PHP - Joomla variable $A not recognized

[dkas]

Working with PHP script and Joomla - When I define a variable in the script (see example 1 below), install the compoment in joomla, select the menu item, nothing happens. The error log says:

PHP Notice: Undefined variable: act in C:\\Program Files\\Apache Software Foundation\\Apache2.2\\htdocs\\joomla\\components\ \com_ectpequipmentlist\\ectpequipmentlist.php on line 37, referer: http://localhost/joomla/index.php

If I hard code a value in the default option of the script (see example 2), install the compoment, select the menu item the data appears correctly.

Example 1: Code that does not work:[php]global $database;
echo 'made it here';

include("class/ectpequipmentlist.php");
$EL = new EquipmentList();
switch( $act )
{
case 'search':
$EL->searchPosition($buildingid, $floor, $pos);
break;
case 'view':
$EL->viewPosition($positionid);
break;
default:
$EL->searchForm();
break;
}[/php]Example 2: Code that does work:[php]global $database;
include("class/ectpequipmentlist.php");
$EL = new EquipmentList();
switch( $act )
{
case 'search':
$EL->searchPosition($buildingid, $floor, $pos);
break;
case 'view':
$EL->viewPosition($positionid);
break;
default:
$EL->viewPosition('200');
break;
}[/php]

It most likely is not an error, but a notice or warning. Just means that you use a variable that has not been declared/initialized. It is always better to do that.

You can ignore this notice or set notices off completely in your PHP script.

Using PHP and Joomla - a define a variable run menu in Joomla and the error log says: Undefined variable in php script file. If I hard code a value the menu works correctly.

What missing?

You can add the @ symbol at the begging of the variable, to surpress an error.

Thank you for responding. I added some additonal information. I'm a newbie and I cannot get the code to work correctly unless I hard code a value.
