Switch Case

[ph8edsicness]

Okay, I'm starting to work with switch cases and was wondering if I define webpages as variables outside of the swith case routine and then call on them depending on the case? I.E.

$content1 = "bio.html" , "r";
$content2 = "news.html" , "r";

switch($content)
{
    case 1
          fopen($content1);
          fclose($content1);
          break;
    case 2
         fopen($content2);
         fclose($content2);
         break;
}

If I'm on the wrong track, any help would be very much appreciated.

// $content is provided via url or form-variable
// maybe it's "news"

switch($content)
{
  case "news": include("news.php");
                        break;
  case "bio": include("bio.php");
                    break;
  default: include("error.php");
}

your code would not work this way, check the manual again

Switches are best used when its something like this

id=8 on the end of a url in the query string

switch($id)
{
case '1':
blah
break;
//etc
case '8':
blah
break;
default:
blah
break;
}

basically the $id is the query and the case '8' is what the query string is equal to.

Okay, if I'm going to link everything to a content.php page and send the variable to the URL to render content.php?id=X (x being the page) what's the easiest way to send the variable? Put it in the <A HREF> tag?

[ahundiak]

Yep on the href question.

[ph8edsicness]

So by utilizting the id=8 method: I'd send the request to the browser via something like:

<A HREF="content.php?id=8">Content 8</A>

?? sorry... newbie... hence the reason it's in this forum hehe

[rIkLuNd]

Exactly!

[ph8edsicness]

Okay, cool... and on the content.php page where the switch case will be do I do this:

switch($id)
{
     case 1
          fopen("url.html" , "r");
          fclose($id);
        break;

 default;
      fopen("error.html" , "r");
 break;
}

[ir4z0r]

nah,

$id = $_GET['id'];
switch($id)
{
     case 1:include("url.html");
        break;

 default:
      include("error.html");
 break;
}

Cool, thanks a lot. Someone told me to use the fopen so I just wanted to make sure they weren't sending me down the wrong path... glad I did. I appreciate the help all. Thanks a bunch!

I'm also going to use a switch case to download files... how would I go about linking it to a video file and forcing the file to be downloaded to hard disk?

[ir4z0r]

easiest way: zip it (recommended for large files)
else:

<a href="download.php?myfile=vfile.avi">Download avi</a>

download.php:

<?PHP
	$filename = $_GET['myfile'];
	$saveasname = basename($filename);
	$filesize = filesize($filename);

header('Content-Type: application/octet-stream');
header('Content-Length: '.filesize($filename));

global $HTTP_USER_AGENT;
if (preg_match('/MSIE 5.5/', $HTTP_USER_AGENT) || preg_match('/MSIE 6.0/', $HTTP_USER_AGENT))
{
	header('Content-Disposition: filename="'.$saveasname.'"');
}
else
{
	header('Content-Disposition: attachment; filename="'.$saveasname.'"');
}
header('Content-Transfer-Encoding: binary');
readfile($filename);
?>

[ph8edsicness]

dude you rule... thanks a lot! Just one question... how do I integrate the the switch case with the download.php page?

[Myrkul]

pardon me for barging in here and interupting.. what exactly is a switch case? I read the manual and i am still a bit confused..

[ir4z0r]

imagine, you have a string variable, which can contain "small", "medium" or "large"

your script has to do certain actions depending on the content of
this variable. You could use

if ($string == "small") ...
else if ($string == "medium") ...
        else ....

That's not too bad, you say? Now think of 20 of these different values!
How much easier is sth of this format:

switch ("string")
{
  case "small": ...; break;
  case "medium": ...; break;
  case "large": ...; break;
}

----------------------------------------------------

<a href="download.php?myfile=2">Download avi</a>

<?PHP
    $filenr = $_GET['myfile'];

switch ($filenr)
{
   case 1: $filename = "files/myvideo.avi"; break;
   case 2: $filename = "files/yourvideo.avi"; break;
   case 3: $filename = "files/hisvideo.avi"; break;
   default: exit;
}

$saveasname = basename($filename);
$filesize = filesize($filename);

header('Content-Type: application/octet-stream');
header('Content-Length: '.filesize($filename));

global $HTTP_USER_AGENT;
if (preg_match('/MSIE 5.5/', $HTTP_USER_AGENT) || preg_match('/MSIE 6.0/', $HTTP_USER_AGENT))
{
    header('Content-Disposition: filename="'.$saveasname.'"');
}
else
{
    header('Content-Disposition: attachment; filename="'.$saveasname.'"');
}
header('Content-Transfer-Encoding: binary');
readfile($filename);
?>

Okay, I have two download.php files.... One in my /video directory and the other in my /audio directory.

The one in the audio directory works perfectly, not a glitch. However when I modified the script and copied it into the /video directory, there's a problem: Instead of downloading the video file, it downloads an HTML Document that reports a parse error.

Since Ir4z0r wrote the script, this is mainly directed towards him.

[ir4z0r]

g

obviously you have made an error when editing the script, hence
read the parse error and try to fix the script in the line given by the error, probably a missing " or ' or ;
