all. I want to share some issue that happen in my code. I have a HTML form that posted and saved to mysql database using php. I give a validation form if the total of data isn't 100, it can't posted. I do this restriction in client side or HTML using javascript. something like this :
$("#submit").click(function(event) {
var total_I = $("#total_I").val();
var total_III = $("#total_III").val();
var total = 0;
/* stop form from submitting normally */
if($("#eval-form").validate().form())
{
it works perfectly when we do some test plan. But when this website is launched and accessed approximately 500 user in a time, there is some data that have data less than 100 saved in database. My question is, How to overcome this problem? Is there any method to restrict this condition better ? first, thanks to your answers
