Question

我正在接管一个wordpress网站，我已经从wordpress转移到了azure。该网站底部有一个按钮，点击后会发送一封电子邮件。这是onclick方法的html

<div class="w-form-json hidden" onclick="return {ajaxurl:http:\/\/loancoreignite.azurewebsites.net\/engine\/wp-admin\/admin-ajax.php,success:Thank you! Your message was sent.,errors:{name:Please enter your Name,email:Please enter your Email,phone:Please enter your Phone Number}}"></div>

当我转到那个ajax url时，我在调试工具中的左上角出现了0错误，出现404错误。所以我找到了admin-ajax.php文件并尝试从那里搞清楚，但这是我迷路的地方。以下是admin-ajax.php文件。

    <?php
/**

define( 'DOING_AJAX', true );
if ( ! defined( 'WP_ADMIN' ) ) {
    define( 'WP_ADMIN', true );
}

require_once( dirname( dirname( __FILE__ ) ) . '/wp-load.php' );

    die( '0' );

add_action( 'wp_ajax_nopriv_heartbeat', 'wp_ajax_nopriv_heartbeat', 1 );

if ( is_user_logged_in() ) {
    /**

    do_action( 'wp_ajax_' . $_REQUEST['action'] );
} else {
    /**

     */
    do_action( 'wp_ajax_nopriv_' . $_REQUEST['action'] );
}
// Default status
die( '0' );

也许这比实现它更容易，所有需要的东西都是wordpress中的东西？

Answer 1

你可能不是，但我觉得有义务说出来：

请永远不要编辑WP Core文件!!

至于你的问题，可能是很多事情。 WP Ajax需要一个＆＃39;动作＆＃39;要设置。有关设置AJAX＆＃34;操作＆＃34;：https://codex.wordpress.org/Plugin_API/Action_Reference/wp_ajax_(action)

的更多信息，请参阅此链接

其次，当WP AJAX返回0时，这意味着AJAX＆＃34; action＆＃34; （如上所述）无法找到或者PHP函数最后没有die()。您必须在AJAX触发的PHP函数末尾添加die();，必须从上面的链接声明操作。

创建一个PHP函数以在functions.php文件中发送电子邮件。从上面的链接创建操作并将回调设置为PHP函数。在函数结束时，放置die();然后事情应该按预期开始工作。

有两种类型的AJAX操作，wp_ajax-your-function和wp_ajax_nopriv-your-function。两个中的第一个将允许您的AJAX请求从wp-admin完成，第二个（_nopriv）将允许您从前端触发您的ajax请求。

如果您需要一个例子，请问。我可以从现有网站中提取一个来向您展示。

Answer 2

需要修复你的JSON

<div class="w-form-json hidden" onclick="return {ajaxurl:'http:\/\/loancoreignite.azurewebsites.net\/engine\/wp-admin\/admin-ajax.php',success:'Thank you! Your message was sent.',errors:{name:'Please enter your Name',email:'Please enter your Email',phone:'Please enter your Phone Number'}}"></div>

即使我仍然没有看到它是如何做的。
