Content Protector Plugin

The Passster plugin allows users to password-protect a portion of a Page or Post. This is done by adding a shortcode that you wrap
around the content you want to protect. Your users are shown an access form in which to enter a password; if it’s correct, the protected content
will get displayed.

Features

  • Set up multiple protected sections on a single Post
  • Set cookies so users won’t need to re-enter the password on every visit, and share authorization with groups of protected sections.
  • Apply custom CSS to your forms
  • Choose from a variety of encryption methods for your passwords (depending on your server configuration)
  • Set custom passwords to authorize your visitors

A TinyMCE dialog is included to help users build the shortcode. See the Screenshots tab for more info.

Usage

NOTE: The shortcode can be built using the built-in TinyMCE dialog. When in doubt, use the dialog to create correctly formed shortcodes.

Shortcode

[content_protector password="{string}" identifier="{string}" cookie_expires="{string|int}"]...[/content_protector]
  • password – Specifies the password that unlocks the protected content. Upper- and lower-case Latin alphabet letters (A-Z and a-z), numbers (0-9), and “.” and “/” only. Set password to “CAPTCHA” to add a CAPTCHA to your access form.
  • identifier (Optional) – Used to differentiate between multiple instances of protected content
  • cookie_expires (Optional) – If set, put a cookie on the user’s computer so the user doesn’t need to re-enter the password when revisiting the page.

Template/Conditional Tag

content_protector_is_logged_in( $password = "", $identifier = "", $post_id = "", $cookie_expires = "" )
  • $password, $cookie_expires, and $identifier are defined the same as their analogous attributes above. $post_id is the Post ID.
  • Returns true if the user is currently authorized to access the content protected by a Passster shortcode matching those parameters.
  • All arguments are required.

Notes

  1. cookie_expires can be either a string or an integer. If it’s an integer, it’s processed as the number of seconds before the cookie expires; set it to “0” to make the cookie
    expire when the browser is closed. If it’s a string, it can be either a duration (e.g., “2 weeks”)
  2. While the use of identifier is optional, you must set it if you want to apply custom CSS with a specific access form, or to use Shared Authorization.
  3. While you don’t need to set identifier if you want to want to set a cookie for specific protected content, editing that content in the future will invalidate any
    cookies set for it (this may actually be desired behaviour, depending on what you’re trying to do).
  4. Basically, when in doubt, set the identifier attribute. You’ll thank yourself later.
  5. When you set an identifier for protected content, the identifier gets appended onto the existing DOM IDs in its access form. For example if you set identifier="Bob"
    in a shortcode, the ID for that form element will be #content-protector-access-form-Bob
  6. Any identifiers you set on shortcodes you use in a specific post should be unique to that post (see Note 5).
