My code wont work:

[Guest MrLeN]

I am trying to get the username of the channel that clicks to my website from their YouTube homepage:

 

if (isset($_SERVER['HTTP_REFERER'])) {
echo '...<br />';
echo ''.$_SERVER['HTTP_REFERER'].'<br />';
echo '...<br />';
$url = $_SERVER['HTTP_REFERER'];
$url_parts = parse_url($url);
$path_parts = explode('/', $url_parts['path']);
foreach ($path_parts as $pp) {
if ($path_parts[0] == 'user') {
  $user = $path_parts[1];
} else {
  $user = $path_parts[0];
}
  $user = $pp;
  break;
}
}
echo 'username: '.$user.'';
exit;

 

..but it doesn't echo a username.

 

I can't work out why.

 

Can someone help me?

[trq]

In English please?

I am trying to get the username of the channel that clicks to my website [ie: user ID out of the http_referrer] from their YouTube homepage:

[ManiacDan]

There's a fatal syntax error in this code, perhaps that's causing it.

 

Also, you'll need to debug this on your own.  You can't just write an entire program and hit "go" and then give us "when I hit go nothing goes."  Does the referrer come in properly?  Does the explode produce the data you'd expect?  Are you sure you know what foreach does?  What happens when you remove that (completely unnecessary) break statement?

[Guest MrLeN]

Well, I don't know the answer to any of those questions. Because someone helped me with the code in MSN messenger, and now he is gone.

 

All I want to do is detect the YouTube username of the YouTube channel -- for if someone clicks from that channel to my website.

 

I don't understand much of the code above.

[Guest MrLeN]

The code doesn't display any errors.

 

It simply displays:

 

...

http://www.youtube.com/user/USERNAME?feature=mhee

...

username:

[Guest MrLeN]

ie: the part after username: doesn't display a username.

 

If I can just get the username to display, I know how to fwrite it to a text file (which is the text file you helped me with before thorpe).

Change this

$path_parts = explode('/', $url_parts['path']);
foreach ($path_parts as $pp) {

 

To

$path_parts = explode('/', $url_parts['path']);
print_r($path_parts);
foreach ($path_parts as $pp) {

 

And tell us what you see.

[Guest MrLeN]

It returns:

 

...
http://www.youtube.com/user/MyYouTubeUserName?feature=mhee
...
Array ( [0] => [1] => user [2] => MyYouTubeUserName) username: 

[Jessica]

So do you see now why your code doesn't work?

[Guest MrLeN]

No, I am sorry, I don't 

[Jessica]

This is your code

if ($path_parts[0] == 'user') {
  $user = $path_parts[1];
} else {
  $user = $path_parts[0];
}

 

This is $path_parts

...
http://www.youtube.com/user/MyYouTubeUserName?feature=mhee
...
Array ( [0] => [1] => user [2] => MyYouTubeUserName) username: 

 

 

(You also have that section looping in a foreach which is not needed)

[Guest MrLeN]

This is your code

if ($path_parts[0] == 'user') {
  $user = $path_parts[1];
} else {
  $user = $path_parts[0];
}

 

This is $path_parts

...
http://www.youtube.com/user/MyYouTubeUserName?feature=mhee
...
Array ( [0] => [1] => user [2] => MyYouTubeUserName) username: 

 

 

(You also have that section looping in a foreach which is not needed)

 

I really don't understand.

 

I am trying to work out what you are pointing out, but I have no clue.

[Jessica]

You are looking is $path_parts[0] == 'user'. It isn't. So your code says $path_parts[0] must be the username.

[Guest MrLeN]

So I have to echo $path_parts[0] ?

[Guest MrLeN]

Oh, the numbers are wrong?

 

[1] and [0]

 

should be

 

[1] and [2]

 

?

[Guest MrLeN]

I know that the reason this code is in there:

 

if ($path_parts[0] == 'user') {
  $user = $path_parts[1];
} else {
  $user = $path_parts[0];
}

 

..is because sometimes the YouTube URL has /user/ in it, and sometimes it doesn't.

 

That is why there are two different variations.

[Jessica]

But path_parts[0] is NEVER going to be 'user'.

 

 

[Guest MrLeN]

Why not?

[Jessica]

I give up.

[Guest MrLeN]

I give up.

 

I know you're frustrated, but I sat here for a long time trying to figure out why you are saying what you are saying.

 

I don't get it. I'll agree that I look like an idiot, if that makes you feel better.

 

I have no idea what you are saying, or why. I am trying to understand.

[Guest MrLeN]

Ok, I give upo too. It's 1:37am. I need to go to sleep.

[Jessica]

Oh, the numbers are wrong?

[1] and [0]

should be 

[1] and [2]

 

That was correct, I don't know what you are still confused about. Did you change it? If so post the updated code. Remove that section from the foreach.

If you want it coded for you, I suggest the Freelancer's forum.

 

If you want to learn PHP, I think you need to take a few steps back, because what you're trying to do seems way beyond your current abilities or knowledge of the language.
