I installed php, mysql and aparche 2.0
for some reason, I get this message when I use $_POST[delete] and $_GET[delete]. (delete is the name of a submit button)
Notice: Use of undefined constant delete - assumed 'delete' in C:\user\share\public\web\developer\guest_book\guest_modify.php on line 16
everything works fine, just keep getting this message.
line 16
if ($_POST[delete]){
Thank you,
Mike

The error message tells you exactly what it's looking for
Notice: Use of undefined constant delete - assumed 'delete' in C:\user\share\....
if ( $_POST['delete'] ) {
You must lookup those members as a string, unless already inside a literal string, where you should remove them
echo ( "The value for delete is $_POST[delete]" );

Line 46: if($_GET['mode'] == 'update'){

Try thisif ( isset( $_GET['mode'] ) && $_GET['mode'] == 'update' ) {

You were missing the single quotes around the variables inside the square brackets. An error if you calling in something that wasn't defined in the first place.

Well, again the error says it all
Undefined index: mode
That means the index 'mode' wasn't defined in the $_GET array at all. Since it's not defined, you can't check it's value and thus get that error.
You first need to see if it exists, which isset() is used for.
