实现一个基于Ajax的调查程序_PHP教程

(做为现在的主流开发语言)

global $db;

$poll = $db->getRow("select * from TBL_POLL order by poll_id desc limit 1");
$poll_id = $poll["poll_id"];
$pollitems = $db->getAll("select * from TBL_POLLITEM where poll_id=$poll_id");
?>

服务器端

function poll($formData){
global $db;
$tmp="";
$objResponse = new xajax(动态网站静态化)Response();

$poll_id = $formData[poll_id];
$pollitem_id = $formData[pollitem];

if($pollitem_id > 0 && $poll_id > 0) {
$db->query("update ".TBL_POLLITEM." set count=count+1 where pollitem_id = $pollitem_id");
}

$poll = $db->getRow("select * from TBL_POLL where poll_id = $poll_id");
$pollitems = $db->getAll("select * from TBL_POLLITEM where poll_id=$poll_id");


$tmp .="".$poll["title"]."
";
for ($i = 0, $count = count($pollitems); $i < $count; $i++) {
$tmp .="".$pollitems[$i][content].": ".$pollitems[$i][count]."";
