maxFileSize and acceptFileTypes in blueimp file up

Question

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

I had no problem in uploading but the option maxFileSize and acceptFileTypes do not work.

This is my code:

$(document).ready(function () {
    'use strict';

    $('#fileupload').fileupload({
        dataType: 'json',
        autoUpload: false,
        acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i,
        maxFileSize: 5000000,
        done: function (e, data) {
            $.each(data.result.files, function (index, file) {
                $('<p style="color: green;">' + file.name + '<i class="elusive-ok" style="padding-left:10px;"/> - Type: ' + file.type + ' - Size: ' + file.size + ' byte</p>')
                    .appendTo('#div_files');
            });
        },
        fail: function (e, data) {
            $.each(data.messages, function (index, error) {
                $('<p style="color: red;">Upload file error: ' + error + '<i class="elusive-remove" style="padding-left:10px;"/></p>')
                    .appendTo('#div_files');
            });
        },
        progressall: function (e, data) {
            var progress = parseInt(data.loaded / data.total * 100, 10);

            $('#progress .bar').css('width', progress + '%');
        }
    });
});

Answer 1

if you have multiple file, you use a loop to verify each of the file format, something like this

add: function(e, data) {
        data.url = 'xx/';
        var uploadErrors = [];
         var acceptFileTypes = /^image\/(gif|jpe?g|png)$/i;
        console.log(data.originalFiles);
        for (var i = 0; i < data.originalFiles.length; i++) {
            if(data.originalFiles[i]['type'].length && !acceptFileTypes.test(data.originalFiles[i]['type'])) {
                    uploadErrors.push('Not an accepted file type');
                    data.originalFiles
                }
                if(data.originalFiles[i]['size'].length && data.originalFiles[i]['size'] > 5000000) {
                    uploadErrors.push('Filesize is too big');
                }
                if(uploadErrors.length > 0) {

                      alert(uploadErrors.join("\n"));
                }
        }
        data.submit();
      },

You could also use an extra function like:

    function checkFileType(filename, typeRegEx) {
        if (filename.length < 4 || typeRegEx.length < 1) return false;
        var filenameParts = filename.split('.');
        if (filenameParts.length < 2) return false;
        var fileExtension = filenameParts[filenameParts.length - 1];
        return typeRegEx.test('.' + fileExtension);
    }

You should include jquery.fileupload-process.js and jquery.fileupload-validate.js to make it work.

Answer 4

This worked for me in chrome, jquery.fileupload.js version is 5.42.3

     add: function(e, data) {
        var uploadErrors = [];
        var ext = data.originalFiles[0].name.split('.').pop().toLowerCase();
        if($.inArray(ext, ['odt','docx']) == -1) {
            uploadErrors.push('Not an accepted file type');
        }
        if(data.originalFiles[0].size > (2*1024*1024)) {//2 MB
            uploadErrors.push('Filesize is too big');
        }
        if(uploadErrors.length > 0) {
            alert(uploadErrors.join("\n"));
        } else {
            data.submit();
        }
    },

Answer 5

.fileupload({
    add: function (e, data) { 
        var attachmentValue = 3 * 1000 * 1024;
        var totalNoOfFiles = data.originalFiles.length;
        for (i = 0; i < data.originalFiles.length; i++) {
            if (data.originalFiles[i]['size'] > attachmentValue) {
                $attachmentsList.find('.uploading').remove();
                $attachmentMessage.append("<li>" + 'Uploaded bytes exceeded the file size' + "</li>");
                $attachmentMessage.show().fadeOut(10000, function () {
                    $attachmentMessage.html('');
                });
                data.originalFiles.splice(i, 1);
            }
        }
        if (data.files[0]) {
            $attachmentsList
           .prepend('<li class="uploading" class="clearfix loading-content">' + data.files[0].name + '</li>');
        }
        data.submit();                    
    }

This works for me in firefox

$('#fileupload').fileupload({

    dataType: 'json',
    //acceptFileTypes: /(\.|\/)(xml|pdf)$/i,
    //maxFileSize: 15000000,

    add: function (e, data) {
        var uploadErrors = [];

        var acceptFileTypes = /\/(pdf|xml)$/i;
        if(data.originalFiles[0]['type'].length && !acceptFileTypes.test(data.originalFiles[0]['type'])) {
            uploadErrors.push('File type not accepted');
        }

        console.log(data.originalFiles[0]['size']) ;
        if (data.originalFiles[0]['size'] > 5000000) {
            uploadErrors.push('Filesize too big');
        }
        if(uploadErrors.length > 0) {
            alert(uploadErrors.join("\n"));
        } else {
            data.context = $('<p/>').text('Uploading...').appendTo(document.body);
            data.submit();
        }

    },
    done: function (e, data) {
        data.context.text('Success!.');
    }
});
