Question

I am using Uploadify to upload files. Problem is, I need to inform users of any error during processing of those files.

Uploadify has onError, onComplete, and onAllComplete event handler but I do not know how to trigger these events so that users are informed of what is going on.

Do I need to send JSON string? There is a clue here and here and here but I couldn’t make it to work. Perhaps the posting in the forum is outdated.

Anyone got any example that works for Uploadify 2.1?

Answer 1

This was killing me but I found a way. In the uploadify.php file I created all my validation. The difference here is that I set HTTP 4xx codes for each type of error.

if (! in_array($fileParts['extension'], $typesArray)) {
    header("HTTP/1.1 405"); //any 4XX error will work
    exit();
}

This throws the “405” error back to uploadify.js.

In the file I set $(“#fileInput”).uploadify() I added the “onError” function.

        'onError' : function(event, ID, fileObj, errorObj) {
        var r = "<br />ERROR: ";
        switch(errorObj.info) {
        case 405:
            r += "Invalid file type.";
            break;
        case 406:
            r += "Some other error.";
            break;
        }

        setTimeout('$("#fileInput'+ ID + 'span.percentage").html("'+r+'");',111);
    }

This forces the uploadify default function to exist while kind of extending it.

Hope this help!
