THE PENDING DRAFT

Normally when you post something to your blog, it shows an excerpt on the homepage together with a “Read More” Link in some form which links to the actual content.

But what if your excerpt already is the whole content you want to display and there is no more content to read. Of course you could use the_content inside your loop. That works in most situations, but in some situations you actually wan’t to check whether there is more inside the post than what you already got with your excerpt.

After a bit of fiddling around with different snippets, i came up with this solution, which still has some flaws, but works for what i used it now.

<?php if ( strlen(get_the_content()) > strlen(get_the_excerpt()) ) : ?>
  <p><a href="<?php the_permalink(); ?>" class="more-link">More</a></p>
<?php endif ?>

What it does is comparing the length of the strings of get_the_content() and get_the_excerpt() and only output our custom more link, if the content is longer.

I’m not 100% sure if this is the proper way of doing this, but it worked for me. If you know any other ways of achieving the same result, go ahead and add it in the comments.

WordPress.org Support Thread 

Sometimes you want to show a custom widget in the WordPress Dashboard. I use this function a lot, for example on client sites to provide some direct access to contact information for support or to show some custom messages to guide your clients with your theme, plugin or service. This little snippet will create a new widget and show it in the Admin Dashboard. Nothing more.

// Create the function for the content of our custom widget
function pdr_dashboard_widget_function() {
    echo "Display whatever it is you want to display inside your custom dashboard widget";
}

// Add our custom dashboard widget
function pdr_add_dashboard_widgets() {
    wp_add_dashboard_widget('pdr_dashboard_widget', 'Custom Dashboard Widget', 'pdr_dashboard_widget_function');
}

// Hook everything into the 'wp_dashboard_setup' action to register our functions
add_action('wp_dashboard_setup', 'pdr_add_dashboard_widgets' );

Put that code inside your functions.php, or inside a custom plugin and you will have a basic widget right in your WP Dashboard.
