WordPress插件Required_Once文件-无法使用WordPress函数

时间：2016-06-01 作者：cgee

我读了很多关于require_once 在stackoverflow中。

但没有人能解决我的问题。

我有一个带有两个文件的插件。

dmd_main.php //main file

dmd_second.php //some WP functions
在我的主文件中，我包含了这一行：

require_once (plugin_dir_path(__FILE__) . \'includes/dmd_second.php\');
但在我的第二个文件中，我仍然收到了错误信息：

调用未定义的函数get\\u option（）

我听说这是使用wordpress函数的正确方法，还是不正确？

我已经尝试了很多，如果我将其包含在第二个文件中，此代码将起作用：

include_once($_SERVER[\'DOCUMENT_ROOT\'].\'wp-config.php\' );
但这个解决方案真的很糟糕。

有人能解释一下我如何解决这个问题吗？

编辑：

主文件中的代码：

我不确定您是否试图在实际WordPress应用程序之外使用WordPress功能，但要实现这一点，您只需执行以下操作：

require( \'path-to-wordpress/wp-load.php\' );

如果WordPress应用程序的路径实际上是$_SERVER[\'DOCUMENT_ROOT\'] 那你会的

require ( $_SERVER[\'DOCUMENT_ROOT\'] . \'/wp-load.php\' );

插件已经安装并激活，并且执行了PHP代码，这并不意味着它突然成为WordPress的一部分。您应该让您的插件在WordPress挂钩上初始化，这意味着在WordPress达到执行过程中的某个阶段之前，代码不会被执行。

实际上你已经做了很多这样的钩子了，干得好！。

尝试替换dmd\\U main中的最后一行。php发件人$a = new dmd_pages();到

add_action( \'init\', \'wpse_228476_dmd_init\' );
function wpse_228476_dmd_init() {
    $a = new dmd_pages();
}
