如何在 .htaccess 文件中添加错误页

下面是我的.htaccess文件。我有一个default_rewrite.php文件，我从我创建的数据库中获取我的内容。

RewriteEngine on
RewriteRule ^/?([a-z0-9-_]*)$ default-rewrite.php?page=$1 [L]

当您转到已知的断开链接时，例如http://www.example.com/test/fgdhfuis它会转到我的默认重写页面，但不会转到我存储在数据库中的页面。例如

http://www.example.com/test/home

我已经尝试过ErrorDocument 404 /404.php但这不适合我。

任何建议将不胜感激。

在 PHP 编辑下方：

<?php
  if (!function_exists("GetSQLValueString")) {
  function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
  {
  if (PHP_VERSION < 6) {
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }
  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
  switch ($theType) {
  case "text":
  $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
  break;    
  case "long":
  case "int":
  $theValue = ($theValue != "") ? intval($theValue) : "NULL";
  break;
  case "double":
  $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
  break;
  case "date":
  $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
  break;
  case "defined":
  $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
  break;
  }
  return $theValue;
  }
  }
  $colname_Page = "home";
  if (isset($_GET['page'])) {
  $colname_Page = $_GET['page'];
  if($colname_Page == "")
  $colname_Page = "home";
  }
  mysql_select_db($database_VRMOnline, $VRMOnline);
  $query_Page = sprintf("SELECT * FROM Page WHERE PageName = %s", GetSQLValueString($colname_Page, "text"));
  $Page = mysql_query($query_Page, $VRMOnline) or die(mysql_error());
  $row_Page = mysql_fetch_assoc($Page);
  $totalRows_Page = mysql_num_rows($Page);
  mysql_select_db($database_VRMOnline, $VRMOnline);
  $query_MetaData = "SELECT * FROM MetaData WHERE MetaDataID = 1";
  $MetaData = mysql_query($query_MetaData, $VRMOnline) or die(mysql_error());
  $row_MetaData = mysql_fetch_assoc($MetaData);
  $totalRows_MetaData = mysql_num_rows($MetaData);
  ?>

我试过了

  $colname_Page = "home";
  if (isset($_GET['page'])) {
  $colname_Page = $_GET['page'];
  if($colname_Page == "")
  $colname_Page = "home";
  if ($totalRows_Page == 0)
  {
  $colname_Page = "404-error";
  }

但这会使每个页面都进入 404 错误
