Reset to default 2You can not assign client side variable(Javascript) to server side variable(PHP).
You have to use ajax to do this.
<script>
function assignJsValueToPHPSession()
{
var jsVar = 1;
$.ajax({
type:post,
url: "test.html",
data: 'sessionjsvar=' + jsVar,
success: function(){
$(this).addClass("done");
}
});
}
test.php
<?php
$_SESSION['phpvalue'] = $_POST['sessionjsvar'];
?>
You can set cookie using javascript and the same cookie will be accessible in server side variable(PHP).
$.cookie("name1", "test"); // emample 1
$.cookie("name1", "test", { expires: 7 }); // emample 2
$.cookie("name1", "test", { path: '/User', expires: 7 }); // emample 3
Get a cookie
alert( $.cookie("test") );
//In PHP
<?php
print_r($_COOKIE);
print)r($_REQUEST);
?>
$_SESSION['id'] = $_GET['c']
set the GET parameter you sent to a session variable.
$_SESSION['id'] = $_GET['c']
Just check c is really in the URL first.
