Multiple upload files new function
Does this script still work? I found it in an old thread?
I'm assuming the data source would be something like:
LoginDB__files_upload_service // a service which uploads files to the files collection
and the file list would be at least 1 file such as:
image_base64_1 // A picture from the camera
or an array of file names taken with the camera?
I have saved 6 pictures from my camera into local storage and would like to upload all 6 to the files database. They are stored in Local Storage:
image_base64_1
image_base64_2
image_base64_3
image_base64_4
image_base64_5
image_base64_6
// Here's the function I'm talking about
function uploadMultipleFilesHelperNew(datasource, fileList) {
var isCorrectService = false;
if (datasource) {
if (datasource.service && datasource.service.requestOptions) {
var options = datasource.service.requestOptions;
isCorrectService = options.type === 'post' && options.contentType === false && /^.*\/files$/i.test(options.url);
}
}
if (isCorrectService) {
if (fileList) {
var data = new FormData();
for (var i = 0; i < fileList.length; i++) {
appendItem(data, fileList);
}
try {
datasource.execute({
'allowDataModification': false,
'processData': false,
'body': {data: data},
'cache': false
});
} catch (exception) {
console.log(exception.name + ' ' + exception.message);
hideSpinner();
}
}
} else {
console.warn('This data source not be supported in the method of upload multiple files');
}
function appendItem(formData, item) {
if (item) {
if (item.type === 'file') {
item = item.files;
}
if (item instanceof FileList) {
for (var i = 0; i < item.length; i++) {
appendItem(formData, item);
}
return;
}
var name;
if (item.name) {
name = item.name;
}
formData.append(name, item);
}
}
}
