I'm in designing a WP Theme. I need help! I'm calling category and it's slug from plugin functions. Here is the code:
$category = get_the_category();
$html .= '<div id="category-post" class="category-main category'. $category[0]->slug .'">';
$html .= $category[0]->cat_name;
$html .= '</div>';
Let's say I have a class name for health category: .category-health
but the above code will returned to: <div id="category-post" class="category-main categoryhealth"></div>
and the class: .category-health not working because it returned to unavailable category: .categoryhealth
From above code I feel that the category slug " - " is not working. Because the right class is ".category-health" and not ".categoryhealth"
Is there any way to fix this? Thanks
