Field Selection question

[rolf_mactherapy]

Hi,

I need help with the following:

I have a dynamic menu populated from a mysql database in a web page, I also need to have a text field next to it so that if the required name is not in the menu the user can add it.

I know I need something that says " if the text field is empty then let the menu selection be the value, if an item is selected from the menu then ignore the text field" The question is how do I do this?

I need a line of code that will look at the menu input and text field input and use the proper selection...

Help!

Thanxs in advance.

The best bet would be something like this...

if (empty($HTTP_POST_VARS["inputfield"]) )
{
// use the selection value
}
else
{
// add the users input
}

Does that help?

Thanxs for the reply, I am still a bit confused though should it look like this?

if (empty($HTTP_POST_VARS["clientname"]) )
{
// use the selection value
clientmenu
}
else
{
// add the users input
clienttext
}

Assuming the 2 imput fields are:

<input name="clienttext" type="text" id="clienttext"></td>

and

<td width="480"> <select name="clientmenu" id="clientmenu">

Obviously this gives me an error, what should I do?
