tried it out and works, I modified it slightly, though.
since the eregi function is deprecated, I replaced it with stripos.
You will also notice that I used the identical comparison (!== ) for PHP instead of the standard comparison (!=), because stripos can return a false positive or negative depending on positions of the string.
<?php /*------------------------------------------------------------------------------ MobileTemplateSwitcher - plugin for MODx (tested for versions: 0.9.6.3, 1.0.0) This version does not work on MODx Revolution 2.0 -------------------------------------------------------------------------------- Version 1.4.1 amendment by Noah Learner Code based on plugin originally posted by Peter Hoeflehner http://modxcms.com/extras/package/?package=557 Inspiration from this forum thread: http://modxcms.com/forums/index.php/topic,40357.0.html 1.4 Author: Everett Griffiths [email protected] www.fireproofsocks.com released to the Public Domain. DESCRIPTION: This plugin combines browser detection and a URL-parameter override to show/hide portions of any template delineated by <mobile> and <standard> tags. REQUIREMENTS and EXAMPLES: For this to have any effect, you must delineate one or more portions of your template(s) with <mobile> and <standard> tags, e.g. Template Example A: <html> <head> <title>[*pagetitle*]</title> <meta name=description content="[*description*]" /> <mobile> <link type="text/css" rel="stylesheet" href="mobile.css" /> </mobile> <standard> <link type="text/css" rel="stylesheet" href="standard_one.css" /> <link type="text/css" rel="stylesheet" href="standard_two.css" /> <script type="text/javascript" src="menu.js"></script> </standard> </head> <mobile> <body class="narrow"> </mobile> <standard> <body class="huge"> </standard> [*content*] </body> </html> OR Template Example B: <mobile>{{my_mobile_template}}</mobile> <standard>{{my_standard_template}}</standard> INSTALLATION: 1. Login to your MODx manager, create a new Plugin 2. Copy and paste the contents of this file into the "plugin code" text box. 3. Before saving the plugin, go to the plugin configuration tab; paste the following text into the "Plugin configuration:" text box: &usecookie=Use Cookie;list;yes,no;yes &url_param=URL Override Parameter (GET);text;browser &mobile_node=Mobile Node ID;text;mobile &standard_node=Standard Node ID;text;standard &force_browser_detect=Force Browser Detect;text;detect &iphone=iPhone is mobile?;list;1,0;1 &ipad=iPad is mobile?;list;1,0;0 &android=Android?;list;1,0;1 &opera=Opera Mini?;list;1,0;1 &blackberry=Blackberry?;list;1,0;1 &palm=Palm?;list;1,0;1 &windows=Windows Mobile?;list;1,0;1 4. Next, head over to the "System Events" tab and check the following event(s): * OnWebPagePrerender 5. Save the Plugin. USAGE: Without modifications, the user's browser is detected *once* and a cookie is set to store the value; if a mobile browser is detected, <standard> portions of the template will be deleted, leaving only <mobile> portions. URL parameters can override the results of the browser detection, e.g.: http://www.yoursite.com/some/page?browser=mobile http://www.yoursite.com/some/page?browser=standard http://www.yoursite.com/some/page?browser=detect "browser=mobile" will cause all portions of the template wrapped with <standard> tags to be deleted. "browser=standard" will cause all <mobile> nodes to be deleted. "browser=detect" triggers browser detection and clears the cookie. Whatever the result of browser detection will cause the respective nodes to be preserved. CONFIGURATION: Use Cookie? default is yes. Normal use (i.e. use cookie = yes) is that browser detection is run only ONCE per visitor, and the result is stored in the cookie. If the user chooses to override the template, this can be done via the URLs, e.g. mydomain.com/?browser=mobile If cookies are disabled, then the browser detection is run for each page request for each user. URL Parameter: The name of the parameter that will trigger the overrides, e.g. if this is set to 'x', then http://www.yoursite.com/some/page?x=mobile will trigger the mobile template to be used. Mobile node: default mobile. This affects your template code, e.g. <mobile></mobile> AND it affects the browser override, e.g. www.yoursite.com?browser=mobile Standard node: default standard. This affects your template code, e.g. <standard></standard> AND it affects the browser override, e.g. www.yoursite.com?browser=standard Browser Detect: default detect. This string identifies how you can force the user's browser to be detected. E.g. www.yoursite.com?browser=detect The following variables are from the script available at http://detectmobilebrowsers.mobi/ Some of its settings have been exposed for easy configuration within MODx. The function is_mobile_device has nine parameters that can be passed to it which define the way it handles different scenarios. These paramaters are: * iPad - Set to true to treat iPads as mobiles, false to treat them like full browsers or set a URL (including http://) to redirect iPads to. * iPhone - Set to true to treat iPhones as mobiles, false to treat them like full browsers or set a URL (including http://) to redirect iPhones and iPods to. * Android - Set to true to treat Android handsets as mobiles, false to treat them like full browsers or set a URL (including http://) to redirect Android and Google mobile users to. * Opera Mini - Set to true to treat Opera Mini like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Opera Mini users to. * Blackberry - Set to true to treat Blackberry like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Blackberry users to. * Palm - Set to true to treat Palm OS like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Palm OS users to. * Windows - Set to true to treat Windows Mobiles like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Windows Mobile users to. * Mobile Redirect URL - This should be full web address (including http://) of the site (or page) you want to send mobile visitors to. Leaving this blank will make the script return true when it detects a mobile. * Desktop Redirect URL - This should be full web address (including http://) of the site (or page) you want to send non-mobile visitors to. Leaving this blank will make the script return false when it fails to detect a mobile. ------------------------------------------------------------------------------*/ function

I didn’t have notification on for the topic. Sorry about that! Did you figure it out? I have used it without issues on a number of sites.
Let me know.

