So, guys, I needed the page to refresh, being a second with redirection.
In case mine is like this:
echo '<meta http-equiv="refresh" content="1;listaclientes.php">';
So far so good, I edit the registry and then it redirects to the listing, but I wanted it to give it a first refresh of 1 second and stay on the same edit page, and 3 seconds later it redirects to the listing. This is because when I edit it, it returns the page without appearing the modification made, and when it gives the refresh it returns the page of listing
I tried this way but with no result:
echo '<meta http-equiv="refresh" content="1">';
echo '<meta http-equiv="refresh" content="3;url=listaclientes.php">';
In this way he updates and leaves the same page, but when he passes the 3 seconds he does not refresh again and redirects.
