I keep getting this error while trying to use the field 'ID' to pass in a url..
And it's odd because the query is pulling everything BUT the ID which is the
first field...
code:
<a href="view.php?ID=<?php echo $_SESSION['fullRestaurantList']['ID']?>"><?php
echo
htmlspecialchars(stripslashes($_SESSION['fullRestaurantList'][$i]['name'])); ?>
We're going to need to know how the $_SESSION['fullRestaurantList'] gets
populated. Also, where do you define $i? Is $i the ID? Seemed like you've
built an array of arrays and you may want
$_SESSION['fullRestaurantList'][$i]['ID'], or just $i. This is all speculation
from the 2 lines of code I've seen though.

The full script is (I have my Entourage email settings on html so I hope this
displays ok for you all---seems I've been told it turns into a mess in some
views) :
