foreach loop and $_SESSION

[low-rider]

hi,

 

i have an array of food names and im using $_SESSION to pass the variables to another php.

 

if i enter foreach($_SESSION["food"] as $foodNames) {

echo $foodNames"; }

 

i get en error saying Invalid argument supplied for foreach()

 

what am i doing wrong???

do a print_r( $_SESSION ); to see what is in the session.

 

But I expect you have forgotten:

 

session_start() -- http://uk3.php.net/function.session-start

do a print_r( $_SESSION ); to see what is in the session.

 

But I expect you have forgotten:

 

session_start() -- http://uk3.php.net/function.session-start

session_start() is declared at the very top of my page....

 

this is what i have at the top:

 

<?php

session_start();

$_SESSION["food"] = $food;

 

$fullName=$_GET["fullName"];

$houseNN=$_GET["houseNN"];

$streetName=$_GET["streetName"];

$town=$_GET["town"];

$county=$_GET["county"];

$postCode=$_GET["postCode"];

$country=$_GET["country"];

?>

 

this is where i want to echo array FOOD! and underneath in a table, i have the foreach loop!

 

[monk.e.boy]

so did you do the:

 

do a print_r( $_SESSION ); to see what is in the session.

this is what i got

 

Array ( [food] => [QHat] => 1 [QBag] => 1 [QBall] => 1 [product] => poo )

That's telling you that $_SESSION['food'] is set to nothing. Please show us the code where you set the session variable.

 

Also, if you dump the $_SESSION array with

<?php
echo '<pre>' . print_r($_SESSION,true) . '</pre>';
?>

the output is much more readable.

$_SESSION["food"] = $food;

 

I expect $food is null.
