Hello Wordpress Developer,

I want to ask about how to send popup after wp_redirect(); I'm sending link to user for verify. I just want to let user know that the verify process is done.

Here is the code:

class edu002_verifyAccount{

    static function verify(){
        global $wpdb;
        $em = filter_input(INPUT_GET, "em");
        $tk = filter_input(INPUT_GET, "tk");
        $url = site_url();

        $registered_date = date( 'Y-m-d H:i:s', current_time( 'timestamp', 0 ) );  
        $newsletter_db = $wpdb->get_row( $wpdb->prepare("SELECT * FROM {$wpdb->prefix}newsletter_subscribe WHERE email = '$em'", ARRAY_A));


            $user_token = $wpdb->get_row( $wpdb->prepare("SELECT * FROM {$wpdb->prefix}user_token WHERE token = '$tk'", ARRAY_A));

                if(time() - $user_token->date_created < (60*60*24)){
                    $wpdb->update($wpdb->prefix . 'newsletter_subscribe', ["status" => 1, "subscribe_date" => $registered_date], ["email" => $em]);
                    $wpdb->delete($wpdb->prefix . 'user_token', ['email' => $em]);
                    //send popup



                    $wpdb->delete($wpdb->prefix . 'newsletter_subscribe', ['email' => $em]);
                    $wpdb->delete($wpdb->prefix . 'user_token', ['email' => $em]);


            } else{

                if(($tk != $user_token) === true){


        } else{

            if(($em != $newsletter_db->email) === true){




        return ob_get_clean(); 



Oh, I forgot. I'm using this hook:

add_action ('template_redirect', array( 'edu002_verifyAccount', 'verify'));

I use window.location, still not working.

All answer is much appreciated. Thank you in advance.

Best Regards

In general, the easiest way to implement such functionality is just to append some parameter to the URL using add_query_arg() and then trigger a popup at the destination if that parameter is set.

There are many, many ways to actually consume the parameter and create the popup - both via PHP as well JavaScript.

Below is an example of one such possibility, which simply adds a <dialog> element to the footer of the site if the parameter is set.

I recommend against using the example verbatim - it's not terribly optimal and glosses over compatibility issues with the <dialog> element, and generally likely takes more elbow grease to make as pretty as any UI/modal library which your site may already have available to use. It is mostly for illustrative purposes alone.

// Append a trigger parameter to the redirect URL.
// Register our new URL parameter so WordPress will parse it.
function wpse407962_add_popup_param( $vars ) {
  $vars[] = 'wpse40792_popup';

  return $vars;

add_filter( 'query_vars', 'wpse407962_add_popup_param' );

// Test for the parameter when printing the footer, and add some markup if present.
function wpse407962_popup_dialog() {
  $popup_id = get_query_var( 'wpse40792_popup' );

  if( empty( $popup_id ) )

  $messages = [
    'verification_complete' => 'Your account has been verified!'

    <dialog id="wpse407962-popup" open>
        <p><?php echo __( $messages[ $popup_id ], 'wpse407962' ); ?>

      window.addEventListener( 'DOMContentLoaded', () => {
        const dialog = document.getElementById( 'wpse407962-popup' );

      } );

add_action( 'wp_footer', 'wpse407962_popup_dialog' );

Another possibility would be to keep a popup initialization routine in globally enqueued JavaScript and triggering it JS-side by checking the URL. Or PHP-side, by checking the query var and conditionally calling wp_localize_script() to set up a JS global with the translated string.
