Answer 1

i want to pass a uid to next page through querystring.how i pass it and how i get it on next page?

You can create a link like this:

<a href="page.php?var=value">Go</a>

The variable-value pair after ? will create the query string. Later you can get the query string with $_GET array like $_GET['var'] for example.

Answer 2

You can also pass the value from one page to another page using SESSION.

session_start(); 
$_SESSION['variable name']=$var;

$var is the variable where you store the value that you want to pass to next page and variable name is name of session variable .

In the Next page where you want to fetch.

session_start();
$a=$_SESSION['variable name'];

$a in which you get the value that you store on the previous page.

Answer 3

There are several ways to do that:

1. For links: pass "uid" as GET parameter in all links: <a href='something.php?uid=$uid ... '

2. For forms: pass "uid" as POST parameter, this can be done with <input type='hidden' name='uid' value='$uid'>

3. Also, you may use cookies, see the following article for details: http://php.net/manual/en/function.setcookie.php

//if your data is not danger and Sensitive information send like this

$uid="your variable";
header("location:page.php?uid=$uid")

// get like this in another page (page.php)

$uid=$_GET['uid'];

//if your data is Sensitive information like pass use it

$_SESSION['uid']="your variable";
header("location:page.php?uid=$_SESSION['uid']")

// get like this in another page (page.php)

$uid=$_SESSION['uid'];
