11	+ Select different Themes for one or more, or all WordPress Pages, Posts or other non-Admin pages. Or Site Home.
12	+
13	+ == Description ==
14	+
15	+ Allows the Administrator to specify which Theme will be used on specific Pages, Posts, other non-Admin pages (such as Category or Archive pages) or Site Home; a Prefix feature allows a Theme to be selected based on the initial characters of its URL ("Prefix URL"). Also allows a Theme to be specified for All Pages or All Posts. In turn, even when a Theme is specified for All Pages or All Posts, a different Theme can still be specified for specific Pages or Posts.
16	+
17	+ Think what you could do if you could easily use more than one Theme on your WordPress web site or blog:
18	+
19	+ * Divide your site into Sections, each with its own unique look
20	+ * Style individual Pages, Posts, or other elements (Site Home, Category main page, Archive main page) with a different Theme
21	+ * Select a unique Theme for all Pages, Posts, Attachments, Category pages or Archive pages
22	+ * Make slight variations to a Theme, using Child Themes, for one or more Pages, Posts or other elements (Site Home, Category main page, Archive main page)
23	+ * Supports Multiple Stylesheets for Accessibility and other purposes (create one Child Theme for each Stylesheet)
24	+ * Test a new Theme on one or more Pages or Posts
25	+ * Convert to a new Theme a Page or Post at a time
26	+ * Host multiple mini-web sites on your WordPress site, each with a different Theme
27	+ * When a larger version of an image attachment is displayed, for example, when clicking on a gallery image thumbnail, use a different theme to display it, for one or all images attached to a Page or Post
28	+
29	+ Use with other Plugins: BuddyPress and Theme Test Drive plugins must both be Deactivated when jonradio Multiple Themes is Activated
30	+
31	+ Changing Theme Options (Widgets, Sidebars, Menus, Templates, Background, Header, etc.)?: See the FAQ (Frequently-Asked Questions) tab for important information on changing Options on Themes other than the Current Theme.
32	+
33	+ To select all Pages, Posts, Archives, Categories, etc. that begin with the same partial URL, a "Prefix URL" can be specified by selecting the Prefix checkbox when creating an entry on the Settings page for the jonradio Multiple Themes plugin. Restriction: the Prefix URL cannot contain all or part of a Query, which is the portion of a URL that begins with a question mark ("?"). Although the Prefix cannot contain a Query, URLs containing a Query will be matched by the Prefix.
34	+
35	+ If a Theme is not specified for a Page, Post, Site Home or other WordPress-displayed web page, such as Category or Archive display, the Current Theme specified in Appearance-Themes on the Admin panels will be used.
36	+
37	+ When selecting a Theme for Site Home or all or specific Pages, Posts or other non-Admin pages, the Theme must be shown in the list of Available Themes on the Appearance-Themes Admin panel. If necessary, install the Theme. In a WordPress Network (AKA Multisite), Themes must be Network Enabled before they will appear as Available Themes on individual sites' Appearance-Themes panel.
38	+
39	+ I hesitate to use the term Theme Switcher to describe this plugin, because the term has so many meanings. The jonradio Multiple Themes plugin does not alter the standard WordPress options that define what Theme is used on your WordPress site. Instead, it dynamically (and selectively) overrides that choice. Technical details aside, what this means is that deactivating or deleting the jonradio Multiple Themes plugin will instantly revert to the WordPress Current Theme that you have defined through the standard WordPress Appearance-Themes Admin panel.
40	+
41	+ == Installation ==
42	+
43	+ This section describes how to install the jonradio Multiple Themes plugin and get it working.
44	+
45	+ 1. Use "Add Plugin" within the WordPress Admin panel to download and install this jonradio Multiple Themes plugin from the WordPress.org plugin repository (preferred method). Or download and unzip this plugin, then upload the `/jonradio-multiple-themes/` directory to your WordPress web site's `/wp-content/plugins/` directory.
