Question about URL query string

Copy linkTweet thisAlerts:
Dec 23.2007

Hi

Suppose I have a URL

[url]http://www.mysite.com/products.php?cat=software&id=2[/url]

What should I do such that when I click on this link, the parameters cat=software and id=2 are passed as part of a query to a database manager (say MySQL) so that the database manager knows that I’m asking for:

Select * from DB where cat=’software’ and id=’2′

so that it will process the query and return the results for display? I’ve read about mod_rewrite and url query string but haven’t quite figured out. Any idea?

You also never literally paste the incoming field content directly into a SQL statement without rigorous validation beforehand.

Read up on model-view-controller. In this simple example the form is the view, the form handler is the controller and the back end database is the model.

Success!
