我认为如果结果问题我怎么修复？我想如果用户名=用户名和pw登录。

Answer 1

改变这个：

$query = $db->prepare("SELECT * FROM user WHERE 
    username = :userg,
    pw = :pwg");
    $result = $query->execute(array(
    'userg' => $_POST['userg'],
    'pwg' => $_POST['pwg'],
    ));

对此：

$query = $db->prepare("SELECT * FROM user WHERE 
    username = :userg AND pw = :pwg");
    $query->bindParam(':userg', $_POST['userg']);
    $query->bindParam(':pwg', $_POST['pwg']);
    $query->execute();

感谢Fred-ii-在select查询中捕获我的错误！变化：

if($result > 0){
        echo "ok";
    }else{
        echo "no";
    }

致：

$count = $query->rowCount();
if($count==1){
echo "ok";
    }else{
        echo "no";
    }

Answer 2

尝试此查询[SELECT * FROM user WHERE username =：user AND pw =：pw]

＆＃13;

if($_POST['giris']){

$req = $bdd->prepare('SELECT * FROM user WHERE username = :user AND pw = :pw');
$req->execute(array('user' => $_POST['userg'], 'pw' =>  $_POST['pwg'] ));
   
    if($result > 0){
        echo "ok";
    }else{
        echo "no";
    }
 }
