localhost上的php錯誤：禁止訪問！錯誤403

Question

我正在使用XAMPP在windows7上關注這個 php教程。
這是一本留言簿教程，可以將用戶條目保存到mysql中並顯示db中的條目。 當我將數據輸入表格並提交時，瀏覽器顯示此錯誤信息

連接到DB代碼

<?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());
?>

變量初始化

<?php
// initiate some vars

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

發布請求處理

// 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);

    // See if insert was successful or not
    if($res > 0) {

    } else {
        $ret_str = "Your guestbook entry was NOT successfully added.";
    }

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

Answer 1

第二個問題回答，你沒有將查詢結果分配給變量， 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);

Answer 2

聽起來這個錯誤是由阻塞目錄的Xampp配置引起的。 如果您在開發計算機上並且不關心安全性，請在xampp下的apache / conf目錄中查找名為httpd.conf的文件。

你會在那里找到類似的指令

<Directory />
    Options FollowSymLinks
    AllowOverride none
    Order deny,allow
    Allow from none
    Deny from all
</Directory>

用它替換它

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    Deny from none
</Directory>

這使得根驅動器上的每個文件都可以被Web服務器訪問，這在開發機器上是可以的（盡管有些人肯定會爭論這一點），但在生產中根本不是一個好主意。
