hi all,
i read a post in here about having a login form built into the default
layout. it suggested using an element, so i created one. i'm having
one small problem with variables, and i'm hoping someone can help me
out. what i'm trying to accomplish, is having the login form in the
right column...but, after they login, i want to replace the form with
a logout button. so, i figured the default layout would be the best
place for this logic.
ok...here's the login element :
<?php if (isset($error) && $error): ?>
<p><div class="error_message">Incorrect <br/>Username/Password</div></
p>
<?php endif; ?>
<h1>Login/Register</h1>
<form class="loginform" action="<?php echo $html->url('/users/
login'); ?>" method="post">
<p>
Username<br/>
<?php echo $html->input('User/username', array('id' =>
'user_username', 'size' => '40', 'class' => 'textbox')) ?>
<?php echo $html->tagErrorMsg('User/username', 'Username
required') ?>
</p>
<p>
Password<br/>
<?php echo $html->input('User/passwd', array('id' =>
'user_passwd', 'size' => '40', 'type'=>"password", 'class' =>
'textbox')) ?>
<?php echo $html->tagErrorMsg('User/passwd', 'Password required') ?
>
</p>
<p><?php echo $html->checkbox("User/cookie");?> Remember
Me<br/></p>
<p><input class="button" type="submit" value="Login" /></p>
<p>
<br/>
[<a href="#">Forgot Password?</a>]<br>
Not Registered? <a href="#">Sign Up!</a>
</p>
</form>
the 'error' variable is being passed from the login function in my
users controller...
function login()
{
$this->set('error', false);
if(isset($this->params['data']))
{
if ($this->params['data']['User']['username']=='')
{
$this->User->invalidate('username');
}
else if ($this->params['data']['User']['passwd']=='')
{
$this->User->invalidate('passwd');
}
else
{
$this->set('error', true);
}
$auth_num = $this->othAuth->login($this->params['data']
['User']);
$this->set('auth_msg', $this->othAuth->getMsg($auth_num));
}
}
and, here is the call from my default.thtml:
<?php echo $this->renderElement("login",array("error"=>$error)); ?>
my problem is, i get an 'undefined variable : error' if the page is
loaded from anywhere but the login function. i understand why this is
happening, but i'm not sure how to fix it. i tried using isset above
the call to renderElement, to try and set the variable to false if
it's not valid, but it won't let me do that...and, i think that's not
the right way anyway.
can someone point me in the right direction to do this.
thanks
