hello everybody,
I have a problem using criteria and unset function.
Issue is : whane I use cirteria in a function a a parameter and I use unset on that criteria in this function, when I exit function this criteria is empty.

first I call the function with my criteria

$eta_handler->getObjectWithJoin($criteria);

then I use unset in that function

function getObjectWithJoin( $criteria ){

.....

if (!empty($criteria->criteriaElements))
{
.....
foreach ($criteria->criteriaElements as $indice=>$criteriaElement)
{
...
unset($criteria->criteriaElements[$indice-$indice_eval]);
...
}

...

}

}


than I call my function a second time with my criteria
$eta_handler->getObjectWithJoin($criteria);

But this time criteriaElements is empty


I tried with a copy ($criteria2 = criteria) for the second call but I had same result.


Does anybody could explain me what happens or has an idea to have my criteria not empty i nthe second call of my function ?

thanks for that.

Why do you do the unset, if you don't want it to be cleared?
Can you tell us, what is the purpose of your handler. It seems to gather information from two tables and in some repetive manner?

You could use

or

hey, thank you for your but this wasn't the problem.
In fact I've found the answer :
instead of doing a copy like this :
$citeria2 = $criteria
I use the clone() function like this:
$criteria2 = clone($criteria)

but I still don't know why $criteria used in my fonction is not a copy of $criteria but is a reference...
