Help with login authentication and offline webapp

2014-03-21 Thread Bart Cockheyt
Hy,
 
I'm making an 1 file webapp (different screens in 1 html file) with user 
authentication.
I tried different type of scripts but all seem to lack to work flawless 
with the iUI screen setup.
If i use a script with separate login files it screws up the backlink in 
the topbar (displaying the login link in the first screen).
Another thing is that it uses a mysql database to store the userdata, thats 
ok, but one of the goals of the webapp is to also make it usable when 
offline (cache).
Has anyone any ideas on how to implement something like this (if possible 
with working example)?
 
What i need to do is this:
 
- Making the login screen part of the index screen (load screen login if 
not logged in, else display other content, or a script that can handle the 
#_screenid tag)
- Using a cacheble database (secure so no flat file, maybe msqli?) so it 
also works when site is cached/offline
- Letting users change there password
- If possible admin the users when logged in as admin, add users, delete 
users, change user password.
- NO user registration
 
Curently i'm using this script: http://php-login-script.com/
It works but i have the backlink isue and the stay logged in doesen't 
work (and is not going to work for offline usage), but it gives an idea of 
what i'm trying to do here.
 
Any help, pointers, tutorials, scripts are welcome.

I use PhoneGap and get my data from an external site using JSON

Hy,
 
It's not a native app but a 100% web-app.
Its going to be used by a select group of users but one goal is that thay 
can still use the app if there is no internet available.

Do you need all that user management?
How about a single fixed excrypted password in javascript?

2014-03-21 Thread Remi Grumeau
Hi Bart,

Is content dynamic or static?

If static and not sensible, you do the login/pass test only online on first 
access and use manifest to cache all files locally.
If dynamic, then well ... it's a complicated job :)

Re: Help with login authentication and offline webapp

2014-03-21 Thread Bart Cockheyt
Hi,
 
I don'r realy need all, it would be usefull but not needed.
What i do need is letting the user change its password.
That's the only right the user is granted.
Every thing eles, from creating acount to managing is is done by admin, 
directly in database or using something like a admin gui.
 
one login is not an option.
it is used by my company and if someone leaves the company we can 
block/delete his useracount.
 
The user is suposed the be online 100% of the time, but sometimes there is 
no network but i would like to still offer most of the content in those 
sitiuations.

Content is static.
 
Its also sensible, so i need a userbased login.
Only first time login is no option.
only login online but not offline(using some sort of offline check) is an 
option.

Re: Help with login authentication and offline webapp

The content itself is static.
There are a few dynamic bits but the user is warned that those do not work 
when offline.
 
Its content is sensible, i'm ok if it only checks login when online, but 
i'm not doing it just once...

Not completely.
I do need to give the user the ability to change its password.
Everything else can be done directly in database bij admin or using an

Re: Help with login authentication and offline webapp

2014-03-21 Thread Remi Grumeau
There is only one way to get a webapp offline today: cache manifest.

Cache manifest is pretty simple on the paper: once online, you access to an
url. This url as a manifest attribute in the html tag, so the browser
knows where to find it and read it.
This file is a list of urls you want the browser to keep a copy locally.
Those urls are grouped as cache, fallback  network. urls could refer
to any file (except videos afaik). But once the browser have cached those
urls locally, he will simply not ask the server again to serve this file.
except the manifest file itself got corrupt, updated or is missing. Even is
user phone/tablet has signal. That's the whole point.

This is why i'm asking if the content is sensible and if you need offline
login.

If not, then do the login online, and only put a manifest reference on the
html tag once user is logged in. So you know only logged users can has a
manifest-based local copy of the app.
This could be simple to implement, but means you store the app  its
content in its logged status  until user keeps offline, he can access
app+content forever. (if user is banned or fired, just empty his/her
manifest file and app would be removed locally - then next time it would
ask online to the server to serve the content - login screen).

If you need user to login each time + have dynamic content, then you need
to totally recreate the app to split everything between what's the app 
what's the content. So you can use the manifest file to store what is the
app files, and populate the app with datas from the online database via
Ajax calls (when online) or from the local storage (localStorage or
localDatabase are the two options). The exact same process of a native app
in fact, and the only way to do it properly. Here, you can ask online for
login/pass check, and fallback to an localStorage hash test when no signal
/ too long.

Not an easy job for sure, but a very interesting one, and totally
server-side tech agnostic (in both cases).


I'll give you 2 examples using Emy rather than iUI just because demos are
online and functional, but the exact same could be done with iUI since it's
not really related to the frontend library at all.

Emy cache manifest plugin :
http://www.emy-library.org/emy/1.0/plugins/cache-manager/cache-manager-demo.html
(see you the logo image switch from online to offline, based on what's
in fallback in its manifest file)

Emy Note app demo : http://www.emy-library.org/demos/notes/notes.html
(see how views are empty, datas stored in localStorage as a JSON string,
parsed onload to populate the app)

Hope this help.

Remi
