Question

I’m trying to get information from mysql database using GET id.
I use the following code to check what the id is.

            $qry    = "SELECT name,country FROM databasetable WHERE uid=$id";

I get error which means that it couldn’t find any entry with the specified uid. If I change the uid to only to numbers, then it works can look it up. Example: ?id=1000000000 works fine, ?id=1kKV0LEfMi . Can’t be found Please help me

You need to change your query to have single quotes around the uid value like this

$qry = "SELECT name,country FROM databasetable WHERE uid='$id'";

That being said you also really need to look into using the newer MySQL connection support (not the mysql_* functions) and you need to learn how to escape your data so you protect against SQL injection.
