php - How do I update my database with mysqli and javascript -

-

i have website audioplayer , integrated lyricviewer on screen, user should able sync music hear playing. have 1 problem, , is; how on earth i, javascript function, call mysqli update statement? when user clicks save button, content gets thrown div, want php after javascript has been run take content , put database.

what best way that?

why doesn't work?

        function saveinphp() {         //alert("came here");         //var superstr = $( "#savelyric" ).text();         var superstr = 'lol';         $.ajax({         type: "post",         url: "includes/sendlyrics.php",         data: superstr,         cache: false,         contenttype: false,         processdata: false,         success:  function(data){             alert("---"+data);             alert("settings has been updated successfully." + data + "~~~" + superstr);             //window.location.reload(true);         }     });     }

and php:

    <?php  include ('db_connect.php');  $data = $_post['data'];      $query = "update song set time=". $data ." id='1'";     mysqli_query($query); ?>

write php in totally separate dedicated file takes post variables, constructs sql query, , inserts them database. have javascript function send data php file using post request.

javascript in browser cannot interact database. can send get/post requests server can catch requests , put attached data database.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
