My web app is working on local and not online

🤯😲😲😲😲

How is it possible?

AJAX Call not working.
Not sending data😟

CORS?

@stop what do you mean?

Cross-Origin Resource Sharing. If your content is on another domain, you get errors, because the browser blocks connections. You can see it in the console of the browser.

@stop sounds like it

Give us an error and we might be able to help properly :)

Local is using 127.0.0.1/someFile.ext

And online is using 127.0.0.1/someFile.ext

I've done this before 😂

Seriously give us some errors - open console and go digging.

@M1sf3t working from home has its drawbacks. 🤨 wait... did I just find a human?

@C0D4 one query is failing online

But the connection to the database is fine

@Afrographics

Can you run the query directly against the db - not through php?

Does the result actually have any records?

Are you actually giving mysqli_query() the db connection in the arguments?

mysqli_num_rows( $result );

Or are you using prepared statements?

So much could be going on without seeing the actual code.

@C0D4 thanks dude

But i think i figured out what is going on

Actually i'm testing my chat application by using a free hosting service.

And i commit to refresh the messages every 2 seconds. What is probably a lot load on the server

And since the hosting is free i'm probably limited. So my database is crashing)

@Afrographics Better to use socket.io
Refresh based chat is so so 15 years old. You won't regret using sockets.

@themissingbrace it is supported by all hosting services?

@Afrographics You'll need a relay, which is often a separate service although it can be done over http. 0000webhost gives you a single apache vhost and a database on a shared MySQL instance. So either you use a different service for relaying or you use long-polling and the server waits for messages on, again, some kind of relay, although this time it could be an IPC-based relay. Now, I don't know about their security measures, but I feel like you don't have access to in-memory shared filesystem (/tmp) and you don't have exec() so you can't create a socket or something.
