我正在尝试将当前连接的用户名的 ID 插入数据库，如何从查询中获取我的用户名的 ID？ 我正在尝试将新行插入数据库并需要连接的用户的 ID。
<?php
require 'connect.inc.php';
require 'core.inc.php';
?>
<?php
$username = "";
if(isset($_POST['username'])&&isset($_POST['password'])){
$username = $_POST['username'];
$password = $_POST['password'];
if(!empty($username)&&!empty($password)){
$query = "SELECT `id` FROM `auth_user` WHERE `username`='$username' AND `password`='$password'";
echo $query;
if($query_run = mysqli_query($connect, $query)){
$query_num_rows = mysqli_num_rows( $query_run);
if($query_num_rows==0){
echo 'Invalid username/password combination.';
}else if ($query_num_rows==1){
$_SESSION['username']=$username;
$_SESSION['password']=$password;
$_SESSION['id']=$query_num_rows;
header('Location: main.php');
}
}
}else{
echo 'You must supply a username and password.';
}
}
if(isset($_POST["Submit"])){
if(isset($_POST["ch1"])){
setcookie("unm",$_POST["username"],time()+3600);
setcookie("pwd",$_POST["password"],time()+3600);
}
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
Username: <input type="text" name="username"><br><br>
Password: <input type="password" name="password"><br><br>
<input type="submit" value="Login"><br><br>
<input type= "checkbox" name="ch1" value="ch" />Remember username and password <br><br>
<a href="removename_password.php">Remove username and password</a><br><br>
最佳答案
像这样，如果 ID 存储所选记录的 id:
if ( $row = mysql_fetch_assoc( $query_run )) {
$userID = $row["ID"];
}
