[Fwd: Re: [PHP] Undefined Index ...confusion]

Sorry, list, I did a reply instead of a reply-to-all. This is what I sent to "Miller, Terion" Miller, Terion wrote:

Thanks for the link Kyle!! Great thing there...(seriously I didn't know...I learn something everyday) Anyways the link to my script is: http://pastebin.ca/1504393 Your email client is annoying, it doesn't quote. Haha.

Anyway, so, you're loading up that array with arrays of arrays, here: 1.

     $position = 1;

2.

                                                                            3.
     while ($row = mysql_fetch_array
     <http://www.php.net/mysql_fetch_array>($result))

4.

       {

5.

           $_SESSION['fullRestaurantList'][$position] = $row;

6.

           $position++;

7.

       }

8.

         9.
       $_SESSION['totalNumberOfRestaurants'] = $position;

So, if you get 7 rows. Your array will have: Array => (Row 1 Data) Array => (Row 2 Data) .. etc You do not have ['fullRestaurantList']['ID']. In the page you're referencing you use something like $_SESSION['fullRestaurantList'][$i]['SomeValue']. I assume $i is the "Position" in the array, so you likely want to use $_SESSION['fullRestaurantList'][$i]['ID'] to get the ID field from that row. If you need a quick dump to better understand what data you have in your session, try making a page called session_dump.php in the same directory with this source: <pre><? print_r($_SESSION) ?></pre> That will give you a good idea of what your session array looks like, and you should see clearly that ['fullRestaurantList']['ID'] does not exist. Hope this helps! - Kyle