I’m having a friend try out the iPad detection feature on your mobile template switcher (great plugin btw!
) and right now, he’s telling me that he sees the mobile version of the site even though the iPad’s supposed to be set to view the standard version (via the plugin configuration tab). I’m gonna have to verify this for myself, but another friend has told me that he’s also seeing the mobile version of the site. Any clue as to why it’s doing this? I’m gonna do a little investigation too.Cheers,
Les]]>
Many Thanks,
Noah
Changelog
1. Code for configuration tab now includes code to configure iPads
2. Function now includes iPad with default being desktop view rather than as mobile device.
3. New Case to handle iPad

REQUIREMENTS and EXAMPLES: For this to have any effect, you must delineate one or more portions of your template(s) with <mobile> and <standard> tags, e.g. Template Example A: <html> <head> <title>[*pagetitle*]</title> <meta name=description content="[*description*]" /> <mobile> <link type="text/css" rel="stylesheet" href="mobile.css" /> </mobile> <standard> <link type="text/css" rel="stylesheet" href="standard_one.css" /> <link type="text/css" rel="stylesheet" href="standard_two.css" /> <script type="text/javascript" src="menu.js"></script> </standard> </head> <mobile> <body class="narrow"> </mobile> <standard> <body class="huge"> </standard> [*content*] </body> </html> OR Template Example B: <mobile>{{my_mobile_template}}</mobile> <standard>{{my_standard_template}}</standard> INSTALLATION: 1. Login to your MODx manager, create a new Plugin 2. Copy and paste the contents of this file into the "plugin code" text box. 3. Before saving the plugin, go to the plugin configuration tab; paste the following text into the "Plugin configuration:" text box: &usecookie=Use Cookie;list;yes,no;yes &url_param=URL Override Parameter (GET);text;browser &mobile_node=Mobile Node ID;text;mobile &standard_node=Standard Node ID;text;standard &force_browser_detect=Force Browser Detect;text;detect &iphone=iPhone is mobile?;list;1,0;1 &ipad=iPad is mobile?;list;1,0;0 &android=Android?;list;1,0;1 &opera=Opera Mini?;list;1,0;1 &blackberry=Blackberry?;list;1,0;1 &palm=Palm?;list;1,0;1 &windows=Windows Mobile?;list;1,0;1 4. Next, head over to the "System Events" tab and check the following event(s): * OnWebPagePrerender 5. Save the Plugin. USAGE: Without modifications, the user's browser is detected *once* and a cookie is set to store the value; if a mobile browser is detected, <standard> portions of the template will be deleted, leaving only <mobile> portions. URL parameters can override the results of the browser detection, e.g.: http://www.yoursite.com/some/page?browser=mobile http://www.yoursite.com/some/page?browser=standard http://www.yoursite.com/some/page?browser=detect "browser=mobile" will cause all portions of the template wrapped with <standard> tags to be deleted. "browser=standard" will cause all <mobile> nodes to be deleted. "browser=detect" triggers browser detection and clears the cookie. Whatever the result of browser detection will cause the respective nodes to be preserved. CONFIGURATION: Use Cookie? default is yes. Normal use (i.e. use cookie = yes) is that browser detection is run only ONCE per visitor, and the result is stored in the cookie. If the user chooses to override the template, this can be done via the URLs, e.g. mydomain.com/?browser=mobile If cookies are disabled, then the browser detection is run for each page request for each user. URL Parameter: The name of the parameter that will trigger the overrides, e.g. if this is set to 'x', then http://www.yoursite.com/some/page?x=mobile will trigger the mobile template to be used. Mobile node: default mobile. This affects your template code, e.g. <mobile></mobile> AND it affects the browser override, e.g. www.yoursite.com?browser=mobile Standard node: default standard. This affects your template code, e.g. <standard></standard> AND it affects the browser override, e.g. www.yoursite.com?browser=standard Browser Detect: default detect. This string identifies how you can force the user's browser to be detected. E.g. www.yoursite.com?browser=detect The following variables are from the script available at http://detectmobilebrowsers.mobi/ Some of its settings have been exposed for easy configuration within MODx. The function is_mobile_device has nine parameters that can be passed to it which define the way it handles different scenarios. These paramaters are: * iPad - Set to true to treat iPads as mobiles, false to treat them like full browsers or set a URL (including http://) to redirect iPads to. * iPhone - Set to true to treat iPhones as mobiles, false to treat them like full browsers or set a URL (including http://) to redirect iPhones and iPods to. * Android - Set to true to treat Android handsets as mobiles, false to treat them like full browsers or set a URL (including http://) to redirect Android and Google mobile users to. * Opera Mini - Set to true to treat Opera Mini like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Opera Mini users to. * Blackberry - Set to true to treat Blackberry like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Blackberry users to. * Palm - Set to true to treat Palm OS like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Palm OS users to. * Windows - Set to true to treat Windows Mobiles like a mobile, false to treat it like full browser or set a URL (including http://) to redirect Windows Mobile users to. * Mobile Redirect URL - This should be full web address (including http://) of the site (or page) you want to send mobile visitors to. Leaving this blank will make the script return true when it detects a mobile. * Desktop Redirect URL - This should be full web address (including http://) of the site (or page) you want to send non-mobile visitors to. Leaving this blank will make the script return false when it fails to detect a mobile. ------------------------------------------------------------------------------*/ function
