The function register_post_type() accepts two arguments: the name we want to give our post type, and a list of arguments used to create that post type, which we put in an array called $args.

Using above code that code will add the product post type to wordpress panel.

Now you can add the meta fields to custom post type. Use the following code in file for add the meta fields. Custom meta fields function is available from quite some time. add_meta_box() function is very useful to adding custom fields to wordpress post.

01<?php
02 
03 add_action("admin_init", "add_product");
04 add_action('save_post', 'update_thumbnail_url');
05 function add_product(){
06 add_meta_box("product_details", "product Options", "product_options", "product", "normal", "low");
07 }
08 function product_options(){
09 global $post;
10 $custom = get_post_custom($post->ID);
11 $thumbnail_url = $custom["thumbnail_url"][0];
12 $product_info = $custom["product_info"][0];
13 $product_infos = $custom["product_infos"][0];
14 $video_code = $custom["video_code"][0];
15 
16?>
17 <div id="product-options">
18 <label>Thumbnail URL:</label><input size="100" name="thumbnail_url" value="<?php echo $thumbnail_url; ?>" /><br>
19 <label>Product Info:</label><input size="100" name="product_info" value="<?php echo $product_info; ?>" /><br>
20 <img src="<?php echo $product_infos; ?>"><br>
21 <label>Video Code:</label><textarea cols="50" rows="5" name="video_code"><?php $video_code; ?></textarea>
22 </div><!--end product-options-->
23<?php
24 }
25 function update_thumbnail_url(){
26 global $post;
27 update_post_meta($post->ID, "thumbnail_url", $_POST["thumbnail_url"]);
28 update_post_meta($post->ID, "product_info", $_POST["product_info"]);

05function product_edit_columns($columns){
06 $columns = array(
07 "cb" => "<input type=\"checkbox\" />",
08 "title" => "Product Title",
09 "thumbnail_url" => "Thumbnail URL",
10 "product_info" => "Product Info",

12 );
13 return $columns;
14}
15function product_custom_columns($column){
16 global $post;
17 switch ($column) {
18 case "thumbnail_url":
19 $custom = get_post_custom();
20 echo $custom["thumbnail_url"][0];
21 break;
22 case "product_info":
23 $custom = get_post_custom();
24 echo $custom["product_info"][0];
25 break;
26 case "video_code":
27 $custom = get_post_custom();
28 echo $custom["video_code"][0];
29 break;
30 }
31}
32 
33?>

Using custom post type and add meta tag you can develop very nice applications. Now I am going to show you how you can extract the custom posts in wordpress frontend.

Using wp_query you can easily extract product posts. In any category page or conditionally you can use following code.

01$loop = new WP_Query( array( 'post_type' => 'product', 'posts_per_page' => 10 ) );
02while ( $loop->have_posts() ) : $loop->the_post();
03 the_title();
04the_content();
05global $post;
06 $custom = get_post_custom($post->ID);
07echo $thumbnail_url = $custom["thumbnail_url"][0];
08echo $product_info = $custom["product_info"][0];
09echo $video_code = $custom["video_code"][0];
10 echo '<div>';
11 the_content();
12 echo '</div>';
13endwhile;

Or you can create the custom theme page using following code. Just create product.php page in your wordpress theme folder.Put following code in that file.

01<?php
02 
03/*Template Name: Product*/
04 
05?>
06 
07<?php get_header(); ?>
08 
09<div id="container">
10 
11<div id="content" role="main">
12 
13<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>
14 
15<?php $recent = new WP_Query('post_type=product&posts_per_page=10′); while($recent->have_posts()) : $recent->the_post();?>
16 
17<?php the_title( '<h2><a href="' . get_permalink() . '" title="' . the_title_attribute( 'echo=0′ ) . '" rel="bookmark">', '</a></h2>' ); ?>
18 
19<div>
20 
21<?php the_content(); ?>
22 
23<?php
24 
25the_content();
26global $post;
27$custom = get_post_custom($post->ID);
28echo $thumbnail_url = $custom["thumbnail_url"][0];
29echo $product_info = $custom["product_info"][0];
30echo $video_code = $custom["video_code"][0];
31 
32?>
33 
34<?php wp_link_pages( array( 'before' => '<div>' . __( 'Pages:', 'wordpressapi' ), 'after' => '</div>' ) ); ?>
35 
36<?php edit_post_link( __( 'Edit', 'wordpressapi' ), '<span>', '</span>' ); ?>
37 
38</div><!– .entry-content –>
39 
40<?php comments_template( ", true ); ?>
41 
42<?php endwhile; ?>
43 
44</div><!– #content –>
45 
46</div><!– #container –>
47 
48<?php get_sidebar(); ?>
49 
50<?php get_footer(); ?>

Now create product page and product as template.
