Could you elaborate, (poosibly I'm just thick but I don't understand)

....and shouldn't that be 'lovelies'?

You can find your variables in the $HTTP_POST_VARS array.

Hi,

Thanks for replying.

What I have is a php page, where I want to get the information from only the form on the preceding page. I know i can just make the variable $name_from_filed_of_form, but the problem is that I also have a variable from a querystring which has the same name as the one from the form.

So... how can i request a variable from a form and not a querystring and vice versa?

Jack: could you elaborate on your answer a bit?

Alice,
I don't think you can differentiate between the querystring and the form like you can in ASP (I'm not positive). You may want to consider changing the name of your querystring variable to something that is not used in the form.

There are two global variables created by PHP automatically:

$HTTP_POST_VARS

This is an associative array of any values submitted via form post. You would access them by name, for example:

$field_value = $HTTP_POST_VARS['my_form_field_name'];

This is the equivalent of ASPs Request.Form("field_name").

---

$HTTP_GET_VARS

This is an associative array of any values passed over the query string.

This is the equivalent of ASPs Request.QueryString("field_name").

Hope this helps,
Jack

Exactly. And as an alternative, you can test the value of $REQUEST_METHOD and branch to different sections of code base on whether it's a POST or a GET.
