how to validate form data

[xiaopang]

Hello,

If I want to validate the form input, let's see if it is a email and I
don't need to store this input in to database, which means the
$validate array can't do the validation.

In this case, besides writing reg express, does cakephp provide any
validation mechanism?

How to add global variable

[xiaopang]

Hello:

I am a newby to Cakephp,

I have some simple data which I don't want to store in database but I
want them to be application wide accessible. for view, controller as
well as model.

For example:  I have a array  $admin_type, which define 2 types of
system administer,

$admin_type =  array (1 = 'King',
  2 = 'Admin');

Then, where should I define this variable?   I tried to define in
bootstrap file, but it doesn't work


Thanks in advance
