在Laravel 5中，textarea字段的验证总是失败

Question

我有一个表单的自定义验证器，其中验证规则是从数据库表中提取的。验证器工作正常，直到我在textarea上使用它。规则很简单，需要＆＃39;，但即使有数据发送，验证也总是失败。

$rules = $this->getFormRules($slug);
$validator = Validator::make(Input::all(), $rules);
if ($validator->fails()) {
    return Redirect::to($request->uri)
        ->withErrors($validator);
} else { ... }

private function getFormRules($slug = null) {
    $elements = Element::all();
    foreach($elements as $element) {
        if(isset($element->mandatory) == 1) {
            $rules_array[$element->field_name] = 'required';
        }
    }
    return $rules_array;
}

rules数组如下：

Array (
    [Name] => required
    [E-mail] => required
    [Company] => required
    [Phone] => required
    [Message] => required 
)

Message是textarea并且在那里继续失败

<form method="POST" action="/form-send" enctype="multipart/form-data">
    <input type="hidden"name="_token"value="8ZtkSm7QkloWxAH5x3KkAzW2BS1UEpLv4SkuJ1Nu">
    <input type="hidden" name="uri" value="/contact">
    <div>
        <label>Name<span>*</span></label>
        <input type="text" name="Name" value="">
    </div>
    <div>
        <label>E-mail<span>*</span></label>
        <input type="text" name="E-mail" value="">
    </div>
    <div>
        <label>Company</label>
        <input type="text" name="Company" value="">
    </div>
    <div>
        <label>Phone</label>
        <input type="text" name="Phone" value="">
    </div>
    <div>
        <label>Message<span>*</span></label>
        <textarea name="Message"></textarea>
    </div>
    <div>
        <button type="submit" name="Send">Send</button>
    </div>
</form>
