在将插件安装到我的本地Wordpress站点之后，qfpregister小部件没有在我的可用小部件页面中列出。还需要哪些其他步骤来确保小部件可用？
最合适的回答,由SO网友:Tim Malone 整理而成
这不起作用的原因有很多。最好的出发点是Widgets API page in the Codex. 它概述了创建小部件的基本类。至少，您需要一个具有__construct(), widget(), form(), 和update() 作用
您还需要正确注册小部件。这个register_widget() function 将小部件的类作为其参数，而此时您正在通过函数名发送。
您的widget注册也永远不会被调用，因为您的钩子只添加到它调用的函数中：这意味着它永远不能被添加，因为它从未被调用过。
将小部件注册移到类外，并按如下方式进行设置：
function register_qfpform(){
register_widget(\'qfpregister\');
}
add_action(\'widgets_init\', \'register_qfpform\');
您可以在
Codex\' Plugin API page.
之后，您需要查看registration_form() 函数，并可能将大部分代码移动到widget() 作用这个widget() 函数输出小部件的前端代码，而form() 函数输出后端代码。您当前的registration_form() 功能也很差-有一个return; 最后，在更新代码之前，这意味着更新代码永远不会运行。
还有一点不清楚您试图做什么：函数返回变量的内容$html, 但也有一些echo 在此之前的语句将直接呼应该人的名字和姓氏，而不在表单的其余流程中。
我会告诉你Widgets API page in the Codex. 以这里的例子为基础，并以此为基础。您现在拥有的是一堆无法工作的代码。
