Pagination / mysql query failing - php

Question

This is a strange one, i have ammended my mysql queries to show only results "WHERE domain_available='Y' AND domain_category!='N/A' AND domain_crawler_id='0'" when i manually go in to PHPMyAdmin and do an sql query test it brings back the proper results (57) but when i run the script the rows count: echo $total_results; brings back all 1300+ results, even though i manually test in the phpmyadmin query table, it brings back the results perfectly.

I cannot see why the query works in phpmyadmin, but fails when i run the script, is there something i have overlooked, and help would be appreciated.

Answer 1

$crawlId is always set here, because you set it at the very top. You set it to '' though, which will still count as set.
So you might wanna use if(!empty($crawlId)) {...} instead of isset()
