Schedule HTML sections to be shown or not based on a date range using a simple shortcode.
Right now the plug-in is enabled by using the rotator shortcode. For example, To specify we want to show a specific piece of HTML from 9am to 5pm you can use the following code:
[rotator start=”9am” end=”5pm”]
 Some custom HTML.
[/rotator]
Where start and end parameters are using the date format specified in the <a href="http://www.php.net/manual/en/datetime.formats.php" rel="nofollow ugc">php manual</a>, so you can specify more specific dates like showing the HTML section all Tuesday between 10am and 11am, etc. Read the Other Notes section for more information.
Note: the hour range is server based time and the default timezone is UTC, in other words, it depends on the configured time of the server, you can set that in <a href="http://en.support.wordpress.com/settings/general-settings/" rel="nofollow ugc">general settings</a> at the admin console.
There is a page available at “Settings” -> “Schedule generator” in the wp admin console with a basic form which lets you generate the short code configuring different values like start and end times, among others.
<h3>Usage</h3>
Right now the plug-in is enabled by using the rotator shortcode. For example, To specify we want to show a specific piece of HTML from 9am to 5pm you can use the following code:
[rotator start=”9am” end=”5pm”]
 Some custom HTML.
[/rotator]
That will show the contents only if the user access the blog post or page in the specified hour range.
Currently, it supports the following parameters:
<ul>
<li>start: a date to specify the start of the hour range, required.</li>
<li>end: a date to specify the end of the hour range, required.</li>
<li>visible: false to hide the html section, by default true.</li>
<li>inverse: to specify if we want to show the html section outside the our range, by default false.</li>
</ul>
Both start and end are using the date format specified in the <a href="http://www.php.net/manual/en/datetime.formats.php" rel="nofollow ugc">php manual</a>. For example, we can specify the timezone of the hour range:
[rotator start=”9am -0600″ end=”5pm -0600″]…[/rotator]
Note: Using GMT notation doesn’t work in some installations, not sure which php version is required for that to work.
