Download all attachments of an article as zip

We often have more than a few attachments in an article. Is ist possible to add a zip download function, so you can download all attachments with one click?


Wrote a workaround in JS. Quick and dirty, but works for me.

at with position is the <script …> to add?

<!> – svgstore fallback -->

<%= javascript_tag nonce: true do -%>
detect if browser is
- Chrome 14-20
- Android Browser 4.1+
- iOS 6-7
- Safari 6
- Edge 12
- IE 9-11
window.svgPolyfill = /\bEdge/12\b|\bTrident/[567]\b|\bVersion/7.0 Safari\b/.test(navigator.userAgent) || (navigator.userAgent.match(/AppleWebKit/(\d+)/) || [])[1] < 537;

(function (doc) {

var scripts = doc.getElementsByTagName('script')
var script = scripts[scripts.length - 1]
var xhr = new XMLHttpRequest()
xhr.onload = function () {
  var div = doc.createElement('div')
  div.innerHTML = this.responseText = 'position: absolute; clip: rect(0, 0, 0, 0); z-index: -1;'
  script.parentNode.insertBefore(div, script)
}'get', 'assets/images/icons.svg', true)

<% end -%>


Since the last security patch (3.3.x) there are some changes in the way to include own js-scripts.
Now you have to replace the line:
<%= javascript_tag nonce: true do -%>
<%= javascript_include_tag “/timed_trigger.js”, “/jszip.js”, “/FileSaver.min.js”, nonce: true do %>

But that’s only half the way.
The script works with function calls inline. These are forbidden with the new policy. Heres a reprogramming with event listener necessary. Can’t findt time to do that at the moment.
Sorry for the news.

Is there any chance to apply this to zammad? Such built-in feature is sorely lacking.
