Adjust number of Rows to Form:: Textarea Laravel 5
提问by Jonny C
How can I control the number of Rows added to a textarea using the Illuminate\Html\FormFacadeclass?
如何使用Illuminate\Html\FormFacade该类控制添加到 textarea 的行数？
I have added the field into my template.
我已将该字段添加到我的模板中。
<div class="form-group">
{!! Form::label('placeOfDeath','Place of Death') !!}
{!! Form::textarea('placeOfDeath',null,['class'=>'form-control']) !!}
</div>
When it gets rendered the textarea has cols="50"and rows="10"
当它被渲染时，textarea 有cols="50"和rows="10"
<textarea class="form-control" name="placeOfDeath" cols="50" rows="10" id="placeOfDeath"></textarea>
I want a way to control these numbers, I have checked the documentation but couldnt spot anything?
我想要一种控制这些数字的方法，我已经检查了文档但找不到任何东西？

The options (third parameter) array is actually the attributes array of that element, you so can just pass any 'key' => 'value'and the element will have it as attributes, for example:
选项（第三个参数）数组实际上是该元素的属性数组，因此您可以只传递 any'key' => 'value'元素并将其作为属性，例如：
{!! Form::textarea('placeOfDeath',null,['class'=>'form-control', 'rows' => 2, 'cols' => 40]) !!}

I have accepted the other answer as it works perfectly.
我已经接受了另一个答案，因为它完美无缺。
I have also found that the class actually checks for an attribute size
我还发现该类实际上检查了一个属性 size
protected function setQuickTextAreaSize($options)
{
$segments = explode('x', $options['size']);
return array_merge($options, array('cols' => $segments[0], 'rows' => $segments[1]));
}
Its a minor space saving, Im not sure it makes the code anymore readable, but it is an alternative to cut off a few characters
它节省了一点空间，我不确定它是否使代码更具可读性，但它是截断几个字符的替代方法
['size' => '30x5']

Also try this:
也试试这个：
{!! Form::textarea('placeOfDeath',null, array('class'=>'form-control',
'rows' => 10, 'cols' => 50)) !!}
