I am trying to have a pagination system for my practice webapp. In doing so, I stumbled upon
this.
Upon implementation in my own practice webapp, I noticed that line 3 which is
$limit = isset($_POST["limit-records"]) ? $_POST["limit-records"] : 2;
Does not accept the posted value from the select tag of the form to change the limit value of the query and directly goes into the "2" whenever I use the pagination links to change the page value. (I don't have a lot of data, so for testing I am using 2)
For example, by default I have the page set up right now to automatically limit queries by 2 only. If I select 3 to be the limit, it will limit the query by 3 in the first page. But if I use any of the pagination link, the limit will be 2 again instead of 3.
I need it to be so that whatever the user selects in the select option, it will automatically be the limit value even when I go to the next page.
What I have tried:
This is my current code as of now
