javascript - 电子邮件未发送。 ajax发送的值

Question

我正在通过 AJAX 调用获取值并发送隐藏字段值，然后执行查询以更新数据库中的某些内容。第一个初始查询找到 id 和其他 $_POST信息和效果都很好。但是我的电子邮件没有发送。我的警报错误消息没有显示任何内容，但正在显示(它是一个空白警报)。

有人看到我如何尝试发送到我的电子邮件或我如何在我的电子邮件中获取它不会发送的值有任何问题吗？

隐藏输入字段..

<input type="hidden" value="<?php echo $approved_id; ?>" id="approved_id" name="id" />
    <input type="hidden" value="<?php echo $approved_firstname; ?>" id="approved_firstname" name="firstname" />
    <input type="hidden" value="<?php echo $approved_lastname; ?>" id="approved_lastname" name="lastname" />
    <input type="hidden" value="<?php echo $approved_username; ?>" id="approved_username" name="username" />
    <input type="hidden" value="<?php echo $approved_email; ?>" id="approved_email" name="email" />

ajax调用..

$(document).ready(function () {

    $('#update_group').on('submit', function (event) {
    event.preventDefault();
        $.ajax({
            url: 'user_group_update.php',
            type: 'POST',
            data: {
            id: $("#approved_id").val(), //id
            firstname: $("#approved_firstname").val(), //firstname
            lastname: $("#approved_lastname").val(), //lastname
            username: $("#approved_username").val(), //username
            email: $("#approved_email").val(), //email
           // update_group: $("#group_id").val() //group level
          update_group: $(this).find( "#group_id option:selected" ).val()
        },
            success: function (data) {
                //do something with the data that got returned
                $(".group_success").fadeIn();
                $(".group_success").show();
                $('.group_success').html('User Permission Level Changed!');
                $('.group_success').delay(5000).fadeOut(400);
                alert(data);
            },
             error: function(jqXHR, textStatus,errorThrown )
            {
              // alert on an http error 
              alert( textStatus +  errorThrown );
            }
        });
        return false;
    });
});

Answer 1

PHP 中的 mail() 函数将返回 true 或 false，因此您将无法在客户端。

但是，当 mail() 失败时，您可以使用 error_get_last() here .

由于 mail() 函数返回 true 或 false，您将能够创建一个简单的 if 语句来检查它是否成功:

if(mail($to,$subject,$message,$headers)){
     // success
} else { 
     print_r(error_get_last());
}

尝试此操作以获取有关后台发生的情况的更多信息。
