Passing values with a "?" to a snippet

I have a call to a snippet:

[[+youtubevideo:!empty=`[[!ShowYouTubeClip? &clip=`[[+youtubevideo]]` ]]` ]]

The problem is that the youtubevideo parameter can contain odd characters like question marks, the snippet will not execute if it sees these.

Tried surrounding it in quotes - even before it was passed to the placeholder, still does not work.

How can I pass a url that looks like this: http://www.youtube.com/watch?v=x9AwgIkSReI&feature=related to a snippet

-thanks

I think that would work in Revolution, but in Evolution, you need to use some other characters or character combinations for the illegal characters in the snippet tag and then use str_replace in the snippet to convert them back.

@sean - you could look at using the urlencode output modifier to encode all those funny url characters. However if the videos are always going to come from youtube then would it be possible to simply store the video id and pass that to the snippet instead?

Eg. youtubevideo: x9AwglkSRel

Then in your snippet you can build the youtube url back up and only return something if the clip param is not empty:

<?php
$output = ''
$clip = trim($modx->getOption('clip'));
if (!empty($clip)) {
    $url = 'htt p://www.youtube.com/watch?v=' . $clip . '&feature=related';
    // get video markup chunk
    $output = $modx->getChunk('youtube-video-markup',array('url' => $url));
} 

return $output;

That way you'll also avoid output modifiers which are unfortunately not so efficient.

[[!ShowYouTubeClip? &clip=`[[+youtubevideo]]`]]

Thanks guys;

I wound up doing something like this [since there are several different formats of clip a user may enter!]

<?php
$clip = str_replace('QUERY','?',$clip);

	// short url
	if(stristr($clip,'youtu.be/')){

		$video = explode('.be/',$clip);
		$video =$video[1];
		$videoclip = 'http://youtube.com/v/'.$video.'?version=3&hl=en_US';
	
	}
	
	// pasted url	
	if(stristr($clip,'watch?v=')){
		$querystring = explode('?',$clip);
		$video = explode('&',$querystring[1]);
		$video = str_replace('v=','',$video[0]);
		$videoclip = 'http://youtube.com/v/'.$video.'?version=3&hl=en_US';  
	}
		
	// default old url version
	if(stristr($clip,'/v/')){
		$videoclip = $clip;
	}

	
	$youtubevideo = array();
	$youtubevideo['videoclip'] = $videoclip;
	
	$output = $modx->getChunk('YouTubeVideoTpl',$youtubevideo);


return $output;
