Hi, I have built a site with some galleries, which can be ordered by different criteria, like place, name or date_created. This works fine, iname_1,2 or 3 can be chosen by user. Now I want to have the option to sort the images "latest image first". Setting "rsort" instead of "sort" in line 31 comes up with this error: Where is my mistake? Any idea? Here is my template: 1 <?php include(\ProcessWire\wire('files')->compile(\ProcessWire\wire("config")->paths-> root . 'site/templates/_head.php',array('includes'=>true,'namespace'=>true,'modules'=> true,'skipIfNamespace'=>true))); // include header markup ?> 2 3 <div id='haupt'> 4 5 <?php 6 7 // output 'headline' if available, otherwise 'title' 8 echo '<h1>' . $page->get('headline|title') .
