Zend-framework: YouTube video link validation - php

Question

is any method to validate Youtube video link with Zend-framework ?
If user inputs not valid link, for example http://www.youtube.com/watch?00zzv=nel how can I check it before inserting into site ?

Answer 1

I'm pretty sure that there is no built in validator for this, but writing custom validators is super easy:
class My_Validate_Youtube extends Zend_Validate_Abstract{
public function isValid($value){
// check url here
if (no_good($value)){
$this->_error("Explain the error here");
return false;
}
return true;
}
}
Just put whatever checks you need in that class, and run the validator on any Youtube links to be checked.
edit:
From Laykes, you might want to consider using the validator to check if the video actually exists, instead of determining if it fits a pattern. Depends on your use cases though- eg how much latency do you want to introduce by making a call to the Youtube API?

Answer 2

I don't know if it is possible, however, I would take a different approach and try and see if the link has comments on it.
Take this for example. From here:
http://framework.zend.com/manual/en/zend.gdata.youtube.html
$yt = new Zend_Gdata_YouTube();
$commentFeed = $yt->getVideoCommentFeed('abc123813abc');
foreach ($commentFeed as $commentEntry) {
echo $commentEntry->title->text . "\n";
echo $commentEntry->content->text . "\n\n\n";
}
If you use the video id in the VideoCommentFeed argument, you will be able to get the value in $commentFeed. If you then get an error, you know that the video does not exist.
I am sure if you try other methods you will probably find example what you want.
