So I have been working on my website for a while which all is php&mysql based, now working on the social networking part building in similar functions like Facebook has. I encountered a difficulty with getting information back from a link. I've checked several sources how it is possible, with title 'Facebook Like URL data Extract Using jQuery PHP and Ajax' was the most popular answer, I get the scripts but all of these scripts work with html links only. My site all with php extensions and copy&paste my site links into these demos do not return anything . I checked the code and all of them using file_get_contents(), parsing through the html file so if i pass 'filename.php' it returns nothing supposing that php has not processed yet and the function gets the content of the php script with no data of course. So my question is that how it is possible to extract data from a link with php extension (on Facebook it works) or how to get php file executed for file_get_contents() to get back the html? here is the link with code&demo iamusing: http://www.sanwebe.c...-php-and-jquery thanks in advance.

How could I from the varying URLs parse only the YouTube video ID?


http://www.youtube.com/watch?v=SwrawcORlp0&feature=player_embedded
http://www.youtube.com/watch?v=SwrawcORlp0&feature=popular

How can I from the URLs above only extract the id into a variable $url

Thanks, df

Code: [Select]
<form name="commentbox" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<table border="0">
<textarea name="comment" cols="20" rows="2"
onclick="document.commentbox.comment.value='';"
onfocus="this.style.borderColor='yellow';"
onblur="this.style.borderColor='blue';"
/>Comment...</textarea>
</td></tr>

 $commentcheck = $_POST['comment'];

 if ($commentcheck == "Comment...")
 {
 die(' <META HTTP-EQUIV=\"Refresh\" CONTENT=\"1; URL=index.php\"> ');
 }else

why does this not refresh if i comment "Comment..." it just dies and doesnt echo anything

Okay...

Since my last post about the website I was working on, I've figured out what I was asking.  But now, I've run into another problem...

Once I have a functional form on my website where a user inputs data and presses submit, how do I go about getting it to remain posted where directed?  So if the user types his first and last name and presses submit, how do I get their input to remain posted on the page, much like a guestbook?

I'm a newbie at this stuff, but it's a must for mine and my partner's website.  Thanks again!

PS... I have the code for the form all typed out and it works, it just displays the data with $echo rather than posting it permanantly.

I have this function:
    function bbcode($input){
        $input = strip_tags($input);
        $input = htmlentities($input);
        
        $search = array(
                    '/\[b\](.*?)\[\/b\]/is',
                    '/\[i\](.*?)\[\/i\]/is',
                    '/\[u\](.*?)\[\/u\]/is',
                    '/\[img\](.*?)\[\/img\]/is',
                    '/\[url=http://(.*?)\](.*?)\[\/url\]/is',
                    '/\[color=(.*?)\](.*?)\[\/color\]/is',
                    '/\[yt\](.*?)\[\/yt\]/is',
        );
        
        $replace = array(
                    '<b>$1</b>',
                    '<i>$1</i>',
                    '<u>$1</u>',
                    '<img src="$1" style="border:0">',
                    '<a href="$1">$2</a>',
                    '<font style="color:$1">$2</font>',
                    '<object width="660" height="405">
                    <param name="movie" value="'.str_replace("watch?v=", "v/", $1).'" />
                    <param name="allowFullScreen" value="true" />
                    <param name="allowscriptaccess" value="always" /><embed type="application/x-shockwave-flash" width="660" height="405" src="'.str_replace("watch?v=", "v/", $1).'" allowscriptaccess="always" allowfullscreen="true"></embed>
                    </object>',
        );
        
        return nl2br(preg_replace($search,$replace,$input));
    }
There is an error on code:
<param name="movie" value="'.str_replace("watch?v=", "v/", $1).'" />
and on:
<param name="allowscriptaccess" value="always" /><embed type="application/x-shockwave-flash" width="660" height="405" src="'.str_replace("watch?v=", "v/", $1).'" allowscriptaccess="always" allowfullscreen="true">
How can i use str_replace in this situation ? :S

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

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;
          }
           
          }
          ?>

Has anyone had any success doing this?

I'm not sure if I should try to write this myself or use some kind of framework. I found the Zend Gdata framework (http://framework.zend.com/manual/en/zend.gdata.html) and tried it out but I kept getting error: Warning: include_once() [function.include]: Failed opening '1' for inclusion (include_path='.:/usr/share/pear')

I'm assuming it needs to find PEAR which I don't have installed but no where in the Zend docs does it say that it requires PEAR so I'm a little confused. I've never used any of the Zend frameworks so I have no idea if it needs PEAR or not.

Anyone have any other methods for doing this?

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:

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 )
