Display all WP Errors together during form validation

Sorry to bother . It was one of my other functions which was limiting the error to echo only once. Here is the previous code :

function display_message( $message = false ) {
    if( is_wp_error( $message ) ) {
        echo '<div class="error"><p>' . $message->get_error_message() . '</p></div>';   
    }

It worked fine when i changed it too :

function display_message( $message = false ) {
    if( is_wp_error( $message ) ) {
        echo '<div class="error"><p>';
        foreach ( $message->get_error_messages($code) as $error ) {
        echo $error . "<br />\n";   
        }
        echo '</p></div>';  
    }
