Hi, I am trying to order my results with two parts of code and the results will not display, the same code works on a different website so I don't think its that far off?

 

Many thanks

You have defined the query ($select) but you have not executed it. You need to call mysql_query to run a sql query on a mysql database (provided you have connected to MySQL and selected a database first)

[gristoi]

yep, no mysql_query()

[FUNKAM35]

please could you show me how o add this as been trying all sorts for past hour much appreciated

[Ch0cu3r]

Did you not bother looking at http://php.net/mysql_query to see how to use that function?

The missing code is.

$results = mysql_query($select);
