Wie aktualisiert man eine Datenbanktabelle in Laravel 5.2

Question

Ich habe ein Projekt in Laravel 5.2 erstellt. In dieser "myform.blade.php" Seite, erstellt Formular für die Registrierung des Benutzers. Nach der Registrierung wird der aktuelle Benutzer im Tabellenformat angezeigt ("index.blade.php"). Dort habe ich zwei dynamische Buttons wie den Drop innerhalb des Tisches gegeben. Eine für Bearbeiten und andere für Bearbeiten/Anzeigen. Wenn ich auf Löschen klicke, wird die entsprechende Zeile aus der Datenbank gelöscht, indem der Primärschlüssel (employeeID) als Referenz-ID verwendet wird. Wenn ich auf die Schaltfläche Bearbeiten/Ansicht klicke, wird auf "edit.blade.php" umgeleitet. Dort habe ich das gleiche Formular wie in myform.blade.php erstellt. Wenn wir die Details bearbeiten wollen, können wir von dort aus bearbeiten. Ich kann die Daten von der Datenbank zu dem Formular, das ich in der "edit.blade.php" erstellt habe, abrufen. Aber ich weiß nicht, wie man die Daten von ihren aktualisiert, ohne die gleichen Daten wieder einzusetzen (es ist nicht möglich, weil es Integritätseinschränkungsverletzung verursacht, indem man versucht, doppelten Primärschlüssel einzuführen. Kann irgendjemand mir bitte erklären, wie man Aktualisierung durchführt) spürbar sind. Antworten.

Answer 1

Sie wollen dies in Ihrer Route ändern:

Route::get('myform/update/{id}', 'UserController@update'); 

zu

//Because the data in your form is transferred/submitted by post request 
Route::post('myform/update/{id}', 'UserController@update'); 

dann Update-Funktion auf diese

ändern

// Update user 
public function update(Request $request, $id) 
{ 
    try{ 
     //Find the user object from model if it exists 
     $user= myform::findOrFail($id); 

     //$request contain your post data sent from your edit from 
     //$user is an object which contains the column names of your table 

     //Set user object attributes 
     $user->employeeNo = $request['employeeNo']; 
     $user->Cname = $request['Cname']; 
     $user->dob = $request['dob']; 
     $user->phoneNumber = $request['phoneNumber']; 
     $user->address = $request['address']; 

     // Save/update user. 
     // This will will update your the row in ur db. 
     $user->save(); 

     return view('myform.index')->with('user', $user); 
    } 
    catch(ModelNotFoundException $err){ 
     //Show error page 
    } 
} 

Wenn Sie Fragen haben oder brauchen Klarheit Sie sind herzlich willkommen :)

-Update in Ihrer Bearbeitungsansicht fragen

ändern Sie diese

<form class="form-horizontal" role="form" method="POST" action="{{ url('myform/myform/') }}"> 

zu

<form class="form-horizontal" role="form" method="POST" action="{{ url('myform/update/').$user->employeeID}}"> 

Änderung $user->employeeID zu, was auch immer Ihre Primärschlüssel ist.

Auch dieses

<button type="submit" class="btn btn-warning"><a href="{{ url('myform/update/'.$use->employeeID) }}"> 
             Update</a> 
            </button> 

dieses Sie, wie ich weiter oben in dieser Antwort erwähnt beheben hat

<button type="submit" class="btn btn-warning">Update</button> 

Aso nicht ändern Sie Ihre Route.
