Getting images in a module

[heldercervantes]

Hey guys. Another noob question about modules.

I'm making a module that, when a page is saved, generates a json file that will be read from an outside app to get the latest news. I'm almost there, got the module working and generating the json file nicely, but I'm still struggling with images.

Basically I want to output something like `$page->image->size(300,300)->url`, but that doesn't work saying size isn't available in this context. So I tried passing it without the size, but then the url only outputs the image's assets directory, not the file itself. Couldn't find anything in the docs ?

I guess because you are in a module you have output formatting OFF which means that $page->image is an array of images and not a single PageImage object. Using $page->image->first()->size should work.

PS: To make everything clear and reduce chances for errors you can be more verbose and use $page->getUnformatted('image')->first()...

PPS: Better check if an image was uploaded before using ->size(...)

$img = $page->getUnformatted('image');
if($img AND $img->count()) {
  $img = $img->first();
  $img->size(...)->...
}

That's it! Thanks. I owe you a beer ?

I'm going to staple this to my head!

Please don't ? We have a new way of doing that, because ->getUnformatted() also gets temporary items, which is likely not what you want.

This is how to do it in recent versions: $page->get("images.first") --> I've searched hard but did not find the blog post about it ? Anyone?
