The most recommended or ideal way for this is not sending the code like you're doing currently (client sided) but server sided with a function
#[SOLVED] Button Clickable every 24h
turbid ether
That way you're 100% sure 24h has passed from last time the button was clicked and the user can't "hack" the app to override the timer
frozen fiber
how can I get started with function ?
turbid ether
For that you will need an appwrite function with database that checks latest time the user clicked the button and if it was after 24h from latest time, you send the command

thx, if I ever need help I can write here ?
turbid ether
Yes, of course!
frozen fiber
aight

thank you man
last thing
before starting that topics what do you suggest me to learn or have a basic knowledge
like http request like i see in the docs or more

Do you have knowledge on Appwrite Auth?
You're doing this in flutter, right?
If so, you will need to learn (in the following order):
- Auth for flutter
- Databases API (in your case for flutter SDK)
- Functions
It looks difficult, at least it appeared to me when I started, mainly functions, but believe me that everything is a lot easier than what looks to be
You don't need to learn another programming language or similar if going with flutter since Appwrite functions can be easily written with Dart (the programming language Flutter uses) unlike other Appwrite competitors

hii
it's me again
i started taking a look at function but i was wondering if this would work for separate user, supposing the user send an http post/get request at the function this would work for separate user or the same function would work for all the user
because i want this to be subjective for each user

no need to tag the entire company 🙂 We always see your messages here without being tagged 🤗 btw that is amazing you are starting developing early on, you will be very successful because of this 
@turbid ether thank you for helping this person 🙂

In your case - as D5 suggested - you should use server-side code in an Appwrite Function to correctly send alerts to the users.
If you are storing the last time at which the user pressed the button in a document inside a database, what you can do is this:
Whenever the user starts the app, run a databases.getDocument call from your app and check if the time stored in the document is more than 24 hours ago. Something like this:
Future result = await databases.getDocument(
databaseId: '[DATABASE_ID]',
collectionId: '[COLLECTION_ID]',
documentId: '[DOCUMENT_ID]',
);
final lastUserTime = result.timeByUser; // timeByUser is the name of the attribute in the database's collection that holds the actual time
bool isMoreThan24HoursAgo(String isoTime) {
DateTime dateTimeA = DateTime.parse(isoTime).toUtc();
DateTime currentDateTime = DateTime.now().toUtc();
Duration difference = currentDateTime.difference(dateTimeA);
return difference.inHours > 24;
}
This will return true if more than 24 hours have passed, and false if less than 24 hours have passed.
If the value returned by the isMoreThan24HoursAgo function is true, you can show the button.

is this gonna work if the client move the time on his phone ?
turbid ether
is this gonna work if the client move the time on his phone ?
Phone time will not affect
Because this is done server sided
Phone = client side
Appwrite = server side
frozen fiber
but this line of code takes the date from the client side?
DateTime currentDateTime = DateTime.now().toUtc();

When you click the button, you create a new database record or update existing. Database API or function will record existing creation/modification time from server side

hi, it's me again, do you guys think i can implement this logic to make a different "Cooldown" for every user?
in the code below if the parameter UserID (wich i've taken and stored in a variable) is not found on the collection of the database that contains the UserID and the timeByUser, he'll create a new one, otherwhise i will update the exsisting one.
i'm also not sure this is the best practice to do this, but i think can be work good right?
(edit: iv've inplemented this today and when the user clicks the button it checks if there is the UserID already in the document otherwhise he will create a new document with that specific user id, also the GetUserID() is a function to get the id of the user in the current session)
void getuser() async {
try {
final userId = await GetUserID();
Future<bool> userExist() async {
try {
final response = await databases.listDocuments(
databaseId: '651b24f731b2855ab92d',
collectionId: '651b253f714e3fb0c8a7',
queries: [Query.equal('UserID', userId)],
);
// Verifica se ci sono documenti nel risultato
return response.documents.isNotEmpty;
} catch (e) {
print(e.toString());
return false;
}
}
if (await userExist()) {
print('UserID already exists in the collection');
} else {
await databases.createDocument(
databaseId: '651b24f731b2855ab92d',
collectionId: '651b253f714e3fb0c8a7',
documentId: ID.unique(),
data: {
'UserID': userId,
'timeByUser': 'not_setted_yet',
},
);
print("Document created");
}
} catch (e) {
print(e.toString());
}
}
This code seems to the job of checking if user exists, and then either creating/updating document correctly
Is there anything else you want to do?
