我有一个模板类,它既可以解析 TPL 文件中的数组变量,也可以简单地显示纯 HTML 文件。解析函数工作正常,但显示函数返回以下错误:
“ fatal error :在第 7 行 C:\xampp\htdocs\clancms\controllers\home.php 中的非对象上调用成员函数 display()”
这是 home.php
class Home extends Controller {
function index(){
echo $this->template->display('index_body.tpl');
}
}
这是模板类
class Template {
var $file = '';
var $vars = '';
var $themeID = '';
var $themeTitle = '';
var $themeDescription = '';
var $themePath = '';
function getTheme(){
if($_SESSION['memberid'] != NULL){
$query = "
SELECT memberid, themeid
FROM members
WHERE memberID = '".$_SESSION['memberID']."
LIMIT 1";
if($query = mysql_query($query)){
$member = mysql_fetch_assoc($query);
$query = "
SELECT themeID, themeTitle, themeDescription, themePath
FROM {DB_PREF}
WHERE themeID = ".$member['themeID']."
LIMIT 1";
if($query = mysql_query($query)){
$theme = mysql_fetch_assoc($query);
$this->themeID = $theme['themeID'];
$this->themePath = BASE_PATH.'/templates/'.$theme['themePath'];
$this->themeTitle = $theme['themeTitle'];
$this->themeDescription = nl2br(htmlspecialchars($theme['themeDescription']));
} else {
$this->themePath = BASE_PATH.'/templates/default';
}
} else {
$this->themePath = BASE_PATH.'/templates/default';
}
} else {
$this->themePath = BASE_PATH.'/templates/default';
}
}
function parse($file, $vars){
$this->getTheme();
if(file_exists($this->themePath.'/'.$file)){
$file = file_get_contents($this->themePath.'/'.$file);
foreach($vars as $key => $val){
$file = str_replace('{'.$key.'}', $val, $file);
}
echo $file;
} else {
die('Template parser error: the file \''.$this->themePath.'/'.$file.'\' does not exist!');
}
}
function display($file){
if(file_exists($this->themePath.'/'.$file)){
$file = file_get_contents($this->themePath.'/'.$file);
echo $file;
} else {
die('Template parser error: the file \''.$this->themePath.'/'.$file.'\' does not exist!');
}
}
}
更新
对不起,我忘了包括那个
<?php
class Controller {
function Controller(){
$this->initialize();
}
function initialize(){
$classes = array(
'load' => 'Load',
'uri' => 'URI',
'config' => 'Config',
'template' => 'Template'
);
foreach($classes as $var => $class){
if(file_exists($this->app_path.'/classes/'.$class.'.php')){
require_once(BASE_PATH.'/classes/'.$class.'.php');
$this->$var =& new $class;
} else {
return FALSE;
}
}
}
}
?>
最佳答案
您的 Home 实例上的成员变量 $template 没有被初始化。某处需要调用 $this->template = new Template();
或类似的东西。
这可能应该在 Home __construct 或父 Controller 类中。
根据您的 Controller 初始化函数,我假设给定类之一的文件不存在,因此它会通过 return false;
回显正在加载的类,如果它到达数组末尾我会感到惊讶。
