我创建了一个自定义元框，并将其粘贴到函数中。php（减去<?php 当然可以打电话）

我在这个元框中有两个字段，一个标记为“主要标题”，另一个标记为“次要标题”。

如何分别调用这些框中的数据，以便将它们插入到页面模板中？

<?php
$prefix = \'dbt_\';
$meta_box = array(
  \'id\' => \'my-meta-box\',
  \'title\' => \'Custom meta box\',
  \'page\' => \'post\',
  \'context\' => \'normal\',
  \'priority\' => \'high\',
  \'fields\' => array(
    array(
     \'name\' => \'Primary Title\',
     \'id\' => $prefix . \'text\',
     \'type\' => \'text\'
    ),
    array(
     \'name\' => \'Secondary Title\',
     \'id\' => $prefix . \'text1\',
     \'type\' => \'text\',  
    )   
  )
);

add_action(\'admin_menu\', \'mytheme_add_box\');

// Add meta box
function mytheme_add_box() {
  global $meta_box;
  add_meta_box(
    $meta_box[\'id\'],
    $meta_box[\'title\'],
    \'mytheme_show_box\',
    $meta_box[\'page\'],
    $meta_box[\'context\'],
    $meta_box[\'priority\']
  );
}

// Callback function to show fields in meta box
function mytheme_show_box() {
  global $meta_box, $post;
  // Use nonce for verification
  echo \'<input type="hidden" name="mytheme_meta_box_nonce" value="\';
  echo wp_create_nonce(basename(__FILE__)), \'" />\';
  echo \'<table class="form-table">\';
  foreach ($meta_box[\'fields\'] as $field) {
    // get current post meta data
    $meta = get_post_meta($post->ID, $field[\'id\'], true);   
    echo \'<tr><th style="width:20%"><label for="\' . $field[\'id\'] . \'">\';
    echo $field[\'name\'];
    echo \'</label></th><td>\';
    switch ($field[\'type\']) {
      case \'text\':
        echo \'<input type="text" name="\' . $field[\'id\'] . \'"\';
        echo \' id="\' .$field[\'id\'] . \'"\';
        echo \' value="\' . ( $meta ? $meta : $field[\'std\'] ) . \'"\';
        echo \' size="30" style="width:97%" />\';
        echo \'<br />\' . $field[\'desc\'];
        break;
    }
    echo \'<td></tr>\';
  }
  echo \'</table>\';
}

add_action(\'save_post\', \'mytheme_save_data\');

// Save data from meta box
function mytheme_save_data($post_id) {
    global $meta_box;
    // verify nonce
    if (!wp_verify_nonce($_POST[\'mytheme_meta_box_nonce\'], basename(__FILE__))) {
      return $post_id;
    }
    // check autosave
    if (defined(\'DOING_AUTOSAVE\') && DOING_AUTOSAVE) {
      return $post_id;
    }
    // check permissions
    if (\'page\' == $_POST[\'post_type\']) {
      if (!current_user_can(\'edit_page\', $post_id)) {
        return $post_id;
      }
    } elseif (!current_user_can(\'edit_post\', $post_id)) {
      return $post_id;
    }
    foreach ($meta_box[\'fields\'] as $field) {
      $old = get_post_meta($post_id, $field[\'id\'], true);
      $new = $_POST[$field[\'id\']];  
      if ($new && $new != $old) {
        update_post_meta($post_id, $field[\'id\'], $new);
      } elseif ( \'\' == $new && $old ) {
        delete_post_meta($post_id, $field[\'id\'], $old);
      }
    }
}
?>
