我在理解和实现AJAX的WP方式时遇到了很大的问题。我有一个“正常”的设置，只是在提交表单时，页面会用额外的页眉/页脚复制自己，这可能是必须的，我没有在wp的每个方面都这样做。叹气我真的很高兴它能正常运行，现在我必须用不同的方法重做它。

嗯，我知道我应该排队并本地化我的js，我已经在我的函数中完成了这项工作。php-这样可以吗？至少它已加载，但我以后无法完全使用它。我还知道本地化允许我使用管理ajax。应该使用php来完成此操作。是的，到目前为止还不错。我可以看到它已正确加载，并且具有指向管理ajax的正确路径。php检查我的页面时。

这就是我迷路的地方。我不知道该把什么代码放在哪里。我已经花了好几个小时试图重新排列代码，但我并没有走得更远。

这就是我目前拥有的-我应该怎么做？

解析器。php

    $name = $_POST[\'name\'];

    $message = nl2br($_POST[\'message\']);
    $to = "[email protected]";
    $from = $mail;
    $subject = \'Kontaktformulär från emcolsson.se ifyllt\';

    $headers .= "MIME-version: 1.0\\n";
    $headers .= "Content-Type: text/html; charset=utf-8\\n"; //Fixes ÅÄÖ in Sender name and Message


    if( mail($to, \'=?UTF-8?B?\'.base64_encode($subject).\'?=\', $message, $headers) ) { //Fixes ÅÄÖ in subject
