| 00:00 | This is a short tutorial on how to embed Php code inside HTML code. This is very useful in many situations. |
| 00:14 | For example, if I were to create Php tags and echo out my name here. |
| 00:23 | By running this, let's click on a file, we just get "Alex". |
| 00:30 | Now for example, I can embed HTML inside this and echo it out here to make "Alex" a little bolder. |
| 00:38 | But what I can do is I can switch this the other way round. |
| 00:45 | Let's start again, create an HTML page. I'm going to use this example. |
| 00:52 | I will start a Php and a tag here. I echo out "Alex" and then coming outside the Php tags and add my bold() here and my bold end() after the ending Php tag. |
| 01:13 | And it gives us the same result, nothing has changed even though I've refreshed the page. |
| 01:20 | So, we can change that to underline() and you can see that "Alex" is underlined. |
| 01:26 | So, we can do it either ways. It's up to you to use the HTML code inside the echo or not. But there are more uses to this. |
| 01:39 | Now, if you do know HTML, you know the input tag is a template tag. |
| 01:48 | So, let's say 'text' and the name of this will be 'name' and the value is going to be equal to 'Alex'. |
| 01:56 | Let's refresh this and we see we've got a text box here with "Alex" inside. Now I want to use Php to grab the get variable header and put it inside this value of our input value. |
| 02:14 | Now, this is really useful in some cases like form submission and error checking where you want the posted variables to stay inside the value of each text box. |
| 02:30 | If you haven't seen the GET tutorial already, make sure you watch that. |
| 02:38 | Now, bring this down a couple of lines, obviously we still run this code successfully because it works on similar line basis. |
| 02:48 | So, this you see here is exactly the same as that, you just have to force it down a bit and I'm going to create Php text here. |
| 02:58 | This is going to look a funny brown colour because we're working in Php highlighting and it's not really recognizing this type of highlighting. |
| 03:08 | Ok, I'm just going to echo out "Alex". |
| 03:12 | Since this works on a single line basis, bring this all up on a single line. So, now I have embedded this inside that and your embedding is done. |
| 03:25 | By refreshing we get the value of "Alex". We're echoing out now Php inside an HTML value. |
| 03:35 | So, we're using Php code inside our value here. |
| 03:40 | I'm going to demonstrate dollar ($) underscore (_) GET, remember using the single quotes. |
| 03:50 | I'm going to say 'name' and then refresh. |
| 03:55 | Nothing has happened; so type in name=alex which gives us "alex" inside that. |
| 04:04 | Type in name=kyle. It gives us "kyle" inside that. |
| 04:11 | Basically you can embed any Php code you want inside that. |
| 04:16 | Try saying echo Php info() and you'd get a very funny result. |
| 04:28 | This is the HTML code of Php info document. |
| 04:33 | So, you can see that there's loads of code in that. |
| 04:37 | Here we're just working with Php inside. The only thing you need to worry about is being careful with your single and double quotes. |
| 04:46 | So this was the basic tutorial on embedding Php code inside HTML code. |
| 04:53 | I hope it was useful. Thanks for watching. |
