Question

我使用的是Larvel 4.2和thujohn / pdf-l4插件。

将HTML页面转换为PDF时遇到问题。当我转换HTML页面时，页面上的所有内容都会显示，除了上面的Morris图表。

我的路线

Route::post('performanceDetail/preview',[
    'as' => 'print.preview',
    'uses' => 'PerformanceController@postPerformanceDetails']);

控制器

public function postPerformanceDetails()
{
    $data = [
        'event' => Input::get('events'),
        'start_date' => Input::get('start_date'),
        'to_date' => Input::get('to_date'),
    ];
        $start_date = date('Y-m-d H:i:s',strtotime($data['start_date'].'00:00:00'));
        $to_date = date('Y-m-d H:i:s',strtotime($data['to_date'].'23:59:59'));
        $stats = Performance::where('event_type','=',$data['event'])
        ->where('campaign_id',Session::get('campaignid'))
        ->where('created_at', '>=',$start_date)
        ->where('created_at','<=',$to_date)
        ->groupBy('perf_date')
        ->orderBy('perf_date', 'DESC')
        ->remember(60)
        ->get([
        DB::raw('Date(created_at) as perf_date'),
        DB::raw('COUNT(id) as perf_count')
        ])
        ->toJSON();
        //return $stats;
        $campaign = Campaign::find(Session::get('campaignid'));
        $list = CategoryList::find($campaign->categorylist_id);
        $totalPerformance = TotalPerformance::find(Session::get('totalPerformance'));
        //$this->layout->title = "Performance details";
        return PDF::load(View::make('performance.show')
        ->with('stats',$stats)
        ->with('campaign',$campaign)
        ->with('list',$list)
        ->with('start_date',$data['start_date'])
        ->with('to_date',$data['to_date'])
        ->with('totalPerformance',$totalPerformance))->show();
}

我试图在没有转换的情况下显示此视图，但它是成功的。但是，执行上述代码时，Morris图表不会显示在PDF上。

我该如何解决这个问题指南。

Answer 1

只需使用{!! !!}而不是在视图文件中使用{{}} ...

还要确保您的文件应该是这样的＆＃39; demo.blade.php＆＃39; ..
