Bug #3266: Cannot upload file in php4.03b

From: blues@netease.com Operating system: linux PHP version: 3.0.14 PHP Bug Type: Feedback Needed Bug description: Cannot upload file in php4.03b Hi,here I got a problem when I try to upload file in php4 script. The form is here(exactly) below: ************************* <form method=post name="Upload" enctype="multipart/form-data"> <INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="102400"> <B>upload file:</B><br> local file: <INPUT NAME="userfile" TYPE="file" onBlur="serverFileName()"><br> remote file:<br> <INPUT NAME="fn" type="text" select() onBlur="validateFileEntry(this.value, this)"> <input type=hidden name="action" value="upload"> <input type="submit" value="upload" > </form> *************************** Well,this form works well if I just upload file using the php script which contains the form. That script also contains other functions to delete,rename,create and edit file and directory. It's something like this: somephp.php?action=deletefile&filename=filename.ext Click that url, script will delete a file named "filename.ext" using unlink() function, this is also done perfectly. But after that, the upload function doesn't work any more! I will see the variable $action 's value is still "deletefile" but not "upload" after pushed the upload button in that form. I'm using seesion at the same time , but it never changes the $action 's value, even never read value from it. Other forms without this line enctype="multipart/form-data" work perfectly. Could you tell me why?
