Why Do You Need to Filter Out Empty Files
Why Do You Need to Filter Out Empty Files? - PHP Script Tips - Uploading Files to Web Servers
✍: FYIcenter.com
When you are processing uploaded files, you need to check for empty files, because they could be resulted from a bad upload process but the PHP engine could still give no error. For example, if a user typed a bad file name in the upload field and submitted the form, the PHP engine will take it as an empty file without raising any error. The script below shows you an improved logic to process uploaded files:
<?php $file = '\fyicenter\images\fyicenter.logo'; $error = $_FILES['fyicenter_logo']['error']; $tmp_name = $_FILES['fyicenter_logo']['tmp_name']; print("\n"); if ($error==UPLOAD_ERR_OK) { if ($_FILES['fyicenter_logo']['size'] > 0) { move_uploaded_file($tmp_name, $file); print("File uploaded.\n"); } else { print("Loaded file is empty.\n"); } } else if ($error==UPLOAD_ERR_NO_FILE) { print("No files specified.\n"); } else { print("Upload faield.\n"); } print("\n"); ?>
