Protected Posts Logout Button [logout_btn] Shortcode

The Protected Posts Logout Button (PPLB) shortcode is designed to generate a logout button for password-protected posts. When a post is password-protected, the shortcode checks if the password has been provided. If it has, the shortcode retrieves the button’s class and text from the plugin’s options. It then applies any existing filters to the text and generates the HTML for the logout button. If no text is provided, it defaults to ‘logout’. The HTML is then returned, rendering the logout button on the post.

Shortcode: [logout_btn]

Examples and Usage

Basic example – Here is a simple usage of the shortcode to add a logout button to your post.

[logout_btn /]

Advanced examples – In this example, we are using the ‘pplb_button_class’ and ‘pplb_button_text’ options to customize the button. We’ve set the class to ‘my-logout-button’ and the text to ‘Sign Out’.

// In your functions.php
add_filter('pplb_button_html', function($html, $class, $options) {
    $class = 'my-logout-button';
    $text = 'Sign Out';
    return ' ';
}, 10, 3);

Please note that the above PHP code should be added to your theme’s functions.php file. After that, you can use the [logout_btn /] shortcode in your posts and it will display a logout button with the class ‘my-logout-button’ and the text ‘Sign Out’.
