Input field not updating in the database - php

Question

I am working on a laravel 5.2 project. I am referencing category_id from Posts.
My Post model looks like
class Post extends Model
{
protected $fillable=['category_id '];
public function category(){
return $this->belongsTo('App\category');
}
}
Also, my form looks like
<div class="form-group">
{!! Form::label('category_id','Category:') !!}
{!! Form::select('category_id', $categories, '1',['class'=>'form-control']) !!}
</div>
My table data
#foreach($posts as $post)
<tr>
<td>{{$post->category['name']}}</td>
</tr>
#endforeach
The Problem is, whenever I create a new post, the category name doesn't save in the database nor does it show on the front end.
My Post Schema table
public function up()
{
Schema::create('posts', function (Blueprint $table) {
$table->increments('id');
$table->integer('category_id')->index()->unsigned()->nullable();
});
Even when I dd() the input field for the category id on the post table, its empty. Can someone help me with this, it's making me go crazy. Thanks
I am using a resource contoller,heres my create request controller
public function store(Request $request)
{
$user=Auth::user();
$input = $request->all();
Post::create($input);
return redirect('admin/posts');
}

Answer 1

It is because the fillable field only is the category_id try to add the category name field on your fillable like this.
//this are the fields that is fillable
protected $fillable=['category_id','name'];
With this the category name field will be able to catch and save data.

Answer 2

In continuation of my comment. Your migration should look like this.
public function up()
{
Schema::create('posts', function (Blueprint $table) {
$table->increments('id');
$table->integer('category_id')->index()->unsigned()->nullable();
$table->string('category_name')->nullable();
});
Your model,
class Post extends Model
{
protected $fillable=['category_id','category_name'];
}
Form
<div class="form-group">
{!! Form::label('category_id','Category:') !!}
{!! Form::select('category_id', $categories, '1',['class'=>'form-control']) !!}
{!! Form::input('category_name',old('category_name'),['class'=>'form-control', 'id' => "input_name"]) !!}
</div>
and lastly your table data should look like this.
#foreach($posts as $post)
<tr>
<td>{{$post->category_name}</td>
</tr>
#endforeach

Double check your fillable and input fields if they are the same.
your given concern you only show this one.
<div class="form-group">
{!! Form::label('category_id','Category:') !!}
{!! Form::select('category_id', $categories, '1',['class'=>'form-control']) !!}
</div>
how about the other fields. We expect you already had this on your form too.
<div class="form-group">
{!! Form::label('input_name','Name:') !!}
{!! Form::input('name',old('name'),['class'=>'form-control', 'id' => "input_name"]) !!}
</div>
In your store method it should look like this
$new_post = new Post;
$new_post->category_id = Input::get(‘category_id’);
$new_post->name = Input::get(‘name’);
$new_post->save();
Just in case you’re not using the fill method of $request

Answer 4

In order to access your relationship's attributes, you should do:
$post->comment->name;
And try to use 'fill()' when saving
$post = new Post;
$post->fill($request->all());
$post->save();

Answer 5

I fixed the error using this in my form.
{!! Form::select('category_id', [''=>'choose Categories'] + $categories,['class'=>'form-control']) !!}
and this on my table.
<td>{{$post->category['name']}}</td>
Thanks all for your effort.
