| 0:00 | This is a short tutorial on how to embed Php code inside HTML code. This is very useful in many situations. |
| 0:14 | For example if I were to create Php tags and echo out my name here. |
| 0:23 | By running this , let's click on a file, we just get an Alex. |
| 0:30 | Now for example, I can embed HTML inside this and echo it out here to make Alex a little bolder. |
| 0:38 | But what I can do is I can switch this the other way round. |
| 0:45 | Let's start again, create an HTML page. I'm going to use this example |
| 0:52 | I will start a Php and a tag here. I echo out Alex and then come in 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 | Lets 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 embed 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 a n 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's 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 |
