Troubleshooting file uploads
1st, read the FAQ entry for uploading a file to make sure you have each component necessary present in your script.

Uploading files to a database:

If you are absolutely sure that all the necessary HTML form components are present,
Follow each of the steps present in this article in detail:
Go to your php.ini configuration file and locate the following snippet...
Code:
;;;;;;;;;;;;;;;;
; 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:\PHP\uploadtemp ; temporary directory for HTTP uploaded files (will use system default if not specified)
; Maximum allowed size for uploaded files.
upload_max_filesize = 2M
Verify that C:\PHP\uploadtemp exists and has the proper
write permissions. If the directory does not exist, create it and give it the proper
write permissions, or change the value of upload_tmp_dir to another directory and apply the proper
write permissions there.
Verify that file uploads are turned on via the file_uploads directive.
Verify that you are not trying to upload a file larger than 2MB in size, or larger than the value specified in upload_max_filesize.
If you can verify each of the above then you will be able to output the $_FILES superglobal after an upload attempt, as in:
Code:
echo "<pre>";
var_dump($_FILES);
echo "</pre>";
If the variable is empty, then there is a problem with one of the above. If the variable contains the various data associated with the file then the problem is elsewhere.
Be sure to
restart your HTTP server, if necessary, after applying any php.ini changes.
