我正在关注 this在 windows7 上使用 XAMPP 的 php 教程。
这是一个留言簿教程，将用户条目保存到 mysql 中并显示来自 db 的条目。当我在表单中输入数据并提交时，浏览器显示此错误消息

Connect to DB Code

<?php
$dbHost = "localhost";
$dbUser = "root";
$dbPass = "";
$dbDatabase = "myDB";

// Connect to DB

$li = new mysqli('localhost', 'root', '', 'myDB') or 
      die("Could not connect". mysqli_connect_error());
//mysql_select_db($dbDatabase, $li) or 
      die ("could not select DB". mysql_error());
?>

Variables initialisation

<?php
// initiate some vars

$gb_str = "";   
// $gb_str is the string we'll append entries to
$pgeTitle = "View and Sign Guestbook";

Post request handling

// If form is submitted, then insert into DB
if (!empty($_POST["submit"])) {
    $name = $_POST["frmName"];
    $email = $_POST["frmEmail"];
    $comment = $_POST["frmComment"];
    $date = Date("Y-m-d h:i:s");

    $gb_query =     "insert into guestbook
            values(0, '$name', '$email', '$comment', '$date')";
    // Performs the $sql query on the server to insert the values
    if ($li->query($gb_query) === TRUE) {
        echo 'users entry saved successfully';
    }
    else {
        echo 'Error: '. $li->error;
    }
    /*
    $sql = mysql_query($gb_query);
    $res = mysql_affected_rows($sql);

    // See if insert was successful or not
    if($res > 0) {
        $ret_str="Your guestbook entry was successfully added.";
    } else {
        $ret_str = "Your guestbook entry was NOT successfully added.";
    }

    // Append success/failure message
    $gb_str .= "<span class=\"ret\">$ret_str</span><BR>";
    */
}
?>

GuestBook list

<?php

$get_query = "select gbName, gbEmail, gbComment, 
              DATE_FORMAT(gbDateAdded, '%m-%d-%y %H:%i') gbDateAdded
              from guestbook";

$result = $li->query($get_query);
$gb_str .= "<hr size=\"1\">";

if ($result->num_rows > 0) {
    // output data of each row from $result
    while($row = $result->fetch_assoc()) {
    $name = $row["gbName"];
    $email = $row["gbEmail"];
    $comment = $row["gbComment"];
    $date = $row["gbDateAdded"];

    if(!empty($name)) {
        // If name exists and email exists, link name to email
        if(!empty($email)) {
            $name="by <a href=\"mailto:$email\">$name</a>";
        }
    // If name does exist and email exists, link email to email     
    } else if (!empty($email)) {
        $name = "by <a href=\"mailto:$email\">$email</a>";
    } else {
        $name = "";
    }

    // Append to string we'll print later on
    $gb_str .= "<br>$comment<p class=\"small\">
                posted on $date $name<hr size=\"1\">";
}}

?>

最佳答案

第二个问题回答，你没有将查询结果分配给变量并且 mysql_affected_rows 也是空的。

$gb_query =     "insert into guestbook
        values(0, '$name', '$email', '$comment', '$date')";

$sql = mysql_query($gb_query);
$res = mysql_affected_rows($sql);
