Question

how to clear the cache and auto reload page in a given time in yii framework ?
like e.g in the next 5 hours, the content of the page should change prior to clear cache then reload the page

$time = date('h:i:s A', strtotime("+5 hours"));

and then in the next 5 hours, it will clear cache again and reload the same page and show new content

Answer 1

If i understand well the question.

In the Yii view that your are, add something like this in javascript

<script>
 setTimeout(function(){ window.location = "<URL>";}, 5*60*1000);
</script>

this is a redirect after 5 minutes. if you want 5 hours just use

300*60*1000

and point the URL to http://www.example.com/controller/action you want.

If still you wanna do it in php i believe you can add this line to your view.

<?php header("Refresh: 18000; URL=http://www.example.com/controller/action"); ?>

here 18000 is in seconds.

Hope it helps.

but if you are only updating small bits of the view.. why not create a timer to make ajax request to the controller/action you want to update the data from? Yii is ready for that kind of need.
