I too want to know this. I like the plugin but the customization is broken, I don’t want the : separating the title and excerpt so the only way to do it is to choose a custom pattern_form, but that strips most of the tags making them difficult to customize.
Unfortunately darkwarriorblake if you want to be able to do this you’ll have to edit the plugin, which means you will have problems updating. Hopefully the plugin author will continue to develop the plugin as it works really well apart from this problem and the problem of displaying most popular posts in the current category.
Hopefully this code will help you add category ids as classes to your lis:
$cid = get_the_category($p->id);
$cidfull = "cat-item cat-item-" . $cid[0]->cat_ID;
$data = array(
'title' => '<a data-cat="' . $cid[0]->cat_ID . '" href="' . $permalink . '" title="' . $title . '">' . $title_sub . '</a>',
'summary' => $excerpt,
'stats' => $stats,
'img' => $thumb,
'id' => $p->id,
'category' => $cidfull
);
array_push($posts_data, $data);
// PUTTING IT ALL TOGETHER
if ($instance['markup']['custom_html']) { // build custom layout
$classes = "";
foreach ($cid as $c) {
$classes.="cat-item-".$c->cat_ID." ";
}
if ($instance['markup']['list']) {
if ($instance['markup']['pattern']['active']) {
$content .= "<li class=\"cat-item-list $classes cat-post-" . $p->id ."\" data-postid=\"".$p->id."\" data-cat=\"" . $cid[0]->cat_ID . "\">" . htmlspecialchars_decode($this->format_content($instance['markup']['pattern']['form'], $data, $instance['rating'])) . htmlspecialchars_decode($instance['markup']['post-end'], ENT_QUOTES) . "\n";
} else {
$content .= "<li class=\"cat-item-list $classes cat-post-" . $p->id ."\" data-postid=\"".$p->id."\" data-cat=\"" . $cid[0]->cat_ID . "\">" . "{$thumb}<a href=\"{$permalink}\" title=\"{$title}\" class=\"wpp-post-title\">{$title_sub}</a> {$excerpt}{$stats}{$rating}" . htmlspecialchars_decode($instance['markup']['post-end'], ENT_QUOTES) . "\n";
}
} else {
if ($instance['markup']['pattern']['active']) {
$content .= "<li class=\"cat-item $classes cat-post-" . $p->id ."\" data-postid=\"".$p->id."\" data-cat=\"" . $cid[0]->cat_ID . "\">" . htmlspecialchars_decode($this->format_content($instance['markup']['pattern']['form'], $data, $instance['rating'])) . htmlspecialchars_decode($instance['markup']['post-end'], ENT_QUOTES) . "\n";
} else {
$content .= "<li class=\"cat-item $classes cat-post-" . $p->id ."\" data-postid=\"".$p->id."\" data-cat=\"" . $cid[0]->cat_ID . "\">" . "{$thumb}<a href=\"{$permalink}\" title=\"{$title}\" class=\"wpp-post-title\">{$title_sub}</a> {$excerpt}{$stats}{$rating}" . htmlspecialchars_decode($instance['markup']['post-end'], ENT_QUOTES) . "\n";
}
}
} else { // build regular layout
$content .= "<li class=\"cat-item cat-item-" . $cid[0]->cat_ID . "\" data-cat=\"" . $cid[0]->cat_ID . "\">{$thumb}<a href=\"{$permalink}\" title=\"{$title}\" class=\"wpp-post-title\">{$title_sub}</a> {$excerpt}<span class=\"post-stats\">{$stats}</span>{$rating}</li>" . "\n";
}
}
