  2. Brilliant Psycho, thats exactly what I need. Thanks very much everyone for your help.
  3. When overwrite_prevent_ordering equals 1 (CURDATE() < t1.end_date AND t1.prevent_date IS NULL) OR (CURDATE() < t1.end_date AND CURDATE() < t1.prevent_date) needs to become (CURDATE() < t1.end_date)
  4. for example SELECT t1.overwrite_prevent_ordering, t2.id, t2.title, t2.gender, t3.title AS employment_status, DATE_FORMAT(t1.start_date, '%Y-%m-%d') AS start_date, DATE_FORMAT(t1.end_date, '%Y-%m-%d') AS end_date, DATE_FORMAT(t1.early_date, '%Y-%m-%d') AS early_date, DATE_FORMAT(t1.prevent_date, '%Y-%m-%d') AS prevent_date FROM wearer_wardrobes t1 LEFT JOIN wardrobes t2 ON t1.wardrobe_id = t2.id LEFT JOIN employment_status_options t3 ON t2.employment_status = t3.id WHERE t1.wearer_id = $order_wearer_id AND ( (CURDATE() >= t1.start_date OR CURDATE() >= t1.early_date) AND ( (CURDATE() < t1.end_date AND t1.prevent_date IS NULL) OR (CURDATE() < t1.end_date AND CURDATE() < t1.prevent_date) ) )
  5. Thanks folks, I tried doing something similar Muddy_Funster and kind of got it working but it's when the overwrite_prevent_ordering = 1 comes into play. it needs to overwrite the prevent_date settings.
  6. Hi Muddy_Funster, Thanks for your reply. Yeah I know the if conditionals are not correct, I only tried to explain the logic like that as i'm not sure how else to do it. So what i'm trying to do is the following: The database has a long list of wardrobes Each wearer is assigned multiple wardrobes but with a date range of when they can view this wardrobe There might be some cases were they might be able to view this wardrobe before the start_date ie. early_date and some cases were they might be prevented from viewing the wardrobe before the end_date ie. prevent_date Hope that helps you understand
  7. Hi, I'm having trouble trying figure out this mysql query. the query is as follows SELECT t2.id, t2.title, t2.gender, t3.title AS employment_status FROM wearer_wardrobes t1 LEFT JOIN wardrobes t2 ON t1.wardrobe_id = t2.id LEFT JOIN employment_status_options t3 ON t2.employment_status = t3.id WHERE t1.wearer_id = $order_wearer_id if(t1.overwrite_prevent_ordering == 1 && t1.early_date != NULL){ AND (CURDATE() >= t1.early_date AND CURDATE() < t1.end_date) }elseif(t1.overwrite_prevent_ordering == 1){ AND (CURDATE() >= t1.start_date AND CURDATE() < t1.end_date) }elseif(t1.early_date != NULL && t1.prevent_date != NULL){ AND (CURDATE() >= t1.early_date AND CURDATE() < t1.prevent_date) }elseif(t1.early_date != NULL){ AND (CURDATE() >= t1.early_date AND CURDATE() < t1.end_date) }elseif(t1.prevent_date != NULL){ AND (CURDATE() >= t1.start_date AND CURDATE() < t1.prevent_date) }else{ AND (CURDATE() >= t1.start_date AND CURDATE() < t1.end_date) } ORDER BY t2.title ASC, t3.title ASC, t2.gender ASC Is this possible wth mysql or must I select all results and filter then out with php Thanks
