将输入值从一个页面发送到另一个页面

Question

I'm working on Laravel project and I want to send my input values from the FORM from one page (the inscription page) to a pdf page (which I want the user to be able to download). I couldn't find a way to send them from that page to the other

input:all using the $request in the controller

<div class="fieldgroup">
                            <input type="text" style="color:0B0C51" onclick="submitform2()" name="cin" id="cin"
                                    placeholder="N°CIN" maxlength="8" class="required"></i><br>

                    </div>


                    <div class="fieldgroup">
                            <input type="text" style="color:0B0C51" v-model="prenom" name="prenom" id="prenom"
                                    placeholder="Prenom" class="required"><br>
                    </div>


                    <div class="fieldgroup">
                            <input type="text" style="color:0B0C51" v-model="nom" onclick="submitform2()" name="nom"
                                    id="nom" placeholder="Nom" class="required"><br>
                    </div>

                    <div class="fieldgroup">
                            <input type="mail" style="color:0B0C51" name="email" id="email" placeholder="Email"
                                    class="required" />

                    </div>

ViewController :

    class ViewController extends Controller
{

public function generatePDF(Request $request){
    $request=this.
    $data="form";
    $pdf= PDF::loadView('pdf',compact('data'));
    return $pdf->download('Terms.pdf');
}

}

web.php:

       Route::get('/pdf','ViewController@generatePDF');

inscriController:

public function store(Request $request)
{   
    $cin = $request->input('cin');
    $data = array(['cin'=>$cin ]);

    DB::table('form')->insert($data);

    return redirect('/pdf')->withInput();

This returns an empty form page without the input values

Answer 1

It may be easier to load the pdf right in the store method of inscriController. As it is, you are redirecting and passing no data into the pdf generator / view. You set $request as the controller ($this), which has none of the form data, and then you pass a single word 'form' as your data-set into the PDF generator. I don't think this will work the way you wish - I assume the pdf view is looking for specific variables (not 'form'), and thus it is failing because those vars are missing. IE you'd want to pull those vars like $name = $request->get('name') and pass whatever pdf.blade.php view needs from your $request var.

If you don't want to do it all in the store function, perhaps pass it to a method in the same inscriController? This way you can easily push the actual request object into that method and pull the fields you need for the PDF view.
