index.js // linked to all php files.
var pass;
console.log(pass); // undefined
$("#btn").click(function() {
pass = "323";
location.href = "test.php";
});
going to test.php console.log shows again undefined.
I need to keep pass value as 323 accross all pages, once it is estblished.
Simplest method: Use localStorage.
If you only need to store strings:
var pass = localStorage.pass;
$("#btn").click(function() {
pass = "323";
localStorage.pass = pass;
location.href = "test.php";
});
Or, notice that localStorage will change all things you store in into string. So if you wanted to store object, numbers, etc, you need JSON.stringify.
// index.js
if (localStorage.pass === undefined)
localStorage.pass = "null";
var pass = JSON.parse(localStorage.pass);
$("#btn").click(function() {
pass = "323";
localStorage.pass = JSON.stringify(pass);
location.href = "test.php";
});
You can use the session to get your things work smoothly on all pages.
var pass;
console.log(pass); // undefined
$("#btn").click(function() {
pass = "323";
$.post('savesession.php','pass='+pass,function(){
console.log("session saved");
location.href = "test.php";
});
});
savesession.php
<?php
session_start();
$pass = $_POST['pass'];
$_SESSION['pass'] = $pass;
anypage.php
<?php
session_start();
$pass = $_SESSION['pass'];
