Property Photo Files with PHRETS v2 - phrets

Question

My php code, below, attemps to download all the photos for a property listing. It successfully queries the RETS server, and creates a file for each photo, but the file does not seem to be a functional image. (MATRIX requires files to be downloaded, instead of URLs.)
The list of photos below suggests that it successfully queries one listing id (47030752) for all photos that exist, (20 photos in this case). In a web browser, the files appear only as a small white square on a black background: e.g. (https://photos.atlantarealestate-homes.com/photos/PHOTO-47030752-9.jpg). The file size (4) also seems to be very low, as compared to that of a real photo.

fclose($f);
php?>
Are there any suggested changes to capture photos into the created files? This command creates the photo files:
file_put_contents("/bigdirs/fmls_pics/PHOTO-{$listing}-{$number}.jpg", "$object->getContent();");
There may be some parts of this script that wouldn't work in live production, but are sufficient for testing. This script seems to successfully query for the information needed from the RETS server. The problem is just simply that the actual files created do not seem to be functional photos.
Thanks in Advance! :)

Answer 1

Your code sample is a mix of the official documentation and a usable implementation. The problem is with this line:
$object->setContent(file_get_contents($object->getLocation()));
You should completely take that out. That's actually overriding the image you downloaded with nothing before you get a chance to save the contents to a file. With that removed, it should work as expected.
