[SOLVED] register global off, Notice: Undefined variable: action in.... problem

[bbmak]

Hi,

I used to built script with register global on in php 4, but after they released php 5, register global is off

 

 

 

the problem is I used " if ($action ==  " in my script.

The script will show error " Notice: Undefined variable: action in...."  in php 5 with default register global off

 

Although, I can build the script will an emulation of register global on with the following code

<?

// Emulate register_globals on

if (!ini_get('register_globals')) {

$superglobals = array($_SERVER, $_ENV,

$_FILES, $_COOKIE, $_POST, $_GET);

if (isset($_SESSION)) {

array_unshift($superglobals, $_SESSION);

}

foreach ($superglobals as $superglobal) {

extract($superglobal, EXTR_SKIP);

}

}

?>

 

 

 

I want to know how do I overcome this problem? I want to use 'if ($action ==' but i want the register global stays off.

 

 

I do not always want to use register global emulation script and I do not want to make the php5 to register global on.

Use $_GET, $_POST, or $_REQUEST instead.  Example:

 

$action = isset($_REQUEST['action']) ? $_REQUEST['action'] : '';

Where does $action variable get set at?

 

Is it a POST or a GET form somewhere?

You can use:

if (!ini_get('register_globals')) {
  extract($_REQUEST);
  extract($_SERVER);
}

after using this u can use  following stuff

if($action)

Yes, you can do that tapos, but this is old style and outdated way of doing things. Also, why create and use up extra memory with more variables when they're all already populated in predefined variables for you.

toplay can you show me how to replace my code here with $_request ???

 

if ($action == 'show')

{

...

}

what is the colon for : ? in this  $_REQUEST['action'] : ???

If you have any common file. like as DB connection or Config file which is included in all files Then you can metion.

 

extract($_REQUEST); in first line.

 

This is just temporaly solution.

To know more about the ? : syntax, look for ternary operator info on this manual page:
