Undefine Index

Hi,

I'm getting this error:

Notice: Undefined index: btnEmpSearch in C:\Inetpub\wwwroot\automobile\employee.php on line 38

It shows when I run the script from localhosts, but it disappear when it is run from your domain.

The error messages occurs on this line:
if ($_POST["btnEmpSearch"] == "Search") {
echo "Hello World!";
}

How do u get rid of this error?

Thanks.

Dennis

either put error_reporting(E_ERROR | E_PARSE); at the top of the script or use [man]isset[/man] to determine if the variable is set before using it in code.

It works. But somehow, it does not pick up the value from the previous form. To solve it, I change the configuration to register_globals to ON.

Registering globals is bad batch - that's why it's now been turned off by default. Like Drew says, do some basic checking before with isset, or put an @ in front of it to subdue the error message.

Your server and local machine have different error reporting values set in php.ini, that's why they behave differently.
