Theme Preview

By default, the only way to see how a new theme looks on your site is to
activate it, making it visible to everyone who visits. With this plugin, it
is possible to view how a new theme looks without activating it.

TODO

Possible future enhancements:

• Add an options screen.
• Allow choice of theme to preview from a known list of installed themes.
• Provide persistent previews by setting a cookie.
• Restrict preview ability by user Roles/Capabilities.
• Child-theme friendliness.

Notes

May not work properly with child themes. This is because it will not be able
to inherit from the parent theme as it normally would.

• Tested with WordPress 3.0-alpha

1. Upload the theme-preview folder and its contents to your wp-contents/plugins directory.
2. Activate in the Plugins menu.
3. Visit your site with a special parameter added to the URL

Add query variables preview_theme and/or preview_css to your query
string. For example, if you have a theme named “My Theme”, which is
installed in your wp-content/themes/my-theme directory, add the theme’s
directory name to your URL like this:

http://example.com/index.php?preview_theme=my-theme

Sometimes, you create a new look for your site by just making new CSS, but
you keep the existing PHP files intact. In that case, you con use the
preview_css variable instead of preview_theme, or use them both
together, like this:

http://example.com/index.php?preview_theme=default&preview_css=my-theme
