Question

我的页面上出现了一个我无法识别的错误，当我在线查看该网站时，它会将所有网站内容替换为值＆＃34; 0＆＃34;。为什么我看不到表单，是否正确地与SQL服务器通信？

PS：登录正常，会话已创建，因此connect.php可以正常运行。

以下是members.php的代码：

<?php 
// starting session
session_start();

// check if user is logged in
if (!isset($_SESSION['username']))
{
    header('Location: http://wwww.gjertgjersund.com/');
    exit();
}
else
{
    // database connection
    require ('connect.php');

    //post record count
    $post_count = mysql_query("SELECT * FROM posts");
    $post_count_result = mysql_num_rows($post_count);

    //comment count
    $comment_count = mysql_query("SELECT * FROM comments");
    $comment_count_result = mysql_num_rows($comment_count);

    if(isset($_POST['submit']))
    {
        $newcategory = $_POST['newcategory'];
        if(!empty($newcategory))
        {
            $query = mysql_query("INSERT * INTO categories (category) VALUES ('$newcategory')";
            if($query)
        {
            echo 'New category added';
        }
        }
        else
        {
            echo 'Error';
        }
    }
    else
    {
        echo 'Missing newcategory';
    }
}
?>

Answer 1

$query = mysql_query("INSERT * INTO categories (category) VALUES ('$newcategory')";

应该是

$query = mysql_query("INSERT INTO categories (category) VALUES ('$newcategory')";

为什么我的表单被echo“0”替换？
