FIX FOR DISPLAYING VERY NARROW IMAGES IN EDITOR UPLOAD FIELD (THINK HORIZONTAL GRADIENTS) - Apr 25th, 2013
|
I was having a devil of a time displaying a tall skinny .jpg (10px x 500px) that I'm using as a page background gradient.
Instead of a small thumbnail displayed in my editor upload field I was getting a really tall thumbnail and had to scroll the thumbnail to see the bottom of it (or the “remove” link)?.
Fortunately Jason Sauchuk from Interactive Tools had some insights and a fix.
He said:
"The reason for this is that the image CMS Builder displays inside the record editor comes from a function called showUploadPreview().
In this function, a width for the preview image is set. This has been hard coded to use a width of 50 in the function call. So if your image has dimensions of 10 X 500, it has an aspect ratio of 1:50. So if the preview image is given a width of 50, it has a height of 2500!
If you want to override this to use the thumbnail width, here is some code to do this. Please note that I tried this change through version 2.50, and if you upgrade your installation, this change will be overwritten.
Open up cmsAdmin/lib/menus/default/uploadList.php. Around line 101 you should see this:
<?php showUploadPreview($row, 50); ?>
You can make this change to it:
<?php $width = 50; if ($row['isImage'] && $row['hasThumbnail']) { $width = $row['thumbWidth']; } ?> <?php showUploadPreview($row, $width); ?>
this will use the images first thumbnail width. If a thumbnail doesn't exist, it will default back to 50."
That takes care of the editor upload field,. To fix the Record List view, Damon Edis from Interactive Tools offered:
The file you want to modify is list_functions.php. At: /cmsAdmin/lib/menus/default/list_functions.php
Again, make a backup of that file first, just in case.
At (or around) line 575 there is the line:
showUploadPreview($upload, 50);
You can change the 50 to be another number, or to have it show the thumbnails actual size replace the line with this:
showUploadPreview($upload, $upload['thumbWidth']);
Note: Any change to CMS Builder code will be overwritten in an upgrade so it is a good idea to create a custom code change text log so that you can make these changes again in the future if needed
