Function array and passing string
Posted: Fri Apr 06, 2012 10:26 pm
Trying to pass a string from within a page that loads a module called structure.php which controls a navigational bar, so page specific help popup may be loaded. I've named this string $helpPage, my problem is that each variable is only valid in its own scope, meaning that variables created inside a function are not visible outside of this function. I need to know how to get "my-gallery" string inside this function. I appreciate all help for writting this code and appreciate you giving up your time to help.
MAIN FILE
Now for the structure.php file code and the Function User Bar and array
Thanks for your time. I hope my instructions are clear.
MAIN FILE
Code: Select all
<?php
include_once("common.php");
include ("includes/html/structure.php");
include ("modules/gallery/funcs.php");
//ini_set('display_errors', '1');
//error_reporting(E_ALL);
extract($_POST);
extract($_GET);
$userID = $_SESSION["userid"];
if (!$userID)
exit;
$query = "SELECT * FROM " . userTable . " where id=$userID";
$db->setFetchMode(DB_FETCHMODE_ASSOC);
$arrUser = $db->getAll($query);
// check actions
// TODO: messy code, extract should never be used, change it!!!
if ($add_gal)
addGal();
if ($_POST['op'] == 'update')
editGal();
if ($_POST['op'] == 'delete')
delGal();
$arrGalleries = getGalleries($userID);
$arrCount = getImageCountPerGallery($userID);
head('Card -> Galleries');
userBar(
array(
'index.php?id=' . $cardId => 'Close My Galleries' )// this creates the item "Close My Galleries" in the menu bar, This section of code is where $helpPage needs to be equal to 'my-gallery' and passed to the menu bar to make $helpPage available
);
?>
....
Code: Select all
<?php
function head($title = 'Card', $additional = '')
{
?>
