As I was posting a solution in the MODx forums this morning I realized that I have never posted the use of the randomDoc snippet here. This is a simple and useful snippet that I have used in many instances. It randomly returns a single document within a directory. You should have all the standard MODx fields (and I believe Template Variables too) available to you.
<?php // snippet RandomDoc // returns content from a random document // from a given folder // usage [!RandomDoc?folder=`xxx`!] // if $folder is not set, uses current doc ID as folder $folder = isset($folder)?$folder:$modx->documentIdentifier; $docs = $modx->getActiveChildren($folder); // get a random document id $rnd = rand(1, count($docs)); $rnd -=1; // because we need to start at 0 in the array $randomDocId = $docs[$rnd]['id']; // get the content of the random doc $contentRow = $modx->getPageInfo($randomDocId,1,'link_attributes,pagetitle, introtext,id'); $ret = ''; $ret .= '<span id="verse-title">'.$contentRow['pagetitle'].'</span><br />'; $ret .= '<span id="verse-content">'.$contentRow['introtext'].'</span>'; $ret .= ''; return $ret; ?>
This snippet hasn’t been developed to the point of having a tpl file available to control the output. To date I have hand code the output in the $ret section of the code.
You can see an example on the Valley View Church of Christ site. The snippet controls the Daily Bible Verse feature. On my sites I have found this to be a quick and easy solution for adding a nice random effect to a site.

I was not able to track down the original source for the randomDoc snippet, so I am linking to my previous article on this topic (randomDoc Snippet). [...]
