当我尝试在两种不同的分类法中添加新帖子时，我收到了一条通知，其中一种我使用自定义元框，另一种则不使用，但是当我尝试添加新项目时，这两种分类法都会出现通知，我看到：通知：未定义索引：product\\u noncename in/Applications/MAMP/htdocs/site/wordpress/wp-content/themes/theme/functions。第259行中的php隐藏在WP Admin中顶部黑色条带的略下方
Line 259 is:
if ( !wp_verify_nonce( $_POST[\'product_noncename\'], plugin_basename(__FILE__) )) {
which is part of this:
// Save the Metabox Data
function wpt_save_product_meta($post_id, $post) {
// verify this came from the our screen and with proper authorization,
// because save_post can be triggered at other times

return $post->ID;
}
// Is the user allowed to edit the post or page?
if ( !current_user_can( \'edit_post\', $post->ID ))
return $post->ID;
// OK, we\'re authenticated: we need to find and save the data
// We\'ll put it into an array to make it easier to loop though.

if( $post->post_type == \'revision\' ) return; // Don\'t store custom data twice
$value = implode(\',\', (array)$value); // If $value is an array, make it a CSV (unlikely)

if(!$value) delete_post_meta($post->ID, $key); // Delete if blank
}
}
add_action(\'save_post\', \'wpt_save_product_meta\', 1, 2); // save the custom fields
