Hello,
I use this code when i want to add a picture, but now I need to edit and delete fixed(certain) pictures. How to change a code? For example I have 100 pics, and I want to delete 51 pictures and 49 remaining pictures

This is add_album.php

Code: Select all

define("IMAGES_BIG_DIR",     "../images/Big_images/"); 
    define("IMAGES_SMALL_DIR",     "../images/Small_images/");

Doesn't look like there's anything to change there. That code is just for uploading. You need new code somewhere else for editing and for deleting.

Yes, I know. You said that in your first post. But that doesn't change the fact that the code you've posted is, while relevant, not where the new code needs to go.

How do you want to select the images to delete? Checkboxes?
