问题描述
两者我的 jQuery 代码和 PHP 代码在同一PHP文件中(不是两个单独的文件).
Both my jQuery code and PHP code are in the same PHP file (not two separate files).
我想将jQuery变量发布到PHP代码.
I want to POST jQuery Variable to the PHP code.
但是在运行PHP文件时会显示一些错误(未定义的索引").
But it Shows some errors ("undefined index") when running the PHP file.
PHP文件如下(test.php).
PHP file is as follows (test.php).
<?php
$country = $_POST['userCountry'];
$ip = $_POST['userIp'];
echo $country;
echo $ip;
?>
<html>
<head><title></title>
<script src = "jquery.min.js"></script>
<script>
$.getJSON("http://freegeoip.net/json/", function(data) {
var country = data.country_name;
var ip = data.ip;
$.ajax({
method:"POST",
url:"test.php",
data:{userCountry:country, userIp:ip}
});
});
</script>
</head>
<body></body>
</html>
