1
00:00:00,221 --> 00:00:01,421
You're doing great.

2
00:00:01,421 --> 00:00:06,383
There are four more properties,
two arrays, instructions and tags, and

3
00:00:06,383 --> 00:00:08,601
two strings, yield and source.

4
00:00:08,601 --> 00:00:13,070
Do you have to add getters and
setters for all the properties?

5
00:00:13,070 --> 00:00:15,580
What if you don't care about
doing anything with the property

6
00:00:15,580 --> 00:00:17,150
before it gets set?

7
00:00:17,150 --> 00:00:18,860
Can't we just leave
those properties public?

8
00:00:19,940 --> 00:00:21,120
You could.

9
00:00:21,120 --> 00:00:26,140
However, there are two big reasons why
that's probably not the best option.

10
00:00:26,140 --> 00:00:28,390
First of all, consistency.

11
00:00:28,390 --> 00:00:31,590
Since some of our properties
are accessed through getters and

12
00:00:31,590 --> 00:00:36,710
setters, it's a good idea to access
all properties the same way.

13
00:00:36,710 --> 00:00:41,530
Second, just because there isn't anything
we want to do with the incoming data right

14
00:00:41,530 --> 00:00:46,440
now, that doesn't mean there won't be
something we want to do in the future.

15
00:00:46,440 --> 00:00:47,660
By setting up the getters and

16
00:00:47,660 --> 00:00:52,500
setters now, if we want to do something
with that incoming data in the future,

17
00:00:52,500 --> 00:00:56,130
we won't have to change the way
we interact with the object.

18
00:00:56,130 --> 00:00:58,301
Let's get started.

19
00:00:58,301 --> 00:01:02,640
Back in our recipe class, we'll start by
changing the visibility of the rest of

20
00:01:02,640 --> 00:01:04,861
the properties from public to private.

21
00:01:18,141 --> 00:01:21,490
Now we can add getters and
setters for those properties.

22
00:01:21,490 --> 00:01:24,040
The next one in the list is instructions.

23
00:01:24,040 --> 00:01:27,081
Let's implement this as a single
dimension array of strings.

24
00:01:29,761 --> 00:01:36,301
We'll start with public
function addInstructions.

25
00:01:39,101 --> 00:01:44,201
We'll do addInstruction singular so
we can add our instructions one at a time.

26
00:01:44,201 --> 00:01:46,521
We want to accept a string argument.

27
00:01:51,181 --> 00:01:55,301
Then we can add this new instruction
to our array of instructions.

28
00:02:01,141 --> 00:02:04,490
We also need to add a getter method,

29
00:02:04,490 --> 00:02:09,301
so let's add a public
function getInstructions.

30
00:02:14,001 --> 00:02:19,055
And then we return $this->instructions.

31
00:02:20,980 --> 00:02:24,231
Back in our cookbook file,
let's add and display the instructions.

32
00:02:36,631 --> 00:02:38,611
This is my first instruction.

33
00:02:43,131 --> 00:02:44,191
We'll add another one too.

34
00:02:51,151 --> 00:02:52,891
This is my second instruction.

35
00:02:57,051 --> 00:03:00,311
We can then call an implode
on the get instructions.

36
00:03:04,291 --> 00:03:06,111
We'll separate this with a new line.

37
00:03:16,011 --> 00:03:18,931
Let's change this to recipe1 as well.

38
00:03:18,931 --> 00:03:22,151
Now let's try running our script.

39
00:03:27,431 --> 00:03:31,119
Hm, line five, let's take a look.

40
00:03:31,119 --> 00:03:34,250
We're trying to set our source.

41
00:03:34,250 --> 00:03:35,831
Let's comment out this line.

42
00:03:39,791 --> 00:03:41,191
Line 11 as well.

43
00:03:43,891 --> 00:03:46,250
Great, now we see My First Recipe.

44
00:03:46,250 --> 00:03:48,000
One egg, two cups flour.

