如何从所有自定义帖子元数据中求和

我有一个metabox，每个客户每月都有预算
该元框位于称为客户端的自定义帖子类型中。在该元数据库中，唯一输入的是数字。

我想得到所有客户的总数<有什么想法吗？

虽然我认为这是纯php。。以某种方式使用foreach-应@Fahd Murtaza的请求，我正在尝试添加我的metabox的部分。。。我正在使用炼金术作为基础来创建我的元盒，因此会添加一些部分。。希望这不会让人更加困惑。。

<?php
// structure of my metabox usign alchemy
$clients = new WPAlchemy_MetaBox(array
(
    \'id\' => \'_project_description\',
    \'title\' => __(\'Client Info Card\', \'sagive\'),
    \'template\' => get_stylesheet_directory() . \'/metaboxes/clients-meta.php\',
    \'types\' => array(\'portfolio\'),
    \'context\' => \'normal\',
    \'priority\' => \'high\',
    \'autosave\' => TRUE

));

。

// call for budget section in my meta box
<p>
<label><?php _e(\'Clients Budget:\', \'sagive\'); ?></label>
    <?php $mb->the_field(\'client_budget\'); ?>
    <input type="text" name="<?php $metabox->the_name(\'client_budget\'); ?>" value="<?php $metabox->the_value(\'client_budget\'); ?>"/>
</p>

其余的代码太长了，我认为与显示无关。。。如果我错了，请纠正我，并通过粘贴纸或明喻添加它。。

THIS IS HOW I QUERY THE POSTS...

<?php 
    query_posts(array( 
        \'post_type\' => \'portfolio\',
        \'showposts\' => 10 
    ) );                    
    $count_posts_portfolio = wp_count_posts( \'portfolio\' )->publish;
?>

// For other arguments look into @link http://codex.wordpress.org/Class_Reference/WP_Query $posts = new WP_Query( \'post_type\' => \'portfolio\' ,\'post_status\' => \'publish\' ); foreach ( $posts as $post ) { $result[ $post->ID ][\'post_data\'] = $post->ID; $result[ $post->ID ][\'meta_data\'] = get_post_custom( $post->ID ); } foreach( $result as $id => $data ) { // Do whatever you need to do with your meta data in here. print \'The title is: \'.$post->post_title; // See your post data: print_r( $data[\'post_data\'] ); // See your meta data: print_r( $data[\'meta_data\'] ); }

$args = array( \'numberposts\' => -1, // all the posts \'post_type\' => \'clients\' ); $clients = get_posts( $args ); $total = 0; foreach( $clients as $client ) { $single = get_post_meta( $client->ID, \'metakey_name_here\', true ); $total += $single; }
