Assign the address of the uploaded image to a variable and write a judgment. If the form submission data operation is successful, the uploaded image will not be deleted, otherwise the uploaded image will be deleted.

When will that be judged? Only if you submit it will you know. If you don’t submit it, you won’t know.

You can put it in the specified folder and search for useful pictures. The rest are useless and you can delete them

Thanks! But it feels a bit difficult to query all the images used in the project.
