title: TYPO3 7.6 downloads extension with category filter
body: <p>I am new in TYPO3, I am working on 7.6.2 version I have to create a download PDF extension with category filters. When click on category it will display list of downloads having download icon,title and description.</p>
  
  <p>I also used 'kk_downloader' extension,Followed all extension manual but I am getting this error on frontend page where list of all downloads will have to display - </p>
  
  <blockquote>
    <p>No data, possibly missing ID!?</p>
    
    <p>These are the SQL-Select-Parameters:"</p>
    
    <p>Tabelle = "tx_kkdownloader_images"</p>
    
    <p>where = "tx_kkdownloader_images.deleted = 0 AND
    tx_kkdownloader_images.hidden = 0 AND tx_kkdownloader_images.pid IN
    (37) AND tx_kkdownloader_images.sys_language_uid=0"</p>
    
    <p>group = "tx_kkdownloader_images.uid"</p>
    
    <p>order = "tx_kkdownloader_images.crdate ASC"</p>
  </blockquote>
  
  <p>I don't know how to edit the extension and solve this problem. I also did not find any other download extension with category filter.</p>
  
  <p>Thanks!</p>
