created form vars and session vars

[Anon]

hey!

if I register a session variable (lets call it $name) on a page with a form that has a field by the same name (<input type="text" name="name">) and then submit the form, should the session variable inherit the posted value of the field?

did that make sense?

thanks! -craig

Hi Craig,
From what I understand of session variables, the blank (or previous value of the) session variable will override the form variable any time that you refer to it strictly as $name. If you want to set the session variable to the form variable, you would have to use syntax like:
$name=$HTTP_POST_VARS['name'];
From there it is fairly easy to do what you want with combination with a foreach loop:
foreach($HTTP_POST_VARS as $formName=>$inputValue) {
$$formName=$inputValue;
}
/This assumes that you already have session variables with the same name as form elements (for ALL of the elements) registered as sessions vars.../

Check me on the double variable, I just picked that up a little while ago: It should resolve to $name and then the name of whatever element that was.

Good Luck,
Jason