46	+ 1. Activate the jonradio Multiple Themes plugin through the 'Plugins' menu in WordPress. If you have a WordPress Network ("Multisite"), you can either Network Activate this plugin, or Activate it individually on the sites where you wish to use it. Activating on individual sites within a Network avoids some of the confusion created by WordPress' hiding of Network Activated plugins on the Plugin menu of individual sites.
47	+ 1. Be sure that all Themes you plan to use have been installed and are listed under Available Themes on the WordPress Appearance-Themes Admin panel. In a WordPress Network (AKA Multisite), Themes must be Network Enabled before they will appear as Available Themes on individual sites' Appearance-Themes panel.
48	+ 1. Select Themes to be used on the Plugin's "Multiple Themes plugin" page in the WordPress Admin panels, which is found in both the Appearance and Settings sections. You can also get to this page by clicking on the Settings link for this plugin on the Installed Plugins page.
49	+ 1. If you need to change Theme Options (Widgets, Sidebars, Menus, Templates, Background, Header, etc.) for any Theme other than the Current Theme, see the FAQ (Frequently-Asked Questions) tab for important information.
50	+
51	+ == Frequently Asked Questions ==
52	+
53	+ = Will this plugin work with Paid Themes? =
54	+
55	+ Yes, in most cases. But we have only tested the few Paid Themes whose authors have provided us with permission to use, without charge, their themes for test purposes. Elegant, for example, allows us to accept copies of its Themes provided by its customers who require assistance with the jonradio Multiple Themes plugin. On the other hand, some other Paid Theme authors have simply ignored our requests, despite our stated willingness to sign a non-disclosure agreement.
56	+
57	+ We do encourage you to contact us if you run into problems when using the jonradio Multiple Themes plugin with a Paid Theme, as the problem may not be unique to the Paid Theme.
58	+
59	+ To state the obvious, the cost of purchasing a license for all Paid Themes for testing purposes is prohibitive for an Open Source plugin such as this one.
60	+
61	+ = How do I change the Theme Options (Widgets, Sidebars, Menus, Background, Header, etc.) used for each Theme? =
62	+
63	+ NOTE: See the next FAQ for information on Templates.
64	+
65	+ For the Current Theme, nothing changes when using the jonradio Multiple Themes plugin. Options for the Current Theme, including Widgets, Sidebars, Menus, Background, Header and other Customizations supported by the Theme, can be modified in the Admin panel using the Appearance menu items on the left sidebar and the Customize link displayed beside the Current Theme on the Manage Themes tab of Appearance-Themes.
66	+
67	+ It is more difficult to modify Options for Active Themes that are not the Current Theme. We hope to build this functionality into the jonradio Multiple Themes plugin in a future Version, but it is not clear just how practical that is, so the best that can be said is: Maybe.
68	+
69	+ For now, there are two approaches. Except for Widgets, the first approach is the most likely to give you success. Menus, on the other hand, really work well with the first approach, and are severely restricted with the second method.
70	+
71	+ WARNING: So far, we have not received any reports of, nor have we tested, using both Method #1 and #2 on the same WordPress site. Use Caution if you plan to do so, as we cannot predict the results.
72	+
73	+ Method #1:
74	+
75	+ Set the Theme Options with Live Preview.
76	+
77	+ Note: Widgets cannot be placed using this Method.
78	+
79	+ 1. Go to Appearance-Themes-Live Preview in the Admin panels.
80	+ 1. Use the right sidebar to modify the Theme Options. Note that "Navigation" will not appear until a Custom Menu has been defined in Appearance-Menus. Navigation-Primary Navigation is where you would set the custom menu to be used for the Theme you are currently previewing.
81	+ 1. Click the Save & Activate button.
82	+ 1. Go immediately to Appearance-Themes to reactivate the Current Theme.
83	+
84	+ Method #2:
85	+
86	+ Use the Theme Test Drive plugin.
