I am creating a Wordpress website for a travel agent that offers special offers in different places and displays them on one page. So, I used the following code to allow filtering of the custom message type that I configured, with the display of individual excerpts and images.
Here is what I have:
<code> <?php get_header(); ?> <div id="content" class="two_third <?php echo of_get_option('blog_sidebar_pos') ?>"> <div id="sort"> <h5>SORT BY : </h5> <ul> <li><a href="<?php echo add_query_arg(array ('paged' => '1', 'orderby' => 'date', 'order' => 'DESC'));?>">Date</a></li> <li><a href="<?php echo add_query_arg(array ('paged' => '1', 'orderby' => 'title', 'order' => 'ASC'));?>">Deal (A to Z)</a></li> <li><a href="<?php echo add_query_arg(array ('paged' => '1', 'orderby' => 'meta_value', 'order' => 'ASC', 'meta_key' => 'price'));?>">price (A to Z)</a></li> </ul> </div> <div id="filter"> <h5>FILTER BY : </h5> <ul> <?php $categories= get_categories('taxonomy=types&title_li='); foreach ($categories as $category){ ?> <li><a href="<?php echo add_query_arg(array ('paged' => '1', 'filter' => $category->category_nicename));?>" title="Filter by <?php echo $category->name;?>"><?php echo $category->name;?></a></li> <?php }?> </ul> </div> <div id="reset-filters"> <a href="<?php echo add_query_arg(array ('paged' => '1', 'filter' => ''));?>">reset filters</a> </div> <div id="gallery" class="one_column"> <ul class="portfolio"> <?php $query = 'post_type=gs_deals&types='.$_GET['filter'].'&orderby='.$_GET['orderby'].'&order='.$_GET['order'].'&meta_key='.$_GET['meta_key'].'&posts_per_page=3&paged='.$paged; query_posts($query); if (have_posts()) : while (have_posts()) : the_post(); $custom = get_post_custom(get_the_ID()); ?> <?php $categories= get_categories('taxonomy=types&title_li='); foreach ($categories as $category){ ?> <div id="category"><h3><?php echo $category->name;?></h3> <?php }?> <li class="clearfix"> <div class="clearfix"> <span class="image-border"><a class="image-wrap" href="<?php the_permalink() ?>" title="<?php _e('Permanent Link to', 'theme1512');?> <?php the_title_attribute(); ?>" ><?php the_post_thumbnail( 'portfolio-post-thumbnail-xl' ); ?></a></span> <div class="folio-desc"> <h6 class="project">Deal!</h6> <p><a href="<?php the_permalink(); ?>" rel="bookmark" title="<?php echo get_the_title(); ?>"><?php the_title(); ?></a></p> <h6 class="client">Price :</h6> <h4><?php echo $custom["price"][0];?></h4> <p class="short"><?php echo $custom["short_text"][0];?></p> <p><a href="<?php the_permalink(); ?>">View Details</a></p> </div> </div> </li> </div> <?php endwhile; ?> <?php endif;?> </ul> <div class="posts-nav"> <div class="prev"><?php next_posts_link(__('? Older Projects')) ?></div> <div class="next"><?php previous_posts_link(__('Newer Projects ?')) ?></div> </div> </div> </div> <?php get_sidebar(); ?> <?php get_footer(); ?> </code>
And here are my .php functions that handle this:
//////REGISTER A CUSTOM POST TYPE add_action('init', 'gs_deals_register');//Always use a shortname like "gs_" not to see any 404 errors function gs_deals_register(){ $args = array( 'label' => __('Deals List'), 'singular_label' => __('Deals'), 'public' => true, 'show_ui' => true, 'capability_type' => 'post', 'hierarchical' => false, 'rewrite' => array('slug' => 'deals'),//Use a slug like "work" or "project" that shouldnt be same with your page name 'supports' => array('title', 'editor', 'thumbnail')//Boxes will be showed in the panel ); register_post_type( 'gs_deals' , $args ); } //////ADD CUSTOM INPUTS (Client & Short_text) add_action("admin_init", "admin_init"); add_action('save_post', 'save_options'); function admin_init(){ add_meta_box("gs_dealsInfo-meta", "Deals Options", "meta_options", "gs_deals", "side", "low"); } function meta_options(){ global $post; $custom = get_post_custom($post->ID); $price = $custom["price"][0]; $short_text = $custom["short_text"][0]; ?> <p><label>Price:</label><br /><input name="price" value="<?php echo $price; ?>" /></p> <p><label>Short Text:</label><br /><textarea name="short_text"><?php echo $short_text; ?></textarea></p> <?php } function save_options(){ if ( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE ) return $post_id; global $post; update_post_meta($post->ID, "price", $_POST["price"]); update_post_meta($post->ID, "short_text", $_POST["short_text"]); } //////ADD TAXONOMY FOR FILTERING (Taxonomy name: types) register_taxonomy("types", array("gs_deals"), array("hierarchical" => true, "label" => "Types", "singular_label" => "Types", "rewrite" => true)); //////ADD HOOKS FOR PANEL VIEW add_filter("manage_edit-gs_deals_columns", "gs_deals_edit_columns"); add_action("manage_posts_custom_column", "gs_deals_custom_columns"); function gs_deals_edit_columns($columns){ $columns = array( "cb" => "<input type=\"checkbox\" />", "title" => "Deal Title", "short_text" => "Short Text", "price" => "Price", "types" => "Types", ); return $columns; } function gs_deals_custom_columns($column){ global $post; $custom = get_post_custom(); switch ($column) { case "short_text": echo $custom["short_text"][0]; break; case "price": echo $custom["price"][0]; break; case "types": echo get_the_term_list($post->ID, 'types', '', ', ',''); break; } }
I would like to display the category name above the relevant posts, but it doesn't seem to work. Any help would be appreciated.
