PHP表单post被调用两次

我有一个表单发布到它声明的同一页。问题是，它在提交时似乎被调用了两次。代码如下：

function user_data_form() {

    add_ajax_validation();

    // Form verication start
    if (isset($_POST["action"])) {
        switch($_POST["action"]) {
            case "validate_form":
                ajax_validate();
                break;
            case "update_user_data":
                $wp_user_object = wp_get_current_user();
                $id = $wp_user_object->ID;
                if ( 0 == $wp_user_object->ID ) {
                    redirect(get_permalink(get_page_by_title( 'Sign in' )), array(
                        "message" => 8
                    ));
                } else {
                    $form_data = array(
                        "verified" => false,
                        "email" => $_POST["email"],
                        "first_name" => $_POST["first_name"],
                        "last_name" => $_POST["last_name"],
                        "password" => $_POST["password"],
                        "old_password" => $_POST["old_password"],
                        "verify_password" => $_POST["verify_password"]
                    );
                    $form_data["verification"] = array(
                        "old_password" => wp_check_password($form_data["old_password"], $wp_user_object->user_pass, $id),
                        "email" => validate("email", $form_data["email"]),
                        "password" => validate("old_password", $form_data["old_password"]),
                        "verify_password" => validate("verify_password", $form_data["old_password"], $form_data["verify_password"])
                    );
                    if ($form_data["verification"]["old_password"]) {
                        if ($form_data["email"] != $wp_user_object->user_email && $form_data["verification"]["email"]) {
                            invalidate_email($id, $form_data["email"]);
                            $message = message('success', 'Account information updated, an email has been dispatched to <strong>'.$form_data["email"].'</strong> with details on how to confirm your new email address');

                        }
                        if ($form_data["last_name"] != $wp_user_object->get("last_name")) {
                            update_user_meta($id, 'last_name', $form_data["last_name"]);
                        }
                        if ($form_data["verification"]["password"]["result"] && $form_data["verification"]["verify_password"]["result"]) {

add\u shortcode（'user\u data\u form'，'user\u data\u form'，134）

将

放入

无效电子邮件功能中，调查并检测您收到的参数。
我以前在mail（）中注意到了这一点。如果在headers部分中有一个“To”，在mail（）的第一个参数中有一个“To”变量，则会发送两次。您可能想删除标题的一部分，并尝试

我应该仔细阅读这个问题。
我觉得自己像个傻子，但我刚刚意识到这是自己造成的。我有一段代码试图避免WordPress的自动格式化功能
wpautop
。它似乎发射了他们两次

function pre_process_shortcode($content) {
    global $shortcode_tags;
    // Backup current registered shortcodes and clear them all out
    $orig_shortcode_tags = $shortcode_tags;
    $shortcode_tags = array();
        add_shortcode('registration_form', 'registration_form', 134);
        add_shortcode('login_form', 'login_form', 134);
        add_shortcode('user_data_form', 'user_data_form', 134);
        add_shortcode('activation_code', 'activation_code', 134);
        add_shortcode('logout_code', 'logout_code', 134);
        add_shortcode('reset_password_form', 'reset_password_form', 134);
    // Do the shortcode (only the one above is registered)
    $content = do_shortcode($content);
    // Put the original shortcodes back
    $shortcode_tags = $orig_shortcode_tags;
    return $content;
}

add_filter('the_content', 'pre_process_shortcode', 13);

我将此更改为：

    add_shortcode('registration_form', 'registration_form', 134);
    add_shortcode('login_form', 'login_form', 134);
    add_shortcode('user_data_form', 'user_data_form', 134);
    add_shortcode('activation_code', 'activation_code', 134);
    add_shortcode('logout_code', 'logout_code', 134);
    add_shortcode('reset_password_form', 'reset_password_form', 134);

这当然会产生其他问题，但至少它解决了这个问题，我会找到另一种方法来做我以前想做的事情。很抱歉，有人花时间试图解决此问题，因为根据我提供的信息，您永远无法解决此问题。
向我们展示函数invalidate_email（）@Duniyadnd Updated question谢谢，现在我要要求展示email（）函数-我猜这就是邮件（）的位置正在调用函数。@Duniyadnd已更新问题。。。它调用
wp\u mail（）
，这是WordPress CMS的内置功能，与您的问题无关，但我建议不要使用“global$current\u user；”它只接收要发送的参数-
$user\u id
和
$new\u email
。我不确定这有助于理解为什么它被调用了两次。请确保函数没有收到重复的函数，因此在此函数中之前没有收到重复的函数…抱歉，我不太理解。我认为您收到了两次，因为您从函数收到了两次。您收到2个参数，但未收到，因此，在此函数之前，它已通过。在这个函数之后，有些东西不起作用了。谢谢，但不仅仅是邮件被发送了两次，而且每次生成一个新的不同的
$activation\u url
时，这个函数都会被调用两次。