87	+
88	+ Note: this approach only allows Menus to be set for one Theme. Using this method to assign one or more menus to a Theme will unassign menus for all other Themes.
89	+
90	+ The jonradio Multiple Themes plugin (i.e. - this plugin) must be Deactivated, and the Theme Test Drive plugin installed and activated, so that each Theme can be selected with the Theme Test Drive plugin, allowing the Theme's Options to be set "as if" it were the Current Theme.
91	+
92	+ 1. Deactivate jonradio Multiple Themes
93	+ 1. Install the Theme Test Drive plugin found at http://wordpress.org/extend/plugins/theme-test-drive/
94	+ 1. Activate the Theme Test Drive plugin
95	+ 1. Go to Appearance-Theme Test Drive
96	+ 1. In the Usage section, select an alternate Theme you will be using with jonradio Multiple Themes
97	+ 1. Push the Enable Theme Drive button at the bottom
98	+ 1. Go to the WordPress Admin panel's Appearance menu (left sidebar)
99	+ 1. Make your changes to the Theme Options, including Widgets, Sidebars, Menus (see note above about Menus), Background, Header and other Customizations for this alternate Theme (which will appear as if it were the Current Theme)
100	+ 1. If you have more than one alternate Theme with Options you wish to change, repeat Steps 4-8 for each alternate Theme
101	+ 1. Deactivate the Theme Test Drive plugin
102	+ 1. Activate jonradio Multiple Themes
103	+ 1. Changes to the Options for the Current Theme can now be made normally, just as you would without either plugin
104	+ 1. Both the alternate and Current Themes should now display all Theme options properly when selected through the jonradio Multiple Themes plugin
105	+
106	+ = How do I change the Template for a specific Page or Post? =
107	+
108	+ For the Current Theme, nothing changes when using the jonradio Multiple Themes plugin. Select an alternate Template from the drop-down list in the Template field of the Page Attributes section of the Add New Page, Edit Page, Add New Post or Edit Post page of the Admin panels. Or the Template field in Quick Edit.
109	+
110	+ It is more difficult to change Templates for Pages or Posts defined with the jonradio Multiple Themes plugin to use Active Themes that are not the Current Theme. We hope to build this functionality into the jonradio Multiple Themes plugin in a future Version.
111	+
112	+ Use the Theme Test Drive plugin. The jonradio Multiple Themes plugin (i.e. - this plugin) must be Deactivated, and the Theme Test Drive plugin installed and activated, so that each Theme can be selected with the Theme Test Drive plugin, allowing the Theme's Template to be set for each Page or Post using that Theme "as if" it were the Current Theme.
113	+
114	+ 1. Deactivate jonradio Multiple Themes
115	+ 1. Install the Theme Test Drive plugin found at http://wordpress.org/extend/plugins/theme-test-drive/
116	+ 1. Activate the Theme Test Drive plugin
117	+ 1. Go to Appearance-Theme Test Drive
118	+ 1. In the Usage section, select an alternate Theme you will be using with jonradio Multiple Themes
119	+ 1. Push the Enable Theme Drive button at the bottom
120	+ 1. Go to the WordPress Admin panel's Page or Post menu (left sidebar)
121	+ 1. Make your changes to the Template field of each Page and/or Post that has been selected for this alternate Theme AND requires a non-default Template
122	+ 1. If you have more than one alternate Theme with Templates you wish to change, repeat Steps 4-8 for each alternate Theme
123	+ 1. Deactivate the Theme Test Drive plugin
124	+ 1. Activate jonradio Multiple Themes
125	+ 1. Changes to the Templates for Pages and Posts using the Current Theme can now be made normally, just as you would without either plugin
126	+ 1. Both the alternate and Current Themes should now display all Templates properly when selected through the jonradio Multiple Themes plugin
127	+
128	+ = How do I select a Theme for a Category of Posts? =
129	+
130	+ That functionality, to directly specify a Theme for a Category on the Settings page, is being investigated for a future version of the jonradio Multiple Themes plugin. But there is already a solution based on Permalinks:
131	+
132	+ 1. In the WordPress Admin panels, go to Settings-Permalinks
133	+ 1. Specify a Permalinks structure that begins with /%category%/
134	+ 1. Push the Save Changes button
135	+ 1. Go to Settings-Multiple Themes plugin
136	+ 1. In the Section "For An Individual Page, Post or other non-Admin page", select the Theme for the Category of Posts
137	+ 1. Enter the URL of the Categories page, e.g. - http://domain.com/news/
138	+ 1. Click the checkbox "Select here if URL is a Prefix"
139	+ 1. Push the Save Changes button
140	+
141	+ = How do I Edit a Theme? =
142	+
143	+ WordPress includes a built-in Theme Editor. Select Editor in the Admin panel's Appearance menu items on the left sidebar.
