The called constructor method for WP_Widget is deprecated since version 4.3.0
提问by aniruddh
I just updated to WordPress 4.3 and it seems that something is broken.
我刚刚更新到 WordPress 4.3，似乎有些东西坏了。
I get this error that shows up on my page:
我收到显示在我的页面上的错误：
Notice: The called constructor method for WP_Widget is deprecated since version 4.3.0! Use
__construct()instead. in /mnt/stor13-wc1-ord1/754452/www.eden-festival.com/web/content/securewp/wp-includes/functions.php on line 3457
注意：WP_Widget 被调用的构造函数方法从 4.3.0 版本开始被弃用！使用
__construct()来代替。在 /mnt/stor13-wc1-ord1/754452/www.eden-festival.com/web/content/securewp/wp-includes/functions.php 第 3457 行
Is there something that needs to be fixed?
有什么需要修复的吗？

Since php 7 isn't supported anymore, the old php 4 object construct was replaced with __construct(). Wordpress developers created a notice message so the plugin developers would change the way their plugins work (and also so it could run on next php versions). Since php 4 has long been dead, there's no reason to use this style of object construct.
由于不再支持 php 7，旧的 php 4 对象构造被替换为__construct(). Wordpress 开发人员创建了一条通知消息，以便插件开发人员更改其插件的工作方式（并且还可以在下一个 php 版本上运行）。由于 php 4 早已死了，没有理由使用这种风格的对象构造。
How to fix?
怎么修？
Option 1 - not going to upgrade to newer php versions
选项 1 - 不打算升级到较新的 php 版本
just add
add_filter('deprecated_constructor_trigger_error', '__return_false');
只需添加
add_filter('deprecated_constructor_trigger_error', '__return_false');
to your functions.php file it will ignore those notices.
到您的functions.php 文件，它会忽略这些通知。
Option 2 - might upgrade to php 7 / prefer dealing with the issue rather than silencing it
选项 2 - 可能会升级到 php 7 / 更喜欢处理问题而不是使其沉默
If this is a third party plugin, beware that if you make the change yourself and the plugin developer releases an update then it will override your changes. Contacting the plugin developer to fix this issue will be the best option
如果这是第三方插件，请注意，如果您自己进行更改并且插件开发人员发布更新，那么它将覆盖您的更改。联系插件开发者解决这个问题将是最好的选择

I am also getting the same error And I fixed it in such a way
我也遇到了同样的错误 我以这种方式修复了它
class Dokan_Category_Widget extends WP_Widget {
/**
* Constructor
*
* @return void
**/
public function __construct() {
$widget_ops = array( 'classname' => 'dokan-category-menu', 'description' => __( 'Dokan product category menu', 'dokan' ) );
$this->WP_Widget( 'dokan-category-menu', 'Dokan: Product Category', $widget_ops );
}
}
As way of calling constructor in such way is deprecated in php 7, so I replaced calling way as $this->WP_Widget()with parent::__construct()
由于调用这样的方式构造方法在PHP 7弃用，因此，我调用替换方式$this->WP_Widget()与parent::__construct()
class Dokan_Category_Widget extends WP_Widget {
/**
* Constructor
*
* @return void
**/
public function __construct() {
$widget_ops = array( 'classname' => 'dokan-category-menu', 'description' => __( 'Dokan product category menu', 'dokan' ) );
//$this->WP_Widget( 'dokan-category-menu', 'Dokan: Product Category', $widget_ops );
parent::__construct('dokan-category-menu', 'Dokan: Product Category', $widget_ops );
}
}

I guess you are using some plugin that is not updated after wordpress updates and having some code like class ***_Widget extends WP_Widget {.you should update that plugin or deactivate it until It is updated.
我猜你正在使用一些在 wordpress 更新后没有更新的插件，并且有一些像class ***_Widget extends WP_Widget {.you 应该更新该插件或停用它的代码，直到它更新。

Declaring a function then calling the parent constructor resolved this issue for me.
声明一个函数然后调用父构造函数为我解决了这个问题。
class myClass extends WP_Widget {
function __construct(){
parent::__construct(...) // calls constructor from WP_Widget class
}
}

Its kind of warning you can hide the error using add a line in your wp-config.phpfile in your site root directory
它的警告类型，您可以使用wp-config.php在站点根目录中的文件中添加一行来隐藏错误
define('WP_DEBUG', false);
定义（'WP_DEBUG'，假）；

I experienced this issue and I found by changing the 'true' statement to 'false' in /wp-includes/functions.php it disabled the errors.
我遇到了这个问题，我发现通过将 /wp-includes/functions.php 中的“true”语句更改为“false”，它禁用了错误。
if ( WP_DEBUG && apply_filters( 'deprecated_constructor_trigger_error', true ) ) {
if ( WP_DEBUG && apply_filters( 'deprecated_constructor_trigger_error', true ) ) {
