Youtube php embed help. Noob Alert!

CEinNYC · October 22, 2010

Hey all -

Below is my code. I'm uncertain how to move correctly code (syntax) what I'm looking to do..

When the user clicks "Next" or "Previous," the following youtube clip will load into the div tag. (With the corresponding description tag). Where do I incorporate the str_replace? And how do I make sure both the youtube clip with the correct description is loaded?

Any advice is appreciated!

<?php

$youtubeIds = array("rHNtuaVHenM","zIAdbIMNq9g","QQ4TlJLa-n4","JccPOA12ELI","JccPOA12ELI", "TWhhXVqVB7E");

$embedCode = '<object width="853" height="505"><param name="movie" value="http://www.youtube.com/watch?v=__YOUTUBE_ID__?fs=1&hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/watch?v=__YOUTUBE_ID__?fs=1&hl=en_US" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="853" height="505"></embed></object>';

if(isset($_GET['youtubeclip']))

{

if(is_numeric($_GET['youtubeclip']))

{

if($_GET['youtubeclip'] >= 0 && $_GET['youtubeclip'] <= 5)

{

$youtubeclip = $_GET['youtubeclip'];

}

else

{

$youtubeclip = 0;

}

else

{

$youtubeclip = 0;

}

$prevyoutubeclip = $youtubeclip-1;

if($prevyoutubeclip < 0)

{

$prevyoutubeclip = 5;

}

$nextyoutubeclip = $youtubeclip+1;

if($nextyoutubeclip > 5)

{

$nextyoutubeclib = 0;

}

$clip_names= array('Episode #1', 'Episode #2', 'Episode #3', 'Episode #4', 'Episode #5', 'Episode #6');

}

?>

Ew that is messy... First, when entering html into a PHP variable, you need to escape all " with a /.

And in forums, use the PHP button (above) when pasting code so we can read it better.

Sooooo....

$embedCode = '<object width="853" height="505"><param name="movie" value="http://www.youtube.com/watch?v=__YOUTUBE_ID__?fs=1&hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/watch?v=__YOUTUBE_ID__?fs=1&hl=en_US" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="853" height="505"></embed></object>';

Would be....

$embedCode = "<object width=/"853/" height=/"505/"><param name=/"movie/" value=/"http://www.youtube.com/watch?v=__YOUTUBE_ID__?fs=1&hl=en_US/"></param><param name=/"allowFullScreen/" value=/"true/"></param><param name=/"allowscriptaccess/" value=/"always/"></param><embed src=/"http://www.youtube.com/watch?v=__YOUTUBE_ID__?fs=1&hl=en_US/" type=/"application/x-shockwave-flash/" allowscriptaccess=/"always/" allowfullscreen=/"true/" width=/"853/" height=/"505/"></embed></object>";

Savagenoob it suppose to be a \ not a / and please use code tags.

Thanks,

Colton Wagner

CEinNYC · October 22, 2010

Okay, will do regarding appropriate syntax. (I should read the rules!)

Thanks for of this...

Sooooo.. How do I incorporate the youtube clip, into the emded code, and have the operation work with the "next" and "previous" buttons? (With the corresponding description tag). I'm sure this is a moronic question regarding accessing arrays but, it's where I am right now.

Thanks again!

Colton.Wagner · October 22, 2010

So basically you did not set your array in the header your code is messed up. I will attempt to change it later I am on my blackberry right now but here is some of it corrected see if it works.

