Im on the last steps of finishing my project that has taken me almost a year. I had to learn how to use C++, Python, HTML and PHP by reading a lot of books. Now I just need to do one more thing and my project will be finished. The only thing is I am not sure if I have it in me to read two or three more books just do get one thing done. I have no experience with AJAX, JQUERY or JAVASCRIPT and it looks like that is what I need help with. I have spent days trying to decipher the Greek examples everyone has posted online.
So on my webserver I have a index.php (main file), a data.txt (data file) and a css file containing code for a temperature gauge 'tempGauge.css'
in my index.php file I use some php code to collect the data from 'data.txt' and I display it using a div containing all the calls to the tempGauge.css.
Everything works just fine but now I need to know how to periodically recollect the data in 'data.txt' and refresh the div containing the temp gauge. I have seen lots of examples online but none are clear and none are commented. I have no experience in javascript/ajax/jquery. Can anyone guide me thru the steps? Can anyone post any code with comments so I can understand what is going on? Also if there are scripts where do I add them to my index.php file? using 5 different languages in one file is too much for my head. Thanks to anyone who attempts to help me. You are the best!
NOTE: I intend to clean up the php with loops when everything is in working order
