CGI::A...Display(3pm)

💅 CGI::Application::Plugin::Authentication::Display(3pm)

okay so bestie, welcome to CGI::Application::Plugin::Authentication::Display — part of the User Contributed Perl Documentation situation. yes, the name is a whole paragraph, we don't make the rules. it's the display half of the auth plugin, and it's here to make your login boxes cute instead of tangled up in your backend. 🎀

✨ NAME ✨

CGI::Application::Plugin::Authentication::Display — literally just generates the bits of HTML you need for authentication. that's it. that's the job. 💅

🌸 DESCRIPTION 🌸

the whole point of this code, and I cannot stress this enough, is to keep display code far, far away from the back-end of authentication management. like, separate kingdoms. no cap.

heads up though: this is an abstract base class, so you can't just use it on its own — it has to be used in conjunction with derived classes. and those derived classes? you've got options, bestie:

• the subclass CGI::Application::Plugin::Authentication::Display::Classic is provided to ensure backwards compatibility with the old code. it has the advantage of working out of the box but still retaining flexibility. lowkey the chill one. ✨
• the subclass CGI::Application::Plugin::Authentication::Display::Basic is provided to ensure XHTML compliance and to leave styling to CSS style-sheets. very clean, very demure. 🦋
• you can handle all the HTML side yourself, in which case this code is not even loaded. main character move honestly. 👑
• you can use derived classes in templates that have dot support, which keeps the display code close to the templates. this has other advantages too — for example one can use the enforce_protection method to mark a template as being only viewable after authentication. a number of other methods can be called from the template that provide information about the authentication status. iykyk. 🌈

🎀 METHODS 🎀

⭐ new

the constructor, obviously. it must be passed the CGI::Application object as the first non-object argument. why? because that's what allows derived modules to access the authentication information. give the constructor what it wants and everyone's happy. 🫶

⭐ login_box

this method will return the HTML for a login box that can be embedded into another page. and it's the same login box that is used in the default authen_login runmode that the plugin provides. consistent queen behavior. 👑

warning bestie: this function is not implemented in this module. one must use a derived class with an appropriate implementation of this function. don't come crying to the base class, it literally cannot. 😭

⭐ logout_form

this returns the simple bit of HTML need to have a logout button. (yes, we kept the typo energy, it's giving vintage.) the form has /?authen_logout=1 as the action, but of course this can be changed in derived modules. flexible fr fr. 💅

⭐ enforce_protection

this method is useful when the class is being used in templates to mark a certain template as for authenticated eyes only. 👀 so in HTML::Template::Plugin::Dot one might have:

<TMPL_VAR NAME="authen.enforce_protection">

and one must set authen to one of these objects via the HTML::Template::param method. if authenticated it will resolve to a simple string, otherwise it will croak. so like... behave. 💀

⭐ login_title

this returns the TITLE parameter from the LOGIN_FORM section of the config. short, sweet, iconic. 🎀

⭐ is_authenticated

⭐ username

⭐ last_login

⭐ last_access

⭐ is_login_timeout

⭐ login_attempts

these methods all provide access to the cognate methods on the authentication object. they are provided as templates might find them expressive. (translation: your templates will think they ate. 🔥)
