.htaccess querystring

[stig1]

I have the current rule in my htaccess

 

RewriteRule ^catalogue/([a-z0-9-]+)/([a-z0-9-]+).php$  catalogue/item.php?id1=$1&id2=$2 [L]

 

however whenever i type in the browser

 

/catalogue/computers/cases.php and then change the category to a category not in my database it still shows the item.php page but without any data - blank page.

 

How do you redirect this to a 404 or do I just write a script that if no records are found in the database redirect to the main catalogue page?

You should check your query actually found a result using mysql_num_rows.

I didnt know if htaccess would do it, cause i know i can do it the other way, just thought there might have been an easier way, instead of doing a mysql_num_rows query.

 

thanks!

That would mean that mod_rewrite would need to check for the existence of a record within your database, that's what PHP is for.
