00:00:00,510 --> 00:00:01,170
Welcome back.

2
00:00:01,830 --> 00:00:08,220
Now we have a problem, which is whenever you go to the payment page and there there, there is nothing

3
00:00:08,220 --> 00:00:09,120
to pay for.

4
00:00:09,660 --> 00:00:10,590
You will get an error.

5
00:00:10,590 --> 00:00:12,060
And this is a big, big problem.

6
00:00:12,420 --> 00:00:19,050
And I'm going to assure you of the fix to this problem in the payment that BHP and in any page in your

7
00:00:19,050 --> 00:00:25,050
project, whenever you are echoing something before echoing some something, always.

8
00:00:25,650 --> 00:00:31,200
As a rule of thumb, you need to check whether that thing exists or not.

9
00:00:31,770 --> 00:00:34,020
So here we have two things we are going.

10
00:00:34,080 --> 00:00:37,080
We are echoing the order status and the session total.

11
00:00:37,080 --> 00:00:44,460
So before echoing anything always at this cut, always say is is set.

12
00:00:45,150 --> 00:00:50,280
If is set, get, get and then.

13
00:00:52,220 --> 00:00:52,880
Status.

14
00:00:55,530 --> 00:00:56,190
Status.

15
00:00:57,000 --> 00:00:57,900
Order status.

16
00:01:04,110 --> 00:01:05,670
Then Echo at this point.

17
00:01:05,670 --> 00:01:09,000
We just need to echo this gut.

18
00:01:09,270 --> 00:01:11,550
We just need to echo the order status.

19
00:01:11,940 --> 00:01:14,400
Similarly with this session, we need to say if.

20
00:01:17,330 --> 00:01:18,710
Is said.

21
00:01:19,880 --> 00:01:20,480
Session.

22
00:01:24,440 --> 00:01:26,590
Session two hotel.

23
00:01:28,520 --> 00:01:31,010
Then at this point, we need to echo the decision.

24
00:01:32,670 --> 00:01:34,080
And it's also important.

25
00:01:34,200 --> 00:01:36,900
It's also better to say if it's not empty.

26
00:01:37,380 --> 00:01:39,360
So this is this is going to get the job done.

27
00:01:39,390 --> 00:01:44,640
Also, the button we need to hide the button whenever whenever the session is, is nothing.

28
00:01:45,240 --> 00:01:46,590
We need to hide the.

29
00:01:46,920 --> 00:01:49,350
So we need to say here is.

30
00:01:51,740 --> 00:01:52,670
First BHP.

31
00:01:54,720 --> 00:01:55,920
BHP and then.

32
00:01:58,340 --> 00:01:58,850
If.

33
00:02:01,400 --> 00:02:06,650
Section F is set only a set.

34
00:02:09,610 --> 00:02:10,270
Session.

35
00:02:17,760 --> 00:02:20,940
And then total.

36
00:02:23,260 --> 00:02:24,870
Then we can display this button.

37
00:02:24,880 --> 00:02:33,940
We can here say Caleb Brackett, and then we can say we can close the speech screen and that's it.

38
00:02:33,970 --> 00:02:35,560
This button will only be displayed.

39
00:02:35,560 --> 00:02:38,470
A decision is decision, total is set.

40
00:02:38,980 --> 00:02:46,390
And you can also add other other code if you want to check the order status, for example, if you want

41
00:02:46,390 --> 00:02:52,990
to check the order status if it's set or not, you can also say you can copy this code and you can here

42
00:02:53,020 --> 00:02:58,450
say if order status is set, get.

43
00:03:01,080 --> 00:03:04,950
Your order underscore status.

44
00:03:07,560 --> 00:03:08,220
And then.

45
00:03:08,880 --> 00:03:09,600
And.

46
00:03:12,030 --> 00:03:12,630
And.

47
00:03:14,110 --> 00:03:14,710
Get.

48
00:03:18,320 --> 00:03:18,920
Order.

49
00:03:20,890 --> 00:03:22,300
Order underscore.

50
00:03:23,090 --> 00:03:23,830
Status.

51
00:03:27,510 --> 00:03:29,340
Is equal to.

52
00:03:30,180 --> 00:03:31,200
Not paid.

53
00:03:32,370 --> 00:03:33,270
Not paid.

54
00:03:35,310 --> 00:03:37,200
So at this point, we need to display the important.

55
00:03:37,210 --> 00:03:38,970
Otherwise we shouldn't be displaying the butter.
