replace youtube link with embed video

[AviNahum]

i trying to replace a simple youtube link with the embed video, for example:

this:

http://www.youtube.com/watch?v=iabgQJLqTD4&playnext_from=TL&videos=0pS3nK3dxJs&feature=sub

 

will be replaced with:

<object width="640" height="385"><param name="movie" value="http://www.youtube.com/v/iabgQJLqTD4&hl=en_US&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/iabgQJLqTD4&hl=en_US&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="385"></embed></object>

 

so here is my code:

$row['post'] = preg_replace(
			"#(.+?)http://www.youtube.com/watch?v=[a-zA-Z0-9._-](.+?)#is",
			'<object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/\\1&hl=en_US&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/\\1&hl=en_US&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>',
			$row['post']
		);

 

it does not work...

i dont really good at regular expressions so i dont really know what i did there... i just played with that...

the most important thing is that the youtube link can be i a middle of a paragraph  like this:

some text here

some more text

http://www.youtube.com/watch?v=iabgQJLqTD4&playnext_from=TL&videos=0pS3nK3dxJs&feature=sub

some text here

some more text

 

any ideas?

Thanks in advance!

$yturl = str_replace('watch?v=', 'v/', $row['post']);

$str = '<object width="640" height="385"><param name="movie" value="'.$yturl.'&hl=en_US&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="'.$yturl.'&hl=en_US&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="385"></embed></object>';

echo $str;

 

I already made one of these kind of script for a database of youtube videos that are called back using $_GET from the page url and calling that from the database ID number.

 

How this works is it replaces watch?v= with v/ from $row['post'] and puts it into a string called $yturl then replaces the variable $yturl from the string $str with the fixed url into that embed code and calls it back through the echo.

Try this

$yObj = "\n
     \n
     \n
     \n
     \n
\n";
$yLink = preg_replace("#http://www.youtube.com/watch?v=([a-zA-Z0-9]+)&#", $yObj);

first, thanks!

but you missed the part where i sad that the link can be in a middle of a paragraph...

i need to catch the youtube link in the paragraph and replace only the link with the embed code...

$yObj = "<object width='480' height='385'>\n
     <param name='movie' value='http://www.youtube.com/v/\\1&hl=en_US&fs=1'></param>\n
     <param name='allowFullScreen' value='true'></param>\n
     <param name=allowscriptaccess' value='always'></param>\n
     <embed src='http://www.youtube.com/v/\\1&hl=en_US&fs=1' type='application/x-shockwave-flash' allowscriptaccess='always' allowfullscreen='true' width='480' height='385'></embed>\n
</object>\n";
$yLink = preg_replace("#http://www.youtube.com/watch?v=([a-zA-Z0-9]+)is", $yObj,$subject);

Crayon your pattern isn't fully correct. Youtube can have _ and - in the video ID's. I'd use this as your pattern:

'/v=([^&]+)/'

Well I'm not psychic, the OP didn't mention that.  Also I just modified what Zanus already did.  Thanks for pointing that out though.  It is a common occurrence in this forum for people to not fully explain what a string/value can be/contain.  As they say, GIGO.
