LOGIN SYSTEM USERNAME AND PASSWORD ISSUE

[VasilisMp]

My previous question got answered https://groups.google.com/forum/#!category-topic/mitappinventortest/specific-programming-issue/windows-8/chrome/phonetablet-with-the-wifi/home-network/mit-appinventor-2/iOIM-eR5gGo, but another one arose. The login system works, i mean that all the values are succesfully stored on the lists but if i have 2 usernames on the list and 2 passwords i can login with any combination of these which i do not want. How could i solve it? 

(if you want more screenshots of the app tell me)

Test for the value of name and password from the same index

Might be better to store names and passwords in one list (list of lists / table) so they are in alignment

Can you be more specific about the first? Could you, please, post a screenshot of the code? Because mine, if i do it right, does not work. It also causes an error.

[TimAI2]

Can you please share your aia project file

Here it is my friend.

I will need to do a fair amount of reworking, you have multiple screen issues and also multiple "login process" issues

Hopefully I will have time this evening (UK time)

Thanks you so much!

Hmmm, well it works, 292 blocks just to login. It is a bit long winded due to time constraints, debugging and trying to stick to your original design.

With a bit of extra work, this can be streamlined somewhat.

All done on a single screen, using 4 vertical arrangements

For development/debugging:

I added a back to Start routine when on the "App" page to start again

and a clear tinydb button

aia attached (recommended to start here, but see blocks below)

Thanks you, but for a reason google does not let me to download the .aia because it is dangerous. However, you can post the project on the app inventor gallery and then send me a link from there.

[TimAI2]

You should be able to override the dangerous part but here is gallery link

Thanks a lot!

The only thing I didn't do is set a variable for "who is actually logged in"

Going forward you can share the tinydb data with the cloud, maintain it from there and re-up it to the app if you wish
