There is something you should know..

After you parse through the data returned by getCountries once, you can't parse the same query results a second time. The pointers are already set to the end of the data after the first while { } loop and the pointer either needs to be reset or the data stored in an array for future use during the first parse.

Thanks Kevin

PHP Code:


		
			
$countryOptions = '';

after the render worked.

Thank you nhawk for that explanation =]

Oh, I think I know - you have to repeat the 'countries' query each time. Try putting

PHP Code:


		
			
$db->data_seek($getCountries, 0);

right after the 'editservicebit' template render.

LOL, it's too early. KH99 already caught that here :)

I need.... more.... coffee :D

Yeah, but I'm slightly embarrassed that I didn't notice that right off. To be honest I didn't even know that you could get the results of two queries at the same time like that.

A static list like the countries should really just go into the datastore as a serialized array. Just 1 time read them from the datastore (using the standard vB functions) into the $vbulletin object and you're done.

I will look into using the datastore. Thank you Marco.
