getting errors
Notice: Undefined index: name in F:\uni\Software
engineering\assignment4\guestbook.php on line 6
the variable $name is declared as $name = _POST["name"];
What could be causing this?
I've recently installed php 5 on IIS with mysql 4. All running on windows XP
downloaded code straight from my uni's tute site.
went to run it and it sort of runs but I get these errors at the top of the
page.
Thanks

While the city slept, news.bigpond.com (kh*******@bigpond.com) feverishly
typed... getting errors
Notice: Undefined index: name in F:\uni\Software engineering\assignment4\guestbook.php on line 6
the variable $name is declared as $name = _POST["name"];
Is this a typo in your post? Or does it appear *exactly* the same in your
code? It should be $name = $_POST["name"];
Cheers,
Nige

In $_POST['name'], 'name' is the undefined index if no 'name' has been
POSTed. For example, if you have a form whose action is itself, and in the
form php file you refer to $_POST['name'], 'name' is undefined until the
form is submitted.

PHP5 requires some extra checks AFAIU. You'll now need to use code such
as:
if (isset($_POST['name'])) {
/* do something with $_POST['name']... */
} else {
/* $_POST['name'] is undefined */
}
HTH =)

array_key_exists would be better in general...
From http://nl2.php.net/array_key_exists
"Example 2. array_key_exists() vs isset()
isset() does not return TRUE for array keys that correspond to a NULL
value, while array_key_exists() does.
<?php
$search_array = array('first' => null, 'second' => 4);
// returns false
isset($search_array['first'])
// returns true
array_key_exists('first', $search_array);
?>"
The chance of null values in POST/GET is quite minimal though :)

Ahh good point.. while true, you never know and if you can cater for
it........... =)
