你能做到吗？绝对地您只需查询_wp_page_template 的元键值$post 反对，并相应地采取行动。也许是这样的：

// Globalize $post
global $post;
// Get the page template post meta
$page_template = get_post_meta( $post->ID, \'_wp_page_template\', true );
// If the current page uses our specific
// template, then output our post meta
if ( \'template-foobar.php\' == $page_template ) {
    // Put your specific custom post meta stuff here
}

虽然完全实现自定义post meta框稍微超出了您的问题范围，但基本答案保持不变。不过，我会尽力为你指出大致的方向。您将使用add_meta_box(), 在连接到的回调中调用add_meta_boxes-{hook}, 用于定义元盒的回调，以及用于验证/清理和保存自定义post meta的回调。

function wpse70958_add_meta_boxes( $post ) {

    // Get the page template post meta
    $page_template = get_post_meta( $post->ID, \'_wp_page_template\', true );
    // If the current page uses our specific
    // template, then output our custom metabox
    if ( \'template-foobar.php\' == $page_template ) {
        add_meta_box(
            \'wpse70958-custom-metabox\', // Metabox HTML ID attribute
            \'Special Post Meta\', // Metabox title
            \'wpse70598_page_template_metabox\', // callback name
            \'page\', // post type
            \'side\', // context (advanced, normal, or side)
            \'default\', // priority (high, core, default or low)
        );
    }
}
// Make sure to use "_" instead of "-"
add_action( \'add_meta_boxes_page\', \'wpse70958_add_meta_boxes\' );


function wpse70598_page_template_metabox() {
    // Define the meta box form fields here
}


function wpse70958_save_custom_post_meta() {
    // Sanitize/validate post meta here, before calling update_post_meta()
}
add_action( \'publish_page\', \'wpse70958_save_custom_post_meta\' );
add_action( \'draft_page\', \'wpse70958_save_custom_post_meta\' );
add_action( \'future_page\', \'wpse70958_save_custom_post_meta\' );
