Re: Best Practices: Toggle Item In Element
Check the example at http://www.php.net/manual/en/function.empty.php#id7108863 Basically isset() checks whether a variable has been set at all, no matter the value, while empty() considers the following all to mean empty: (an empty string) 0 (0 as an integer) 0 (0 as a string) NULL FALSE array() (an empty array) var $var; (a variable declared, but without a value in a class) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Cake PHP group.

One mistake - isset() also returns false if the variable is set to null. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Cake PHP group.

Re: Best Practices: Toggle Item In Element
Actually both seemed to work for me. Thanks to you both. Anyone know the difference, out of curiousity?

Best Practices: Toggle Item In Element
Ok so I have a bunch of views, called by different controllers that
each reference the same element 'post'. Each controller passes a set
of parameters to the element via the renderElement('post', $data)
method. All the parameters are passed through $data and all is peachy.
However, ONE of the views has a special little parameter called
'ticker' passed through $data['ticker']. In my view I have set
$data['ticker'] = 1 to indicate that the little ticker should be shown
in the element only for this one view!
In my 'post' element I say:
if ($data['ticker']){
// show that ticker!!!
}
Problem is that for ALL the other controllers-views I get a 'missing
index' for ticker. So, what I am asking is what is the best php5 /
cake practice for handling this. I would rather not have to define
$data['ticker'] in every other view or anywhere else. Is there a way
to define it in the element and then overwrite it on load (or
something). I am trying to determine the best, most agile practice for
this situation.
