how to require a php file passing parameters

Question

I have a function that does something (and it is included in my files php). That function should require a php file passing parameters, but it fails and I'm not able to go ahead...

following the initial code of the function:

<?php
    function write_pdf($orientation, $initrow, $rowsperpage)
    {
        ob_start();

        require "./mypage.php?orient=$orientation&init=$initrow&nrrows=$rowsperpage"; 

        $html = ob_get_clean();

        $dompdf = new Dompdf();
        
        $dompdf->loadHtml($html);

...
...

the "mypage.php" returns the errors:

Notice:Undefined variable: orientation in C:\wamp\www\htdocs\site\mypage.php on line 8

Notice:Undefined variable: initrow in C:\wamp\www\htdocs\site\mypage.php on line 8

Notice:Undefined variable: rowsperpage in C:\wamp\www\htdocs\site\mypage.php on line 8

is there a way to do something like that? thanks!

Answer 1

You don't need to pass the parameters, as when you require the file is like its code where inside the function, so any variable defined in the function before the require, it will exists and be defined as well in your required file. So, you can directly use inside your required file the variables $orientation, $initrow, $rowsperpage.

Another way, quite ugly, is to add those vars to $_GET before require the file, assuming you're expecting to get them from $_GET:

$_GET['orient'] = $orientation;
$_GET['init'] = $initrow;
$_GET['nrrows'] = $rowsperpage;

require './mypage.php';

And my recommended way is to encapsulate your included file code in a function, so you can call it passing params. Even make a class, if included code is large and can be sliced in methods.
