Question

控制器未从FORM获取数据。我意识到Form默认使用Post方法，而Route使用Get，但如果我改变了，那么表单将不会显示表单字段。验证失败，因为“required”没有获得任何值，因此它返回到同一页面。如果我删除了验证过滤器，那么它会转到结果页面，但它所做的只是显示表的所有内容，因为它从表单中没有获取参数（where）。奇怪的是，在过去，它工作，但我必须搞砸了部分代码，现在却没有。为了节省空间，我遗漏了许多在问题中没有发挥作用的领域。

该表格有三个相互依存的字段国家，地区和城镇，这些字段填写正常。

FORM：

<form action = "{{URL::route('sacapropiedades')}} "class="form-horizontal" id="my_form" name="my_form">

        <div class="form-group">            
        <div class="col-sm-3">      
        <label for="country">Pays</label>
        <select name ="country" {{ (Input::old('country')) ?' value ="' . e(Input::old('country')). '"' : ''  }} id = "country" class="form-control">                 
        @foreach($countries as $country)
        <option value="{{$country->country}}">{{$country->country}}</option>  
            @endforeach
        </select>
        </div>

        <div class="col-sm-3">
        <label for="town">Ville</label>
        <select name ="town" {{ (Input::old('town')) ?' value ="' . e(Input::old('town')). '"' : ''  }}id = "town" class="form-control">                 
        </select>
        </div>      

        </div><!-- END OF THIRD FORMGROUP -->
        <div class="form-group">
            <div class="col-sm-4">          
        </div>
        <div class="col-sm-2">

post方法是必需的，否则Laravel不会使用正确的数据将其重定向到正确的方法。它之前是如何运作的？幸运的是，可能。：）

Route::get('realestate/listproperty', array(

    'as' =>'sacapropiedades',            
    'uses' =>'countriesregionstownsController@findproperty'       

));

Route::post('realestate/listproperty', array(

    'as' =>'sacapropiedades',            
    'uses' =>'countriesregionstownsController@findproperty'       

));

或

Route::match(array('GET', 'POST'), 'realestate/listproperty', array(

    'as' =>'sacapropiedades',            
    'uses' =>'countriesregionstownsController@findproperty'       

));

或

Route::any('realestate/listproperty', array(

    'as' =>'sacapropiedades',            
    'uses' =>'countriesregionstownsController@findproperty'       

));

然后你可能不需要在GET上验证：

if (Request::getMethod() == 'POST')
{
    $validator = Validator::...
}

编辑：

抱歉，我忽略了这个问题：

不要手动编写FORM标签，而是使用Laravel的FormBuilder类：

<?php Form::open(array('route' => 'sacapropiedades', 'class' => 'form-horizontal', 'id' => 'my_form', 'name' => 'my_form')); ?>

不同之处在于它会为您添加方法，并且还会在表单中添加csrf标记。

Laravel。控制器没有从表单获取值
