UploadFile callback is not being triggered in CKEditor

I added filebrowserImageUploadUrl option here:

CKEDITOR.replace(         


        

Answer 1

As it was guessed by @Wiktor the issue was in setting proper headers. I was almost there, setting wrong headers.

Right headers are obviously: "text/html" (not "plain/text", it recognizes it just as a text in this case)

    $uploadResponse = new Response();
    $uploadResponse->headers->set('Content-type', 'text/html');

    $content = "<script type=\"text/javascript\">\n";
    $content .= "window.parent.CKEDITOR.tools.callFunction(" . $funcNum . ", '/uploads/news_image/" . $response['uploadedName'] . "', '');\n";
    $content .= "</script>";

    $uploadResponse->setContent($content);
