checking session vars

I'm trying to do some validation with form data passed to a script and stored in session vars, but not getting very far

I have an array of session var names I want to check to make sure they aren't empty

PHP Code:

---

$req_vars = array("field1", "field2", "field3"); 


---

How can I get PHP to check each of those fields ensuring each has a value? This has really got me stumped. I'm using the $_SESSION thing BTW

Thanks

PHP Code:

---

if (($req_var[0] = "") || ($req_var[1] = "") || ($req_var[2] = "") ){
then do what you want...

}

wouldn't that work?

I don't think so since that would check $req_var[0] to see if it's empty rather than $req_var[0]'s value (being "field1")

Not as easy as it looks methinks

so field1 is the variable name in the session too?

well, for whatever the name of the session variable is can't you just do this.

if (session_registered(field1)) {



maybe I am confused here. what is the name of the session variable that is suppose to be in the session.

I solved it by forgetting the array of names and just checking them each manually.

Tedious but works, thanks anyways :cool:
