laravel 5.0在數據庫中刪除和編輯

Question

如何使用公共函數銷燬和編輯從Laravel 5.0的數據庫中刪除或編輯數據？

這是我的圖書館，在這裏我想刪除或從我的數據庫更新的東西

@foreach ($allJobs as $job) 
    <tr> 
     <td><img src="{{$job->selected_icon}}" width="50" /> </td> 
     <td>{{$job->jobtitle_de}}</td> 
     <td>{{$job->location}}</td> 
     <td><img src="{{$job->selected_image}}" width="100" /></td> 
     <td>{{$job->workinghours}}</td> 
     <td>{{$job->grey_header_de}}</td> 
     <td>{{$job->date}}</td> 
     <td> 
      <a href=""><button>Edit</button></a>&nbsp;<a href="/delete"> 
      <button>Delete</button></a></td> 
      <!--<td> <button type="delete" name="button"></button>--> 
     <td> 
     </td> 
    </tr> 
@endforeach 

Answer 1

現在我發現這個在互聯網上：

<div class="library"> 
<table> 
@foreach ($allJobs as $job) 
<tr> 
    <td><img src="{{$job->selected_icon}}" width="50" /> </td> 
    <td>{{$job->jobtitle_de}}</td> 
    <td>{{$job->location}}</td> 
    <td><img src="{{$job->selected_image}}" width="100" /></td> 
    <td>{{$job->workinghours}}</td> 
    <td>{{$job->grey_header_de}}</td> 
    <td>{{$job->date}}</td> 
<td> 
    {{ Form::open(['method' => 'DELETE', 'route' => 'job.destroy', $job]- 
    >id]) }} 
     {{ Form::hidden('id', $job-id) }} 
     {{ Form::submit('delete', ['class' => 'library']) }} 
    {{Form::close}} 
    </td> 
</tr> 
@endforeach 

，這是我的控制器

public function destroy($id) 
{ 
    $jobs = Job::findOrFail($id); 
    $jobs->delte(); 

    return redirect::route('/'); 
} 

Answer 2

在你的控制器（我會假設你已經創建了），實現了這兩個功能。

 
public function edit($id) { 
    // Create a var called `$job` and uses the function `find()` passing into the $id that you clicked before 

    $job = Job::find($id); 

    // Return a view with the object that you found into a edit view 
    return view('jobs.edit', [ 
     'job' => $job 
    ]); 
} 

public function destroy($id) { 
    // Use the function `find()` passing into the $id that you clicked before and that use the delete method to delete the job 
    Job::find($id)->delete(); 

    // Returning into a route that contains the jobs, probably 
    return redirect()->route('jobs'); 
}

my Controller: 

<?php namespace App\Http\Controllers; 

use App\Http\Requests; 
use App\Http\Controllers\Controller; 
use Request; 
use App\Jobs; 

class JobController extends Controller { 

/** 
* Display a listing of the resource. 
* 
* @return Response 
*/ 
public function index() 
{ 
    return view('library',['allJobs' => Jobs::all()]); 
} 

//my create function 
public function create() 
{ 
    return view('add'); 
} 
/** 
* Store a newly created resource in storage. 
* 
* @return Response 
*/ 
public function store(Request $request) 
{ 
    $job = new Jobs(); 

    $job->jobtitle_de = array_key_exists('jobtitle_de',$_POST) ? 
$_POST['jobtitle_de'] : ''; 
    $job->jobtitle_en = array_key_exists('jobtitle_en',$_POST) ? 
$_POST['jobt'] : ''; 


    if (array_key_exists('place', $_POST)) { 
     $places = $_POST['place']; 
     $placesString = ""; 
     foreach ($places as $p) { 
      $placesString .= $p.','; 
     } 
     $job->location = $placesString; 
    } 

    $job->workinghours = array_key_exists('workinghours',$_POST) ? 
    $_POST['workinghours'] : ''; 
    $job->workinghours_de = array_key_exists('workinghours',$_POST) ? 
    $_POST['workinghours'] : ''; 
    $job->selected_image= array_key_exists('selected_image',$_POST) ? 
    $_POST['selected_image'] : ''; 
    $job->grey_header_de = array_key_exists('grey_header_de',$_POST) ? 
    $_POST['grey_header_de'] : ''; 



    $job->selected_icon = array_key_exists('selected_icon',$_POST) ? 
    $_POST['selected_icon'] : ''; 
    $job->selected_icon = array_key_exists('selected_icon',$_POST) ? 
    $_POST['selected_icon'] : ''; 
    $job->selected_icon = array_key_exists('selected_icon',$_POST) ? 
    $_POST['selected_icon'] : ''; 
    $job->selected_icon = array_key_exists('selected_icon',$_POST) ? 
    $_POST['selected_icon'] : ''; 



    $job->date; 

    if (array_key_exists('date',$_POST) && !empty($_POST['date'])) { 
     $date = $_POST['date']; 
     $date = explode('/',$_POST['date']); 
     $newdate = $date[2]."-".$date[0]."-".$date[1]; 
     $job->date = $newdate; 
    } 

    $job->grey_header_de = $_POST['grey_header_de']; 

    if (array_key_exists('workinghours',$_POST) && $_POST['workinghours'] 
=== "full-time") { 
     $job->workinghours = $_POST['workinghours']; 
     $job->workinghours_de = "Vollzeit"; 
    } 
    if (array_key_exists('workinghours',$_POST) && $_POST['workinghours'] 
=== "part-time"){ 
     $job->workinghours = $_POST['workinghours']; 
     $job->workinghours_de = "Teilzeit"; 
    } 
    try { 
     $job->save(); 
    } 
    catch (Exceptions $e) { 
     echo $e->getMessage(); 
    } 

    return redirect()->action('JobController@index'); 
} 


//my edit function 
public function edit($id) 
{ 
    $job = Job::find($id); 

    return view('jobs.edit', [ 
     'job' => $job 
    ]); 
} 

//destroy function 
public function destroy($id) 
{ 
    Job::find($id)->delete(); 

    return redirect()->route('jobs'); 
}

在你的路線

Route::post('delete','CallyourController@delete'); 
Route::post('update','CallyourController@update'); 

我認爲這是你想要做
