The Wordress Snippets series of posts will give you some useful code snippets for use in your projects – just copy and paste (but try to understand how they work!).

This snippet will add a stylesheet to your login page so that you can style it fully, and also change the default WordPress logo link (to wordpress.org) and title text to something of your choosing. Add it to functions.php in your template.

function custom_loginpage_logo_link($url)
{
     // Return a url; in this case the homepage url of wordpress
     return get_bloginfo('wpurl');
}
function custom_loginpage_logo_title($message)
{
     // Return title text for the logo to replace 'wordpress'; in this case, the blog name.
     return get_bloginfo('name');
}
function custom_loginpage_head()
{
     /* Add a stylesheet to the login page; add your styling in here, for example to change the logo use something like:
     #login h1 a {
          background:url(images/logo.jpg) no-repeat top;
     }
     */
     $stylesheet_uri = get_bloginfo('template_url')."/css/login.css";
     echo '<link rel="stylesheet" href="'.$stylesheet_uri.'" type="text/css" media="screen" />';
}
// Hook in
add_filter("login_headerurl","custom_loginpage_logo_link");
add_filter("login_headertitle","custom_loginpage_logo_title");
add_action("login_head","custom_loginpage_head");

How it works

We simply use the wordpress hooks on the login page (custom_loginpage_logo_link, custom_loginpage_logo_title, custom_loginpage_head) to insert our code and modify the existing title text and link to something of our own.

The Wordress Snippets series of posts will give you some useful code snippets for use in your projects – just copy and paste (but try to understand how they work!).

This snippet will add rel="nofollow" to the links in your blogroll, or those outputted by wp_list_bookmarks. Add to functions.php or your links template.

function nofollow_my_bookmarks( $links ) {
    foreach($links as $link) {
        $link->link_rel .= ' nofollow';
        $link->link_rel = trim($link->link_rel);
    }
    return $links;
}
add_filter('get_bookmarks', 'nofollow_my_bookmarks');

How it works

WordPress uses a function called get_bookmarks when it gets links for your blogroll – we use a filter to hook in and add the ‘nofollow’ rel tag.
