Notes

  • Always use form_open_upload() instead of form_open() for forms containing file inputs.
  • Use multiple attribute to allow multiple file selections.
  • Use accept attribute to restrict file types (e.g., '.jpg,.png' or 'image/*').
  • For multiple files, append [] to the field name: 'images[]'.
  • Access uploaded files via $_FILES['field_name'] in your controller.
  • Configure PHP's upload_max_filesize and post_max_size for larger files.
