$25-50 USD / hour

I need help with PHP-MYSQL-AJAX-JAVASCRIPT fom time to time. This would be a get-paid to be a teacher type of project and eventually maybe be a partner doing some projet part or whole project. Here is my problem: I have a web page generated with PHP with a repport <div> on it. the department manager want this repport to be refreshed every 5 seconds.... for maybe 5-10 person looking at it in real time. the page it filled with content and by itself it makes maybe 20 to 30 MySql query to output de page. I am afraid that refreshing the page every 5 sec will load the Mysql Server with tons of similar request over and over.... I track the last change in a Mysql Table in [login to view URL] then refresh only the repport table div if the returned value form the Ajax request have changed.. I tried different ways but my knowledge of javascript & Jquerry are insuffisant to make it work. I don't kno how to store the return value of '[login to view URL]' and than 5 second later compare it to the new value of '[login to view URL]' en if changes then reload '[login to view URL]

I read your question but would need further info so we are on same page. One of the solution to your issue I see is if all students using same data than we can use on file for storing the data which is accessed by all students or if they are accessing different data then we need to use approach like yours. But all would be much clear after discussion. I am available for chat and work right away. Have 7 years of experience so be assured of the work

Hey there, I can help you with this. From what I understand you are saying you want to introduce a AJAX request to allow you to minimize processing on your server; currently to refresh the page, all of the ~20 MySQL queries would have to be rerun every 5 seconds. You want a way to just rerun the queries that are needed to be refreshed.
