Laravel视图中的命名参数

Question

底部的解决方案

我想在刀片模板中生成一个链接到我的控制器操作和传递两个参数。但拉勒维尔总是投

preg_replace()：参数不匹配，模式是字符串，替换是数组

routes.php

Route::get('/projects/{project_id}/canals/{canal_id}/damages', array('as' => 'listDamages', 'uses' => 'DamageController@listDamages'));

DamageController.php

public function listDamages($project_id, $canal_id){
        $damages = Canal::find($canal_id)->damages;
        $canal = Canal::find($canal_id);
        $project = Project::find($project_id);
        return View::make('damages.list',array('damages' => $damages, 'canal' => $canal, 'project' => $project));
    }

view.blade.php

/* Values are:
$project->id = 71;
$canal->id = 5103;
*/

{{ Form::open(array('route' => array('listDamages',array('project_id' => $project->id,'canal_id' => $canal->id)), 'method' => 'get', 'class' =>'action-form')) }}
<button type="submit" href="{{ route('listDamages',array('project_id' => $project->id,'canal_id' => $canal->id)) }}" class="small">Auswählen</button>
{{ Form::close() }}

表单中生成的URL应该如下所示：

项目/71/运河/5103/损害赔偿

SOLUTIONEdit工作代码view.blade.php

{{ Form::open(array('route' => array('listDamages', $project->id, $canal->id), 'method' => 'get', 'class' =>'action-form')) }}
<button type="submit" href="{{ route('listDamages',array($project->id, $canal->id)) }}" class="small">Auswählen</button>
{{ Form::close() }}

Answer 1

尝试：

echo Form::open(array('route' => array('listDamages', $project->id, $canal->id)));

不过，还没有测试过上面的内容。无论如何，您始终可以构建url，尽管您失去了命名路由的好处：

echo Form::open(array('url' => 'projects/'.$project->id.'/canals/'.$canal->id.'/damages'));
