I have a wordpress site for news, where i have to cut the text after certain amount of characters. It all works fine via substr(), but when there are less than x characters it goes crazy and generate a nonsence in the link of the next <li>.
This is the code:
echo '<li>', get_the_date( 'd.m.Y', $recent["ID"] ), ' <a href="' . get_permalink($recent["ID"]) . '" title="Look '.esc_attr($recent["post_title"]).'" >' . $recent["post_title"].'</a> </li> ';
$post_id = $recent["ID"];
$post_content = get_post($post_id);
$content = $post_content->post_content;
echo mb_substr(do_shortcode( $content ), 0, 200 , "utf-8");
echo "...<br> <br>";
echo "</div>";
In the $content is there any HTML? If so and that gets chopped off, it will make the next 'li' be invalid HTML, perhaps... Just found this, might be of help
