Meta Box doesn't appear

时间：2016-04-30 作者：Erdinç Taze

我有3个自定义帖子类型和3个元框文件。问题是我在functions.php. 对于每个自定义帖子类型，我有三个元框PHP文件，但它只显示了最近添加的自定义帖子的一个元框字段。示例：

功能。php：

include \'inc/referanslar.php\';
include \'inc/hizmetler/hizmetler.php\';
include \'inc/projeler.php\',
include \'inc/projeler-meta-box.php\',
include \'inc/hizmetler/hizmetler-meta-box.php\';
include \'inc/referanslar-meta-box.php\';
它只是显示referanslar-meta-box.php 因为它在所有文件下。以下是我的元框文件：

如果不添加自定义帖子类型，第二个帖子的函数调用似乎有误

add_action(\'admin_menu\', \'mytheme_add_box\'); 
// Add meta box
function referans_add_box() {
你想说什么

add_action(\'admin_menu\', \'referans_add_box\'); 
// Add meta box
function referans_add_box() {
