Help: PHP question

Flavs83 · #1 15-Jan-2008, 12:30

Hey all,

I dont know how to elaborate it. I am trying to make a link interact with php just like this forum.

For example a link http://www.example/index.php?board=10.0 with two topics. The topics have links (http://www.example/index.php?topic=189.0) AND (http://www.example/index.php?topic=188.0) which have same "index.php" and ONLY differ from "?topic="numbers. Clicking on the link will take/load the page.

Can anyone explains how does it work with the code?

Thank You.

This works by running a query on the database, pulling the topic from the id.

So, here's a quick example:

PHP Code:


<?php

$topic_id = $_GET['topic'];

if (!$topic_id)
{
    // Error, or display the main page, there was no topic specified
}
else 
{
    // There was a topic specified, so lets get that topic from the database and show it!
    $sql = 'SELECT * FROM topics WHERE id =' . $topic_id ;
}



?>
