I'm not sure this addon is working with current Alfresco release:

GitHub - softwareloop/uploader-plus: An Alfresco uploader that prompts for metadata

But it's providing the feature you are looking for.

Thank you. Yes, it's almost what i want. I can't use the addon directly, so i try to develop a similar one.

I have created a type in my model associated to the aspect :

<types>
   <type name="ns:typetest">
      <parent>cm:content</parent>
      <mandatory-aspects>
         <aspect>ns:myAspectName</aspect>
      </mandatory-aspects>
   </type>
</types>

And I defined my form in the extension :

<config evaluator="model-type" condition="ns:typetest">
   <forms>
      <form>
      ...

I can now display the form in a "metadata" div on the dnd-upload page with the following code :

Alfresco.DNDUpload.prototype.onFileSelection = function DNDUpload_onFileSelection(evt){
   Dom.removeClass("metadata", "hidden");
   var url = YAHOO.lang.substitute(
      "{serviceContext}components/form"
      + "?mode={mode}&itemKind={itemKind}&itemId={itemId}&htmlid={htmlid}"
      + "&destination={destination}&siteId={siteId}&containerId={containerId}&uploadDirectory={uploadDirectory}",
      {
         serviceContext : Alfresco.constants.URL_SERVICECONTEXT,
         mode: "create",
         itemKind : "type",
         itemId : "alpro:typetest",
         htmlid : "something",
         destination: encodeURIComponent(this.showConfig.destination || ""), // empty field ?
         siteId: encodeURIComponent(this.showConfig.siteId || ""),
         containerId: encodeURIComponent(this.showConfig.containerId || ""),
         uploadDirectory: encodeURIComponent(this.showConfig.uploadDirectory || ""),
      });
   Alfresco.util.Ajax.request({
      url: url,
      successCallback: {
         fn: function(response) {
            YUIDom.get("metadata").innerHTML = response.serverResponse.responseText;
         },
         scope: this
      }
   });
}

My next step is to send the form to save the file and the metadata but i don't know how to do it.

Currently, I can't send the form ("javax.servlet.ServletException: Possible CSRF attack noted when comparing token in session and request parameter. Request: POST /share/proxy/alfresco/api/type/ns%3Atypetest/formprocessor").

Can you explain me the step for the save ?
