PHP Uploading Files

问题

I'm having a problem uploading files in PHP. When I submit, $_FILES[] is empty. I feel like this is such a n00b question :/

My form:

<form method="post" action="uploadfile.php">
<input type="hidden" name="MAX_FILE_SIZE" value="300000" />
Image: <input name="ImageFile" type="file" /><br />
<input type="submit" value="Add Image" /><br />
</form>

Relevant php.ini:

;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;

; Whether to allow HTTP file uploads.
file_uploads = On

; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
upload_tmp_dir = "c:\php5\upload\"

; Maximum allowed size for uploaded files.
upload_max_filesize = 300M

c:\php5\upload\ is writable by IUSR_HOSTNAME

Any thoughts on what else I should check?

回答1:

Make sure your form tag has this attribute: enctype="multipart/form-data"

Without it the files will not get uploaded.
