I'm using codeigniter and I have a timeout function using jquery. I just need to find a way to get a number (an int) from a field in the database the application is using and set the initial int in the javascript file to it. As you can see in the code '900000' needs to be dynamically received from a database table. Since it does not need ajax(does not need dynamically receive data in real time) I would like to find a lighter solution if possible. What would be the best practice in this situation?
$(document).ready(function () {
idleTimer = null;
logoutTimer = null;
idleWait = 900000; //15 minutes
logoutWait = 30000; //30 sec
timeUp = false;
Just use echo to output the value at that point in the script.
idleWait = <? echo $timeoutValueRetrievedFromDataBase ?>;
PHP will not run in your standard JS file without quite a bit of modification. First off, find the .php file where your <head> section is located. Find the first <script> tag, you will want to work before this. That way you can go ahead and set a variable that will be ready when your JS file gets loaded.
Right above your first <script> tag insert something like this
<script>
<?php
//you will need to connect to db here and get your timeout value from the database
//we assume $timeout has the correct value in it
echo "var phpTimeout = $timeout;"
?>
</script>
You would then go into the script you pasted into the question and do this
$(document).ready(function () {
idleTimer = null;
logoutTimer = null;
idleWait = phpTimeout; //this is the variable we set earlier in the <head> of the document
logoutWait = 30000; //30 sec
timeUp = false;
