将javascript变量分配给php变量并将其发布到另一页面上

Comment: Ajax added Assign javascript variable to php variable and post it on another page
I use the Fullcalendar (javascript). When you click on the event it opens a form with its content.
eventClick: function(calEvent, jsEvent, view) {
content.val(calEvent.content); //content of event
$('#event').show();
formOpen('edit');
},
I want to do that when you click on the event its opens another php page and displayed its data in it.I want to post value through the session,but i dont know how to assign javascript variable to php variable.
eventClick: function(calEvent, jsEvent, view) {
var content = content.val();
<?php
print <<<HERE
location.href = 'anotherpage.php?id=$_SESSION[id]';
HERE;
?>
<?php
$content = content;
$_SESSION['content'] = $content;
?>
},
P.S: ajax did not work because it seems that i have a bit of a particular situation.
$.ajax({
type: "POST",
url: "anotherpage.php",
data: {content: content.val()},
});
Anotherpage.php
<?php
$content = $_POST['content'];
?>
答
Use AJAX :
ajax will send data under the hood.
Ajax framework :
Add this frame work under <script> on your calender page.
function ajaxObj(meth, url) {
var x = new XMLHttpRequest();
x.open(meth, url, true);
x.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
return x;
}
function ajaxReturn(x){
if(x.readyState === 4 && x.status === 200){
return true;
}
}
How to use :
On your calendar page :
eventClick: function(calEvent, jsEvent, view) {
var content = content.val();
var ajax = ajaxObj("POST", "Currunt_page_url.php");
ajax.onreadystatechange = function() {
if(ajaxReturn(ajax) == true) {
}
}
//sends data by POST method to ur url page
ajax.send("contents="+contents);
}
Add this at start of your calendar page :
<?php
if(isset($_POST['contents'])){
//save data of contents into session
$SESSION['contents']=$_POST['contents'];
location.header='URL_of_php_page.php';
//access session['id']/session['contents'] on your php page though session variables.
exit();
}
?>
