[Plugin: Contact Form 7] Passing validation with default values

Hello.

I have the same problem.

Form sends default values.

This code from previous topic is not working :

$values = (array) $tag['values'];

    // Value
    if ( is_a( $wpcf7_contact_form, 'WPCF7_ContactForm' ) && $wpcf7_contact_form->is_posted() ) {
        if ( isset( $_POST['_wpcf7_mail_sent'] ) && $_POST['_wpcf7_mail_sent']['ok'] )
            $value = '';
        else
            $value = stripslashes_deep( $_POST[$name] );
    } else {
        $value = isset( $values[0] ) ? $values[0] : '';
    }

    if($_POST[$name] == $values[0]) $_POST[$name]= '';

Help me pls!
