未捕获错误：调用中的未定义函数wp_get_Current_User()

时间：2019-12-30 作者：Faruk rıza

我的简单插件出现错误：

   // Class wpb_widget ends here
    add_action(\'init\',\'do_stuff\');
    function TopAuthor() {
        $contributor_ids = get_users( array(
            \'fields\'  => \'ID\',
            \'orderby\' => \'post_count\',
            \'order\'   => \'DESC\',
            \'who\'     => \'authors\',
        ) );

        foreach ( $contributor_ids as $contributor_id ) :
            $post_count = count_user_posts( $contributor_id );

            // Move on if user has not published a post (yet).
            if ( ! $post_count ) {
                continue;

你必须打电话TopAuthor() 中的函数plugins_loaded 或init 行动您正在Fatal error: Uncaught Error: Call to undefined function wp_get_current_user() 因为wp_get_current_user() 是一个可插入的函数。包含插件时不能调用。你必须等待行动plugins_loaded 或init. 致电您的TopAuthor() 函数使用init 或plugins_loaded 行动

init action:

add_action(\'init\',\'do_stuff\');

plugins_loaded action:

add_action(\'plugins_loaded\',\'do_stuff\');

Your function :

function do_stuff()
{
    TopAuthor();
}

So full code of Your Plugin file look like:
