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.
