php - 如何将 MySQL 数据库和用户从表单添加到配置文件

Question

我在 install/install.php 中有这个表单:

<form method="POST" action="installing.php" onSubmit="return validatedb();" id="installform">
    <div class="form">
        <div class="initem">
            <div class="dib name">Database Host</div>
            <div class="dib value"><input type="text" name="dbhost" value="<?= $preDbHost ?>" /></div>
        </div>
        <div class="initem">
            <div class="dib name">Database Name</div>
            <div class="dib value"><input type="text" name="dbname" value="<?= $preDbName ?>" /></div>
        </div>
        <div class="initem">
            <div class="dib name">Database User</div>
            <div class="dib value"><input type="text" name="dbuser" value="<?= $preDbUser ?>" /></div>
        </div>
        <div class="initem">
            <div class="dib name">Database Pass</div>
            <div class="dib value"><input type="text" name="dbpass" value="<?= $preDbPass ?>" /></div>
        </div>
    </div>
    <div class="stepper bbr">
        <div class="fll">Step 1/2 : Database Settings</div>
        <div class="flr"><input type="submit" value="Validate & Continue" class="btl bbr"/></div>
        <div class="cls"></div>
    </div>
</form>

在 inc/config.inc.php 中这段代码:

<?php

    // Error Reporting
    @error_reporting(E_ALL ^ E_NOTICE);


    /// Database Settings ///
    define('DB_NAME', '');          // MySQL database name
    define('DB_USER', '');          // MySQL database user
    define('DB_PASSWORD', '');      // MySQL database password
    define('DB_HOST', 'localhost');     // MySQL database host name (in most cases, it's localhost)


    if (isset($_SESSION['userid']) && is_numeric($_SESSION['userid']))
    {
        $userid = (int)$_SESSION['userid'];
    }

    define('Jobfia_ROOT', dirname(__FILE__) . '/');
    define('Jobfia_PAGE', TRUE);

    require_once(Jobfia_ROOT."db.inc.php");
    require_once(Jobfia_ROOT."functions.inc.php");

    if (!defined('is_Setup'))
    {
        require_once(Jobfia_ROOT."siteconfig.inc.php");
    }

?>

如何通过php在数据库设置的inc/config.inc.php中添加表单值，同时验证它们是否为真实值？

Answer 1

导入文件 inc/config.inc.php 在文件 install/install.php比

$DB_NAME
$DB_USER
$DB_PASSWORD
$DB_HOST

可以直接访问
