Is there an easy way to convert a large string of chained transformations from a URL and then convert it with cloudinary_url so I can sign_url and change quality.  Thank you very much in advance

  Hi Michael,

  Unfortunately there is no direct way of accomplishing this.
  A possible workaround:
  1. Separate the long url into 2 separate strings containing the public_id and the raw transformation respectively.
  2. Replace the quality param with a string search & replace (or just add a new quality (q_{value}) to the end of the url which will actually override any additional quality param already present in the url), and then sign it.

  Thanks, I have split apart the URL but I am now looping through the parameters i the URL and creating an object in php to use cloudinary_url to sign the url for security. Is there an easy way to sign the url? I am trying something like this:

   

  $options = [
  'quality' => "jpegmini",
  'sign_url' => true,
  "secure"=>true,
  'transformation' => $transformations
  ];
  $cloudinary_url = cloudinary_url( $upload_url, $options );

  URL signing is done based on the API_SECRET which shouldn't be placed on the client-side, therefore naturally our JS doesn't support this step. You can use the PHP DK to automatically generate signed-URLs or imitate the signature process as it's done here: https://github.com/cloudinary/cloudinary_php/blob/master/src/Cloudinary.php#L514

  Makes sense?
