Adding GET parameter on url with a tag

Question

I have a url that looks like this

mysite.com/index.php?page=home&gender=female&age=22

or

mysite.com/index.php?page=home&gender=female&occupation=programmer

How can I append a new parram orderby=value and order=asc using a tag like how the submit button works.

like when I click the link Name It will add new param on the link a I can sort the data by it

<a href="#">Name</a> | <a href="#">Age</a>

like how wordpresshandles it

wordpress/wp-admin/users.php?orderby=login&order=desc

Answer 1

Why don't you just build the URLs during the template render? No need for JS

eg

<a href="/index.php?occupation=programmer&orderby=name&order=desc">Name</a>

Just check the current order value when you render and invert it.

Obviously if you're using AJAX this is less useful.
