Advanced Script to Check Document Size before upload

[RentProperty]

Hi guys,

Just thought we'd share this Scriptlet we got working for checking document size before it is uploaded to AwareIM. I.e. the size is checked when the document is selected.

You can put it in the Advance Initialization Script of the Form and change the size and message. Works like a charm for us:

Code: Select all

for (var i = 0; i < widgets.length; ++i) {
    if (widgets[i].type == "upload") {
        widgets[i].config.select = function onSelect(e) {
            $.each(e.files, function (index, value) {
                if (value.size > 5000000) {
                    e.preventDefault();
                    alert("Document too large (>5mb) - please resize the document and try again.");
                }
            });
        };
    }
}

Thanks for sharing. I believe I can say for a fact that my server has been brought down several times by one or more users uploading a large document. Everyone should deploy this script where you have document uploads. Since deploying a similar solution, I have had no problems.

if (value.size > 5000000)

Is it possible to have value.size > look at an AwareIM SystemSettings attribute rather than a hard coded value?

Hi,

would this work if you have the attribute set as 'use multi-file upload for document attribute'??

Thanks

Hi Tom & Chris, Not sure. Haven't played around with different implementations yet. Things are bit crazy at the moment.

But the default implementation definitely works for a single document.
