    <p>I have a plugin/function that I use for detecting if the device is mobile/tablet/desktop.</p> <p>E.g:</p> <p><code>&lt;img src="/path/to/images/foo{if detect_device == 'desktop'}-highres{/if}.jpg"</code></p> <p>Plugin</p> <pre><code>&lt;?php /* * Smarty plugin * ------------------------------------------------------------- * File: function.detect_device.php * Type: function * Name: detect_device * Purpose: Simple plugin to access Mobile_Detect methods from within templates * Examples: * {if detect_device == 'tablet'} - return string either: mobile/tablet/desktop * {if detect_device action='isAndroidOS'} - boolean * {if detect_device action='isiOS'} - boolean * ------------------------------------------------------------- */ function smarty_function_detect_device($params, &amp;$smarty) { // Include and instantiate the class. require_once 'Mobile_Detect/Mobile_Detect.php'; $detect = new Mobile_Detect; // Access specific method if(!empty($params)){ foreach($params as $param){ if(method_exists($detect, $param)){ return $detect-&gt;$param(); } } } else { // Simple device type switch (true) { case $detect-&gt;isMobile() : return 'mobile'; case $detect-&gt;isTablet() : return 'tablet'; default : return 'desktop'; } } } ?&gt; </code></pre> <p>Q1. How come this is never true <code>{if detect_device == 'desktop'}</code> but when I <code>{detect_device|@var_dump}</code> it returns string 'desktop' (length=7)? I think I am just getting mixed up with the type of plugin I should be using, since I am now wanting to pass a parameter to the plugin should I be using a modifier? I would prefer this syntax <code>{if $detect_device|isiOS}</code> but this tries to check if isiOS is a modifier instead of parameter.</p> <p>Q2. Is there a way to cache the Mobile_Detect object so that this only performs the user agent calculations once?</p> <p>Mobile detect script from: <a href="https://github.com/serbanghita/Mobile-Detect" rel="nofollow">https://github.com/serbanghita/Mobile-Detect</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
