   Hi WP-ists....

   I writing a simple plugin for WordPress, albeit slowly.

   I've got it writing to the database, but it's getting the info out that I can't seem to do

   In my brain, this should work:

   function displayCatImg(){
           global $wpdb;
           $getImg = $wpdb->query("SELECT imageurl FROM wp_blogcathead WHERE id = '7'");
               echo $getImg;
   }

   Basically, it should pull a URL from a new table in the WP database.

   Do I need to use foreach?
   There is only one value being taken from the database though.

   Should I be using something other than echo?

   Anyone? Class? Anyone?

   Cheers
   Toby

   Ahh $wpdb->query did it :)

   Now, another question is can I get the current category for the post I'm viewing and store it as a variable?

   Thanks

   The category ID number, rather than the name.

   I have `$category = get_the_category();
   $catid = $category[0]->cat_name;`
   That gave me the name of the category, but I want the ID number instead.
   Can I adapt the above to give me the number rather than the name?

   Fanks