<?php
   $youtubeIds = array("rHNtuaVHenM","zIAdbIMNq9g","QQ4TlJLa-n4","JccPOA12ELI","JccPOA12ELI", "TWhhXVqVB7E");
   $embedCode = '<object width="853" height="505"><param name="movie" value="http://www.youtube.com/v/' . $youtubeIds['$youtubeclip'] .'?fs=1&hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/' . $youtubeIds['$youtubeclip'] .'?fs=1&hl=en_US" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="853" height="505"></embed></object>';

   
   
   if(isset($_GET['youtubeclip']))
   {
   if(is_numeric($_GET['youtubeclip']))
      {
         if($_GET['youtubeclip'] >= 0 && $_GET['youtubeclip'] <= 5)
         {
            $youtubeclip = $_GET['youtubeclip'];
         }
         
         else
         {
            $youtubeclip = 0;
         }      
      }
   else
   {
      $youtubeclip = 0;
   }
   
   $prevyoutubeclip = $youtubeclip-1;
   if($prevyoutubeclip < 0)
   {
      $prevyoutubeclip = 5;
   }
   
   $nextyoutubeclip = $youtubeclip+1;
   if($nextyoutubeclip > 5)
   {
      $nextyoutubeclib = 0;
   }
   
   $clip_names= array('Episode #1', 'Episode #2', 'Episode #3', 'Episode #4', 'Episode #5', 'Episode #6');
   }

Tell me what happens.

Thanks,

CEinNYC · October 22, 2010

Many thanks for your help!

With that change to the embed code, here is the error: Undefined index: $youtubeclip on line 3.

$youtube is defined later in the php. hmmm... mmmm..mmm. Thank you!

Colton.Wagner · October 22, 2010

Did you get it all solved?

Thanks,

Colton Wagner

CEinNYC · October 22, 2010

I did not, rather I got the error: Undefined index: $youtubeclip, on line 3.

Thanks for your help!

CEinNYC · October 23, 2010

bump. still no luck. :wtf:

PaulRyan · October 23, 2010

There are 2 methods that I can think of for this.

1 - Use JavaScript to change the youtube URL's - No page reload

2 - Use PHP with a GET variable from the URL - Requires page reload

If you tell me what sort of thing your looking for I'm sure I could come up with something.

I have made something like this in the past, I used a mix of both to get a good result.

My version also automatically moved to the next song/video when the video had finished and would loop if it had come to the end of the array of songs/videos.

Regards, Paul.

CEinNYC · October 23, 2010

Thanks for this.. ! Below is the link to the site (in progress).

The box on the left has an embedded youtube object code. As the user clicks "next" or "previous" the corresponding video loads. The youtubeIds are in an array, and I assume that I need to use "str_replace," however I am unable to connect the "next/previous" buttons, with both the video description and the youtubeId array.

Because of the restraints of the assignment, I need to keep it solely to php.

Thanks for any advice! I assume there's a small php function that will solve all my problems (in both life and this assignment).

Please excuse the sloppy site. It's in progress.

Link: http://a.parsons.edu/~eckec706/temp/episodes.php

(you may need to click "next" to pull up the first video.. Another issue, but I'll leave that for another time).

Code attached.

So it has to be done in solely PHP, well that should be quite simple to do in theory.

Are the arrays hard-coded or are they dynamic, as in change depending on a variable.

If you give me the array you are working with I will muster something up for you

Regards, Paul.

CEinNYC · October 23, 2010

Thanks! I'll have to pay this forward when I'm a php wiz.

Here's the php.. Note "__YOUTUBE_ID__" is to indicate where to place the .str_replace.

At the end of the php is the html function.

<?php

$youtubeIds = array("rHNtuaVHenM","zIAdbIMNq9g","QQ4TlJLa-n4","JccPOA12ELI","JccPOA12ELI", "TWhhXVqVB7E");

$embedCode = '<object width="640" height="385"><param name="movie" value="http://www.youtube.com/watch?v=__YOUTUBE_ID__?fs=1&hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/watch?v=__YOUTUBE_ID__?fs=1&hl=en_US" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="385"></embed></object>';

if(isset($_GET['youtubeclip']))

{

if(is_numeric($_GET['youtubeclip']))

{

if($_GET['youtubeclip'] >= 0 && $_GET['youtubeclip'] <= 5)

{

$youtubeclip = $_GET['youtubeclip'];

}

else

{

$youtubeclip = 0;

