Your own cakephp file-browser for ckeditor: part 3 - youtube videos

Here we are. The basics are still the same of the first part – making you own file explorer popup and using CKEditor.insertHtml to inject the desired generated code into ckeditor.

Of course, the same may be applied to webservices; including data form external sources is not harder than inserting your uploaded files.

At the times, I found this class – it was the best usable php youtube api wrapper, if not the only. Probably there is something new on github – but php5Tube does the job, and does it well. You may use your own choice, of course.

Here is my fork – a sligthly modified version with some features I needed

  ChangeLog
  0.4
    - Suppressed warning messages from bad feed returns and checks for empty results.  If there was a problem
         the user will recieve empty arrays out of the methods
    -Added private method parse_multi_video() to reduced the size of php5tube by reducing reused code
    -Author array entry in multi-video search is now a string and no longer a simple_xml_object
 
  0.3
  - Added ability to get a list of the most viewed videos on youtube [getMostViewed()]
 
  0.2
  - Added ability to get a video's information, given the video's youtube id [getVideoInfo()]
  - Added ability to get a video's comments, given the video's youtube id [getVideoComments()]
 
  0.1
  - Added ability to get a user's information, given the user's account name [getUserInfo()]
  - Added ability to get a user's videos, give the user's account name [getUserVideos()]

Basically, I added the search videos by keywords and category functions. (not only by user, as it was originally)
And added some tweaks to adapt it to my needs.

Code block

///*
	function getVideosByKeywords($keywords, $start_index = 1 ,$max_results = 25, $order = 'ViewCount', $category = null)
	{
 
		$feedURL = 'http://gdata.youtube.com/feeds/api/videos?q=' . $keywords . '&start-index=' . $start_index . '&max-results=' . $max_results; //.'&v=2';
 
		//add category variable to feed url, if it exists
		if ($category != null) {
			$feedURL = $feedURL . '&category=' . $category;
		}
 
		$videos = array();
		//read the feed and place it in an simple_xml object
		$xml = @ simplexml_load_file($feedURL);
		//debug($xml);
		if (!empty ($xml)) {
 
			//get the next start index.
			if (isset ($xml->link[5])) {
			    if($xml->link[5]->attributes()->rel == 'next') $this->next_index = $start_index + $max_results;
			}
			if (isset ($xml->link[4])) {
			    if($xml->link[4]->attributes()->rel == 'next') $this->next_index = $start_index + $max_results;
			    if($xml->link[4]->attributes()->rel == 'previous') $this->previous_index = $start_index - $max_results;
				//$this->next_index = (int) preg_replace('/&max-results=' . $max_results . '/', '', preg_replace('/http:\/\/gdata.youtube.com\/feeds\/api\/videos\?q=' . $keywords . '&start-index=/', '', (string) $xml->link[4]->attributes()->href));
														//http://gdata.youtube.com/feeds/api/videos?q=volontariato+ferrara&start-index=11&max-results=10
			} //if empty, then set $this->nex_index to -1 to let the user know they have reached the end of the list
			else {
				$this->next_index = -1;
			}
			//debug($this->next_index);debug($this->previous_index);
			$videos = $this->parse_multi_video($xml);
		}
 
		return $videos;
	}

Having this class in the vendors folder is half the work.

Let’s see the action and the popup view.

in our asset_controller.php

Code block

function admin_youtubebrowser($opener_instance, $start_index = 1,$max_results = 10, $order = 'Relevance', $category = null) {
 
	$category = null;
 
	//gets named parameters like posted variables - useful for filtered pagination
	$this->_clean_params();
 
	if(isset($this->data['Asset'])) {
	    if (isset($this->data['Asset']['keyword']) && $this->data['Asset']['keyword'] != '')    $keyword	    = $this->data['Asset']['keyword']; else $keyword = 'volontariato';
	    if (isset($this->data['Asset']['category']) && $this->data['Asset']['category'] != '')  $category	    = $this->data['Asset']['category'];
	    if (isset($this->data['Asset']['author']) && $this->data['Asset']['author'] != '')	    $youtube_user   = $this->data['Asset']['author'];
	    if (isset($this->data['Asset']['page']) && $this->data['Asset']['page'] != '')	    $page	    = $this->data['Asset']['page'];
	} else {
	    $keyword = 'volontariato ferrara';
	}
 
