Retrieving GET and POST data inside controller in Laravel 4
提问by Jan
I've been searching the web for how to get POST data inside the controller, so far I have found two solutions: Input::get()and $_POST.
我一直在网上搜索如何在控制器中获取 POST 数据，到目前为止我找到了两个解决方案：Input::get()和$_POST.
The comment for Input::get()reads:
评论Input::get()如下：
/**
* Gets a "parameter" value. * * This method is mainly useful for libraries that want to provide some flexibility. * * Order of precedence: GET, PATH, POST * * Avoid using this method in controllers: * * * slow * * prefer to get from a "named" source * * It is better to explicitly get request parameters from the appropriate * public property instead (query, attributes, request). * * @param string $key the key * @param mixed $default the default value * @param Boolean $deep is parameter deep in multidimensional array * * @return mixed */
/**

What is this "named" source they refer to? What is it I should use instead of Input::get()?
他们所指的这个“命名”来源是什么？我应该用什么来代替Input::get()？

The documentationshows you can retrieve an input value for any HTTP verb by using Input::get().
该文档显示您可以使用 检索任何 HTTP 动词的输入值 Input::get()。
$name = Input::get('name');

TO get all the inputs use Input::all()method.
To check if specific column exists use Input::has('column_name')eg.Input::has('name').
To retrieve column value use Input::get('column_name')eg. Input::get('name').
获取所有输入使用Input::all()方法。要检查特定列是否存在，请使用Input::has('column_name')例如。Input::has('name'). 要检索列值使用Input::get('column_name')例如。Input::get('name').
