如何使用PHP在URL中传递变量？

Question

I have a variable called $tags, which just references from a database field. When the user clicks a link with the given $tags output in it, I want that data to be stored in a variable on the target page.

For instance, the user is on a todolist.php, that contains several tasks. They can see the parts associated with this task by clicking a link that goes to a partslist.php page. In the link, I need to contains the $tags data, so javascript on the partslist.php page knows what part to highlight.

So I need to know 1) how do I output $tags in the link of todolist.php, and 2) how do I receive that output and store it on a variable on the partslist.php page?

I have done similar POST and GET commands, but I can't quite figure this out.

Answer 1

partslist.php?tags=<?php echo urlencode($tags) ?> .. is this what you are asking ? Or there are multiple tags ? Please give examples / code blocks / links

On the partslists side you can do this :

$tags  = $_GET['tags']; // You don't need urldecode here, because $_GET is a supergobal and it is already decoded.
