On a normal page with html code created by the processwire cms I would like to execute an external developed php file. If this page is called by a nav bar, then the php file should be loaded and executed. On a standard html page it could look like:
<hr>
<p>
<?php
require("readsql.php");
?>
</p>
<hr>
If I type this code on the backend, the commands are interpreted as pur text and they are not executed on the fronted.
