TASK: PhoneGap application uploading photos to filepicker.

  • I managed to use Filepicker within the app.
  • I managed to use other uploader with native input: http://blueimp.github.io/jQuery-File-Upload/
  • What didn't manage though is to upload to Filepicker using native (for iOS6) input type="file"

                    console.log(loc);
                    if(loc.indexOf("fpurl") > -1) {
                        cb.close();
                    }
                    var n = loc.split("fpurl=");
                    fpurl = n[1];
                    alert(fpurl);
                }
            };
            cb.showWebPage("https://www.filepicker.io/dialog/open/?m=image/*&key=______YOUR_KEY_HERE______&referrer=&modal=false&redirect_url=https://www.filepicker.io/dialog/phonegap_done/");
        }
    }

    $(function(){
     $("input#file").on("change", function() {
        ("textarea#base64").val($(this).val());

        /* _____WHAT TO PUT HERE_____ */

     });
    });

    </script>

    <body>
    <h3>function calling Filepicker API</h3>
    <a href="#" onClick="useFilepicker(); return false">Use Filepicker</a> 
    <!-- this works, but user experience suffers - I don't want to open extra window, I would like to have take photo / choose existing -->


    <h3>input type=&quot;filepicker&quot;</h3>
    <input type="filepicker"/>
    <!-- Doesn't work, created issue here: https://github.com/Filepicker/filepicker-phonegap/issues/1 -->

    <h3>input type=&quot;file&quot;</h3>
    <form action="_____WHAT TO PUT HERE_____">
        <input id="file" type="file"/>
    </form>
    <textarea id="base64">Here c:/fakepath/image.jpg path with be</textarea>

    </body>
</html>

Note: this code uses ChildBrowser plugin, you may want to follow these instructions: https://github.com/alunny/ChildBrowser/issues/28#issuecomment-15941458

Extra points: how to use library like - https://gokercebeci.com/dev/canvasresize (plugin for client side image resizing) to reduce filesize before transmiting data using fleaky 3G connection?

Thank you in advance for any suggestions ans support.

You can use the filepicker.store function to store native input types, for instance:

var input = document.getElementById("my-file-input");
filepicker.store(input, {location:'S3'}, function(fpfile){
    console.log(JSON.stringify(fpfile));
});

Here is a minimal snippet that works (uploading large photos take time and there is no progress bar so be patient)

<!DOCTYPE html>
<html>
    <head>
        <title>Filepicker PhoneGap iOS6</title>
    </head>

    <script type="text/javascript" src="cordova-2.2.0.js"></script>
    <script type="text/javascript" src="jquery.min.js"></script>
    <script type="text/javascript" src="filepicker.js"></script>
    <script type="text/javascript">

    filepicker.setKey('l5uQ3k7FQ5GoYCHyTdZV'); // No worries: used filepicker's

    $(function(){

     $("input#file").on("change", function() {

        filepicker.store(this, {location:'S3'}, function(fpfile){

            $("<a>", {
                href: fpfile.url,
                text: "See me!"
            }).appendTo("body");

        });
     });
    });
   </script>

    <body>
        <input id="file" type="file"/>
    </body>
</html>
