我对你的问题很简单...... :-) 我想将数据插入到数据库中，该数据库有2个表，一个是用户，第二个是userprofile

这是我的db：

streams

如您所见，我有外键用户 - ＆gt; id with userprofile-＆gt; userid 问题是，当我想要注册新用户时，我不能.... 但是当我没有外键时，那一切都还可以。 但我需要注册外键她是register.php代码希望你能骗我:-) 并且请求告诉我代码的例子是我犯了错误。

<?php
session_start();
if (isset($_SESSION['user']) != "") {
    header("Location: home.php");
}
include_once 'dbconnect.php';

if (isset($_POST['btn-signup'])) {

    $y = $_POST['yer'];
    $m = $_POST['month'];
    $d = $_POST['day'];
    $dob = $d.'-'.$m.'-'.$y;

    $uname = mysql_real_escape_string($_POST['uname']);
    $upass = md5(mysql_real_escape_string($_POST['pass']));

    $email = mysql_real_escape_string($_POST['email']);
    $fname = mysql_real_escape_string($_POST['fname']);
    $lname = mysql_real_escape_string($_POST['lname']);
    $country = mysql_real_escape_string($_POST['country']);
    $height = mysql_real_escape_string($_POST['height']);
    $hair_color = mysql_real_escape_string($_POST['hair_color']);
    $eye_color = mysql_real_escape_string($_POST['eye_color']);
    $Body_type = mysql_real_escape_string($_POST['Body_type']);
    $gend = mysql_real_escape_string($_POST['gend']);

    if (mysql_query("INSERT INTO users(Username,Pasword) VALUES('$uname','$upass')") &&
        mysql_query("INSERT INTO userprofile(gender, dateofbirth, firstname, Lastname, height, eyecolor, haircolor, bodytype, country_town, email) VALUES ('$gend','$dob' ,'$fname','$lname','$height','$eye_color','$hair_color','$Body_type','$country','$email')")) {
?>

        <script>alert('successfully registered '); </script>

                    <?php
        $_SESSION['user'] = $row['id'];
        header("Location: Index.php"); ?>



        <?php
        $_SESSION['user'] = $row['id'];
        header("Location: Index.php");
    }
    else {
?>
        <script>alert('error while registering you...');</script>
        <?php
    }
}
?>

请改为尝试：

if (mysql_query("INSERT INTO users(Username,Pasword) VALUES('$uname','$upass')") &&
        mysql_query("INSERT INTO userprofile(
                    gender,
                    dateofbirth,
                    firstname,
                    Lastname,
                    height,
                    eyecolor,
                    haircolor,
                    bodytype,
                    country_town,
                    email,
                    userid)
        VALUES (
                    '$gend',
                    '$dob',
                   '$fname',
                    '$lname',
                    '$height',
                    '$eye_color',
                    '$hair_color',
                    '$Body_type',
                    '$country',
                    '$email',
                    last_insert_id()
         )")) {

注意到“last_insert_id（）”值和添加的“userid”列名称。

答案 1 :(得分：1)

我建议您只使用一个表来存储有关用户，密码和所有信息的信息。

例如：

   $sql = "insert into user (username,email,password,acctype) values ('$uname','$email','$password_hash','$acctype')";
   $result = mysqli_query($conn,$sql);

然后，当用户执行certian事项时，您可以使用用户ID跟踪该事件。这意味着对于每个操作，您需要在该表中将用户ID作为外键发布。

   $sql = "select * from bookings WHERE uid ='".$_SESSION['user_id']."' order by id desc limit 15";
   $result = mysqli_query($conn,$sql);

然后你可以根据session或uid选择...

答案 2 :(得分：0)

好的，我找到了方法

我修改了这样的代码：

if (mysql_query("INSERT INTO users(Username,Pasword) VALUES('$uname','$upass')")) {

    //$sql="select id from users";
    $test=mysql_result(mysql_query("SELECT id FROM users LIMIT 1"),0);
    if (mysql_query("INSERT INTO userprofile(userid,gender, dateofbirth, firstname, Lastname, height, eyecolor, haircolor, bodytype, country_town, email) VALUES ('$test','$gend','$dob' ,'$fname','$lname','$height','$eye_color','$hair_color','$Body_type','$country','$email')"))
     {

        ?>

        <script>alert('successfully registered '); </script>

        <?php
        $_SESSION['user'] = $row['id'];
        header("Location: Index.php"); ?>


        <?php
        $_SESSION['user'] = $row['id'];
        header("Location: Index.php");
    } else {
        ?>
        <script>alert('error while registering you...');</script>
        <?php
    }
}
