| 00:00 | Here is a tip for displaying HTML inside your php. This is specially useful when you are using ‘if’ statements or anything that uses a block and when you need to do this on a condition or you need to output a lot of HTML inside something that is working on php. |
| 00:23 | In this example, I’ve got a variable- name and this is set to "alex". |
| 00:30 | So, if I type- $name equals alex then it will echo out “Hi, Alex”. |
| 00:36 | If $name is not equal to "Alex" - so we type else- we will echo out “You are not Alex. Please type your name”. |
| 00:47 | And we have an input field here which should have a form around it. |
| 00:53 | So, form action equals 'Index.php'
method = 'POST' and we end the form here. |
| 01:05 | We can bring this down a bit so that it looks better. So, we have some HTML code inside this else block . |
| 01:15 | So we type ‘If else’ and we have got a block starting here and a block ending here. And what could be a lot of HTML code. |
| 01:27 | The purpose of this tutorial is to show you that you don’t need to use echo and echo out HTML code. |
| 01:34 | It’s easier and saves time when you want to code using quotation marks rather than single inverted commas. |
| 01:41 | Also it’s nicer to have a code inside the blocks, say, this block here without having to worry about what you are typing. |
| 01:58 | So, if you are used to quotation marks this forward slash will escape the character. |
| 02:08 | So, it will be displayed but will be ignored as the end of the echo and the beginning of this echo here. |
| 02:20 | For example: let’s just refresh. |
| 02:25 | Since name equals "Alex", it is greeting me as we saw earlier. |
| 02:31 | The echo is okay for a small amount of text but for a large amount with a form etc, we don’t want the echo. |
| 02:44 | As it stands at present, it won't run. We will receive an error. We haven't provided a method of output for this text. |
| 02:59 | That’s on line 12. So, if you go to line 12, you will see that it's here. We can rectify the problem in this way. |
| 03:09 | We have our php opening tag here and I am going to end the tag down here. |
| 03:16 | So, we are ending the tag after the block starts. Now, I will start a new tag just before the flower brackets or curly bracket here. |
| 03:31 | So now we have a chunk of php code here and a chunk here. And the rest here is not interpreted as php. Since it is HTML it will be displayed as HTML code. |
| 03:49 | So, what I am going to do first is, change all these to quotation marks. |
| 03:56 | If you implement this method from the beginning, you could code easily and it would work a lot better. |
| 04:08 | So, once again as is visible on the screen we have a block here and the block here. It may appear as though the php would end here |
| 04:22 | but we have not ended a block inside here, in this area but we are going down here. We aren’t echoing out but displaying this. |
| 04:37 | This applies specifically to the else block. We end the block in the blue highlighted line here and here. |
| 04:47 | So again, we will first get “Hi, Alex”. Now if we change the name to let’s say "Kyle", refresh. |
| 05:01 | You will see that the HTML has been displayed properly. But it hasn’t been echoed out using php. |
| 05:09 | This is a good method to use when you want to display HTML properly and read it easily. Hope this tutorial has been helpful .Thank you for watching. |
