向客户添加PDF - laravel 5.7

Question

我有一个小型CRM系统.我可以创建,更新和删除客户.我还为每位客户提供了详细的视图.现在我想在单个视图的最后一个按钮:Create Offer.

我有2张桌子.1表有名称:customer with some fields Name,Surname等我创建了这样的客户:

<form method="post" action="/mvs/mvs/public/admin/kunden">
    {{ csrf_field() }}
    <div class="container">
        <div class="row">
            <div class="col-md-12 col-md-offset-2" >

                <div class="form-group">
                    <label for="vorname">Vorname</label>
                    <input type="text" class="form-control" name="vorname" id="vorname" placeholder="Vorname" value="{{ old('vorname') }}" required>
                </div>
                <div class="form-group">
                    <label for="nachname">Nachname</label>
                    <input type="text" class="form-control" name="nachname" id="nachname" placeholder="Nachname" value="{{ old('nachname') }}" required>
                </div>

                <div class="form-group">
                    <label for="strasse">Straße</label>
                    <input type="text" class="form-control" name="strasse" id="strasse" placeholder="Strasse" value="{{ old('strasse') }}" required>
                </div>

                <div class="form-group">
                    <label for="plz">PLZ</label>
                    <input type="number" class="form-control" name="plz" id="plz" placeholder="Plz" value="{{ old('plz') }}" required>
                </div>

                <div class="form-group">
                    <label for="wohnort">Wohnort</label>
                    <input type="text" class="form-control" name="wohnort" id="wohnort" placeholder="Wohnort" value="{{ old('wohnort') }}" required>
                </div>

                 <div class="form-group">
                    <label for="mail">Mail</label>
                    <input type="mail" class="form-control" name="mail" id="mail" placeholder="E-mail" value="{{ old('mail') }}" required>
                </div>

                <div class="form-group">
                    <label for="telefon">Telefon</label>
                    <input type="text" class="form-control" name="telefon" id="telefon" placeholder="Telefon" value="{{ old('telefon') }}" required>
                </div>

                <div class="form-group">
                    <label for="geburtsdatum">Geburtsdatum</label>
                    <input type="date" class="form-control" name="geburtsdatum" id="geburtsdatum" placeholder="Geburtsdatum" value="{{ old('geburtsdatum') }}" required>
                </div>

                <br>

                <button type="submit" class="btn btn-primary">Kunden anlegen</button>
                <a href="{{ URL::previous() }}"><button type="submit" class="btn btn-danger">Abbrechen</button></a>

            </div>
        </div>
    </div>
</form>

详细视图与该页面类似.在详细视图中,我做了一个按钮.该按钮链接到动态PDF控制器.动态PDF控制器工作但我不知道如何从详细视图客户获取数据.我只从表中的所有客户那里获得数据.

这是片段:

function get_customer_data()
{
 $customer_data = DB::table('kundens')
     ->limit(10)
     ->get();
 return $customer_data;
}

我明白这是错误的(我初学者很抱歉)但我不知道如何编码,我从客户那里得到了我在详细视图中所记录的数据.

当我点击按钮时,我希望PDF保存在数据库中并链接到该客户.

我希望我解释清楚.什么时候不请不要低估 - 当它不够时,我试着更好地解释.

如果我理解正确的话：\n您只想在单击按钮时从一位特定客户处获取数据？

\n\n

带有 kunden id 的按钮链接：

\n\n

<a href="/mvs/mvs/public/admin/kunden/pdf/{{ $kunden->id }}">Button html</a>\n

\n\n

新路线：

\n\n

Route::get(\'/mvs/mvs/public/admin/kunden/pdf/{id}\', ControllerName@get_customer_data\');\n

\n\n

控制器更新：

\n\n

function get_customer_data($id)\n{\n //Handle PDF stuff here \n\n $customer_data = DB::table(\'kundens\')\n     ->where(\'id\', \'=\', $id)\n     ->firstOrFail();\n\n//Save PDF link to customer here\n\n $customer_data->save();\n return $customer_data;\n}\n

路线：

\n\n

Route::get(\'/mvs/mvs/public/admin/kunden/pdf/{id}\', DynamicPDFController@index\');\n

\n\n

控制器：

\n\n

namespace MVS\\Http\\Controllers;\n\nuse Illuminate\\Http\\Request;\nuse DB;\nuse PDF;\nuse MVS\\Kunden;\n\nclass DynamicPDFController extends Controller\n{\n    function index(Request $request)\n    {\n\n     $data = $request->all();\n\n     $id = $data[\'kunden-id\'];\n     $customer_data = $this->get_customer_data($id);\n     //$finance_data = $this->get_finance_data();\n     return view(\'dynamic_pdf\')->with(\'customer_data\', $customer_data);\n    }\n\n    function get_customer_data($id)\n    {\n     $customer_data = Kunden::whereId($id)->first();\n     return $customer_data;\n    }\n\n    function pdf()\n    {\n     $pdf = \\App::make(\'dompdf.wrapper\');\n     $pdf->loadHTML($this->convert_customer_data_to_html());\n     return $pdf->stream();\n    }\n\n    function convert_customer_data_to_html()\n    {\n     $customer_data = $this->get_customer_data();\n     $output = \'\n     <h3 align="center">Angebot</h3>\n     <table width="100%" style="border-collapse: collapse; border: 0px;">\n      <tr>\n    <th style="border: 1px solid; padding:12px;" width="20%">Vorname</th>\n    <th style="border: 1px solid; padding:12px;" width="30%">Nachname</th>\n    <th style="border: 1px solid; padding:12px;" width="15%">Stadt</th>\n    <th style="border: 1px solid; padding:12px;" width="15%">PLZ</th>\n   </tr>\n     \';  \n     foreach($customer_data as $kunden)\n     {\n      $output .= \'\n      <tr>\n       <td style="border: 1px solid; padding:12px;">\'.$kunden->vorname.\'</td>\n       <td style="border: 1px solid; padding:12px;">\'.$kunden->nachname.\'</td>\n       <td style="border: 1px solid; padding:12px;">\'.$kunden->wohnort.\'</td>\n       <td style="border: 1px solid; padding:12px;">\'.$kunden->plz.\'</td>\n      </tr>\n      \';\n     }\n     $output .= \'</table>\';\n     return $output;\n    }\n}\n
