Returning MySQL data to cakephp view - cakephp

Question

I am pretty new to cakephp and I am banging my head against the wall trying to write a pretty basic statement.
In my view file, I want to say if the is_open column in the events table is true, echo something. If it is not true, echo something else.
<?php
if ($response['data']['Event']['is_open'] == true) {
echo "Yes";
} else {
echo "No";
}
?>
I am having trouble working backwards within the controller to get the data in the first place.
In my controller I have something this:
public function some_function() {
$events = $this->Event->find('all');
}
In my view file, I get this error:
Notice (8): Undefined index: Event [View/Applications/agreement.ctp, line 21]
Can anyone point out what I am doing wrong?
I have been going through the blog tutorial and it's clear in some places to me and not clear in others. Where I am still having trouble is displaying anything in the view.
After further reading I want to do something like this in the controller:
$myVariable = $this->Event->find('first',
array( 'fields' => 'Event.is_open ',
'conditions' => array('Event.id =' => '400') ));
What I am hoping to say is grab the is_open value from the events table where the events.id = 400 (later on this value will be dynamic) Does this look even remotely correct? – mmalv just now edit

How did you come up with $response['data']?
In your EventsController you correctly set the return of $this->Event->find('all') to $events. In order for this variable to be available to your view you need to call Controller::set on it like this:
$this->set('events', $events);
Or even simpler, in one step, you can just do:
$this->set('events', $this->Event->find('all'));
Then in your Event view (perhaps someplace like View/Events/index.ctp) access the variable by the name $events. It should be in the format
Array(
[0] => Array(
'Event' => Array(
'id' => 1,
'name' => 'An open name!',
'is_open' => true
)
),
[1] => Array(
'Event' => Array(
'id' => 1,
'name' => 'Another event but closed',
'is_open' => false
)
)
)
So now all you need in your view is to run a loop like:
foreach ($events as $key => $value) {
if ($value['Event']['is_open']) {
echo "Yes";
} else {
echo "No";
}
}
All this is thoroughly explained in the cookbook, just go through the blog tutorial.
