Hello, I'm creating a photo gallery and for individual photos, you may "tag" one. For example, when someone makes a stupid face in the photo, you may give the photo the "Funny" tag. Each photo may have multiple tags (e.g. "Funny", "Stupid", "Idiot"). To let users add a tag to a photo, I give them a "<SELECT>" box to choose from a list of existing tags. Obviously, if the photo already has the "Stupid" tag, I do not want tag showing up in the dropdown list. I'm having problems coming up with a good MySQL statement to get the information. The tables are as follows: MEDIA -------------- media_id media_title ...... MEDIA TAG -------------- media_id tag_id user_id USERS -------------- user_id user_handle .... Seeing as tags can be used on multiple photos, the JOIN seems to be pretty complicated. I've tried a variation of the following with incorrect results: SELECT * FROM dg_tags t LEFT JOIN (dg_media_tags mt) ON (t.tag_id = mt.tag_id AND mt.media_id != 6) ORDER BY t.tag_title What can I do to get the select box of "tags" that arent' in use for a specific photo? Thank you!
