为什么我的PHP代码会干扰我的AJAX代码？
当我提交一个名为为什么我的PHP代码会干扰我的AJAX代码？,php,ajax,Php,Ajax,当我提交一个名为functions\u question2的表单时，我有以下PHP代码来更新mySql数据库： $id = $_SESSION['id']; if(isset($_POST['functions_question2'])){ if($id){ $res3 = $db->query("SELECT * FROM answers WHERE user_id=$id"); $data3 = $res3->fetch_array();

if(isset($_SESSION['functions_question2']) && $_POST['functions_question2']==$_SESSION['functions_question2']){
$db->query("UPDATE answers SET FunctionsScore = FunctionsScore+1 WHERE user_id=$id");
