Using $_GET

[adamking217]

I cannot seem to get my link to work.. I want to build a php script that has more than one $_GET command.. The link I want to make is: index.php?section=tutorial&viewing=18-classes_or_ids.

Here is my PHP code..

 

<?php
$section = $_GET['section'];
switch ($section)
{
case "home":
include("home.html");
break;
case "register":
include("register.html");
break;
case "tutorial_home":
include("tutorial.html");
break;
default:
include("home.html");
}
$tutorial = "?section=" .  urlencode('tutorial&viewing') . $_GET['tutorial&viewing'];
switch ($tutorial)
{
case "18-classes_or_ids":
include("classesorids.html");
break;
}
?>

 

Please help me!!

You've got your GET tags correct.

 

$section = $_GET['section'];
$viewing = $_GET['viewing'];

 

Didn't really, know what you wanted to accomplish...

Hi there adamKing217,

 

The way as you have constructed your links means that to access $_GET information, you would need to look at how you have done the link:-

 

index.php?section=tutorial&viewing=18-classes_or_ids.

 

The bits I have highlighted are the pieces available in the $_GET array when the link is sent to the browser (at least this is how I understand it to be)  If you did print_r($_GET); on your page when the link was sent you would see the parts highlighted available from the array to use, this is where the use of isset() is paramount as a form/processing handler.

 

So in your link $_GET would be this (set variables):-

 

$_GET['section'] => tutorial

$_GET['viewing'] => 18-classes_or_ids

 

Also when constructing links, the & needs to be made into & for validation purposes if you are into that sort of stuff.

 

$tutorial = strip_tags($_GET['viewing']);//gives you that extra added security
switch ($tutorial){
case "18-classes_or_ids":
   include("classesorids.html");
break;
}

 

And also for this:-

 

<?php
$section = strip_tags($_GET['section']);//added security
switch ($section){

 

I have added the strip_tags() function so that you can have a safer script, I think that it is prudent to always be thinking of security, but that'a just my opinion.

 

Cheers,
