File Upload type and mimes (a solution + office 2007 mime code/icons) - El Forum - 01-12-2009

I spent hours the last few days troubleshooting a really annoying file upload problem. Had a user email me asking why her powerpoint 2007 file wouldn't upload to the doc management program I wrote.
Easy fix, right? Wrong! First step was to add the 5 billion Office 2007 file extensions to my controller method:
docx|docm|dotx|dotm|xlsx|xlsm|xltx|xltm|xlsb|xlam|pptx|pptm|potx|potm|ppam|ppsx|ppsm
(your welcome)
I then grabbed all the office 2007 document icons in gif format:

(your welcome again)
Still wasn't working for her. She kept getting the file type not allowed message. I suddenly remembered the config/mimes.php. I added the mimes to the file . . .
Code:
$mimes = array( 'docm' => 'application/vnd.ms-word.document.macroenabled.12',
'docx' => 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
'dotm' => 'application/vnd.ms-word.template.macroenabled.12',
'dotx' => 'application/vnd.openxmlformats-officedocument.wordprocessingml.template',
'potm' => 'application/vnd.ms-powerpoint.template.macroenabled.12',
'potx' => 'application/vnd.openxmlformats-officedocument.presentationml.template',
'ppam' => 'application/vnd.ms-powerpoint.addin.macroenabled.12',
'ppsm' => 'application/vnd.ms-powerpoint.slideshow.macroenabled.12',
'ppsx' => 'application/vnd.openxmlformats-officedocument.presentationml.slideshow',
'pptm' => 'application/vnd.ms-powerpoint.presentation.macroenabled.12',
'pptx' => 'application/vnd.openxmlformats-officedocument.presentationml.presentation',
'xlam' => 'application/vnd.ms-excel.addin.macroenabled.12',
'xlsb' => 'application/vnd.ms-excel.sheet.binary.macroenabled.12',
'xlsm' => 'application/vnd.ms-excel.sheet.macroenabled.12',
'xlsx' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
'xltm' => 'application/vnd.ms-excel.template.macroenabled.12',
'xltx' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.template'
);(aren't I a giving person :p)
Still no dice. After hours of testing and searching these forums, I finally gave in and looked at the file_upload class (1.6.1). Turns out the class runs the uploaded file's mime type through strtolower. The mimes I copied into my mimes.php file had capital letters. I did a text replace, and it worked (the code above has already been text replaced).
Just thought I would share this with everyone else. It's not the first time that case sensitivity bit me on the a** . . . probably won't be the last either.

Thanks for the contribution, but are all browsers identifying the mimes like that?

good question. I don't know honestly. From reading these forums, it appears that there is some discrepancy between how browsers report mime types to the server. I can at least vouch for firefox 3 and IE7 working with these types in our environment.
I'm going to have to update this app eventually. If I ever get around to it, I'll try to put in the legwork to find out.

I also tried to upload an office document (excel) with the extension xlsx. It kept telling me the filetype is not allowed. I look at the upload value and the filetype is \"application/octet-stream\" instead of just application/octet-stream.
I have no idea why this is happening but I just added the string inside the mimetype.
Code:
'xlsx' => array('application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', 'application/octet-stream', '\"application/octet-stream\"'),Now it works. Anyone have any idea why this is happening?

this issue has been covered in forums before. I ran into it when I was researching my problem. I believe it has to do with how certain browsers (possibly firefox?) report mime types. It's a little over my head. If I can find a link to one of those threads, I'll post it here.

I tried the above solution but it didn't work, did some digging in the CI_Upload class and did found out that not all types were loaded, did change the order of the allowed types and this did the trick.
