foreach error

[astratt]

Can someone please take a look at this and tell me what I am doing wrong in this for each statement. I am getting this error:

 

Warning: Invalid argument supplied for foreach()

 

below is a snippet of my code:

 

$last_id = mysql_insert_id ();
// INSERT TeamMember IDs
if (!(count($userId) == 1 && $userId[0] == "")) {//dont save if first (blank) option is selected
    foreach($_POST[$userId] as $id){
    	$qry_insert = "INSERT INTO tblTeamMembers (ProjectID, UserID) VALUES('$last_id','$userId')";
        $qry_insert_rs  = $connector->query($qry_insert) or die(mysql_error());
     }
}

 

Any help would be greatly appreciated. Thanks.

Is $_POST[$userId] an array? Please show us the form that generates the data.
