<?php
/**
 * @name getPageAssets
 * @description Returns a list of images or other assets for the given page
 *
 * 
 * USAGE EXAMPLES
 *
 * You can use the resize output filter to display different sizes. 
 *
 *  [[getPageAssets? &innerTpl=`<li><img src="[[+asset_id:resize=`300x500`]]" width="300" height="500" alt="[[+Asset.alt]]" /></li>`]]
 *
 * If using the "resize" output filter, you MUST call the snippet cached! Otherwise the "resize" filter attempts to operate on the placeholder
 * before it's set!
 *
 * No results: use a MODX output filter:
 *
 *  [[getPageAssets:empty=`No images found`? ]]
 
 * Available Placeholders
 * ---------------------------------------
 * e.g. to format the original image: 
 *      <img src="[[+Asset.url]]" width="[[+Asset.width]]" height="[[+Asset.height]]" alt="[[+Asset.alt]]" />
 * or the standard Thumbnail:
 *      <img src="[[+Asset.thumbnail_url]]" width="[[+Asset.thumbnail_width]]" height="[[+Asset.thumbnail_height]]" alt="[[+Asset.alt]]" />
 *
 * If needed, include the System Settings (double ++) :
 *      [[++assman.thumbnail_width]]
 *      [[++assman.thumbnail_height]]
 * e.g. <img src="[[+Asset.thumbnail_url]]" width="[[++assman.thumbnail_width]]" height="[[++assman.thumbnail_width]]" alt="[[+Asset.alt]]"/>
 * 
 * 
 *
 *
 * Parameters
 * -----------------------------
 * @param integer $page_id of the page whose images you want. Defaults to the current page.
 * @param string $outerTpl Format the Outer Wrapper of List (Optional)
 * @param string $innerTpl Format the Inner Item of List
 * @param string $firstTpl Format the first Item of List (optional : defaults to innerTpl)
 * @param string $lastTpl Format the last Item of List (optional : defaults to innerTpl)
 * @param string $onOne which tpl to use if there is only 1 result: innerTpl, firstTpl, or lastTpl. Default: innerTpl
 * @param string $group optional: limit the results to the specified group
 * @param boolean $is_active Get all active records only
 * @param boolean $is_image if true, return only images, if false, only other assets. If not set, we get everything.
 * @param int $limit Limit the records to be shown (if set to 0, all records will be pulled)
 * @param string $sort which column should we sort by?  Default: Product.seq
 * @param string $dir which direction should results be returned?  ASC or DESC (optional)

 *
 * Variables
 * ---------
 * @var $modx modX
 * @var $scriptProperties array
 *
 * Usage
 * ------------------------------------------------------------
 * To get all Images on certain page
 * [[!getPageAssets? &page_id=`[[*id]]` &outerTpl=`sometpl` &innerTpl=`othertpl` &firstCLass=`first` &is_active=`1` &limit=`0`]]
 * [[!getPageAssets? &page_id=`[[*id]]` &outerTpl=`sometpl` &innerTpl=`othertpl` &is_active=`1` &limit=`1`]]
