How can I make sure that nothing happens on the screen after sending an email?

Question

PHP

Good day.
Please tell me how to configure Phpmailer so that after clicking the "Send" button, nothing else happens except for sending the letter (it doesn't redirect me to other pages, no windows pop up, etc.).
At the moment, my settings_mail.php file says

if ($mail->send()){
    header("Location: https://www.google.com/"); 
}

and redirects me to the main page of Google, if this line is removed, then after sending I have a white page.
UPD. In this video, a solution to the problem using AJAX https://youtu.be/FQWO03fgUPM?t=16m45s

Answer 1

You need to hook the form's submit event and send an AJAX request when the form is clicked.
If you are using a framework, google "<framework name> AJAX Forms".
In any case, you need a basic understanding of JS (or in particular JQuery), then you can easily implement everything.

Answer 2

There are two options, it seems to me:
1) As already mentioned - use AJAX (the best option)
2) header('Location: '.$_SERVER['REQUEST_URI']);- paste instead of redirecting to Google, so the page will simply reload

Answer 3

I suspect that you have a condition for displaying the form, like this

if ($mail->send()){
    header("Location: https://www.google.com/"); 
} else {
    // show html form
}

You need to remove this condition so that the form is always displayed, or display a message about successful submission instead of a redirect. Or combine these solutions)

if ($mail->send()){
   echo 'Thank! Your message has been sent!';
}

// show html form

Well, in general, I would like to see a little more code in order to understand what the problem is.
