php - How to check if something is fetched , and then to run multiple query -


i've searching quite time no luck. want check if given username , password correct echo something, it's not working. after want run query.

<?php     require "conn.php";     $status=1;     $user_name = $_post["user"];     $user_pass = $_post["pass"];      $sql = "select * tbl_client username = :user , password = :pass";     $sth = $dbl->prepare($sql);     $sth->execute(array(':user => $user_name' , ':pass => $user_pass' ));     //$sth->execute(':user' => $user_name, ':pass' => $user_pass);      $row = $sth->fetch(pdo::fetch_num);     if ($row) {         echo 'login success , hello';     } else {         echo 'login failed';     }      $sql = 'insert login_status (username, status) values (:user, :status)';     $sth = $dbl->prepare($sql);     $sth->execute(array(':user => $username' , ':status => $status' )); ?> 

$sth->execute(array(':user => $username' , ':pass => $user_pass' ));

that wrong! array contains 2 strings should contain 2 key-value pairs (key = parameter in sql query, value = want pass database driver)

try this

    $sth->execute(array(':user' => $username , ':pass' => $user_pass ));
