我尝试为自定义模块添加自定义挂钩。
如果我将它直接添加到 initContent()内部的FrontController.php (/ classes / controller / FrontController.php),并在 displayHeader()< / strong>函数新定义变为:
$this->context->smarty->assign(array(
'HOOK_HEADER' => $hook_header,
'HOOK_TOP' => Hook::exec('displayTop'),
'HOOK_MYCUSTOM' => Module::hookExec('myCustomHook'), /* <- my hook */
'HOOK_LEFT_COLUMN' => ($this->display_column_left ? Hook::exec('displayLeftColumn') : ''),
'HOOK_RIGHT_COLUMN' => ($this->display_column_right ? Hook::exec('displayRightColumn', array('cart' => $this->context->cart)) : ''),
'HOOK_FOOTER' => Hook::exec('displayFooter')
));
完美无缺......
但是如果我尝试通过添加包含以下内容的 /modules/myModule/override/classes/controller/FrontController.php 文件来覆盖FrontControlle.php:
class FrontController extends FrontControllerCore
{
public function initContent()
{
$this->process();
if (!isset($this->context->cart))
$this->context->cart = new Cart();
if ($this->context->getMobileDevice() == false) {
if (!isset($this->context->cart))
$this->context->cart = new Cart();
$this->context->smarty->assign(array(
'HOOK_HEADER' => Hook::exec('displayHeader'),
'HOOK_TOP' => Hook::exec('displayTop'),
'HOOK_LEFT_COLUMN' => ($this->display_column_left ? Hook::exec('displayLeftColumn') : ''),
'HOOK_RIGHT_COLUMN' => ($this->display_column_right ? Hook::exec('displayRightColumn', array('cart' => $this->context->cart)) : ''),
'HOOK_MYCUSTOM' => Module::hookExec('myCustomHook') /* <- my hook */
));
} else {
$this->context->smarty->assign(array(
'HOOK_MOBILE_HEADER' => Hook::exec('displayMobileHeader'),
));
}
}
public function displayHeader($display = true){
if (!self::$initialized)
parent::init();
self::$smarty->assign(array(
'HOOK_MYCUSTOM' => Module::hookExec('myCustomHook') /* <- my hook */
));
return parent::displayHeader();
}
}
我得到以下内容:
注意:未定义的索引:HOOK_MYCUSTOM in /home6/viralcom/public_html/osgaming/tools/smarty/sysplugins/smarty_internal_templatebase.php(157) :第54行的eval()&#39代码
注意:尝试获取非对象的属性 /home6/viralcom/public_html/osgaming/tools/smarty/sysplugins/smarty_internal_templatebase.php(157) :第54行的eval()&#39代码
请您帮我弄清楚上面的代码有什么问题?
我已更改为文件 /modules/myModule/override/classes/controller/FrontController.php
行:
'HOOK_MYCUSTOM' => Module::hookExec('myCustomHook')
with:
'HOOK_MYCUSTOM' => Hook::exec('myCustomHook')
此后我添加了一个自动删除文件的功能:
/cache/class_index.php
进入我模块的安装功能:
public function install() {
if (!parent::install() OR !$this->installDB() OR !$this->delecache())
return false;
[...]
}
public function delecache(){
if(!unlink($_SERVER['DOCUMENT_ROOT']."/cache/class_index.php"))
return false;
return true;
}
现在工作正常!谢谢大家!
答案 0 :(得分:0)
您是否删除了位于/ cache /文件夹中的 class_index.php 文件?
每次覆盖一个类时,都必须删除该文件。
