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：
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')")) {

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
}
}
