im currently trying out some stuff with Kirby CMS.
Right now I'm trying to build a simple blog with some pictures and what i want to achieve, is that the first, and only the first picture in the blog post, ist shown in the post overview together with a short excerpt from the text.
So Im using the $page->images() function from kirby, which gives me the urls from all the pictures in the post. But I want only the first picture! Because i cant find any documented options to do that with the kirby functions i tried to do it in php.
what i figured out:
-kirby returns an object.
-i couldnt find any php-method to slice something from an object so i tried to convert it to an array:
$pictureArray = (array) $article->images();
-then i tried to use array_slice, which returned strange results so i took a closer look at my array. print_r($pictureArray); returns this:
Array ( [pagination] => [_] => Array ( [test.jpg] => image Object ( [meta] => Array ( ) [_] => Array ( [name] => test [filename] => test.jpg [extension] => jpg [root] => /home/exampledbq/www.example.com/kirby/content/01-articles/02-zweiter-Eintrag/test.jpg [uri] => content/01-articles/02-zweiter-Eintrag/test.jpg [parent] => files Object ( [pagination] => [_] => Array ( [article.txt] => variables Object ( [meta] => Array ( ) [_] => Array ( [name] => article [filename] => article.txt [extension] => txt [root] => /home/exampledbq/www.example.com/kirby/content/01-articles/02-zweiter-Eintrag/article.txt [uri] => content/01-articles/02-zweiter-Eintrag/article.txt [parent] => files Object *RECURSION* [modified] => 1354712997 [type] => content [variables] => Array ( [title] => Der zweite Eintrag [description] => Zusammenfassung.

Anyone know what this is? i mean the image url is in there, but where the hell does all this stuff come from? when i try to echo the $page->images() function it returns only the image urls and not the whole article.
Can anybody help? maybe it is even possible to achieve this with kirby-only functions and not php?