45
00:03:49,130 --> 00:03:50,610
This is my first instruction.

46
00:03:50,610 --> 00:03:52,980
And this is my second instruction.

47
00:03:52,980 --> 00:03:54,940
Let's move on to our tags.

48
00:03:54,940 --> 00:03:57,701
Tags are also a single
dimension array of strings.

49
00:03:57,701 --> 00:04:02,381
But I want to make sure that all my
tags are lowercase, so let's add that.

50
00:04:07,141 --> 00:04:12,441
Public function addTag.

51
00:04:19,141 --> 00:04:22,701
Then we're going to set our array tags,

52
00:04:25,641 --> 00:04:29,842
To a strtolower($tag).

53
00:04:31,682 --> 00:04:37,804
And now for our getter,
public function getTags()

54
00:04:40,884 --> 00:04:45,563
return $this->tags.

55
00:04:45,563 --> 00:04:49,764
Let's switch back over to the cookbook and
add some tags.

56
00:05:12,181 --> 00:05:14,323
We can then implode on our tags.

57
00:05:18,603 --> 00:05:20,283
This time we'll separate it with a comma.

58
00:05:25,122 --> 00:05:26,323
getTags().

59
00:05:29,683 --> 00:05:30,510
And run our script.

60
00:05:32,940 --> 00:05:34,410
Great, we see our breakfast and

61
00:05:34,410 --> 00:05:39,100
main course tags added at the end,
and they're lowercase.

62
00:05:39,100 --> 00:05:43,240
All we have left are the two strings,
yield and source.

63
00:05:43,240 --> 00:05:46,761
Let's add both of these
before we test it out.

64
00:05:50,141 --> 00:05:53,969
Since I don't really want to do anything
to yield right now, these will be a basic

65
00:05:53,969 --> 00:05:57,730
getter and setter that will pass
through directly to our property.

66
00:05:57,730 --> 00:06:04,401
So we'll do public function setYield.

67
00:06:04,401 --> 00:06:10,122
We'll pass in the yield and
we'll assign it to our yield property.

68
00:06:18,122 --> 00:06:19,163
We'll also add our getter.

69
00:06:25,843 --> 00:06:27,882
And we return our yield property.

70
00:06:34,523 --> 00:06:37,150
The last property is source.

71
00:06:37,150 --> 00:06:40,505
This will be either a publication or
a person's name.

72
00:06:40,505 --> 00:06:44,650
So title case like we did for the title
seems like a good choice for this too.

73
00:06:44,650 --> 00:06:49,010
Let's add public function setSource.

74
00:06:50,620 --> 00:06:51,601
We'll pass in the source.

75
00:06:54,361 --> 00:06:55,601
And then we'll set our property.

76
00:06:59,521 --> 00:07:03,981
We want to ucwords, or
uppercase words, and pass the source.

77
00:07:07,941 --> 00:07:08,721
Now let's add the getter.

78
00:07:21,621 --> 00:07:24,740
Great, let's go back to our cookbook and
add our yield and our source.

79
00:07:26,740 --> 00:07:29,220
We had our sources up here,
so let's change this.

80
00:07:31,760 --> 00:07:38,131
setSource and setSource.

81
00:07:38,131 --> 00:07:39,471
And then let's add our yield.

82
00:07:51,473 --> 00:07:52,673
setYield.

83
00:07:59,473 --> 00:08:00,513
And then echo.

84
00:08:06,992 --> 00:08:10,353
We also wanna return the source, so echo.

85
00:08:17,713 --> 00:08:18,793
And now let's run our script.

86
00:08:22,072 --> 00:08:24,370
We see our yield and source now too.

87
00:08:25,520 --> 00:08:27,170
We have all the pieces set up.

88
00:08:27,170 --> 00:08:29,980
We're ready to finish
displaying the entire recipe

89
00:08:29,980 --> 00:08:32,200
with a little formatting
to enhance the readability.
