Contiuous Refresh

[almightyegg]

I waswondering how I would make a certain part of the page update every second, to check whether new messages are in the database. I know how I can post messages to the database without refreshing, but it's just showing them afterwards without a page reload that I can't do. Can anyone point me to a tutorial or help with it temselves? TY in advance

Probably the only way of doing this is using the Javascript to run a function every 1sec, then have the JS function use ajax to call a php file which you can check to see if there is any new update. Then load whatever you found into a div or span tag on your page.

 

JS file

function checkMessages(){

sendRequest('checkNewMessages.php','newMessages');

setTimeout("checkMessages", 1000);
// Param 1 = "checkMessages" will call this function
// Param 2 = 1000 milli = 1 sec
}

 

PHP FILE

do whatever you need to do
