Sheila,
I am at the stage a bit like the nascent swimmer made to take his feet off
the bottom; I've done that and I still can't swim! Hope to do better with
this ;-).
First the form. This will - I haven't got to it - be called by a php
script so the php should be read then. If not 'I'll be back'.
I follow the principle of the isset code, but don't yet grasp the code
itself. I don't know how much of the script to show you, but here is the
first twenty or so lines. I have already needed to set the top variables
and have now changed the $_REQUEST back for you to see::
<?php
include $_SERVER['DOCUMENT_ROOT'].'/layout.php';
//set some variables
$email_error = false;
$password_error = false;
switch ($_REQUEST['req']) {
case "process" : // code to process signup input and place in database
myheader("Become a member: step 2");
//Validate all required fields were posted
if(!$_POST['first_name'] ||
!$_POST['last_name'] ||
!$_POST['email_address'] ||
!$_POST['email_address2'] ||
!$_POST['username'] ||
!$_POST['password'] ||
!$_POST['password2'] ||
!$_POST['bio']){
$error = true;
$errors = "<h4>Form Input Errors:".
"</h4>\n\n";
if (!$_POST['first_name']) {
$errors .= "Missing first Name\n";
}
if (!$_POST['last_name']) {
$errors .= "Missing Last Name\n";
}
I also came across the point that use of $_REQUEST has security issues, but
imagine that is if it is overused rather than used where it is the best
option.
