[英]Is it possible to send a value of a variable from a js file to a php file
I have script and I'd like to know if it's possible the send the value of a variable to $_session, 我有脚本,我想知道是否可以将变量的值发送到$ _session,
<script>
$(function() {
var delivery = 0;
$('#jcart-paypal-checkout').click(function() {
delivery = $('form#delivery2 input[type=radio]:checked').val();
if(!delivery) {
alert('Please choose a delivery option');
return false;
}else {
<?php $_SESSION['shipping'] = ?> delivery;
}
});
});
</script>
I need to send the value of delivery in $_session['shipping'], 我需要在$ _session ['shipping']中发送交货价值,
thanks 谢谢
Yes, this is possible. 是的,这是可能的。 But you'll have to call the PHP-Script with POST or GET Parameters. 但是,您必须使用POST或GET参数调用PHP脚本。
Edit: But I don't think that you can put the variable directly into the session-array. 编辑:但是我不认为您可以将变量直接放入会话数组。
For example, use $.get()
: 例如,使用$.get()
:
$(function() {
var delivery = 0;
$('#jcart-paypal-checkout').click(function() {
delivery = $('form#delivery2 input[type=radio]:checked').val();
if(!delivery) {
alert('Please choose a delivery option');
return false;
}
$.get('putInSession.php', { d: delivery });
});
});
This snippet expects a script called "putInSession.php" on the server side, which should check the input parameter "d" and then 此代码段在服务器端需要一个名为“ putInSession.php”的脚本,该脚本应检查输入参数“ d”,然后
$_SESSION["shipping"] = $_GET["d"];
Optionally, you can specify a function that receives the result of the asynchronous request as third parameter of $.get()
. (可选)您可以指定一个函数,该函数接收异步请求的结果作为$.get()
第三个参数。
