Question

我试图创建一个从tinyMCE工具栏启动的弹出窗口。

当我对弹出窗口的内容添加wp_enqueue_media()调用时，我会在跟踪中获得以下异常：

[28-May-2015 01:32:00 UTC] PHP Fatal error:  Call to undefined function wp_get_current_user() in /Applications/MAMP/htdocs/devblog/wp-includes/capabilities.php on line 1385

我的主插件文件有这个（相关代码）：

if (strpos($_SERVER['REQUEST_URI'], 'media-upload.php') && strpos($_SERVER['REQUEST_URI'], '&type=z_recipe') && !strpos($_SERVER['REQUEST_URI'], '&wrt='))
{
    ZipRecipes::zrdn_iframe_content($_POST, $_REQUEST);
    exit;
}

和zrdn_iframe_content生成一个普通的.php文件，其中只包含html和以下php：

<?php
// jQuery
wp_enqueue_script('jquery');
// This will enqueue the Media Uploader script
wp_enqueue_media();
?>

导致这种情况我做错了什么？

Answer 1

在WordPress加载了必要的文件之前，您需要将wp_enqueue_media()移动到不能运行的函数内部。这是函数的explained further in the WP Codex。

例如：

function load_custom_code() {
    wp_enqueue_media();
}
add_action( 'admin_enqueue_scripts', 'load_custom_code' );

wp_enqueue_media（）调用导致致命错误
