Wordpress admin-ajax.php 400 加载失败

如何解决Wordpress admin-ajax.php 400 加载失败

我正在使用 GitHub 上的此脚本“wordpress CPT Ajax 过滤”。

除了“全部”过滤器之外，一切正常，我需要它，单击此按钮，所有帖子消失，我收到以下错误，但其他猫过滤器有效。

XHR 加载失败：POST "**/wp-admin/admin-ajax.PHP"。发送@jquery.min.js:2

有人遇到过同样的事情或知道如何让它工作吗？

解决方法

我认为您在此处获取 ajax URL 的方式是错误的：https://www.sciencedirect.com/science/article/pii/S0950705120306195。

使用两个选项中的一个。

选项 1

在您的标题中添加：

<script type="text/javascript">
    var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>";
</script>

现在在您的 ajax 请求中使用这个 ajaxurl。

选项 2

使用脚本本地化。

wp_localize_script( 'FrontEndAjax','ajax',array(
    'url' => admin_url( 'admin-ajax.php' )
) );

此处的 FrontEndAJAX 必须替换为编写 ajax 代码的 js 文件的名称。

如果设置正确，您可以将您的网址设为：ajax.url

修复操作

我不确定您是在前端还是只是在管理区域运行它。如果它在前端，你需要添加这个。

add_action( 'wp_ajax_load-all-filter','prefix_load_all_cat_posts' );
add_action( 'wp_ajax_nopriv_load-all-filter','prefix_load_all_cat_posts' );
