Product Edit.php

removedfile: function(file) {
             
     existingFiles_gallery.forEach(function(mockFile, index) {
          });
       var fileName = mockFile.name;
     $.ajax({
       type: 'POST',
       url: '/dropzone_upload.php',
       data: {name: fileName,request: 'delete'},
       sucess: function(data){
          console.log('success: ' + data);
       }
     });

     var _ref;
      return (_ref = file.previewElement) != null ? _ref.parentNode.removeChild(file.previewElement) : void 0;
   }

$fileName = $targetPath.$_POST['name'];  
unlink($fileName);
