(1/1)

Hi every body,  :)

can some one help me to modfy this sql to make it get data from the man category and it's sub categories without including the id of Each sub category  :?

this is my way

--- Code: --- AND i.cat_id IN (31,30,28,25,23,22,20,19,35,15,16,18,24,26,32,34,27,33)

--- End code ---

 I want the code to get the sub categories automaticly


--- Code: ---$sql = "SELECT i.image_id, i.user_id, i.cat_id, i.image_name, i.image_thumb_file, i.image_rating, i.image_votes, c.cat_name, u.user_name
        FROM ".IMAGES_TABLE." i, ".CATEGORIES_TABLE." c, ".USERS_TABLE." u
        WHERE i.image_active = 1 AND i.cat_id NOT IN ($cat_id_sql) AND i.cat_id = c.cat_id  AND i.user_id = u.user_id $cat_match_sql  AND i.cat_id IN (31,30,28,25,23,22,20,19,35,15,16,18,24,26,32,34,27,33)
        ORDER BY i.image_rating DESC, i.image_votes DESC
        LIMIT 20";

--- End code ---

V@nо:
maybe something like that:

--- Code: ---$sql = "SELECT i.image_id, i.user_id, i.cat_id, i.image_name, i.image_thumb_file, i.image_rating, i.image_votes, c.cat_name, u.user_name
         FROM ".IMAGES_TABLE." i, ".CATEGORIES_TABLE." c, ".USERS_TABLE." u
         WHERE i.image_active = 1 AND i.cat_id NOT IN ($cat_id_sql) AND i.cat_id = c.cat_id  AND i.user_id = u.user_id $cat_match_sql  AND (i.cat_id IN (31,30,28,25,23,22,20,19 ,35,15,16,18,24,26,32,34 ,27,33) OR c.cat_parent_id IN (31,30,28,25,23,22,20,19 ,35,15,16,18,24,26,32,34 ,27,33))
         ORDER BY i.image_rating DESC, i.image_votes DESC
         LIMIT 20";
--- End code ---

V@nо:
