使用php通過wordpress在mysql數據庫中添加一個新行

Question

我在這方面很新，我在使用wordpress時遇到了一些問題。

我試圖將一些信息插入到mysql數據庫中。 因此，我正在做以下事情：

首先我在wp-content/plugins/my-codes創建了一個php文件，文件名是insertUser.php，我添加了以下代碼：

<?php
require_once('../../../wp-config.php');
global $wpdb;
$table_name = $wpdb->prefix . "Users";
$name=addslashes($_POST['sName']);
$email=addslashes($_POST['sEmail']);
$wpdb->insert( $table_name, array( '$name','$email' ) );
?>

然后我用以下內容創建了一個基本頁面：

<form action="/wp-content/plugins/my-codes/insertUser.php" method="post">
Name: <input type="text" name="sName" />
Email: <input type="text" name="sEmail" />
<input type="submit">
</form>

現在的問題是，當我填寫表單並按下提交按鈕時，將我重定向到http://www.example.com/wp-content/plugins/my-codes/insertUser.php而不是檢查任何一行數據庫。

我做錯了什么想法？

謝謝！

代碼編輯

<form action="/wp-content/plugins/my-codes/insertUser.php" method="post">
Name: <input type="text" name="sName" />
Email: <input type="text" name="sEmail" />
<input type="submit" name="submit">
</form>

Answer 1

嘗試跟進下面的代碼，它會將日期插入數據庫，檢查wp-config.php是否只有三個文件夾，其他所有你可以從這里復制粘貼。

我在同一頁面中完成了插入編碼，您可以復制粘貼代碼，以便單獨插入到您喜歡的頁面中。

<?php 
include '../../../wp-config.php';
global $wpdb;    
if(isset($_POST['submit']))
{
    $name=addslashes($_POST['sName']);
    $email=addslashes($_POST['sEmail']);
    $wpdb->insert("test",array(
        "sName"=>$name,
        "sEmail"=>$email,
        ));
}    
?>   
<form action="" method="post">
Name: <input type="text" name="sName" />
Email: <input type="text" name="sEmail" />
<input type="submit" name="submit">
</form>

Answer 2

感謝@Naresh Kumar.P的幫助。 必須使用數據庫的憑據更改配置文件以使代碼工作。

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'yourDataBaseName');

/** MySQL database username */
define('DB_USER', 'YourDataBaseUserName');

 /** MySQL database password */
define('DB_PASSWORD', 'YourDataBasePassword');

/** MySQL hostname */
define('DB_HOST', 'localhost');

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');

/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');

就是這樣。 代碼是正確的！

謝謝！
