如何从HTML表单发送JSON请求并在PHP中接收 [英] How to send JSON request from HTML form and receive in PHP

问题描述

我使用具有多个字段的HTML表单. 但是我需要将选择字段(下拉列表)中的值转换为php aray. 我的表单包含以下字段:

I use a HTML form with several fields. But i need to have the value from the select fields ( dropdown ) translated into a php aray. My form contains below fields:

City - Text
IN - Text/Date
OUT - Text/Date
Rooms - Select ( 1->5 )
Adults - Select ( 1->5 )
Childs - Select ( 0->5 )

我需要接收的php数组是

The php array that i need to receive is

Example If Rooms is - 1 and Adults - 2 the response must be:
$rooms[] = array(array("paxType" => "Adult"), array("paxType" => "Adult")); 

Example If Rooms is - 2 and Adults - 3 the response must be:
$rooms[] = array(array("paxType" => "Adult"), array("paxType" => "Adult")); 
$rooms[] = array(array("paxType" => "Adult")); 

我正在使用以下代码

$Adults = intval($_POST["Adults"]);
$rooms = array();
for ($x = 0; $x < $Adults; $x++) {
    array_push($rooms,array("paxType" => "Adult"));
}

但是我只能得到1个房间和1个成人的答复.

but i am receive onbly the response with 1 room and 1 adult.

推荐答案

即使使用简单的HTML表单提交(也可以通过JSON XHR请求完成)，也很容易做到这一点

It is easy to do this, even with plain HTML Form Submit ( can be done with JSON XHR request too)

我假设您的SELECT HTML表单元素名称为"adultCount"

I assume that your SELECT HTML form element name is "adultCount"

$adultCount = intval($_GET["adultCount"]);
$rooms = array();
for ($x = 0; $x < $adultCount; $x++) {
    array_push($rooms,array("paxType" => "Adult"));
} 

仅供参考，即使我们可以将SOAP用于网页，也不会使用SOAP.

FYI, We don't use SOAP for web pages, even though it can be done ( it is unnecessary).
