This is an abstract from the code in the generated "categories_dml.php" file from the Northwind demo (at
http://bigprof.com/demo):
Code: Select all
$data['Picture'] = PrepareUploadedFile('Picture', 204800,'jpg|jpeg|gif|png', false, '');
if($data['Picture']) createThumbnail($data['Picture'], getThumbnailSpecs('categories', 'Picture', 'tv'));
if($data['Picture']) createThumbnail($data['Picture'], getThumbnailSpecs('categories', 'Picture', 'dv'));
This code is responsible for handling the uploaded image and then creating thumbnails for it. You could resize the uploaded image by modifying the code to read:
Code: Select all
$data['Picture'] = PrepareUploadedFile('Picture', 204800,'jpg|jpeg|gif|png', false, '');
if($data['Picture']) createThumbnail($data['Picture'], array('width' => 750, 'height' => 750, 'identifier' => ''));
if($data['Picture']) createThumbnail($data['Picture'], getThumbnailSpecs('categories', 'Picture', 'tv'));
if($data['Picture']) createThumbnail($data['Picture'], getThumbnailSpecs('categories', 'Picture', 'dv'));
The second line in the modified code above resizes the uploaded image to fit in a 750x750 box (retaining the aspect ratio with no distortion) .. I haven't tested this modification, so give it a try and let me know if it doesn't work.

Sorry to dredge this old topic back up, but I'd also be very interested to get this working. Spent a bit of time on it today, couldn't get the example to work - adding;
if($data['Picture']) createThumbnail($data['Picture'], array('width' => 750, 'height' => 750, 'identifier' => ''));
Replacing the relevant fields with my own particulars. It still uploaded the file at the original size, unfortunately.
Would appreciate your input!

I sidestepped my issue by modifying the image links to open in a new tab, rather than the light box. The need to resize becomes less of an issue.
Will revisit this functionality in the future though.
