Post Titles By Category

This code will list post titles, with links to the full posts, by category name.

It does not provide pagination, so the page could get quite long.  On a large site, the number of queries could cause timeouts or server overload.

It is not complete by itself as it needs to be integrated with your theme by putting in the appropriate get_header(), divs, get_sidebar(), etc.

Custom Excerpt to Handle Broken HTML

If you want to retain some HTML tags in your excerpts, you can’t just select the text from the content of the file.  Usually this will cause some HTML tags to be ‘broken’ because the ending tag is not included in the selected text.

Here is a function to be added to your functions.php file which will correct the HTML.

//custom excerpt
function custom_excerpt($num,$p = true,$echo=true) {
// $num is the number of 'words', space separated, to excerpt
// $p will enclose the excerpt in p tags if true
// $echo will echo the excerpt if true, return it if false
$theexcerpt = get_the_content();
$new_theexcerpt = explode(' ', $theexcerpt, $num);
$new_theexcerpt = implode(' ', $new_theexcerpt);
$new_theexcerpt .= '...';
libxml_use_internal_errors(true); //use this to prevent warning messages from displaying because of the bad HTML
$doc = new DOMDocument();
$goodHtml = $doc->saveHTML();
$cleanHtml = trim(ereg_replace('(.*)<body>(.*)</body>(.*)', '\2', $goodHtml));

if($p==true) { $cleanHtml = '<p>' . $cleanHtml . '</p>'; };
if ($echo != true) return $cleanHtml;
echo $cleanHtml;
