How to open a popup after the contact form 7 succesfully submitted

Question

I am using Wordpress and Contact form 7. I need to show a popup using magnificPopup js which will come after the successfully submission of the contact form. Have added an hook for the wpcf7_mail_sent, but how can I call popup to show using javascript.

Example :

In functions.php

add_action( 'wpcf7_mail_sent', 'after_send_mail_from_contact_form' );
function after_send_mail_from_contact_form($contact_form){
  // what to do here 
}

in Custom.js file

$('.pay_for_course').magnificPopup({
   disableOn: 700,
   type: 'iframe',
   mainClass: 'mfp-fade',
   removalDelay: 160,
   preloader: false,
   fixedContentPos: false
});

Answer 1

Try this #create a bootstrap modal popup then add this function in function.php

 <?php add_action( 'wp_footer', 'mycustom_wp_footer' );
function mycustom_wp_footer() {
?>
     <script type="text/javascript">
         document.addEventListener( 'wpcf7mailsent', function( event ) {
         if ( '34' == event.detail.contactFormId ) { // Change 34 to the ID of the form 
         jQuery('#myModal2').modal('show'); //this is the bootstrap modal popup id
       }
        }, false );
         </script>
       <?php  } ?>

#OR

add_action('wpcf7_mail_sent', function ($cf7) {
    // Run code after the email has been sent
 $wpcf = WPCF7_ContactForm::get_current();
$wpccfid=$wpcf->id;
    // if you wanna check the ID of the Form $wpcf->id
     if ( '34' == $wpccfid ) { // Change 34 to the ID of the form 
echo '
 <div class="modal fade in formids" id="myModal2" role="dialog" style="display:block;" tabindex="-1">
    <div class="modal-dialog">
    
      <!-- Modal content-->
      <div class="modal-content no_pad text-center">
         <button type="button" class="close" data-dismiss="modal">&times;</button>
        <div class="modal-header heading">
          <h3 class="modal-title">Message Sent!</b></h3>
        </div>
        <div class="modal-body">
             
            <div class="thanku_outer define_float text-center">
                <h3>Thank you for getting in touch!</h3>
            </div>
        </div>
        <div class="modal-footer">
        </div>
      </div>
      
    </div>
    </div>
';
    }
});
