you get the error because the $_POST variable has not been set. In other words, the form has not yet been submitted.
What you need to do is a statement that checks if the variable has been set. isset() is probably the best way to do this.
if(isset($_POST['name']))
{
//your form has been submitted and you can go on executing you query message.
}
it is probably a good idea to do this with all your variables, assuring that the user has submitted anything.
If you just want to remove the error, you can put an @ before $_POST['name']
the @ silences any errors made by $_POST

Changed thread title to better describe the problem (did you know that threads whose titles contain only one word. such as, 'error' actually get FEWER responses?).

As a side-note, the second method is not recommended, but it is completely possible. Suppressing error messages is only useful before you know how to use try...catch statements on functions that deal with file handling or database connections. Also, the only other acceptable time to use it is if the error message would display private information that could compromise security.

As others have said, your form did not post a 'name' variable. Remember, array indexes are case sensitive, so $_POST['name'] and $POST['Name'] are different fields.

I decided to run some code with errors set to E_ALL, just to see what I
would run across. It caught a few things, but 90% or better of the
messages were of the 'undefined' kind:
PHP Notice: Undefined variable
PHP Notice: Undefined index
PHP Notice: Undefined property
I'd like to go back and fix what I can, but I'm wondering: how good or
bad is this? I mean, I rely on the fact that the first use of a variable

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
