Uploading Files with File Input Fields in a Form

Q

How To Write the FORM Tag Correctly for Uploading Files?

✍: FYIcenter

A

When users clicks the submit button, files specified in the <INPUT TYPE=FILE...> will be transferred from the browser to the Web server. This transferring (uploading) process is controlled by a properly written <FORM...> tag as:

  <FORM ACTION=receiving.php METHOD=post
ENCTYPE=multipart/form-data>

Note that you must specify METHOD as "post" and ENCTYPE as "multipart/form-data" in order for the uploading process to work. The following PHP code, called logo_upload.php, shows you a complete FORM tag for file uploading:

<?php
  print("<html><form
action=processing_uploaded_files.php"
    ." method=post enctype=multipart/form-data>\n");
  print("Please submit an image file a Web site logo
for"
    ." fyicenter.com:<br>\n");
  print("<input type=file
name=fyicenter_logo><br>\n");
  print("<input type=submit>\n");
  print("</form></html>\n");
?>
