AMP表格提交帖子

Pat*_*aaf 6 php forms post amp-html

我有一个网站多年,有一些表格可以登录等.最近我做了所有谷歌的AMP证明,但表格停止工作.我现在正在寻找几天,但我找不到合适的答案.

首先,我包含了所有必要的脚本和代码,就像在此页面上一样.之后,出现了第一个错误:"表单提交失败::响应必须包含AMP-Access-Control-Allow-Source-Origin标头".

然后我在页面中添加了标题.之后,第一个错误消失,但出现第二个错误:"表单提交失败::意外令牌<在位置0的JSON中".我在这里读过这个,但它对我来说没有真正的解决方案.

在这个阶段,我陷入了困境,我认为我走错了道路就像这样一个简单的形式.我只想回应一下输入......你能帮我吗？

亲切的问候,

帕特里克

简单地说:你不能只是回应输入.

来自文档:

使用action-xhr属性通过XMLHttpRequest(XHR)提交表单.您可以使用amp-mustache模板显示自定义成功或错误消息,使用服务器端点发送的数据作为JSON.例如,如果服务器发送{"foo":"bar"},您可以在模板中使用{{foo}}来渲染条形图.

因此,既然您正在使用action-xhr,那么您应该返回一个JSON,并相应地更新表单模板.

看看这个.

完整示例,来自您的代码:

<?php
if(isset($_POST['submitlogin']))
{
    $name = isset($_POST['name']) ? $_POST['name'] : '' ;
    $output = [
            'name' => $name
    ];
header("Content-type: application/json");
header("Access-Control-Allow-Credentials: true");
header("Access-Control-Allow-Origin: *.ampproject.org");
header("AMP-Access-Control-Allow-Source-Origin: https://www.domain.com");
header("Access-Control-Expose-Headers: AMP-Access-Control-Allow-Source-Origin");

echo json_encode($output);
die();

}
