I have a pagination that is quite old, I have been succesful in getting it to work with php8.1 but I have one error I can not fix, and would like some help if possible please.
The line of code causing the problem is this one.
if ($page == "") { $page = "1"; } else { $page = $page; }
[11-Jun-2024 17:52:48 UTC] PHP Warning: Undefined variable $page in /home/****/public_html/gallery.php on line 30
I am using .htaccess to make seo friendly urls.
RewriteEngine On
RewriteBase /
RewriteRule ^gallery(.+)/ /gallery/?page=$1
So gallery2/ being page 2 gallery3/ being page 3 etc. All of which work perfectly
My error occurs when I go to page 1 which I want to be just /gallery. I am assuming my error occurs because of the first line of code posted at the top of here since there is no page number so $page would be empty for the first page of the gallery.
So basically I need help with what to do with this line.
if ($page == "") { $page = "1"; } else { $page = $page; }
Thank you in advance
You need to check, if the variable $page
is actually defined at the point of evaluation. You can do that with isset()
, more specifically here !isset()
:
<?php
if (!isset($page) || $page == "") { $page = "1"; } else { $page = $page; }
echo $page;
This will return "1", if $page
is not defined and not throwing a warning.
