get_the_content() must be inside the loop, in header.php you can do this (don’t forget to scape the content to use it as attribute): if (is_single()) { while (have_posts()) { the_post(); $content = get_the_content(); $desc=”<meta property=”og:description” content=””. esc_attr($content) .'”>’; echo $desc; } } or even better, in your functions.php hook the wp_head action; also, I recomend … Read more
You want to add a filter to the filter queue on the_content: add_filter(‘the_content’, ‘anything’); WordPress core then calls apply_filters within the_content function to run all filters in the queue: function the_content( $more_link_text = null, $strip_teaser = false) { $content = get_the_content( $more_link_text, $strip_teaser ); $content = apply_filters( ‘the_content’, $content ); $content = str_replace( ‘]]>’, ‘]]>’, … Read more
The above answer (“So it turns out”) turns out not to be the answer after all. With the fix described there, comments that I submitted were rendered correctly but comments that others submitted were not (even though I was submitting through the same comment interface that everyone else was).

I had installed the “Facebook Comments for WordPress” plugin. This plugin attaches a filter to the_content();. The filter contains the line wp_reset_query();. Commenting this out fixes the problem (this is sub-optimal though, because, now the client will be unable to update the plugin).
By default WordPress cannot search in template content. You should import your content into the data base. The plugin HTML Import 2 will help here. Another option is a separate search engine with a parser that can read the complete HTML output. The plugin Search Unleashed for example supports Apache Lucene. That’s probably too much … Read more
First, I wouldn’t modify the string/word length of the content. Semantically, you’re dealing with an excerpt, so let’s focus on that. Second, to limit the number of words returned for the excerpt, simply filter excerpt_length: <?php function wpse52673_filter_excerpt_length( $length ) { // Return (integer) value for // word-length of excerpt return 150; } add_filter( ‘excerpt_length’, … Read more