144	+
145	+ By default, the style.css file of the Current Theme is displayed. You can edit other Themes by selecting them in the "Select theme to edit" field and clicking the Select button.
146	+
147	+ Alternatively, you can edit any Theme on your own computer. If your computer runs Windows, NotePad++ and FileZilla run very well together, using FileZilla's View/Edit feature to provide a Theme Editor with syntax highlighting and other advanced features.
148	+
149	+ If one or more of the Active Themes have their own Theme Editor or other type of Theme Options panels, such as Elegant's epanel, please read the next FAQ.
150	+
151	+ = How do I use Elegant's epanel? =
152	+
153	+ Nothing changes for the Current Theme. epanel can be accessed just as it would be without the jonradio Multiple Themes plugin, simply by selecting the WordPress Admin panel's Appearance submenu item titled Theme Options preceded by the name of your Elegant Theme.
154	+
155	+ To make changes to other Active Themes that you will be specifying with the jonradio Multiple Themes plugin:
156	+
157	+ 1. Deactivate jonradio Multiple Themes
158	+ 1. Install the Theme Test Drive plugin found at http://wordpress.org/extend/plugins/theme-test-drive/
159	+ 1. Activate the Theme Test Drive plugin
160	+ 1. Go to Appearance-Theme Test Drive
161	+ 1. In the Usage section, select an alternate Theme you will be using with jonradio Multiple Themes
162	+ 1. Push the Enable Theme Drive button at the bottom
163	+ 1. Click on the Appearance menu item on the left sidebar of the WordPress Admin panel to refresh the submenu
164	+ 1. Click on the submenu item titled with your Elegant theme's name followed by "Theme Options"
165	+ 1. Elegant's epanel will now appear
166	+ 1. Make all the changes for this Theme, being sure to push the Save button
167	+ 1. If you have more than one alternate Theme with Options you wish to change, repeat Steps 4-10 for each alternate Theme
168	+ 1. Deactivate the Theme Test Drive plugin
169	+ 1. Activate jonradio Multiple Themes
170	+ 1. Changes to the Options for the Current Theme can now be made normally, just as you would without either plugin
171	+ 1. Both the alternate and Current Themes should now display all Theme options properly when selected through the jonradio Multiple Themes plugin
172	+
173	+ Thanks to Elegant for allowing us to test copies of any of their Themes provided by their customers.
174	+
175	+ = What happens when I change Permalinks? =
176	+
177	+ For entries you have created for individual Pages and Posts with the jonradio Multiple Themes plugin, you can subsequently change your Permalink structure or you can change the Permalink of a Page or Post, without having to change the plugin's entry. However, for other pages, such as Categories or Archives, you will have to delete your old entries and create new ones with the jonradio Multiple Themes plugin.
178	+
179	+ = I added a new entry but why doesn't it appear in the list of entries? =
180	+
181	+ If you add an entry that already exists, it merely replaces the previous entry.
182	+
183	+ = How can I change the Theme for an entry? =
184	+
185	+ Simply add the entry again, with the new Theme. It will replace the previous entry.
