Try to make a many-to-many design : Create a table 'images_img' with id_img, name_img, accession_img ... for the images Create a table 'categories_ctg' for the categories with id_ctg, name_ctg, description_ctg ... Create a table for unifing this two imgtoctg_itc with id_itc, idimg_itc, idctg_itc
In the image insert the image id_img=1, name_img="picture1.jpg", accession_img="1031-LH0152" Insert into categories the id_ctg=1, name_ctg="Military Posters" ... id_ctg=3, name_ctg="Ontario Regiment" Insert the links between the two in the imgtoctg_itc like this id_itc=1 ;The id of the record idimg_itc=1 ; The image id idctg_itc=1 ; The category id id_itc=1 ;The id of the record idimg_itc=1 ; The image id idctg_itc=2 ; The category id id_itc=1 ;The id of the record idimg_itc=1 ; The image id idctg_itc=3 ; The category id In this case the picture is fit in all three categories. Now you have to read into the mysql manual how to use the left join, right join, inner join to retrieve all the records you need from both tables images_img and categories_ctg by passing throw the imgtoctg_itc Hope this answer your question -- ------------------------------------------------- Cristian MARIN - Developer InterAKT Online (www.interakt.ro) Tel: +4021 312.53.12 Tel/Fax: +4021 312.51.91 [EMAIL PROTECTED] "H Marc Bower" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] I know this isn't the mysql area... but many of you seem very knowledgeable in this area and I would appreciate your input... What kind of field setup should I create if I want a field which will, essentially hold several distinct items, but never a set number of them? I am going to be selecting these items (or the relational pointers to them) from a multi-select list (ie. this image belongs in the following categories). After that, I will need to output the contents of this field to an array. That part I know how to do using php as long as it's a big string, but I am guessing there is a better way to do this. From the manual, it seems that a SET field would work, but I'd need the SET to be the contents of a field from another table. For example, I have an image with an accession number of 1031-LH0152. It will fit in the categories of "Military Posters", "McLaughlin - Colonel Robert Samuel", and "Ontario Regiment". How do I get one field to hold all of the categories, and then what is the most efficient way to then transport that into an array with php? Thank you for the more-elaborate-than-just-php assistance.
