youtube search api request function

This function requests a search from the youtube search api, and searches the text in the snippet for the seearch string. You can get your own API key for this from the google developers console. They allow you to have 10000 credits on the API (per day in the free tier), and one search equals 100 credits at the time of writing this, so you can get 100 searches in the free tier. 

I think its a good idea to restrict this API key to just access the youtube as well.

You can pass in the search_query into your function here, to get it to search for the string. 

Replace the $apikey with your own! :)

In this example it just adds all the values to $out and then returns out, but you can see what else is available in the search results by var_dump($data) if you want to see what is being returned or you can refer to the api docs. 

In my example you can see that i also add an iframe code, and also the video view url, which i didnt see in the feed as they only seem to provide the id, but maybe i just missed it. 

Also i added the max res thumbnail as $thumb_max as they seemed to miss this as well, even though some of the videos dont provide the max res one. 


public function youtube_search_api (
    $loop_max = 10
  ) {

      global $db;
      global $functions;
      $out = "";
      $for_counter = 0;
      $main_loop_tag = ".page_content_ctn";
      $db_table_name = $this->db->escapeString($this->db_table_name);
      $loop_max = $this->db->escapeString($loop_max);

      $search_query = $_GET['search_query'];
      $search_query_enc = urlencode($search_query);
      $search_query_decode = urldecode($search_query);

      /* $import_url_search = $this->import_url; */
      /* $import_url_search = str_replace ( "[@search_query]" , $search_query_enc , $import_url_search); // replace... [@search_term] */

      if($search_query >= "") {} else { return false; } // if no game url just return.

      save the html file for testing to see if the grabbed file is the same as the one in browser.
      echo $import_url_search;
      file_put_contents ( "./youtube_test.html" , file_get_contents($import_url_search) );
