Uploaded media not available in UI about scalar

[craigdietrich]

Hi!

Do you mean, the choose an image pulldown for choosing a key image or background image?

Those pulldowns determine what is an image in a rather strict way, the file extension of the uploaded files need to be .jpeg, .jpg, .gif, or .png. So, if your images don't have one of these extensions, or don't have any extension (which can happen on a mac), then they won't show up in the list.

Curious if this helps?

My book is called "test" and this is my media folder:

total 80K
drwxrwxr-x 2 apache www    4.0K May 10 15:37 .
drwxrwxr-x 3 apache www    4.0K May 10 15:15 ..
-rwxrwxr-x 1 apache apache  22K May 10 15:37 book_thumbnail.png
-rwxrwxr-x 1 apache apache  22K May 10 15:36 scholarworks.png
-rwxrwxr-x 1 apache apache  22K May 10 15:36 scholarworks_thumb.png
[root@ip-172-31-21-86 html]# 

So not sure why they aren't loading.

FYI - When I "Import Local Media File" - the upload works, the file shows up on the filesystem, but the UI doesn't indicate any success or failure, it just stays on the import page. So maybe something related to this is the problem?

[craigdietrich]

Ah, so when you try to upload a file, the upload page doesn't refresh to a new page that shows the image, once the upload is complete?

When you go to Dashboard > Media tab, do you see anything listed there?

What Scalar install are you using? One of ours (e.g., scalar.usc.edu) or a custom install?

[aaron-collier]

Right.

This is a fresh install from git master.

[aaron-collier]

Nope.

Are you familiar with the Web Inspector in your browser? If so, could you open it up and click on the Console tab? This will reveal the ajax request to the server (that comes back after the file is physically uploaded), in which case can you check to see what is returned and if there's any javascript or php error in there?

If the above is out of your league I can try to cook up a lighter weight option.

Either way there's probably a PHP error being thrown for some reason by your server, probably to do with permissions or something.

[aaron-collier]

The validation javascript is certainly failing. Getting a null result. The apache user is the owner of the file system structure, so not sure why a permissions issue would be a problem unless it's doing something outside of the app filesystem structure.

[craigdietrich]

Are you able to open up the request itself (might be under the Net tab)? If so, under the "Response", you should see something, maybe some PHP errors? Or, is the Response itself just blank?

If the response itself is blank, you can open up codeigniter.php in the root folder and switch "production" to "development" and try again: this should turn on errors.

Ah, thanks... getting somewhere. I have this error:

PHP Fatal error:  Uncaught Error: Call to undefined function imagecreatefrompng() in /var/www/html/system/application/libraries/File_Upload.php:139\nStack trace:\n#0 /var/www/html/system/application/libraries/File_Upload.php(43): File_Upload->resize('/var/www/html/t...', 200)\n#1 /var/www/html/system/application/controllers/book.php(541): File_Upload->createMediaThumb('test/', 'media/scholarwo...', 509)\n#2 /var/www/html/system/application/controllers/book.php(167): Book->upload()\n#3 /var/www/html/system/core/CodeIgniter.php(326): Book->_remap('test', Array)\n#4 /var/www/html/codeigniter.php(203): require_once('/var/www/html/s...')\n#5 {main}\n  thrown in /var/www/html/system/application/libraries/File_Upload.php on line 139, referer: http://scalar.calstate.edu/test/upload

[craigdietrich]

Ah! That's it!

Do you have access to PHP on your server? The GD Library needs to be turned on http://php.net/manual/en/book.image.php

I think thumbnail creation is the only operation that uses GD (though there's a few places that thumbnails are made).. if you can't get GD turned on I could put in the pipeline some hooks for Scalar to test whether those functions exist before trying to use them, which would remove those errors.

[aaron-collier]

FIXED!

Thanks! Was that in the docs? I missed it. That should probably be highlighted.

Thanks again!
