当我尝试从使用“UploadPack”的 Controller 加载 View 时，出现以下错误 - (来源:- https://github.com/szajbus/uploadpack):-
严格(2048):UploadBehavior::setup() 的声明应与 ModelBehavior::setup(Model $model, $config = Array) [APP\Plugin\upload_pack\Model\Behavior\UploadBehavior.php, line 兼容15]
我的“UploadBehavior.php”和“ModelBehavior.php”文件如下，有人知道如何解决此错误吗？

/**
* Model behavior base class.
*
* Defines the Behavior interface, and contains common model interaction functionality. Behaviors
* allow you to simulate mixins, and create reusable blocks of application logic, that can be reused across
* several models. Behaviors also provide a way to hook into model callbacks and augment their behavior.
*
* ### Mixin methods
*
* Behaviors can provide mixin like features by declaring public methods. These methods should expect
* the model instance to be shifted onto the parameter list.
*
* {{{
* function doSomething(Model $model, $arg1, $arg2) {
* //do something
* }
* }}}
*
* Would be called like `$this->Model->doSomething($arg1, $arg2);`.
*
* ### Mapped methods
*
* Behaviors can also define mapped methods. Mapped methods use pattern matching for method invocation. This
* allows you to create methods similar to Model::findAllByXXX methods on your behaviors. Mapped methods need to
* be declared in your behaviors `$mapMethods` array. The method signature for a mapped method is slightly different
* than a normal behavior mixin method.
*
* {{{
* public $mapMethods = array('/do(\w+)/' => 'doSomething');
*
* function doSomething(Model $model, $method, $arg1, $arg2) {
* //do something
* }
* }}}
*
* The above will map every doXXX() method call to the behavior. As you can see, the model is
* still the first parameter, but the called method name will be the 2nd parameter. This allows
* you to munge the method name for additional information, much like Model::findAllByXX.
*
* @package Cake.Model
* @see Model::$actsAs

最佳答案
UploadBehavior的setup()方法的签名应该与UploadBehavior中的setup()方法的签名相同父类。这意味着您必须将 UploadBehavior 中的 public function setup(&$model, $settings = array()) 更改为 public function setup(Model $model , $settings = array()) 并且错误应该消失。
关于php - Cakephp查看错误-使用UploadPack存储图片，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/13103813/
