How can I allow only certain file extensions for user file uploading? |
![]() ![]() ![]() |
Set allowed file extensions for uploaded user files in file_filter_fields. Syntax: allowed_files = ext or allowed_files = ext1|ext2|ext3 Example: In your form: … <input type="file" name="attach"> … Config file: allowed_files = gif|bmp|png file_filter_fields = attach (Picture) Result: Only *.gif, *.bmp, *.png files would be allowed for user upload.
