php include() help

phybertek

Hello,

I'm writing php code that uses templates and sucks in components. Basically, when I parse a templet, I rewrite it and return it back to the browser.

ob_start();
include( page.php );
$s=ob_get_contents();
ob_end_clean();

What I would like to do is pass the include file encode data this is passed from forms (ie: page.php?name=Mark&age=27). What happens is, when my template builds the page, I'm loosing data that is passed to template form. Does anyone know how to approach this problme?

try like this

name=Mark;
age=27;
include('page.php');

and call the value of name and age from the page

sorry put an open quote to each value coz it will give you an error

do it like this 🙂

name='Mark';
age=27;

Technically, you shouldn't loose data, make sure register_globals are set to Off. Super-variables such as $POST, $GET, $COOKIE, $GLOBALS and $SESSION have their own memory space and can be accessed from any scope. The vague one that confuses people is $REQUEST (which - ready for this could mean a value from $GET or a value from $POST - depending on the setting of your variables_order in php.ini. But it will only be set if it is populated by a form. If you explicitly define it like the example below it will be empty.... yes it's somewhat confusing.

$POST["elementname"] retrieves the form element from a method="POST".
$GET["elementname"] retrieves the form element from a method="GET" or passed thru the URL

Try this exercise:

<?php
$abc = "Private scope abc";
$_GET["abc"] = "123";
$_POST["abc"] = "321";
$_SESSION["abc"] = "session abc";
$_GLOBALS["abc"] = "globals abc";
$_REQUEST["abc"] = "request abc";

mydisplayvars()
//-- you can cut the code below into 
//-- another file and then do an include 
//-- of that file from this file and see how
//-- variables react with includes....

function mydisplayvars()
{
  echo "_GET = {$_GET['abc']}<br />";
  echo "_POST = {$_POST['abc']}<br />";
  echo "_SESSION = {$_SESSION['abc']}<br />";
  echo "_GLOBALS = {$_GLOBALS['abc']}<br />";
  echo "_REQUEST = {$_REQUEST['abc']}<br />";
  echo "abc = {$abc}";
}

?>

Being able to differentiate between a $GET and a $POST increases security measures without having to think about it. Using register_globals set to On, and just using plain variable names is just going to make things more difficult to manage as the program logic grows.