}

else

{

$youtubeclip = 0;

}

$prevyoutubeclip = $youtubeclip-1;

if($prevyoutubeclip < 0)

{

$prevyoutubeclip = 5;

}

$nextyoutubeclip = $youtubeclip+1;

if($nextyoutubeclip > 5)

{

$nextyoutubeclib = 0;

}

$clip_names= array('Episode #1', 'Episode #2', 'Episode #3', 'Episode #4', 'Episode #5', 'Episode #6');

}

?>

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

<?php echo $embedCode ?>

</div>

I have just written the following code for you to use, I have supplied sufficent information and comments.

Now it's up to you to use the script accordingly

<?PHP

  // Function to retrieve data from video information file.
  function getData($string,$oTag,$cTag) {
    $start = strpos($string, $oTag);
    $end   = strpos($string, $cTag, ($start + strlen($oTag)));
    $start = ($start + strlen($oTag));
    $end   = ($end - $start);

    return substr($string, $start, $end);
  }

  // Function to get and set information about the current episode
  function currentEpisode($youtubeURL) {
    $stats = 'http://gdata.youtube.com/feeds/api/videos/'.$youtubeURL;
    $stats = file_get_contents($stats);

    $videoURL = 'http://www.youtube.com/v/'.$youtubeURL;
    $videoDes = getData($stats,"<media:description type='plain'>","</media:description>");
    $videoTtl = getData($stats,"<title type='text'>","</title>");

    $information = array("title"=>$videoTtl, "description"=>$videoDes, "URL"=>$videoURL);
    return $information;
  }

  // Function to set the next link
  function nextLink($num,$count) {
    if($num == $count) {
      $nextLink = 1;
    } else if($num+1 > $count) {
      $nextLink = 1;
    } else {
      $nextLink = $num+1;
    }
    return $nextLink;
  }

  // Function to set the previous link
  function prevLink($num) {
    if($num-1 <= 1) {
      $prevLink = 1;
    } else {
      $prevLink = $num-1;
    }
    return $prevLink;
  }

  // Place episodes in an array
  $episodes = array("1"=>"rHNtuaVHenM","zIAdbIMNq9g","QQ4TlJLa-n4","JccPOA12ELI","JccPOA12ELI", "TWhhXVqVB7E");

  // Count the number of episode
  $countEpisodes = count($episodes);

    // If $_GET['episode'] is a number we'll set the variable, otherwise set as first episode.
    if(is_numeric($_GET['episode'])) {
      $currentEpisode = $_GET['episode'];
    } else {
      $currentEpisode = 1;
    }

    // If the current episode number is greater than episode count, set episode as last.
    if($currentEpisode > $countEpisodes) {
      $currentEpisode = $countEpisodes;
    }

    // If the current episode mumber is less than 1, set the episode as 1
    if($currentEpisode < 1) {
      $currentEpisode = 1;
    }

  $nextLink = '<input onClick="window.location=\'?episode='. nextLink($currentEpisode,$countEpisodes) .'\';" type="button" name="next" value=">>">';
  $prevLink = '<input onClick="window.location=\'?episode='. prevLink($currentEpisode)                .'\';" type="button" name="prev" value="<<">';

  // Get the information for current episode selected
  $thisEpisode = currentEpisode($episodes[$currentEpisode]);
  // Set the episode URL for embed
  $thisURL = $thisEpisode['URL'];
  // Set the episode description
  $thisDes = nl2br($thisEpisode['description']);
  // Set the episode title
  $thisTtl = $thisEpisode['title'];
  
  echo '<pre>';
  print_r($thisEpisode);
  echo '</pre>';

  echo $prevLink;
  echo $nextLink;
?>

Tell me how you get on with it.

Regards, Paul.

CEinNYC · October 23, 2010

Thanks so much for this. I'll take a good look through and figure out what's going.. (Upon initially looking, there's lots of new "Stuff" there for me to learn). I'll let you know how it goes.

Thanks!
