How to pass session variable with link

Copy linkTweet thisAlerts:
Nov 22.2007

I create a page of links by querying a database and bringing up a list of businesses. Now what I want to do is have someone click on one of the links and then bring up the specific data for that business (also in the database)
How would I encode the information needed into the link I create so it can be be used to query the database.

I am assuming I have to link a session variable to each link that will be used as my primary key to query the database the 2nd time

@jasonahouleNov 22.2007 — If you already know the following then my apologies.

Create your links with a query string containing the id of the business. Retrieve the value from the query string to get the data from the database. For example, if I have a table with businesses each will have it's own individual id. I will create the links to look like this

<a href="http://mydomain.com/business.php?id=123">Business 123</a>

Now, in the business.php page you can retrieve the value of id using $_GET['id']. Use that value to retrieve the data from the database.

I hope that answers your question.

Success!
