如何通过jQuery.ajax将JavaScript数组发送到PHP? [英] How to send an JavaScript array to PHP via jQuery.ajax?
问题描述
我正在尝试通过jQuery.ajax将JavaScript数组发送到PHP页面，但是该数组仅使用空白值发送.
I'm trying to send a JavaScript array to a PHP page via jQuery.ajax, but the array is sent only with blank values.
如果我在Chrome上打开F12控制台并检查JS对象，则该对象在那里.全部填满.但是，当我使用ChromePhp工具记录PHP变量时，它仅显示空白值(此外，如果我遍历php数组并回显其值，则会得到所有空白).
If I open the F12 Console on Chrome and check for the JS object, it's there. All filled up. But when I log the PHP variable using the ChromePhp tool, it shows only the blank values (also, if I iterate over the php-array, echoing its values, I get all blanks).
我在这里很困惑.
这是我的示例代码:
<?php
include 'ChromePhp.php';
if (isset($_GET['newUsers'])) {
$newUsers = $_GET['newUsers'];
ChromePhp::log($newUsers);
} else { ?>
<html>
<body>
<script src="js/jquery-2.0.3.min.js"></script>
<script type="text/javascript">
var newUsers = [];
newUser = [];
newUser['nome'] = 'alvaro';
newUser['idade'] = '34';
newUsers.push(newUser);
newUser1 = [];
newUser1['nome'] = 'bia';
newUser1['idade'] = '7';
newUsers.push(newUser1);
newUser2 = [];
newUser2['nome'] = 'alice';
newUser2['idade'] = '2';
newUsers.push(newUser2);
$.ajax({
url: "testcookie.php",
type: "GET",
data: {
'newUsers[]': newUsers
}
});
</script>
</body>
</html>
<?php } ?>
已更新基于第一条评论.现在，我可以传递对象，但是不知道如何读取其属性.已经尝试$ user ['nome']，但没有结果.
Updated Based on the first comments. Now I get to pass the object, but don't know how to read its properties. Already tried $user['nome'] with no result.
<?php
include 'ChromePhp.php';
if (isset($_POST['newUsers'])) {
$newUsers = $_POST['newUsers'];
foreach ($newUsers as $user) {
# code...
# HOW DO I READ THE nome AND idade VALUES HERE?
}
} else { ?>
<html>
<body>
<script src="js/jquery-2.0.3.min.js"></script>
<script type="text/javascript">
//var newUsersObj = {};
var newUsers = [];
newUser = {};
newUser['nome'] = 'alvaro';
newUser['idade'] = '34';
newUsers.push(newUser);
newUser1 = {};
newUser1['nome'] = 'bia';
newUser1['idade'] = '7';
newUsers.push(newUser1);
newUser2 = {};
newUser2['nome'] = 'alice';
newUser2['idade'] = '2';
newUsers.push(newUser2);
$.ajax({
url: "testcookie.php",
type: "POST",
data: {
'newUsers[]': newUsers
},
success: function () {
},
error: function () {
}
});
</script>
</body>
</html>
<?php } ?>
推荐答案
知道了！
要正确访问PHP中的JavaScrtipt对象，在推送数组时，需要 JSON.stringify .然后，在PHP上，将它们 json_decode 转换为PHP对象，并使用'->'运算符访问其属性.
To properly access the JavaScrtipt objects in PHP I need to JSON.stringify them when pushing on the array. Then, on PHP, json_decode them to a PHP object, and access their properties with the '->' operator.
最终解决方案如下:
<?php
include 'ChromePhp.php';
if (isset($_POST['newUsers'])) {
$newUsers = $_POST['newUsers'];
foreach ($newUsers as $user) {
# code...
$usr = json_decode($user);
ChromePhp::log("Nome: " . $usr->nome . " - Idade: " . $usr->idade);
}
} else { ?>
<html>
<body>
<script src="js/jquery-2.0.3.min.js"></script>
<script type="text/javascript">
//var newUsersObj = {};
var newUsers = [];
newUser = {};
newUser['nome'] = 'alvaro';
newUser['idade'] = '34';
newUsers.push(JSON.stringify(newUser));
newUser1 = {};
newUser1['nome'] = 'bia';
newUser1['idade'] = '7';
newUsers.push(JSON.stringify(newUser1));
newUser2 = {};
newUser2['nome'] = 'alice';
newUser2['idade'] = '2';
newUsers.push(JSON.stringify(newUser2));
$.ajax({
url: "testcookie.php",
type: "POST",
data: {
'newUsers[]': newUsers
},
success: function () {
},
error: function () {
}
});
</script>
</body>
</html>
<?php } ?>
