Unable to show anything on edit form

I seem to unable to get the data from the database and display it on the edit form and when i checked all the syntax and the codes it doesnt seem to go wrong

My Model:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Buku extends Model
{
    //
}

This is my Controller code for edit:

public function edit($id)
    {
        // find a post in the database and save as a variable
        $post = Buku::find($id);

        // return the view and pass in the variable we previously created
        return view('buku.edit')->with('buku', $post);
    }

Here is my view in for my edit form, I am using bootstrap modal for the form:

<div class="modal fade" id="edit_buku" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">

      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Edit Buku</h4>
      </div>

      <div class="modal-body">
      @if (isset($post))
        {!! Form::model($post, array('route' => array('buku.update' , $post->id), 'method' => 'PUT')) !!}
        @endif
            <div class="form-group">
              {{ Form::label('judul','Judul') }}
              {{ Form::text('judul', null, ["class" => 'form-control']) }}
            </div>
            <div class="form-group">
              {{ Form::label('deskripsi','Deskripsi') }}
              {{ Form::text('deskripsi', null, ["class" => 'form-control']) }}
            </div>
            <div class="form-group">
             {{ Form::label('pengarang','Pengarang') }}
             {{ Form::text('pengarang', null, ["class" => 'form-control']) }}
            </div>
            <div class="form-group">
             {{ Form::label('tanggal_publikasi','Tanggal Publikasi') }}
             {{ Form::text('tanggal_publikasi', null, ["class" => 'form-control']) }}
            </div>
      </div>
      <div class="modal-footer">
      {{ Form::submit('Edit', array('class' => 'btn btn-success')) }}   
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        {!! Form::close() !!}
      </div>
    </div>
  </div>
</div>

Note that i have to use the if isset to actually prevent an error called the Undefined variable error on my $post but it seems to not actually pass the value from the my database to the fields... I was wondering if the isset function is the cause.. I have tried to put the endif at the bottom of the code and the whole modal will not appear when I click on the link

Any help is appreciated..

I notice in your controller you use ->with('buku', $post). This will send a variable called $buku along to the view, containing the buku that was found using $post = Buku::find($id);. Change that line to ->with('post', $post).

Secondly, I generally use if (!empty($post)) instead of isset, since empty() evaluates both if it is set and if it is empty. According to http://php.net/manual/en/function.empty.php: No warning is generated if the variable does not exist. That means empty() is essentially the concise equivalent to !isset($var) || $var == false.

Thirdly, put your @endif after your Form::close().

Fourthly, test to see if $post actually contains data. Either {!! dd($post) !!} before your if statement or use else to echo some text.

Hope this helps.

Firstly, i suggest to change your controller as follow:

public function edit($id)
{
    // find a post in the database and save as a variable
    $post = Buku::find($id);

    // return the view and pass in the variable we previously created
    return view('buku.edit')->with('post', $post);
}

I guess, it should solve your problem. Read more about passwing variables to views: https://laravel.com/docs/5.2/views#passing-data-to-views
