| 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 codes 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 displaced 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 re- read easily. Hope this tutorial has been helpful .Thank you for watching. |
