PHP - How To Detect An Upload From Youtube?

hello,
I am trying to figure out how I can take only the v= in the youtube urls

http://www.youtube.com/watch?v=nGawAhRjtoA&feature=topvideos

i just want php to take v=nGawAhRjtoA and ignore everything else

any ideas guys/gals?

thanks

The application that I want to build is quite simple. Here is a bit of the background of the work flow:

In my company, we create video for our client profile. After the video is done, we upload the video to our website and to youtube. It is done automatically.

After a period of time, the client can delete the video. Of course, it will delete the video in our system as well as the video in youtube. For now, the video in our system is deleted automatically. However, youtube video is deleted manually.

Our company has grown to have quite a lot of clients. It's hard for us to keep track clients that requested to delete their videos. We want to be able to have an application that will delete youtube video automatically.

I already tried to play around with youtube authentication in http://code.google.com/apis/youtube/2.0/developers_guide_php.html#Authentication but I have no luck with the authentication.

I want the application to be able to delete the video under my youtube account without having me to login to youtube. In my case right now, every time the application wants to delete the video, I have to send the request to youtube and ask for verification (i.e. I have to do application verification every time).

Here is what I have done so far:


ini_set('display_errors', 1);
ini_set('log_errors', 1);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
error_reporting(E_ALL);

This is how I call the function: http://example.com/youtube_delete_video.php

So, what I need basically is to know
1. how can I store the authentication after I verify it from youtube?
2. What function to populate after I store the authentication? <- I couldn't figure where this part is in the documentation.

PS: example.com is not a real url. It's just for the sake of writing the post he )

Hi,

I'm working with the YouTube API to echo a feed based on a user's query.

My current code is below.  With this code, a whole list of videos is retrieved.

However, in order to present the feed as I wish to... I need to return each video in the feed individually. 

I am unsure how to do this and any advice would be really appreciated.

Code: [Select]
$feedURL = "http://gdata.youtube.com/feeds/api/videos/-/$youtubeQuery?orderby=viewCount&max-results=10";
               
          // read feed into SimpleXML object
          $sxml = simplexml_load_file($feedURL);
 
          // iterate over entries in resultset
          // print each entry's details

          foreach ($sxml->entry as $entry) {
          // get nodes in media: namespace for media information
          $media = $entry->children('http://search.yahoo.com/mrss/');
                 
          // get video player URL
          $attrs = $media->group->player->attributes();
          $watch = $attrs['url'];
                 
          // get video thumbnail
          $attrs = $media->group->thumbnail[0]->attributes();
          $thumbnail = $attrs['url'];
                 
          // get <yt:duration> node for video length
          $yt = $media->children('http://gdata.youtube.com/schemas/2007');
          $attrs = $yt->duration->attributes();
          $length = $attrs['seconds'];

          // get video title
          $title = $media->group->title;
                 
          // get <gd:rating> node for video ratings
          $gd = $entry->children('http://schemas.google.com/g/2005');
          if ($gd->rating) {
          $attrs = $gd->rating->attributes();
          $rating = $attrs['average'];
          } else {
          $rating = 0;
          }
           
          }
          ?>

Youtube has an advanced api to deliver xml; but when I try to parse its xml, it is not well-defined. I want to get "average rating" for a given video, but simple xml load disregard this section:
$xml = simplexml_load_file('http://gdata.youtube.com/feeds/mobile/videos/wZ252E282go');
print_r($xml);

How can I put the value of "average rating" into an string to echo?

Before you say about trying to use curl and fsockopen...I have tried those already but my host does not allow it due to their settings on their php.ini file.

I am wondering if there is a way (other than those above) to grab the latest videos from a specific user on youtube, and be able to display them on a website, such as grabbing information about the video, as well as displaying it.

If this is at all possible, and you can help...thanks in advance.

Code: [Select]
$txt = preg_replace( "#\[yt\]http://www.youtube.com/watch?v=(.+?)\[/yt\]#is", '<embed src="http://www.youtube.com/v/\\1" type="application/x-shockwave-flash" wmode="transparent" width="512" height="313" allowfullscreen="true" />', $txt );

Okay this is my code just for inserting it into HTML, the problem is whenever I try to use:

Code: [Select]
[yt]http://www.youtube.com/watch?v=l1G7TJD6Xu0[/yt]
On my form to enter it does not work?  But if I use

Code: [Select]
$txt = preg_replace( "#\[yt\](.+?)\[/yt\]#is", '<embed src="http://www.youtube.com/v/\\1" type="application/x-shockwave-flash" wmode="transparent" width="512" height="313" allowfullscreen="true" />', $txt );
Code: [Select]
[yt]l1G7TJD6Xu0[/yt]
It works.


