How to set form input required attribute in laravel 4
提问by GothamCityRises
I'm using the laravel framework for a project, and I'm implementing a basic form page, where I require certain values to be required, something that can be done very easily in HTML5.
我正在为一个项目使用 laravel 框架，并且我正在实现一个基本的表单页面，其中我需要某些值required，这在 HTML5 中可以很容易地完成。
<input type="text" name="abc" required>
In laravel, without the requiredattribute, the same would be :
在 laravel 中，如果没有该required属性，则为：
{{ Form::text('abc') }}
How do I incorporate a required attribute in the above statement?
如何在上述语句中加入必需的属性？

Since simply writing ['required']did not work, I searched online a bit more and found the answer, so I thought I'd share it here.
由于单纯的写['required']是行不通的，我在网上多搜了一下，找到了答案，所以想在这里分享一下。
The third parameter is an array of optional attributes, which, in convention, must be written as:
第三个参数是一个可选属性数组，按照惯例，必须写成：
{{ Form::text('abc','',array('required' => 'required')) }}
Similarly, for a radio button with default selected/checked we have:
同样，对于默认选中/选中的单选按钮，我们有：
{{ Form::radio('abc', 'yes', array('checked' => 'checked')) }}

Check out the API-Docs. The method signature shows that you can provide 3 parameters.
查看API 文档。方法签名显示您可以提供 3 个参数。
The first one is the nameattribute, the second one is the valueattribute. Third one is your array with any additional attributes.
第一个是名称属性，第二个是值属性。第三个是具有任何其他属性的数组。
So just call your method with:
所以只需调用你的方法：
{{ Form::text('key', 'value', ['required']) }}
And a requiredattribute will be attached to your input field.
并且required属性将附加到您的输入字段。

I believe the correct answer is similar to the other post where the third parameter is
我相信正确的答案类似于第三个参数是的另一篇文章
array('required' => 'required')
however to get the attribute without any value you can do the following:
但是要获取没有任何值的属性，您可以执行以下操作：
array('required' => '')
The input field (for text example), will then look what was necessary in the question.
输入字段（例如文本）将查看问题中的必要内容。
Laravel Example:
Laravel 示例：
{{ Form::text('title', '', array('tabindex' => '1', 'required' => '')) }}
HTML output:
HTML 输出：
<input tabindex="1" required name="title" type="text" value="" id="title">
I believe this actually shorthand for required='', just wanted to add this note
我相信这实际上是 required='' 的简写，只是想添加此注释
