Bug Fix – showcase.php stopped working when i moved it live, the following change fixed it:

if ( has_post_format()) {

to

if ( has_post_format('')) {

I have no idea why it worked on my local dev and not on my live site. They are supposed to be identical.

Just because this took me hours to sort out – I just posted my solution to this to another thread about custom excerpt lengths because I was having trouble getting those to show (resolved, http://wordpress.org/support/topic/custom-excerpt-length-doesnt-work-anymore ).

My fix in the end was Instead of using the_excerpt if there isn’t a more tag, I’m doing a custom function to get a content at an arbitrary length.

I’m using a child theme of twenty eleven, hence the $content .= twentyeleven_continue_reading_link(); at the end.

in my showcase.php

// Set $more to 0 in order to only get the first part of the post.
						global $more;
						$more = 0;

						if ( has_post_format()) {
                            get_template_part( 'content', get_post_format() );
                        } else {
                            get_template_part( 'content', 'index' );
						}

In my content-index.php

<?php if (has_more()) {
		        the_content( __( 'Continue reading <span class="meta-nav">→</span>', 'twentyeleven' ) );
		    } else {
                $my_content = limit_content();
                //$my_content = apply_filters('the_content', $my_content);
                //$my_content = str_replace(']]>', ']]>', $my_content);
                echo $my_content;
            }?>

in the functions.php

//more tag detection
//http://wordpress.org/support/topic/check-if-post-has-more
function has_more()
{
 global $post;
 if ( empty( $post ) ) return;

    if ($pos=strpos($post->post_content, '<!--more-->')) {
        return true;
    } else {
        return false;
    }
}

function more_posistion()
{
    if ($pos=strpos($post->post_content, '<!--more-->')) {
        return $pos;
    }
}

//limit content length
//http://www.fusedthought.com/archives/wordpress-custom-content-length-code-snippet
function limit_content($content_length = 150, $allowtags = true, $allowedtags = '') {
	global $post;
	$content = $post->post_content;
	$content = apply_filters('the_content', $content);
	if (!$allowtags){
		$allowedtags .= '<style>';
		$content = strip_tags($content, $allowedtags);
	}
	$content = str_replace(']]>', ']]>', $content);
	$wordarray = explode(' ', $content, $content_length + 1);
	if(count($wordarray) > $content_length) :
		array_pop($wordarray);
		//array_push($wordarray, '...');
		$content = implode(' ', $wordarray);
		$content .= "</p>";
		$content .= twentyeleven_continue_reading_link();
	endif;

	echo $content;
}

I’m sorry, but I am also having this trouble.

Using a twenty eleven child them, Ive added the following to my functions.php to no avail.

remove_filter( 'excerpt_length', 'twentyeleven_excerpt_length' );
function new_excerpt_length($length) {
	return 10;
}
add_filter('excerpt_length', 'new_excerpt_length');

The Excerpt Length Plugin doesn’t work.

using the get_the_excerpt call in my content.php template instead doesn’t work.

the example code in this support doesn’t work for me:

The example code from the support topic below does – but it seems like the nuclear option:
http://wordpress.org/support/topic/changing-the-default-length-of-the_excerpt-1

Any thoughts?
