CakePHP PaginationRecallComponent,Strict(2048):PaginationRecallComponent :: initialize()的声明

Question

我试图插入PaginationRecallComponent(http://bakery.cakephp.org/articles/Zaphod/2012/03/27/paginationrecall_for_cakephp_2_x),

App - > Controller - > Component - > PaginationRecallComponent.php

UserController:public $ components = array('PaginationRecall');

为什么我收到以下错误:

Strict (2048): Declaration of PaginationRecallComponent::initialize() should be compatible with Component::initialize(Controller $controller) [APP/Controller/Component/PaginationRecallComponent.php, line 46]

Answer 1

您收到此错误是因为类中initialize方法的签名与PaginationRecallComponent其父类中的签名不同.

如果您查看代码,您将在Cake/Controller/Component.php签名中看到:

public function initialize(Controller $controller)

而在PaginationRecallComponent它是:

function initialize(&$controller)

在第一种情况下,$controller参数必须是实例Controller,而在第二种情况下,没有这样的约束.要摆脱错误,您只需将此约束添加到initialize方法的签名中即可PaginationRecallComponent.
