I have been scouring the net for some ideas, and banging out some code, but have come up to a wall trying to figure this one out.
And starting to think this is beyond WP's functionality!
I want users to be able to specify a manual excerpt in the post editor, and allow them to include html tags such as an image, and link.
So far, I have been able to set automatic excerpts to allow for html tags through this
// ALLOW html tags in excerpts
function improved_trim_excerpt($text) {
global $post;
if ( '' == $text ) {
$text = get_the_content('');
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
$text = preg_replace('@<script[^>]*?>.*?</script>@si', '', $text);
$text = strip_tags($text, '<img><span><a>');
$excerpt_length = 90;
$words = explode(' ', $text, $excerpt_length + 5);
if (count($words)> $excerpt_length) {
array_pop($words);
array_push($words, '[...]');
$text = implode(' ', $words);
}
}
return $text;
}
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'improved_trim_excerpt');But for manual excerpt customizing, I can only seem to allow an add a "read more" link text through this
add_filter('get_the_excerpt', 'manual_excerpt_more');
function manual_excerpt_more($excerpt) {
$excerpt_more = '';
if( has_excerpt() ) {
$excerpt_more = ' <a href="'.get_permalink().'" rel="nofollow">...continue reading</a>';
$excerpt_more = strip_tags($excerpt_more, '<img><span><a>');
}
return $excerpt . $excerpt_more;
}As you can see I tried to add in html tags with $excerpt_more = strip_tags($excerpt_more, '<p><img><span><a>'); but this does not seem to work.
Anyone have suggestions?
