Help needed dynamically creating web pages

[MATLAB]

I have not created any code for this as I dont know where to start, or what its even called. I am on about trying to create a page dynamically depending on the id which is selected.

 

Parts of the URL will change depending on what id is selected for example: 'http://www.facebook.com/home.php?sk=h.

 

i am wanting to create a video website, where when the thumbnail of a video is clicked, a new page is loaded with that more details of the video and the video itself, and im guessing the url would change to identify the id of the video.

 

I cannot create a page for every video by hand, as i will have many videos and this is not very efficient.

 

I am just after the name of this technique or a pointer to a tutorial for how to achieve this.

 

Thanks,

Matlab

You are talking about the "Query String". Everything after the ? in the url is a query string that provides parameters to your script. You get a "super-global" array called $_GET.  In your example:

http://www.facebook.com/home.php?sk=h

$_GET['sk'] would contain the value 'h'. Multiple values can be provided by separating them with an ampersand ('&')

http://www.facebook.com/home.php?sk=h&id=123

In this case $_GET['sk'] is 'h' and $_GET['id'] is 123.

 

Your script can make decisions based on the values in the $_GET array.

Thanks!

 

Would it be a simple if statement so if the value of $_GET = "h" then echo this e.t.c?

do it something like this

 

$_sk = isset($_REQUESt['sk']) ? $_REQUEST['sk'] : '';

$_id = isset($_REQUEST['id']) ? $_REQUEST['id'] : '';

switch ($_sk) {

default:

// the main page of the website

break;

 

case vid:

// selected video page..

 

select * from table where id = $_id

 

echo html here... or stop PHP display HTML with php elements added into it, and then restart PHP...

break;

}

thanks a lot. Do you know what this concept is called so i can look at it in more detail please?

will get you started with the switch...  i think it makes for easier reading down the road...  not as many if elseif elseif elseif elseif else statements needed (if any at all).
