How to retrieve data from jQuery.Post() in PHP?
提问by user1055650
I am currently trying to send a string to a to a php script which will eventually return a JSON file. Here is code i'm using to send the string:
我目前正在尝试将字符串发送到 php 脚本，该脚本最终将返回一个 JSON 文件。这是我用来发送字符串的代码：
var str = "testString";
$.post("php/getTimes.php", str,
function(data){
console.log(data.name);
console.log(data.time);
}, "json");
In the 'getTimes' php file I am simply trying to receive the 'str' variable I am passing. Any ideas how to do this? It seems like it should be pretty simple.
在'getTimes' php 文件中，我只是想接收我传递的'str' 变量。任何想法如何做到这一点？看起来应该很简单。

You have to name attributes in POSTdataeither with serialized string:
您必须使用序列化字符串在POST 中命名属性data：
var data = "str=testString";
$.post("php/getTimes.php", data, function(json) {
console.log(json.name);
console.log(json.time);
}, "json");
or with map:
或地图：
var data = {
str : "testString"
};
$.post("php/getTimes.php", data, function(json) {
console.log(json.name);
console.log(json.time);
}, "json");
To handle this variable in PHP use:
要在 PHP 中处理这个变量，请使用：
$str = $_POST['str'];

In getTimes.php:
在 getTimes.php 中：
<?php
$var = $_POST['string']; // this fetches your post action
echo 'this is my variable: ' . $var; // this outputs the variable
?>
Also adjust:
还要调整：
$.post("php/getTimes.php", str,
to
到
$.post("php/getTimes.php", { string: str },
