Ok… Another question — I created my directory database and want to change the fields of listings. If I do so when there are listings in the database already using those fields, what happens?
You will not be able to use the same field key for new fields. I am not sure what you mean with “change the fields”, but if you delete a field, all listings will loose the data in that field.
Also, can I use listings’ names instead of ID’s to update listings? I don’t have IDs in my original files that were uploaded, and downloading the listings in the database to reupload them with IDs is very difficult because there are 90,000 entries.
No, that is not possible. It is very easy to update based on IDs. Export your listings, and you will see all the IDs will be there. Then change what needs changing, except post ID, and re-upload.
Thanks
