Re: [PHP] Class Function Problem

Where is the array $tools defined? The count() function returns the
number of elements in a variable (in this case an array).
It is seeing that there are 0 elements in the $tools array and
therefore your script is trying to divide 100 by 0 which
will spit out a warning every time. Should $tools be $toolsneeded
instead?

[PHP] Class Function Problem

[Sean Mayhew]

I have an admin panel that each section contains a set of tools so on each
page I can set $toolsneeded = "admin" or $toolsneeded = "employees"; etc.



I keep recieving this error:
Warning: Division by zero in /home/www/website/admin/include/adminclass.php
on line 250

Warning: Variable passed to each() is not an array or object in
/home/www/website/admin/include/adminclass.php on line 251

This is line 250:  $height = 100/count($tools);


Here is the page that uses the class.
SetContent($redux);

$toolsneeded = "admin";
$adminroot->SetTools($toolsneeded);

$adminroot->Display($employeeid,$password,$title);
?>




Here is my class file with some of the functions removed for brevity. I have
real problems understanding $this-> so you may find that Im using it in the
wrong place or not using it where I should be.

 "orders_root.php",
 "products" => "products_root.php"
 );
