This plugin allows you to restrict selected pages on your site from view. Until the user enters a code or codes of your choice, they see the page covered by a modal backdrop.
For example, we originally developed the plugin for a fast food website, they wanted an easy way to check the post code of the customer before the custom placed an order, to save people from out of their delivery area from wasting their time placing an order which could not be delivered. You could used the plugin in many similar ways, where the site is only relevant to certain people.
As well as asking the user to enter the code, it can take the code from an url parameter, so you can restrict pages so that only users who access it by a particular link can see the content. For example if you want to direct users from Twitter to some pages on your site, you could post the link on Twitter as http://mysite.com/special-page.html?magicword=twitter, where the url parameter is 'magicword' and the value that must be supplied is 'twitter'. Anyone else will just see the modal backdrop and the challenge to enter the code.
You can choose to restrict only one page, several pages, or all pages on your site
You can choose to set a cookie when the user successfully enters the correct code, so that they are not repeatedly challenged, and you can choose the cookie lifetime.
All the text displayed in the plugin form is fully translatable, and can be overridden using Joomla language overrides
You can set one correct code only, or a list of acceptable codes. The codes can be stored as a plugin option, in a text file or a Sobi database field.
