I want to limit the click of a button to 1 click per computer. Is it possible?
Code so far:
<html>
<body>
<br><br>
<a style="color: grey; background-color: #fff; font-family: Arial; text-decoration: none; padding: 25px 50px; border-radius: 3px;" href="http://hugovales.esy.es/likeme/download_arquivo.php">I Like!</a>
<br><br><br><a style="color: #fff; font-family: Arial;"><? include "contador_arquivo.txt"; ?> People Enjoy it</a>
</body>
</html>
Oops, use this javascript:
var createCookie = function(name, value, days) {
var expires;
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
expires = "; expires=" + date.toGMTString();
}
else {
expires = "";
}
document.cookie = name + "=" + value + expires + "; path=/";
}
function getCookie(c_name) {
if (document.cookie.length > 0) {
c_start = document.cookie.indexOf(c_name + "=");
if (c_start != -1) {
c_start = c_start + c_name.length + 1;
c_end = document.cookie.indexOf(";", c_start);
if (c_end == -1) {
c_end = document.cookie.length;
}
return unescape(document.cookie.substring(c_start, c_end));
}
}
return "";
}

After this you can create a function in the click of the link:
<a style="color: grey; background-color: #fff; font-family: Arial; text-decoration: none; padding: 25px 50px; border-radius: 3px;" href="http://hugovales.esy.es/likeme/download_arquivo.php" onclick=" return check()">I Like!</a>
then create a function to validate:
function check(){
check = getCookie('isclique');
if(check){
return false;
}
createCookie('isclique','true',100);
}
Something of the genre. I hurried. But this validation is not 100%, the "only" 100% way that is still to cheat but is more secure than this, would validate in the backend.
