    <p>I've been modifying a class I found on Stack Overflow for varying Wordpress' excerpt length. It has been a bear (since I am new to OOP) but it finally does work and accept a 2nd parameter now to filter the read more link. What i would like to do though, is currently the output is 'the_excerpt' which echos out immediately whereever the function "my_excerpt()" is called. I'd like to add a function called "get_my_excerpt" that returns the value. I know get_the_excerpt() does exactly that, but I can't seem to make it work in this class.</p> <pre><code> /* Class that enables excerpt length parameter */ /* called via my_excerpt('length') */ class Excerpt { // Default length (by WordPress) public static $length = 55; // Default more (by WordPress) public static $more = "[...]"; // So you can call: my_excerpt('short'); public static $types = array( 'short' =&gt; 25, 'regular' =&gt; 55, 'long' =&gt; 100, 'xlong' =&gt; 200, ); // So you can call: my_excerpt('short'); public static $more_types = array( 'none' =&gt; "", 'regular' =&gt; "[...]", 'ellipse' =&gt; "...", 'permalink' =&gt; 'skip', ); /** * Sets the length for the excerpt, * then it adds the WP filter * And automatically calls the_excerpt(); * * @param string $new_length * @return void * @author Baylor Rae' */ public static function filter($new_length = 55, $new_more="[...]", $echo=TRUE) { Excerpt::$length = $new_length; Excerpt::$more = $new_more; add_filter('excerpt_length', 'Excerpt::new_length',98); add_filter('excerpt_more', 'Excerpt::new_more',99); return Excerpt::output(); } // Tells WP the new length public static function new_length() { if( isset(Excerpt::$types[Excerpt::$length]) ) return Excerpt::$types[Excerpt::$length]; else return Excerpt::$length; } // Tells WP the new more public static function new_more() { $db = new ReadMore; if( isset(Excerpt::$more_types[Excerpt::$more]) AND ( (Excerpt::$more_types[Excerpt::$more]) != "skip" ) ) return Excerpt::$more_types[Excerpt::$more]; elseif( isset(Excerpt::$more_types[Excerpt::$more]) AND ( (Excerpt::$more_types[Excerpt::$more]) == "skip" ) ) return $db-&gt;readmore(); else return Excerpt::$more; } // Echoes out the excerpt public static function output() { return get_the_excerpt(); } } // An alias to the class function get_my_excerpt($length = 55, $more="[...]") { return Excerpt::filter($length, $more); } // An alias to the class function my_excerpt($length = 55, $more="[...]") { echo get_my_excerpt($length, $more); } class ReadMore { private $title; private $permalink; private $more; public function __construct () { //$this-&gt;title = get_the_title(); //$this-&gt;permalink = get_permalink(); $temp = "..." . '&lt;a class="readmore" title="'. _('Permalink to').get_the_title() . '" href=" ' . get_permalink() . '"&gt;'._('Read the rest').'&lt;/a&gt;'; $this-&gt;more = $temp; } public function readmore() { return $this-&gt;more; } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