	//set the ckeditor instance id
	$this->set('opener_instance', $opener_instance);
 
	//create php5tube object and get videos
	if(App::import("Vendor", "Php5tube", array('file' => '../vendors/Php5tube.php'))) { //, array('file' => '../vendors/Php5tube.php')
	    $php5tube = new Php5tube('Video','User','Comment');
 
	    //here we are
	    if($keyword)
		$videos = $php5tube->getVideosByKeywords($keyword, $start_index, $max_results, $order, $category);
	    else if ($user)
		$videos = $php5tube->getUserVideos($youtube_user, $category, $start_index, $max_results);
 
	    $this->set('videos', $videos);
 
	    //paginate returned videos- create urls for next and previous N videos request to youtube
	    if($php5tube->next_index != -1) {
		$next_index = $php5tube->next_index;
		$this->set('next_index', $next_index);
		$url = array('controller' => 'assets', 'action' => 'youtubebrowser',
			     $opener_instance,
			     $next_index,
			     $max_results
			);
		if (isset($keyword)) $url['keyword'] = $keyword;
		if (isset($category)) $url['category'] = $category;
		if (isset($author)) $url['author'] = $author;
 
		$this->set('next_url', $url);
	    }
 
	    if($php5tube->previous_index != -1) {
		$previous_index = $php5tube->previous_index;
		$this->set('previous_index', $previous_index);
		$url = array('controller' => 'assets', 'action' => 'youtubebrowser',
			     $opener_instance,
			     $previous_index,
			     $max_results
			);
		if	(isset($keyword)) $url['keyword'] = $keyword;
		if	(isset($category)) $url['category'] = $category;
		if	(isset($author)) $url['author'] = $author;
 
		$this->set('previous_url', $url);
	    }
	}
	else {
	    $this->Session->setFlash(__('Problem: cannot import Php5tube Vendor class',true));
	}
	$this->render('admin_youtubebrowser', 'basic');
 
    }

The actions gets the filters (keywords, category or author) from the form or url parameters (preserving filters in pagination); calls the appropriate method from the php5Tube class -retieving videos data from youtube-, and then sets the variables for the view (including urls for paginated requests to youtube)

Here is the _clean_params method:

Code block

function _clean_params() {
    	if(is_array($this->params['named'])) {
 
	    foreach ($this->params['named'] as $key => $value) {
 
		if(strpos($key, 'Asset.') === 0)  {
		    $short_key = str_replace('Asset.', '', $key);
		    $this->params['named']['Asset'][$short_key] = $value;
		    //unset($this->params['named'][$key] );
		} else {
		    $this->params['named']['Asset'][$key] = $value;
		}
		//debug($this->params['named']);debug($this->params['named']);
	    };
 
	    if(isset($this->params['named']['Asset'])) {
		if(isset($this->data['Asset']))
		    $this->data['Asset'] = array_merge($this->data['Asset'],$this->params['named']['Asset']);
		else
		    $this->data['Asset'] = $this->params['named']['Asset'];
	    }
 
	}
 
    }

Then the view: the popup. like the image one in the previous article, prepares the code to be injected back to ckeditor.

The view, admin_youtubebrowser.ctp

Code block

Like we did for images, there is a choiche for different sizes and align for the video to be inserted.

With a few lines of code we have a functional browser (and search by keyword, category or author) of yuotube videos, with thumbnails and the chance to preview the actual video, integrated in our application.

It’s easy with cakephp.

Next (last) time, a flickr browser: search, browse and embed images or photoset slideshows form flickr.
