How to close Browser Tab After Submitting a Form?

Question

<?php
    /* ... SQL EXECUTION TO UPDATE DB ... */
?>

<form method  = "post"
      action  = "<?=$_SERVER['php_self']?>" 
      onSubmit= "window.close();">
  ...
  <input type="submit" value="submit" />
  <input type="reset"  value="reset" />
</form>

I would like to close page after submitting the form. After running the above code the page is closed after clicking submit button, but the SQL doesn't execute.

Can anyone help me?

Answer 1

<?php    
    /* ... SQL EXECUTION TO UPDATE DB ... */

    echo "<script>window.close();</script>";
?>

and Remove the window.close() from the form onsubmit event

Answer 2

Remove onsubmit from the form tag. Change this:

<input type="submit" value="submit" />

To:

<input type="submit" value="submit" name='btnSub' />

And write this:

if(isset($_POST['btnSub']))
    echo "<script>window.close();</script>";
