upload problem with update page
I've set up the image upload fields on my update page once again following the PDF tutorial, and although the new images get written to the database and uploaded to the correct image folder, it's become an overwrite rather than an upload...
In other words, if I want to add a new image to a listing that has (say) 6 images, I browse for an image to upload in the photo7 field, and when I hit submit, it writes that one image into the database and deletes the first 6. I'm not sure how to overcome this.
Update page attached.
Thanks in advance.
