【问题描述】:
我自己解决了这个问题。文件名错误lolz。
大家好!
我正在构建一个像 Drupal 和 Joomla 这样的 CMS。我正在开发模块功能(插件),但出现以下错误:
Fatal error: Class 'settings' not found in C:\wamp\www\SYSTEM\view.php on line 22
这是我的代码:
start.php
<?php
//First of all, start with some advertisement
header("X-Powered-By:ZOMFG CMS, and ofcourse PHP, but that's less important");
//Then less impotant stuff lololol.
session_start(); //Start a session
mysql_connect($db_host, $db_user, $db_pass); //Connect to database
mysql_select_db($db_name); //Select a database
//Load core
require_once("core.php");
//Load modules
$res_modules = mysql_query("SELECT * FROM ".$_SERVER["db_prefix"]."modules WHERE enabled=1");
echo mysql_error();
$module_exists = array();
while($row_modules = mysql_fetch_array($res_modules))
{
//Load module
$name = $row_modules["name"];
modules::load_module($name);
//and initialize it
eval($name."::init();");
//Yes, it exists
$module_exists[$name] = true;
}
//Check if the user wants shit from a module
if(isset($_GET["m"]))//Yes the user want it
{
//Does the module exist and activated, and has it a function called view?
if(isset($module_exists[$_GET["m"]]) && method_exists($_GET["m"], "view"))//Yep
{
//Load view (should be an array)
eval("\$module_view = ".$_GET["m"]."::view();");
if(!is_array($module_view))//Not an array :(
{
error::e500module($_GET["m"], $_SERVER["REQUEST_URI"]);
}
else//The error would kill the entire script, m'kay
{
view::index();
}
}
else//Nope, so display error
{
error::e404($_SERVER['REQUEST_URI']);
}
}
settings.php
<?php
class settings
{
function get($what)
{
$result_get = mysql_query("SELECT value FROM ".$_SERVER["db_prefix"]."settings WHERE key='$what'");
if(mysql_num_rows($result_get) > 0)
{
$row_get = mysql_fetch_array($result_get);
return $result_get["value"];
}
else
{
return -1;
}
}
}
core.php
<?php
//Load core classes
require_once("settings.php");
require_once("error.php");
require_once("theme.php");
require_once("view.php");
require_once("modules.php");
view.php
<?php
class view
{
function head()
{
include("../THEMES/".settings::get("theme")."/head.php");
}
function foot()
{
include("../THEMES/".settings::get("theme")."/foot.php");
}
function left()
{
include("../THEMES/".settings::get("theme")."/left.php");
}
function right()
{
include("../THEMES/".settings::get("theme")."/right.php");
}
function index()
{
include("../THEMES/".settings::get("theme")."/index.php");
}
}
Start.php 显然是先执行的。除了包含数据库信息的 customsettings.php 之外,不会执行其他页面。如果我在上面的代码中使用了 $_SERVER["db_prefix"],那是因为我需要一个在 customsettings.php 中设置的超全局:
customsettings.php
<?php
$db_host = "localhost"; //Database host
$db_user = "root"; //Database user
$db_pass = "you may not know this"; //Database password
$db_name = "zomfg"; //Database name
$_SERVER["db_prefix"] = "zomfg_";//Prefix, needs to be superglobal
有人可以帮我吗?似乎在包含 settings.php 之前调用了 view.php 的索引函数。抱歉,如果这个问题很大,我只想说清楚。也不要说 eval() 是邪恶的,我知道。
所以我想知道为什么找不到设置类。如果您需要更多源代码,请对此问题发表评论。

虽然很愚蠢,但我也遇到了命名问题。忘记了.php。
