PHP, Switches, Includes...... oh the not so fun

[Kezzer]

Ok so i've been running around in circles trying to sort this problem. I've got the answer but i don't understand it. So what i wanted to do is use the article.php file to include other files which would display certain information from the database. For example http://www.kezzer.co.uk/article.php?page=photoshop

Ok easy enough, no problems there. So how about catching the URL and getting it to display the information from the database? http://www.kezzer.co.uk/article.php?...D=2&category=3

That wouldn't work because of the switch. So the following code was given to me to overcome this:

This is a testfile.<br>
<?php
if(isset($_GET['id'])){
echo 'ID: '.$_GET[.'id'].'<br>';
}else{
echo 'No ID is set.<br>';
}
if(isset($_GET['category'])){
echo 'CATEGORY: '.$_GET['category'].'<br>';
}else{
echo 'No CATEGORY is set.<br>';
}
?>
<br><br>

I don't understand what i'm doing. My switch is so simple, it just defines the URL which is caught and tells it which file to pick up. Apparently the method given to me as the example above states is an advanced method of accomplishing what i want to do.

Any help would be ever so nice

The code is pretty simple if you break it down. PHP usualy looks scarey when its in one big block

This is the same as what you already have, just commented.

This is a testfile.<br> 

<?php
// start the PHP
 
if(isset($_GET['id'])){ 

// If the variable "id" has been set via the GET method of submition (ie, its in the URL of the page) then do the following :

echo 'ID: '.$_GET[.'id'].'<br>'; 

//echo "ID :" then print the Variable value, and start a new line

}else{ 

// If the variable id hasnt been set, do this :


echo 'No ID is set.<br>'; 

// print "No ID is set" and start a new line

}

// end the IF loop

 
if(isset($_GET['category'])){ 

// If the variable "'category'" has been set via the GET method of submition (ie, its in the URL of the page) then do the following :

echo 'CATEGORY: '.$_GET['category'].'<br>'; 

//echo "CATEGORY :" then print the Variable value, and start a new line

}else{ 

// If the variable 'category' hasnt been set, do this :

echo 'No CATEGORY is set.<br>'; 

// print "No CATEGORY is set" and start a new line

} 

// End the IF loop.

//End the PHP code block
?> 
<br><br>

Hopefully thats a little bit of help

Indeed that does

So i still use my switch, but to display the data i use that code?
