult = substr($the_value, 0, 3);    if ($myresult == "HIP") {        $result['valid'] = true;    } else {        $result->invalidate($tag, wpcf7_get_message('invalid_coupon_code'));    }}return $result;}add_filter('wpcf7_messages', 'mywpcf7_text_messages');function mywpcf7_text_messages($messages) {return array_merge($messages, array(    'invalid_coupon_code' => array(        'description' => __("Coupon is invalid", 'contact-form-7'),        'default' => __('Coupon seems invalid.', 'contact-form-7'))));}

 function custom_phone_validation($result,$tag){        $type = $tag['type'];        $name = $tag['name'];        if($name == 'phonenumber'){                    $phoneNumber = isset( $_POST['phonenumber'] ) ? trim( $_POST['phonenumber'] ) : '';            $the_value = preg_match("/your_reg_exp format for phone number/",$_POST[$name]);            if($phoneNumber == "" || $the_value == false ){                 $result->invalidate( $tag, "please enter vaild phone number" );            }        }        return $result;    }    add_filter('wpcf7_validate_text','custom_phone_validation', 10, 2);    add_filter('wpcf7_validate_text*', 'custom_phone_validation', 10, 2);

phonenumber -> field name

try this once.
