Below is the (very) simple form that I'm using to allow users
to upload files to my site:
-----------------------
<html>
<head>
<title>Upload Attachment</title>
</head>
<body >
<br>
<center>
<h3>Upload File</h3>
You are uploading from an unsecure server.<br>
<FORM ENCTYPE="multipart/form-data" ACTION="/upload.php" METHOD=POST
name="uploadForm">
<table border=0 width="65%">
<td colspan="4" align="center">
<input type="file" name="uploadfile" size="50">
</td></tr>
<td><br></td></tr>
<th align="center" valign="center">
<input type="submit" name="submit" value="Send This File"
onClick="document.uploadForm.upload_file_name.value =
document.uploadForm.uploadfile.value">
</th></tr>
</table>
</center>
<input type="hidden" name="upload_file_name" value="">
<input type="hidden" name="site_key"
value="d3d3LmNhcmliYmVhbnByZXN0aWdlLmNvbQ==">
<input type="hidden" name="host_key" value="cGFudGhlci53aWxkLm5ldA==">
<input type="hidden" name="db_key" value="Y2FyaWJiZWFucHJlc3RpZ2U=">
<input type="hidden" name="https_key" value="MA==">
<input type="hidden" name="reg_file"
value="d3d3LmNhcmliYmVhbnByZXN0aWdlLmNvbS9pbnRlcmFjdGl2ZS9sb2dpbi91cGxvYWRfZ
mlsZXMvcmVnaXN0ZXJfdXBsb2FkX2ZpbGUucGhw">
</form>
<br><br>
<center><a href="" onclick="window.close(); return false;">Close
Window</a></center>
<br><br>
</body>
</html>
-----------------------
The problem that I'm experiencing using the above form is that when
some users (and the problem is consistent for those users) submit the
above form, *none* of the POST variables are getting passed to the
receiving page. None of the hidden variables, not the "input type = file"
variable, _nothing_. However, the majority of my users have absolutely
no problem using this form. Just those very few.
Now, when I change this line:
<FORM ENCTYPE="multipart/form-data" ACTION="/upload.php" METHOD=POST
name="uploadForm">
to this:
<FORM ACTION="/upload.php" METHOD=POST name="uploadForm">
(ie, remove the ENCTYPE="multipart/form-data"),
all of the POST data gets sent to the receiving page for those users.
What is going on? Why is the POST data not getting sent to the server
when the ENCTYPE="multipart/form-data" is included in the form
definition? And why only for a very small subset of users?
Thanks for any insight you can give!
