Question

因此，当我将信息放入我的注册表单时，该信息将不会转到phpmyadmin数据库...这是代码：

这是index.php文件：

<?php
   date_default_timezone_set('Europe/Copenhagen');
   include 'dbh.inc.php';
   include 'comments.inc.php';
   session_start();
?>

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Title of the document</title>
<link rel="stylesheet" type="text/css" href="style.css">
</head>

<body>
<!--Ovo je za login -->
<?php
   echo "<form method='POST' action='".getLogin($conn)."'>
      <input type='text' name='uid'>
      <input type='password' name='pwd'>
      <button type='submit' name='loginSubmit'>Login</button>
    </form>";
     echo "<form method='POST' action='".userLogout()."'>
      <button type='submit' name='logoutSubmit'>Log out</button>
    </form>";

    if (isset($_SESSION['id'])) {
        echo "You are logged in";

    } else {
        echo "You are NOT logged in!";
    }
?>
<!-- Ovo je za register -->
<?php

echo "<form action='signup.php' method='POST'>
      <input type='text' name='uid' placeholder='Username'><br>
    <input type='password' name='pwd' placeholder='Password'><br>
    <button type='submit'>SIGN UP</button>
</form>";
?>

<?php
echo "<form method='POST' action='".setComments($conn)."'>
     <input type='hidden' name='uid' value='Anonymous'>
     <input type='hidden' name='date' value='".date('Y-m-d H:i:s')."'>
     <textarea name='message'></textarea><br>
     <button type='submit' name='commentSubmit'>Comment</button>
</form>";

getComments($conn);
?>
</body>
</html>

这是comments.inc.php文件

<?php
function setComments($conn) {
    if (isset($_POST['commentSubmit'])){
        $uid = $_POST['uid'];
        $date = $_POST['date'];
        $message = $_POST['message'];

        $sql = "INSERT INTO comments (uid, date, message) VALUES ('$uid', '$date', '$message')";
        $result = mysqli_query($conn, $sql);
    }
}

function getComments($conn) {
    $sql = "SELECT * FROM comments";
    $result = mysqli_query($conn, $sql);
    while ($row = $result->fetch_assoc()){
    echo "<div class='comment-box'><p>";
          echo $row['uid']."<br>";
          echo $row['date']."<br>";
          echo nl2br($row['message']);
    echo "</p>

    <form class='delete-form' method='POST' action='".deleteComments($conn)."'>
                 <input type='hidden' name='cid' value='".$row['cid']."'>               
                 <button type='submit' name='commentDelete'>Delete</button>
             </form>

            <form class='edit-form' method='POST' action='editcomment.php'>
                 <input type='hidden' name='cid' value='".$row['cid']."'>
                 <input type='hidden' name='uid' value='".$row['uid']."'>
                 <input type='hidden' name='date' value='".$row['date']."'>
                 <input type='hidden' name='message' value='".$row['message']."'>
                 <button>Edit</button>
             </form>
    </div>";

    }
}

function editComments($conn) {
    if (isset($_POST['commentSubmit'])){
        $cid = $_POST['cid'];
        $uid = $_POST['uid'];
        $date = $_POST['date'];
        $message = $_POST['message'];

        $sql = "UPDATE comments SET message='$message' WHERE cid='$cid'";
        $result = mysqli_query($conn, $sql);
        header("Location: index.php");
    }
}

function deleteComments($conn) {
    if (isset($_POST['commentDelete'])){
        $cid = $_POST['cid'];

        $sql = "DELETE FROM comments WHERE cid='$cid'";
        $result = mysqli_query($conn, $sql);
        header("Location: index.php");
    }
}

function getLogin($conn) {
    if (isset($_POST['loginSubmit'])) {
    $uid = $_POST['uid'];
    $pwd = $_POST['pwd'];

    $sql = "SELECT * FROM user WHERE uid='$uid' AND pwd='$pwd'";
    $result = mysqli_query($conn, $sql);
    if (mysqli_num_rows($result) > 0) {
          if ($row = $result->fetch_assoc()){
              $_SESSION['id'] = $row['id'];
               header("Location: index.php?loginsuccess");
               exit();
         }  
     }else{
         header("Location: index.php?loginfailed");
         exit();

     }  
    }
}

function userLogout() {
    if (isset($_POST['logoutSubmit'])) {
        session_start();
        session_destroy();
        header("Location: index.php");
        exit();
    }
}

这是signup.php文件

<?php
include 'dbh.php';

$uid = $_POST['uid'];
$pwd = $_POST['pwd'];

$sql = "INSERT INTO user (uid, pwd)
VALUES ('$uid', '$pwd')";
$result = mysqli_query($conn, $sql);

header("Location: index.php");

dbh.php文件仅用于连接数据库

<?php
$conn = mysqli_connect("localhost", "root", "", "logintest");

if (!$conn){
     die("Connection failed: ".mysqli_connect_error()); 
}

//

<?php
   date_default_timezone_set('Europe/Copenhagen');
   include 'dbh.inc.php';
   include 'comments.inc.php';
?>

以及editcomment.php文件：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Title of the document</title>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>

<?php
$cid = $_POST['cid'];
$uid = $_POST['uid'];
$date = $_POST['date'];
$message = $_POST['message'];

echo "<form method='POST' action='".editComments($conn)."'>
     <input type='hidden' name='cid' value='".$cid."'>
     <input type='hidden' name='uid' value='".$uid."'>
     <input type='hidden' name='date' value='".$date."'>
     <textarea name='message'>".$message."</textarea><br>
     <button type='submit' name='commentSubmit'>Edit</button>
</form>";
?>

</body>
</html>

好的，我认为问题可能在于放置了注册表单的index.php文件或signup.php文件，但我不知道如何修复它。

我输入注册表的信息不会输入mysql数据库
