[SOLVED] sessions

[zang8027]

What I am trying to do is when the session "cart" is created, create a constant with it. If it is already created, then the constant is already set, so use what is set. These constants will only be deleted when the user closes the site. Here is my code

 

<?php

// TESTING OUT CONSTANTS ******************
$restID = $_REQUEST['restId'];

if(! isset($_SESSION['cart']))
{
	$_CONSTANTS['restaurant'] = $restID;
	foreach($_CONSTANTS as $key => $val)
    			define($key, $val);
	$myConst = constant('restaurant');
}else{
	$myConst = constant('restaurant');
}

?>

 

 

Now, first time I go to the site, everything is fine. But once i refresh the page, it says it can not find the constant. Why can't it find it? It is supposed to be global.

Is session_start() at the top of your page?

Also, using $_REQUEST is risky.

[zang8027]

yes it is up there. How come it is risky, should i just use get?

im trying to use a new session now.

 

<?php
                $_CONSTANTS['restaurant'] = $restID;

	foreach($_CONSTANTS as $key => $val)
    			define($key, $val);

	$myConstant = constant('restaurant');
	$_SESSION['rest'] = $myConstant; //now session 'rest' is equal to my constant value

}else{


}

 

 

Now I want to set that session to a variable if possible to reference. Is that possible? See, I am using the value of this session to be passed to functions and pull information out of a database. Can i just pass a session through a function?

 

function name($_SESSION['cart']) ???

You can, but you do not need to. Inside the function you can access that by $_SESSION['cart'].

 

It depends on if you want your function to handle more than just session or not.

[zang8027]

so would

 

$query="Select * from myTable WHERE id=$_session['rest']";

 

 

be valid? Ill try that here in a few.

[premiso]

$query="Select * from myTable WHERE id={$_SESSION['rest']}"; 

 

That would be.
