Shortcode
-
I need a shortcode for this plugin and found that it didn’t exist. Here’s my stab at it, perhaps someone can improve upon my code, but at least it’s a good first effort (as far as I can tell, it’s working on my site.) Open to feedback…I’m not the developer, just a user.
I’ve added a fallback for posts without a category and/or without a category image, to use category ID 1 (uncategorized) – certain sites might need to change this value to something else.
// CREATE SHORTCODE FOR "CATEGORIES IMAGES" OUTPUT add_shortcode( 'category-image', 'categories_images' ); function categories_images() { $category = get_the_terms( $id, 'category' ); $categoryid = $category[0]->term_id; $taxonomy_image_url = get_option('z_taxonomy_image'.$categoryid); if(empty($taxonomy_image_url)) { // If no category, or if category doesn't have an image, use the image for "Uncategorized" $categoryid = 1; $taxonomy_image_url = get_option('z_taxonomy_image'.$categoryid); } if(!empty($taxonomy_image_url)) { $attachment_id = z_get_attachment_id_by_url($taxonomy_image_url); if(!empty($attachment_id)) $category_image = wp_get_attachment_image($attachment_id, $size, FALSE, $attr); else { $image_attr = ''; if(is_array($attr)) { if(!empty($attr['class'])) $image_attr .= ' class="'.$attr['class'].'" '; if(!empty($attr['alt'])) $image_attr .= ' alt="'.$attr['alt'].'" '; if(!empty($attr['width'])) $image_attr .= ' width="'.$attr['width'].'" '; if(!empty($attr['height'])) $image_attr .= ' height="'.$attr['height'].'" '; if(!empty($attr['title'])) $image_attr .= ' title="'.$attr['title'].'" '; } $category_image = '<img src="'.$taxonomy_image_url.'" '.$image_attr.'/>'; } } return $category_image; }
