Question

So, I’m trying to achieve a dynamic htaccess ban system, and this line of code is causing me huge problems:

$ip = mysql_query("SELECT ID FROM wp_contactform WHERE Nimi='Christian'");

When I echo it out, it gives me the following:

Resource id #3

The table contains Christian 3 times, with id’s 11, 13 and 10. What’s causing this?

Answer 1

$ip = mysql_query("SELECT ID FROM wp_contactform WHERE Nimi='Christian'");

$ip will simply retrieve the resource representing the resultset – it is not the data itself.

You will need to look into using:

$ip_array = mysql_fetch_array($ip);
$ID = $ip_array['ID'];

to get the ID.

Also keep in mind that this API (mysql_*) is deprecated, so it may be in your best interests to look into alternative MySQL libraries in PHP:

MySQLi: http://php.net/manual/en/book.mysqli.php

MySQL PDO: http://php.net/manual/en/book.mysqli.php
