- <head>
- <title>PHP Form Upload</title>
- </head>
- <body>
- <form method='post' action='upload3.PHP' enctype='multipart/form-data'>
- Select a File:
- <input type='file' name='filename' size='10' />
- <input type='submit' value='Upload' />

- if (isset($_POST['submit']))
- {
- echo "isset submit";
- }
- else
- {
- echo "NOT isset submit";
