maxFileSize and acceptFileTypes in blueimp file upload plugin do not work. Why?

Question

I\'m using Blueimp jQuery file upload plugin for upload files.

I had no problem in uploading but the option maxFileSize and acceptFileTypes

Answer 1

Just an example of event handler for Add event. Assumes that singleFileUploads option is enabled (which is the default). Read more jQuery File Upload documentation how to bound with add/fileuploadadd event. Inside loop you can use both vars this or file. An example of getting size property: this['size'] or file.size.

    /**
     * Handles Add event
     */
    base.eventAdd = function(e, data) {

        var errs = [];
        var acceptFileTypes = /(\.|\/)(gif|jpe?g|png)$/i;
        var maxFileSize = 5000000;

        // Validate file
        $.each(data.files, function(index, file) {
            if (file.type.length && !acceptFileTypes.test(file.type)) {
                errs.push('Selected file "' + file.name + '" is not alloawed. Invalid file type.');
            }
            if (this['size'] > maxFileSize) {
                errs.push('Selected file "' + file.name + '" is too big, ' + parseInt(file.size / 1024 / 1024) + 'M.. File should be smaller than ' + parseInt(maxFileSize / 1024 / 1024) + 'M.');
            }
        });

        // Output errors or submit data
        if (errs.length > 0) {
            alert('An error occured. ' + errs.join(" "));
        } else {
            data.submit();
        }
    };
