无法更新数据库值

Question

这是我的代码。我想更新我的数据库值。但它不起作用。 我想更新状态从（待定）到（借用）AND从（returnP）更新到（返回）。

这是代码：

if(isset($_GET['gate']))
{
    extract($_GET);
    $timestamp=date("d/m/y h:i:sA",time());
    $sql = "SELECT *FROM rent_record WHERE pass_open='$gate'";
    $result = $conn->query($sql);
    $row = mysqli_fetch_array($result);
    $name = $row["ID"];
    $status = $row["status"];


    if (($gate==$name) AND ( $status=='pending'))

    {       
    $sql = "UPDATE rent_record SET status='borrowed' WHERE ID='$name';";
    if ($conn->query($sql) === TRUE) header('Location: '.BASE_URL.'/keypad');
    else echo "Error: " . $sql . "<br>" . $conn->error;     

    $sql = "UPDATE rent_record SET time_taken='$timestamp' WHERE ID='$name';";
    if ($conn->query($sql) === TRUE) header('Location: '.BASE_URL.'/keypad');
    else echo "Error: " . $sql . "<br>" . $conn->error;     
}
else if (($gate==$name) AND ( $status=='returnP'))
{   
    $sql = "UPDATE rent_record SET status='returned' WHERE ID='$name';";
    if ($conn->query($sql) === TRUE) header('Location: '.BASE_URL.'/keypad');
    else echo "Error: " . $sql . "<br>" . $conn->error;     

    $sql = "UPDATE rent_record SET time_return='$timestamp' WHERE ID='$name';";
    if ($conn->query($sql) === TRUE) header('Location: '.BASE_URL.'/keypad');
    else echo "Error: " . $sql . "<br>" . $conn->error; 
}
}
else
{
    header("Access-Control-Allow-Origin: *");
    header("Content-Type: application/json; charset=UTF-8");

    $sql = "SELECT pass_open, pass_closed FROM rent_record WHERE status='pending' OR status='returnP'";
    $result = $conn->query($sql);

    $outp = '[';
    while($rs = $result->fetch_array(MYSQLI_ASSOC))
    {
        if ($outp != '[') {$outp .= ',';}
        $outp .= '{"ID":"' . $rs['ID'] . '",'; 
        $outp .= '"password":"' . $rs['pass_open'] . '"}'; 
        $outp .= '"password":"' . $rs['pass_closed'] . '"}'; 
    }
    $outp .=']';

    echo($outp);
}   

希望有人可以帮助我。先谢谢你。
