Question

我有一个简单的消息和用户数据库。消息包含id，消息和创建日期。我试图在人们点击提交消息之后将这些放入数据库但我得到了一些问题，无论是谁投入，每次都给我0，0-0-0为日期创建。我正在使用的两个代码文件就是这个。

<?php
    session_start();

    include "validate.php";
    include "src/header.php";
    include "src/mainmenu.php";
?>
    <form method="post" action="message_action.php">
    <fieldset>
    <legend>Message Area</legend>
    <p>
        <label for="message">Message:</label> <textarea name="message" id="message" rows="5" cols="50"></textarea>

    <p class="center"><input value="Send" type="submit" /></p>
    </fieldset>
    </form>

    <p><a href="exit.php">Exit</a></p>
<?php   
    include "src/footer.php";
?>

<?php
    session_start();
    include 'db.php';

    $id_user = $_SESSION['id']; 
    $message = $_POST['message'];

    $sql = "INSERT INTO messages (id_user, message) VALUES ('$id_user','$message');";
    $result = mysqli_query($link, $sql);
    mysqli_close($link);

    if ($result == false) {
        include "src/header.php";
        include "src/mainmenu.php";
        echo '<p>Error: cannot execute query</p>';
        echo '<p><a href="register.php">Try again</a></p>';
        include "src/footer.php";
        exit;
    }
    else {
        header('Location: private.php');
    }
    mysqli_close($link);
?>

创建日期现在有效，但仍然是获取id_user的问题。
