Re: Problem with Math Captcha component @ 1.3.6

I focused on this function:

function validate($data) {
if ($data == $this->Session->read('MathCaptcha.answer')){
return true;
}
}

$data exists
$this->Session->read('MathCaptcha.answer') exists

Why this function does not return 'true' when called from controller
with the following code

if ($this->MathCaptcha->validate($this->data['Contact']
['security_code'])) {
------
}

$this->data['Contact']['security_code'] exists

Thanks :)

Re: $_SESSION contains my data but $Session helper is empty.

Actually, after about a day of mucking around in the core, I solved
the problem. It is just a little "gotcha" with the way Cake loads
start_session(), or so it seems.

I've reproduced the bug with a clean copy of Cake 1.3.6. The reason
why the Session helper fails is only if you have browser output (like
debug output) in the beforeFilter() function of AppController or
anywhere sooner in the dispatching process.

To test, just type some pr() statement in
AppController::beforeFilter(), and then try to reproduce my original
problem above, and you'll see that the Session helper fails. BUT, if
you put something like $this->Session->check('blah') (even if 'blah'
is a nonexistent session key) BEFORE your pr() statement in
beforeFilter(), then the Session helper succeeds.

I believe the reason is because session_start() is not called early
enough in the application, but seems to be called on the first
instance of using the Session component (or helper), and if headers
have already been sent to the browser, session_start() fails. (Though
it is failing silently with my PHP error reporting set to ALL.)

Yuck! I'm glad I solved it though. I've reported issue in Lighthouse.

var $name = 'Contact';
var $useTable = false;

var $_schema = array(

'message' =>array('type' => 'text')
);

var $validate = array(
'name' => array('minLength' => array('rule' =>
array('minLength', 3))),
'email' => array('email' => array('rule' => 'email')),
'subject' => array('notempty' => array('rule'=>'notempty')),
'message' => array('minLength' => array('rule' =>
array('minLength', 60)))
);

}
###########################################################

Controller:
....
var $components = array('RequestHandler', 'Email', 'Session',
'MathCaptcha');

function index() {
$this->set('controller_name', __('Contact',true));
$this->set('action_name', __('Index',true));
if ($this->RequestHandler->isPost()) {
$this->Contact->set($this->data);
if ($this->MathCaptcha->validates($this->data['Contact']
['security_code'])) {
if ($this->Contact->validates()) {
$this->Email->to =
Configure::read('Setting.Site.email') ;
$this->Email->subject = $this->data['Contact']
['subject'];
$this->Email->from = $this->data['Contact']['email'];
$this->Email->send($this->data['Contact']['message']);

}else {
$this->Session->setFlash(__('Please enter the correct
answer to the math question.', true));
}
}
$this->set('mathCaptcha', $this->MathCaptcha-
>generateEquation());
}

######################################################

view

<?php
echo $this->Form->input('name',array('label'=>__('Your
Name',true),'error'=>array('minLength'=>__('You must enter your full
name!',true))));
echo $this->Form-
>input('email',array('error'=>array('email'=>__('Please enter your
valid email!',true))));
echo $this->Form->input('subject',array('options'=>array(null
=>__('-- Choose One --',true),

__('Jobs',true)=>__('Jobs',true),

__('Orders',true)=>__('Orders',true),

__('Products',true)=>__('Products',true),

__('Brands',true)=>__('Brands',true),

__('Services',true)=>__('Services',true),

__('Partners',true)=>__('Partner',true),

__('Promotion',true)=>__('Promotion',true),

__('Other',true)=>__('Other',true)),
'label'=>__('Type of
message',true),

'error'=>array('notempty'=>__('Please choose one',true))));
echo $this->Form-
>input('message',array('type'=>'textarea','label'=>__('Message',true),'error'=>array('minLength'=>__('Your
message is to short!',true))));
echo $form->input('security_code', array('label' => __('Please
Enter the Sum of ',true) . $mathCaptcha));
?>

I detected a problem in the components, function registerAnswer not
work as intended, that does not set the session.

Help me to solve a problem:)

Re: CakePlate - Boilerplate CakePHP distro

Great work.
I also recommend adding something like packages.
Multilingual package
Reports package that will include excel and pdf libs for data export
etc.

Migrating from CakePHP 1.1 - Yikes?!

Hi,

I have a web-application written in CakePHP 1.1 which is non-trivial
and where I was not the original developer. I am just getting back
into this project now and picking it up off the ground.

I am wondering how painful it will be for me to migrate to the latest
version of CakePHP (1.3) ? I realize its a factor of the code
(details), my skills and the needs/longevity of the application - but
whats your gut feeling for a 30000+ LOC typical business app for an
senior engineer (intermediate php developer)?

Maybe I should just limp it along under 1.1?

Thanks.

Retrieving Posts with comments

Hello

i have a simple app that's very similar to the cookbook "Blog"
tutorial

i want to retrieve all Posts having at least one comment.

right now i'm doing this way:

$posts = $this->Post->find("all", array("contain" =>
array("Comment"));
foreach ($posts as $index => $post) {
if (empty($post["Comment"])) unset $posts[$index];
}

is there any way to achieve this by using a single ->find() call?

notes: i'm using Containable.
