add html and script into wordpress

Question

I am new to plugin development in wordpress.

I want to add just a simple html code to wp_footer using action hook I just learned from wordpress codex.

<?php
        /* 
        Plugin Name: test
        Plugin URI: http://mysite.com
        Description: test
        Version: 1.0 
        Author: me
        Author URI: http://mysite.com
        */  

    function addbar(){
    echo '<div id="cbar">';
    echo '</div>';
    }

    if ( is_user_logged_in() ){
       add_action('wp_footer','addbar');
    } else {
    }
?>

This code does not works , it crashes my site.

i am assuming that site gone white is not crashing but there is error in the script. Please check the error log. You might find some help there. — Subash

i think as this function is in pluggable.php, that the function doesn't exist when the plugin is activated. This should mean that you just have to delay the loading of your logic.

function addbar(){
if(is_user_logged_in()){
    echo '<div id="cbar">';
    echo '</div>';
}
}

 add_action('wp_footer','addbar');
