In this video, we will create a second child while we look at more ways to override methods.
Siblings
We cannot call a private property of a parent directly. We have to make sure we call the parent getter when overriding a method in a child or we may hit an infinite loop.
public function getTitle()
{
return '<strike>' . parent::getTitle() . '</strike>';
}
We have our second child, ListingInactive.
0:00
For this class we're going
to rewrite the get method so
0:03
that the only data we return
is the title and status.
0:07
We also want to update the status
like we did for ListingPremium, so
0:11
let's start there.
0:15
Protected $status = 'inactive',
0:21
now we're ready to override our getters,
0:26
public function getWebsite(), and
0:32
we're just going to return nothing.
0:38
We'll do the same thing for
email and Twitter.
0:46
For the title,
1:01
instead of just returning the title, let's
return the title with a strikethrough.
1:02
We can't access the title directly,
and since we're rewriting getTitle,
1:26
if we try to call this getTitle
we'll hit an infinite loop.
1:32
We could change the visibility
of the property, but
1:37
that's not really what we want to do.
1:39
Instead, we'll call the parent
method just like we did
1:41
when we extended the set values.
1:44
GetTitle, now we need
our collection to use
1:50
this new class, open classes, Collection.
1:55
We've already been using the inactive
status just not given it its own class, so
2:01
we don't need to update the statuses.
2:06
The ad listing method determines
which listing class we use.
2:08
Let's add another conditional.
2:17
If the status is inactive,
2:27
then we use the inactive class.
2:33
Let's preview this in the browser.
2:40
If we choose Inactive we now see
that our title is crossed out and
2:43
we don't have any other details,
but let's update the display.
2:49
Case inactive.
2:59
Great.