But I want to use the full URL of the youtube, so I don't want my users to copy/paste just the "l1G7TJD6Xu0" Code , any help? Thank you

I have this function:
    function bbcode($input){
        $input = strip_tags($input);
        $input = htmlentities($input);
        
        $search = array(

        );
        
        return nl2br(preg_replace($search,$replace,$input));
    }
There is an error on code:

and on:

How can i use str_replace in this situation ? :S

Does anyone know of a json or php method of authenticating a youtube user without using zend?

Code: [Select]
<?php
$id = NULL;
$username = 'myYouTubeAccount'; 
$url = 'http://gdata.youtube.com/feeds/api/users/%s/uploads?orderby=updated&max-results=8';
$xml = simplexml_load_file(sprintf($url, $username));

foreach ($xml->entry as $entry) :

    $kids = $entry->children('http://search.yahoo.com/mrss/');
    $attributes = $kids->group->content[0]->attributes();
    $flv = $attributes['url'];
    $attributes = $kids->group->player->attributes();
    $link = $attributes['url']; 

    $querystring = parse_url($link,PHP_URL_QUERY);
    parse_str($querystring, $id_temp);
    $id = $id_temp['v'];
?>

<a href="<?=$link?>"> <img src="http://i4.ytimg.com/vi/<?=$id?>/default.jpg"  /> </a>

<?php endforeach; ?>

Hi,
Have a project, http://ziz.im
URL Shortener.

For some reason, shortened youtube links don't work. When used, they go to the youtube page, displaying a message saying the video is not available. But it's the same link (once redirected) as the original link.

Any idea what could be causing this ?

Hi,

Would time() produce the timestamp based on your time environment or the servers?, if it produces the timestamp based on the server; how would I generate a timestamp (which I can later use within date()); so it displays to the users timezone?

Code: [Select]
if ($showigiteidimage) {
                    $igitwid_divlnk = "onclick=location.href='" . get_permalink($igitwid_result->ID) . "'; style=cursor:pointer;";
                    $igitwid_output .= '<li id="igit_wid_rpwt_li" style="height:' . $igitwid_height . 'px;    padding-bottom: 10px;" ' . $igitwid_divlnk . '>';
                    $igitwid_output .= '<div id="igit_wid_rpwt_main_image"  style="float:left;">



<a href="' . get_permalink($igitwid_result->ID) . '" target="_top"><img src="<?php $values = get_post_custom_values("tj_video_img_url"); echo $values[0]; ?>" id="igit_rpwt_thumb" ></a></div>';

the prb is image src cant read the php code , what to do ? please helpppppppppp   

Ok, so I have a code that looks like so:
Code: [Select]
<script type="text/javascript">
    var ng_config = {
        assests_dir: 'ng/assets/' // the path to the assets directory
    }
</script>
<script type="text/javascript" src="ng/ng_all.js"></script>
<script type="text/javascript" src="ng/components/calendar.js"></script>
<script type="text/javascript">
var my_cal;
ng.ready(function(){
        // creating the calendar
       var my_cal = new ng.Calendar({
            input: 'enddate',
            start_date: 'year - 1',    // the start date (default is today)
            display_date: ng.get('startdate').value,  // the display date (default is start_date)
  server_date_format: 'm/d/Y'    // changing the server date format for a specific calendar.
        });
    });
var my_cal1;
ng.ready(function(){
        // creating the calendar
        my_cal1 = new ng.Calendar({
            input: 'startdate',
            start_date: 'year - 1',    // the start date (default is today)
            display_date: new Date(),   // the display date (default is start_date)
  server_date_format: 'm/d/Y'    // changing the server date format for a specific calendar.
        });
    });
how do I detect the months that pass between the two dates that are selected using a popup calendar using php so that my register page know which month to display the event under.  Does this make sense?

Hello.

Would php be the right thing to use in regards to monitoring changes in html on certain pages, Basicly, I'd need it to be something like:

"Page last changed: 2 Days, 4 Hours, 34 Minutes and 13 Seconds ago."

What would I use for this?

Thanks
