1
00:00:00,420 --> 00:00:02,500
Okay, we're starting to get somewhere.

2
00:00:02,500 --> 00:00:06,670
Now I want to be able to pull only
the recipes with a particular tag.

3
00:00:07,700 --> 00:00:09,535
Let's go back to our recipe collection.

4
00:00:15,995 --> 00:00:19,215
We'll create a new method
called filterByTag.

5
00:00:25,274 --> 00:00:30,455
We'll pass in the value of
the tag that we want to look for.

6
00:00:30,455 --> 00:00:33,935
We'll initialize a new
taggedRecipes array.

7
00:00:40,195 --> 00:00:43,435
Then we can loop through the recipes and
look for our tag.

8
00:00:55,515 --> 00:01:02,895
We can use if in_array, we're going to
make sure that our tag is lowercase.

9
00:01:02,895 --> 00:01:04,335
We use strtolower.

10
00:01:06,394 --> 00:01:07,314
And our tag.

11
00:01:09,415 --> 00:01:12,394
Then we'll be looking
in the recipe getTags.

12
00:01:17,354 --> 00:01:21,495
If we find the tag, we'll add
this recipe to our taggedRecipes.

13
00:01:33,715 --> 00:01:36,675
Finally, we'll return our taggedRecipes.

14
00:01:39,655 --> 00:01:42,355
Let's go back to our cookbook and
use our new filter.

15
00:01:45,295 --> 00:01:48,715
I'm going to create
a new recipe collection.

16
00:01:48,715 --> 00:01:52,154
This is going to be for
any recipe tagged breakfast.

17
00:02:08,475 --> 00:02:15,395
Then we can loop through the breakfast
recipes after we filter by tag.

18
00:02:15,395 --> 00:02:16,415
Here's our filter.

19
00:02:20,775 --> 00:02:22,044
And we pass it breakfast.

20
00:02:24,984 --> 00:02:27,604
Then we'll return each of these as recipe.

21
00:02:31,684 --> 00:02:35,384
Then we're going to add this recipe
to our breakfast collection.

22
00:02:43,823 --> 00:02:46,244
Now let's render our
breakfast recipes instead.

23
00:02:55,244 --> 00:02:59,060
Now we see just the recipes
that were tagged as breakfast.

24
00:02:59,060 --> 00:03:02,290
There's one more feature that I'd
like to see for our collection.

25
00:03:02,290 --> 00:03:03,660
A shopping list.

26
00:03:03,660 --> 00:03:05,440
We'll dive into that in the next video.
