Php, javascript and Css

csam0003

Hi all,

Your thoughts on the scenario I have at the moment would be greatly appreciated.
Currently I have a php file which depending on some condition sets a variable in the response header to true or false.
I then have an xsl template that contains some javascript which checks whether the variable is set to true or false (jquery.post). Depending on the result, if its on I use some jquery to add a particular class to a particular div tag and if its off I remove a particular css class from a div tag. I also apply some javascript depending on the condition.

This is done for every page load. Can I somehow do this all in php which runs on the server side every 5 minutes instead of taxing the client every page refresh?

If yes, how can this be done?

Thanks as always

could you be more specific as to why this is done? what are you trying to achieve?

Thanks Dagon for your reply.

So my situation is this. My website used a third party chat system. On my website I have a widget that checks whether this third part chat system is online or offline (true or false). This is done through an xsl template that contains some javaascript that calls this php file.


 jQuery.post( 'http://www.mywebsite.com/workingspace/check-chat.php', {}, function(response){
		 if (jQuery.trim(response) == 'online') {
		 if (jQuery('#live-chat-form').hasClass('auto-open')) {
		 jQuery('#live-chat-form').slideDown();
		 }
		 jQuery('a.live-chat')
		 .removeClass('offline')
		 .addClass('online')
			 } else {
		 jQuery('a.live-chat')
		 jQuery('#live-chat-form').remove();
		 }
		 })

So as you can see depending on the response, the widget changes its color depicting whether its online or offline. This is done through adding a css class and removing.
I would like to do all this on the server side. So every 5minutes a check would be made to see if the chat system is online or offline, and depending on this the jquery actions aobve are applied.
