Custom “Read More” Links

This is a question I come across a lot. People want to break out of the ordinary “Read More” link, which leads to their post, and come up with something a little more creative. Well, it’s really simple if you follow these steps. The first step is to edit your posts and use a new custom field called “readmore” – the value being what you want to display instead of the standard “Read More”. Next, open up your index.php, category.php, archive.php and search.php and look for a line similar to this:

the_content("Read more");

And replace that line with this:

<?php $readmore = get_post_meta($post->ID, 'readmore', true); ?>
<?php if (!$readmore) { $readmore = 'Read More &raquo;'; } ?>
<?php the_content($readmore); ?>

Allow Only Your IP Address To Access The Admin Area

Security within WordPress is always a concern. This is a wonderful technique for anyone who is the sole administrator of their site, and doesn’t have anyone accessing the administrative area from any location other than their own. All you have to do is add your IP on line 8. You can add multiple IP Addresses if needed.

AuthUserFile /dev/null
AuthGroupFile /dev/null
AuthName "Example Access Control"
AuthType Basic
<LIMIT GET>
order deny,allow
deny from all
allow from xx.xx.xx.xx
</LIMIT>

Add an Author Bio to Each Post

If you have multiple contributors to your site, this is an excellent method to distinguish who’s who. This will help your readers understand a little more about the author and in many cases help them relate as well. Some themes come equipped with this feature, but if yours doesn’t, simply add the following to your functions.php file:

function get_author_bio ($content=''){
    global $post;

    $post_author_name=get_the_author_meta("display_name");
    $post_author_description=get_the_author_meta("description");
    $html="<div class='clearfix' id='about_author'>\n";
    $html.="<img width='80' height='80' class='avatar' src='http://www.gravatar.com/avatar.php?gravatar_id=".md5(get_the_author_email()). "&default=".urlencode($GLOBALS['defaultgravatar'])."&size=80&r=PG' alt='PG'/>\n";
    $html.="<div class='author_text'>\n";
    $html.="<h4>Author: ".$post_author_name."</h4>\n";
    $html.= $post_author_description."\n";
    $html.="</div>\n";
    $html.="<div class='clear'></div>\n";
    $content .= $html;
    }

    return $content;
}

add_filter('the_content', 'get_author_bio');

Customize Your Login Page

As nice as the WordPress logo is, it doesn’t hurt to put your own into the login page instead. This will give your site a more customized appearance and make your users / contributors who log in feel that they are at a more specific, rather than generic, site. Just place the following in your functions.php file and replace the image url:

function my_custom_login_logo() {
    echo '<style type="text/css">
        h1 a { background-image:url('.get_bloginfo('template_directory').'/images/custom-login-logo.gif) !important; }
    </style>';
}

add_action('login_head', 'my_custom_login_logo');
