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

Question

我已尝试在

中插入 PaginationRecallComponent (http://bakery.cakephp.org/articles/Zaphod/2012/03/27/paginationrecall_for_cakephp_2_x)

App -> 控制器 -> 组件 -> PaginationRecallComponent.php

用户控制器： 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 PaginationRecallComponent 类中的 initialize 方法的签名与其父类中的签名不同。

如果您查看代码，您会看到Cake/Controller/Component.php 中的签名是：

public function initialize(Controller $controller)

而在PaginationRecallComponent 中是：

function initialize(&$controller)

在第一种情况下，$controller 参数必须是Controller 的一个实例，而在第二种情况下则没有这样的约束。要消除错误，您只需将此约束添加到 PaginationRecallComponent 的 initialize 方法的签名中。
