How to pass variables from one php page to another without form?

I want to know how to pass a variable from one page to another in PHP without any form.

What I want to achieve is this:

  1. The user clicks on a link
  2. A variable is passed which contains a string.
  3. The variable can be accessed on the other page so that I can run mysql queries using that variable.

If you are trying to access the variable from another PHP file directly, you can include that file with include() or include_once(), giving you access to that variable. Note that this will include the entire first file in the second file.

You can use Ajax calls or $_GET["String"]; Method

check to make sure the variable is set. Then clean it before using it:

isset($_GET['var'])?$var=mysql_escape_string($_GET['var']):$var='SomeDefaualtValue';

Otherwise, assign it a default value ($var='' is fine) to avoid the error you mentioned.

You want sessions if you have data you want to have the data held for longer than one page.

$_GET for just one page.

<a href='page.php?var=data'>Data link</a>

on page.php

<?php
echo $_GET['var'];
?>

will output: data

You can pass via GET. So if you want to pass the value foobar from PageA.php to PageB.php, call it as PageB.php?value=foobar.

In PageB.php, you can access it this way:

$value = $_GET['value'];

use the get method in the url. If you want to pass over a variable called 'phone' as 0001112222:

<a href='whatever.php?phone=0001112222'>click</a>

then on the next page (whatever.php) you can access this var via:

$_GET['phone']
