mediaelement.js – Play random video?

1 comment

1. This should be possible.

   What you might want to do is use AJAX to generate the div containing your video player. If you do this, you can delete/recreate the player very easily.

   After that what you’d need is a shortcode definition which feeds a directory string value and a boolean value into whichever function you attach to the shortcode handler.

   For Instance

   $defaultDirectory=site_url()+”/videos/”;

   add_shortcode( 'video', 'videoDiv' );
   
   function videoDiv( $shortcodeAttributeList )
   {
     extract( shortcode_atts( array(
                'src'    => $defaultDirectory,
                'random' => true,              /*set default values, use lowercase*/
            ), $shortcodeAttributeList ) );
   
     if($random)
     {
         $numFiles=fileCounter($src);
         $choice=rand(1, $numFiles);
     }
   
     $output='<div id="videoPlayer" class="player">';
     // Continue by making a string which spans from <div> to </div>
   
     return $output; //a div
   }
   

   Also from http://php.net/manual/en/function.readdir.php

   <?php
   /**
   * get the number of files within a given dir
   */
   function fileCounter($dir){
       $counter = 0;
       if ($handle = opendir($dir)) {
         //echo "Directory handle: $handlen";
         //echo "Files:n";
         /* This is the correct way to loop over the directory. */
         while (false !== ($file = readdir($handle))) {
             //echo "<BR>".$counter." - $file";
             $counter++;
         }
         closedir($handle);
       }
       $counter -= 1; // in order to exclude '.' and '..', as well as start the counter on 1
       return $counter;
   }
   /**
   * get the filename in a giver dir, starting the first file with the index 1
   */
   function fileNameByIndex($dir, $fileIndex){
       $counter = 0;
       if ($handle = opendir($dir)) {
         while (false !== ($file = readdir($handle))) {
             $counter++;
             if($counter - 2 == $fileIndex)
                 return $file;
         }
         closedir($handle);
       }
       return "";
   }
   }
