Laravel 5.3 Form Builder Assign 'value' Dynamically on Select Options - php

Question

How do i assign the 'value' on the Laravel Form Builder Select Options dynamically in my views?
Example:
Function
public function create()
{
$categories = \DB::table('categories')->pluck('name', 'id');
return view('link.create')->with('categories', $categories);
}
View
<div class="form-group">
{!! Form::label('Link Category') !!}<br />
{!! Form::select('category',
(['0' => 'Select a Category'] + $categories),
null,
['class' => 'form-control']) !!}
</div>
Result
<select name="category" class="form-control">
<option value="0">Select a Category</option>
<option value="1">Laravel</option>
<option value="2">Zend Framework</option>
<option value="3">CakePHP</option>
<option value="4">PHP</option>
</select>
I would like the 'value' of the Select Options to be identical to the Option Content.
Like:
<option value="1">Laravel</option>
Should be like:
<option value="Laravel">Laravel</option>

Answer 1

If you pluck only the name, you can do something like this:
public function create()
{
$categories = \DB::table('categories')->pluck('name');
// creates ['Laravel' => 'Laravel', 'PHP' => 'PHP'...]
$categories = array_combine($categories, $categories);
return view('link.create')->with('categories', $categories);
}

Answer 2

You can just pluck name for both key and value
public function create()
{
$categories = \DB::table('categories')->pluck('name', 'name');
// Combine your default item
$categories = ['0' => 'Select a Category'] + collect($categories)->toArray();
return view('link.create')->with('categories', $categories);
}
Your view modified as below
<div class="form-group">
{!! Form::label('Link Category') !!}<br />
{!! Form::select('category', $categories, null, ['class' => 'form-control']) !!}
</div>
