I am having issues making sure that a field is unique. I am beginner
so please go easy on me. Right now, I am trying to create a simple
login system where the user name name and profile name have to be
unique. I have been cutting and pasting some stuff together and I
can't seem to get this to work out. Here is a sample of my 'create'
view:
<label for="profile">Profile Name:</label>
<?php echo $html->password('User/profile', array('size' => 20)); ?>
<?php echo $html->tagErrorMsg('User/profile', 'You need to enter a
profile name.') ?>
Now, here is my validation function:
var $validate = array(
'username' => VALID_NOT_EMPTY,
'password' => VALID_NOT_EMPTY,
'profile' => VALID_NOT_EMPTY
);
When I tried use custom rules and try to make the validate array check
for uniqueness, my message gets lost. It will keep displaying the
'You need to enter a profile name' error message, not the one I
specify in the validate array. So now I am trying to do some custom
validation, but I don't understand the find() function. I couldn't
find one concrete example of how to use it. I am too much of a
beginner to understand the API that they put out.
I would like to know how to solve my problem both ways. How can I get
the message from the validate function to my view? Also, how can I
write a custom find() statement so I can check if a profile name is
already in the database?
Thanks for your time,
Dave
