Separate php page not working with php 8.1

    Before upgrading to php 8.1, I had a working clean, separate php page with only php-code on my wordpress site.
    Like this:
    mydomainname/public_html/wp-content/showlist/showlist.php

    The code will no longer accept root paths like: PLUGIN-NAME_ROOT_PATH
    This code will not work either: $rootPath = dirname(__FILE__)
    The page execution stops, codes after this will not show.
    As an example:

    <?php
require_once( CBXPHPSPREADSHEET_ROOT_PATH . 'lib/vendor/autoload.php' );
echo "Hello!";
?>

    This will NOT load the autoload part and the text Hello! will NOT show when executing.

    I also use Get methods on this particulary showlist.php page, that won’t work either.
    like:
    …. wp-content/showlist/showlist.php?Form=Portrait
    and code is:
    $get_code=$_GET['Form'] ?? '';

    If I put the require_once code on functions.php it will work.

    Anyone have a good answer to this strange problem?

    Check the error log of your hosting. There you should be able to identify the cause of the error.

    My guess is: CBXPHPSPREADSHEET_ROOT_PATH does not exist as a constant. This will throw an error.

    Thank you for the answer!

    The error log of my hosting only show errors on “wordpress” pages, not on separate php pages (even if they are inside wp-content structure, uploaded with FTP). I don’t know why the hosting is not logging those. The hosting don’t have a cpanel, they have their own (bad) solution on site management.

    The constant CBXPHPSPREADSHEET_ROOT_PATH exist, it’s part of a plugin. As I mentioned, it works in functions.php but not on separate php pages.

    I managed to get it working by creating a template page on wordpress admin panel, but I still wonder why separate php page is only working with simple php codes like echo functions but NOT with file structure functions now… not even dirname(__FILE__) or other standard file structure functions are working, instead they breaks the execution, when it worked without a problem before I upgraded to php 8.1.

    In the separate PHP file this constant does NOT exist. You call “showlist.php” directly. Without any wordpress environment. Thus, the file here can not know what this is a constant. It does not matter that this is in any file in parallel or in a subdirectory. You can simply test this by debugging. Write directly after <?php in one line

    var_dump(CBXPHPSPREADSHEET_ROOT_PATH);exit;

    and then call the file. You will probably see NULL as output.

    Ah, of course. I understand that now when you mention it.
    But how strange, that this worked before.

    Do you know if there is a way of integrate my separate php page so it “belongs” to wordpress environment? Some kind of header code on that page or like that?
    I have the working “template page” but that is not really the way I want it, it feels like a provisional solution.

    Again, thank you for the answers!

    Include wp-load.php in your file. E.g. via:

    require($_SERVER['DOCUMENT_ROOT'].'/wp-load.php');

    You should adapt the path to your system if necessary.

    WOW! Thanks, threadi!

    Simple as that!

    I wish I knew this before ripping my hair out. I’ve googled hours after hours without finding such easy solution!

    Again, thanks!
