Looks awesome, however makes me worried about performance: wouldn't such a dense request attack kill the server? (I'm very much an amateur, so might be completely irrelevant question :) Thanks a lot!

Thanks!!! this is a great tutorial :) You are an amazing developer. I have a question: How do I make that the scroll animation works only if the user is at the bottom of the chat? To avoid annoying scrolls while reading earlier messages?

Great tutorial.. but i have a question if i want to insert the date in the middle of the chat, the date of the discussion do you know how can i do that?

how to add notifications when a message received ? Is possible and active status (online/offline) of the users?

[alexandrecarvalho]

Thanks for this awesome video ! I feel sorry for you that after all of this, you got plenty of comments requesting the code while they could just watch and copy...
This is my first time using Ajax, but I see a problem using this method : my cpu temperature went from 60°C to 90°C because of XHR looping. I saw that we could maybe use setTimeout instead, wouldn't it be a better compromise for real usage ?


EDIT :
i found out how to set a time interval for data reloading : remove the "load();" line inside load() function and replace the "load()" inside $(document).ready function with ->
setInterval(function () {
load();
}, 500);

replacing 500 with the value that you want of course

great tutorial, but i didn't understand why the messages are updated automatically on user 2 when the user 1 sends message .

[miguelangelcuapa]

Buen código, nada complicado de entender y simple. Gracias por compartir.

Instead of selecting all the messages every time... You should poll and select the last message only if it has not already been selected. :) O(n) vs O(1) - or just use web sockets and create a room if it hasn't already been created based off of the chat id stored in the db. /:

[samuelassmann]

Hey i like this Video but i have a problem with the sqldatabase. I implementet it like you and it dont works. So mayby there is a problem with a new sql Version or with jquery.

[alexdevorigin]

XHR socket se tilda si abro la consola, pero si no la abro sigue normal, como puedo limitar las peticiones tan rapidas que hace el socket?

[sufyankhanbest]

@microcode every time we are fetching complete database results even after refreshing the page... how do we start new chat after refreshing the page without fetching database previous results... PLEASE PLEASE PLEASE respond me.

why doesn't scrollHeight work when adding to (session_user)?
