php not updating sql database

Question

Hello I am running a server side database to process input from an android phone. I have two functions one to store the user information and one to update their location.

The second one to store location I cannot get to work.

   /**
 * Storing new user
 * returns user details
 */
public function storeUser($name, $email, $password) {
    $uuid = uniqid('', true);
    $hash = $this->hashSSHA($password);
    $encrypted_password = $hash["encrypted"]; // encrypted password
    $salt = $hash["salt"]; // salt
    $result = mysql_query("INSERT INTO users(unique_id, name, email, encrypted_password, salt, created_at) VALUES('$uuid', '$name', '$email', '$encrypted_password', '$salt', NOW())");
    // check for successful store
    if ($result) {
        // get user details 
        $uid = mysql_insert_id(); // last inserted id
        $result = mysql_query("SELECT * FROM users WHERE uid = $uid");
        // return user details
        return mysql_fetch_array($result);
    } else {
        return false;
    }
}

     /**
 * Updating a users
 * location
 */
public function updateLocation($email, $location) {
    $uuid = uniqid('', true);
    $result = mysql_query("UPDATE users SET location='$location' WHERE email='$email' NOW())");

    // check for successful store
    if ($result) {
        // get user details 
        $uid = mysql_insert_id(); // last inserted id
        $result = mysql_query("SELECT * FROM users WHERE email = $email");
        // return user details
        return mysql_fetch_array($result);
    } else {
        return false;
    }
}

Any help greatly appreciated.

Thanks

Answer 1

In looking at your update query $result = mysql_query("UPDATE users SET location='$location' WHERE email='$email' NOW())"); You appear to be missing part of it. You need to tell it what needs to be set to NOW(), perhaps updated_at, "UPDATE users SET location='$location', updated_at = NOW() WHERE email='$email'"

Answer 2

似乎你有一个错误：“ WHERE email='$email' NOW()) ”into“ created_at='NOW()' WHERE email='$email' ”

Answer 3

在SQL的末尾有一个额外的NOW（）
