can anyone help???

Hi, I am new to PHP and I keep getting the same errors - for all of my PHP scripts

"Notice: Undefined index: tireqty in C:\Documents and Settings....."

I feel I have a problem with possibly Global variables?? although i have switched them to 'on' in .ini file

Thanks

Sally 😕

The notice is saying that you're using a variable before ensuring that it has a value. When the script gets to the line cited in the message, there is some array that has an index 'tireqty', but that array element doesn't exist. I'm guessing the array is $GET or $POST, and the form field is not filled in.

You should check that variables exist (using [man]isset[/man] or [man]empty[/man]) before using them, but Notice: level messages can be turned off using [man]error_reporting[/man].

Hi, thanks for the reply But I am still having probs! Have the way to create variables changed recently?? I had this code working several months ago! I have attached the code - as you can see i have declared the variables using different methods - all of which are producing error messages (see below)

PHP Notice: Undefined index: DOCUMENT_ROOT in F:\www\~scp.php on line 2 PHP Notice: Undefined index: oilqty in F:\www\~scp.php on line 3 PHP Notice: Undefined index: sparkqty in F:\www\~scp.php on line 4

the code:

<?php //create variable names in long name
$tireqty = $_SERVER['DOCUMENT_ROOT'];
$oilqty = $HTTP_SERVER_VARS['oilqty'];
$sparkqty = $HTTP_POST_VARS['sparkqty'];
?>
<html>
<head>
<title>bobs auto parts - order results</title>
</head>
<body>
<h1>Bobs auto parts</h1>
<h2> Order results</h2>

<?php echo '<p>Order processed at ';
echo date('H:i, jS F');
echo'</p>';

echo '<p>Your order is as follows: </p>';
echo $tireqty.'tyres<br />';
echo $oilqty.'bottles of oil<br />';
echo $sparkqty.' Spark plugs<br />';
?>
</body>
</html>
