Apparently, there’s no way. UPDATE! Joost De Valk, the author of WordPress SEO by Yoast, modified how the plugin works on my request in the plugin’s support forums. So, problem solved!
You use preg_replace function incorrectly. This function returns replaced content: add_filter( ‘the_content’, ‘wpdu_image_replace’ ); function wpdu_image_replace( $content ) { return preg_replace( ‘/<img.*?src=”https://wordpress.stackexchange.com/questions/55241/(.*?)”.*?>/’, ‘<a href=”$1″>Image file</a>’, $content ); } Also pay attention that you don’t have to use global variable $post, because content of the post is passed to your function as first argument.
replace the_content(); with echo wpse_limit_content(); function wpse_limit_content() { $content = $post->post_content; $MAX_LENGTH = 100; if ( strlen( $content ) <= $MAX_LENGTH ) return apply_filters(‘the_content’, $content ); $s2 = substr( $content, 0, $MAX_LENGTH ); $s3 = preg_split( “/\s+(?=\S*+$)/”, $s2 ); $s4 = $s3[0]; return apply_filters( ‘the_excerpt’, $s4 ); } If the string is to long it … Read more
where are you setting $ecpt_challenge, $ecpt_solution and $ecpt_results? also get_post_meta($post->ID, ‘ecpt_goal’, false); returns an array, so use print_r ( get_post_meta($post->ID, ‘ecpt_goal’, false)); OR for single result pass “true” in the last argument. echo get_post_meta($post->ID, ‘ecpt_goal’, true); reference: get_post_meta() @codex

The pre_get_posts action hook only allows you to modify the $query object . Any formatting or output of data is done in the template file within the loop. When you are in the loop you have access to various template tags that output the post data formatted (filters applied). if ( have_posts() ) : while … Read more
You could add a link manually like: <a href=”https://wordpress.stackexchange.com/questions/88976/<?php echo get_permalink($post->ID) ?>”>Read More…</a> If you want to add the link at the end of the content you could do: return implode(‘ ‘, array_slice($words, 0, $word_limit)) . ‘<a href=”‘.get_permalink($post->ID).'”>Read More…</a>’;
the_content does echo the content. That is stated in the Codex– “Displays the contents of the current post”, emphasis mine. Use get_the_content instead, to return a string that you can manipulate. Be aware that get_the_content does not run all of the same filter as the_content. Again from the Codex: If you use plugins that filter … Read more
Use get_permalink. Otherwise this is basically a PHP string concatenation question. the_content(‘<a href=”‘.get_permalink().'” class=”button”>Read More</a>’);
WordPress creates 3 different sizes as far as my research goes.
