与数据库的laravel下拉列表

Question

i'm a newbie to laravel framework and i just find it's so hard to understanding laravel form usability.... so here is some issue that i face into

First my dropdown should be having my categories name and at the very end of dropdown it will be my specific dropdown add new categories that when i selected will trigger my javascript... and im here is my form code

{{ Form::select('kategori',KategoriArtikel::lists('name','id'),Input::old('kategori'),array('class' => 'form-control', 'onChange' => 'changeFunc(value)')) }}

that will show right value from my database also with right selected value but it's missing my specific dropdown, so i tried to add like this

 <?php 
     $tambah = array('tambah' => 'Tambah Kategori Baru');
     $list = array_merge(KategoriArtikel::lists('name','id'),$tambah); 
 ?>
{{ Form::select('kategori',array(KategoriArtikel::lists('name','id'),$tambah),Input::old('kategori'),array('class' => 'form-control', 'onChange' => 'changeFunc(value)')) }}

but it will generate 2 with different layout (which ugly) and not showing right selected value, so i tried other way

 <?php 
     $tambah = array('tambah' => 'Tambah Kategori Baru');
     $list = array_merge(KategoriArtikel::lists('name','id'),$tambah); 
?>
{{ Form::select('kategori',$list,Input::old('kategori'),array('class' => 'form-control', 'onChange' => 'changeFunc(value)')) }}

and it not generate and my dropdown layout is what it supposed to be but now the is not from my table id anymore but just sequential number 0,1,2,3,etc any solution to that?

Second problem is when i submit my form, it's not working, my field in table is int and when i submit it just not saving/updating so i tried to dd(Input::all()) and my dropdown is returning string of selected option value and it's not saved into my table... so why is that? it also not working for my boolean field that contain tinyint(1)... so basicly all value returning string.

its returning this

array(8) { ["_method"]=> string(3) "PUT" ["_token"]=> string(40) "IspUKdCETMe4Nn3pDI43GI7aJKQfXpupJvQAy1k6" ["simpan"]=> string(6) "simpan" ["judul"]=> string(18) "test "kegiatan" 21" ["kategori"]=> string(1) "9" ["kategori_baru"]=> string(0) "" ["status"]=> string(1) "0" ["content"]=> string(1012) "
I used--and I don't put my arm round your waist,' the Duchess said to herself. 'Of the mushroom,' said the Dormouse, and repeated her question. 'Why did they live at the sides of it, and then turned to the tarts on the twelfth?' Alice went on, 'that they'd let Dinah stop in the shade: however, the moment he was obliged to have wondered at this, but at the Caterpillar's making such a capital one for catching mice--oh, I beg your pardon!' cried Alice hastily, afraid that she had read about them in books, and she at once without waiting for turns, quarrelling all the children she knew, who might do something better with the time,' she said to herself; 'I should like to drop the jar for fear of killing somebody, so managed to swallow a morsel of the house, quite forgetting her promise. 'Treacle,' said the Gryphon: and it sat for a few minutes to see if she had grown up,' she said this, she looked down at her as she wandered about for it, you know--' (pointing with his head!' she said,.

" }

and as you can see ['kategori'] is supposed to be making my field kategori in my table to be 9 but it's not changing anything in my database

well i laravel simplicity but it's very confusing when working with database (can't find any documentation example related to databas retrieving data and so on)

edit:

this is my controller

public function update($id)
{
    $artikel = Artikel::findOrFail($id);

    if(Input::get('simpan')){
        //dd(Input::all());

        $validator = Validator::make($data = Input::all(), Artikel::$rules);

        if ($validator->fails())
        {
            return Redirect::back()->withErrors($validator)->withInput();
        }

        $judul = Input::get('judul');
        $artikel->update($data);

        return Redirect::route('admin.artikels.index')->with('message', 'Artikel ' .$judul. ' Telah berhasil di ubah.');
    }elseif(Input::get('batal')){
        return $this->index();
    }
}

and here is my view

@extends('admin._layouts.admin')

@section('content')
{{ Form::model($artikel, array('route' => array('admin.artikels.update',$artikel->id), 'method' => 'put')) }}
    <div class="panel panel-default">

               'data-placement' => 'top','title' => 'Menyimpan artikel' )) }}
            {{ Form::submit('Batal',array('class' => 'btn btn-default', 'data-toggle' => 'tooltip', 
               'data-placement' => 'top','title' => 'Batal menambah artikel dan kembali ke halaman kelola artikel' )) }}

Answer 1

If I have understood your problem correctly, you want to populate a dropdown based on values from database and also want to display "Select A Category" in the category dropdown. And currently your dropdown values are not being saved.

To populate the dropdown put the following code your controller's method through which you are loading the view file.

$data['kategori'] = KategoriArtikel::lists('name','id');
$data['kategori'][''] = 'Select a kategori';        
return View::make('YOUR_VIEW_FILE', $data); 

In your view file, simple use the following, (same rules apply for other select dropdowns):

{{ Form::select('kategori', $kategori , Input::old('kategori'), array('id' => 'category', 'class' => 'form-control',  )) }} 

The above code basically generates something like this:

<select id="category" class="form-control">
  <option value="">Select a Kategori</option>
  <option value="1">First Kategori</option>
  <option value="2">Second Kategori</option>
</select>

The third parameter in Form::select() expects a default option value, if you provide a value it will compare with option values and display the matched one as selected.

And Your form's method shouldn't be 'method' => 'POST' not 'method' => 'put'
