   Hello

   I am wanting to display meta data on my WP site...

   I am using a write panel that I have started using a great tutorial I found... my functions file has the following code:

   /*
   Plugin Name: Custom Write Panel
   Plugin URI: http://wefunction.com/2008/10/tutorial-create-custom-write-panels-in-wordpress
   Description: Allows custom fields to be added to the WordPress Post Page
   Version: 1.0

   Author URI: http://wefunction.com
   /* ----------------------------------------------*/
   
   $new_meta_boxes =
     array(
   	  "image" => array(
   	  "name" => "image",
   	  "std" => "",
   	  "title" => "Product Image",
   	  "description" => "Enter full path to image here."
   	  ),
   	  "price" => array(
   	  "name" => "price",
   	  "std" => "",
   	  "title" => "Product Price",
   	  "description" => "Only numbers and periods!  DO NOT ENTER \"$\"!"
   	  ),
   	  "size" => array(
   	  "name" => "sizes",
   	  "std" => "",
   	  "title" => "Available Sizes",
   	  "description" => "Enter comma-separated values. (ex: \"Small, Medium, Large\")"
   	  ),
   	  "colors" => array(
   	  "name" => "colors",
   	  "std" => "",
   	  "title" => "Available Colors",
   	  "description" => "Enter comma-separated values. (ex: \"Red, White, Blue\")"
   	  ),
   	  "catalog" => array(
   	  "name" => "catalog",
   	  "std" => "",
   	  "title" => "Catalog Number",
   	  "description" => "Enter catalog number here."
   	  ),
   	  "cannotbuy" => array(
   	  "name" => "cannotbuy",
   	  "std" => "",
   	  "title" => "Cannot Purchase Online",
   	  "description" => "If this is an item that is not allowed to be sold online, type in \"yes\" or \"y\"."
   	  ),
   	  "sale" => array(
   	  "name" => "sale",
   	  "std" => "",
   	  "title" => "Sale Price",
   	  "description" => "Enter in a dollar amount or percentage off - be sure to include the \"$\" or \"%\" symbols."
   	  ),
   	  "quantity" => array(
   	  "name" => "quantity",
   	  "std" => "",
   	  "title" => "Quantity in Stock",
   	  "description" => "Enter in a value for how many items you have in stock."
   	  )
     );
   
   function new_meta_boxes() {
   global $post, $new_meta_boxes;
   
   foreach($new_meta_boxes as $meta_box) {
   $meta_box_value = get_post_meta($post->ID, $meta_box['name'].'_value', true);
   
   if($meta_box_value == "")
   $meta_box_value = $meta_box['std'];
   
   echo'<input type="hidden" name="'.$meta_box['name'].'_noncename" id="'.$meta_box['name'].'_noncename" value="'.wp_create_nonce( plugin_basename(__FILE__) ).'" />';
   
   echo'<h2>'.$meta_box['title'].'</h2>';
   
   echo'<input type="text" name="'.$meta_box['name'].'_value" value="'.$meta_box_value.'" size="55" /><br />';
   
   echo'<p><label for="'.$meta_box['name'].'_value">'.$meta_box['description'].'</label></p>';
   }
   }
   
   function create_meta_box() {
   global $theme_name;
   if ( function_exists('add_meta_box') ) {
   add_meta_box( 'new-meta-boxes', 'Course Information', 'new_meta_boxes', 'post', 'normal', 'high' );
   }
   }
   
   function save_postdata( $post_id ) {
   global $post, $new_meta_boxes;
   
   foreach($new_meta_boxes as $meta_box) {
   // Verify
   if ( !wp_verify_nonce( $_POST[$meta_box['name'].'_noncename'], plugin_basename(__FILE__) )) {
   return $post_id;
   }
   
   if ( 'page' == $_POST['post_type'] ) {
   if ( !current_user_can( 'edit_page', $post_id ))
   return $post_id;
   } else {
   if ( !current_user_can( 'edit_post', $post_id ))
   return $post_id;
   }
   
   $data = $_POST[$meta_box['name'].'_value'];
   
   if(get_post_meta($post_id, $meta_box['name'].'_value') == "")
   add_post_meta($post_id, $meta_box['name'].'_value', $data, true);
   elseif($data != get_post_meta($post_id, $meta_box['name'].'_value', true))
   update_post_meta($post_id, $meta_box['name'].'_value', $data);
   elseif($data == "")
   delete_post_meta($post_id, $meta_box['name'].'_value', get_post_meta($post_id, $meta_box['name'].'_value', true));
   }
   }
   
   add_action('admin_menu', 'create_meta_box');
   add_action('save_post', 'save_postdata');
   
   ?>

   My problem is that the meta - displayed using : <?php the_meta(); ?> in single.php displays the data thusly:

   price_value: 4

   Where I want it to read

   Price: 4

   As seen on the site im making: here

   Any help appreciated!

   Dave

   <?php
   $price = get_post_meta($post->ID, 'price_value', true);
   if ($price){
   echo 'Price: '.$price;
   }
   ?>

   See: Custom_Fields

   Cheers again MichaelH~!

   That works brilliantly!

   I have been doing some reading regarding custom fields. I still cant work out how to now add to display other values such as 'sizes_value' without using the above code in its entirety and changing 'prices' to' sizes'

   Thanks

   Dave

   Or use Function_Reference/get_post_custom and use an if to display only display the fields you want.
