To pre-populate form field, we can add \'value\' to form field in create.blade.php:

{{ Form::text(\'title\', \'Some default title\') }}

Is ther

    Yes, let's consider the following example:

    View:

    {{ Form::text('title', $title) }}

    Controller:

    $title = 'Some default title';
if($article) {
    $title = $article->title;
}
return View::make('user.login')->with('title', $title)

    Then you will have a text-input with either Some default title or the title from $article, if $article isn't equal to false

    Okay, so here we are... I used Laravel's form model binding in the example. (I work with User model/db table). If this topic is not clear for you, take a look at this http://laravel.com/docs/html#form-model-binding

    // Controller

class UsersController extends BaseController
{

    ...

    // Method to show 'create' form & initialize 'blank' user's object
    public function create()
    {
        $user = new User;
        return View::make('users.form', compact('user'));
    }

    // This method should store data sent form form (for new user)
    public function store()
    {
        print_r(Input::all());
    }

    // Retrieve user's data from DB by given ID & show 'edit' form   
    public function edit($id)
    {
        $user = User::find($id);
        return View::make('users.form', compact('user'));
    }

    // Here you should process form data for user that exists already.
    // Modify/convert some input data maybe, save it then...
    public function update($id)
    {
        $user = User::find($id);
        print_r($user->toArray());
    }

    ...

}

    And here come the view file served by controller.

    // The view file - self describing I think
<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<body>
    @if(!$user->id)
    {{ Form::model($user, ['route' => 'admin.users.store']) }}
    @else
    {{ Form::model($user, ['route' => ['admin.users.update', $user->id], 'method' => 'put']) }}
    @endif
        {{ Form::text('firstName') }}

        {{ Form::text('lastName') }}

        {{ Form::submit() }}
    {{ Form::close() }}
</body>
</html>

    All you need to do is include a conditional in your blade template.

    Lets assume your database table has a field myfield, which you want to default to mydefault.

    Just include the following in a partial view which is called by the create and edit views:

    @if(isset($myfield))
{{ Form::input('text','myfield') }}
@else
{{ Form::input('text','myfield','mydefault') }}
@endif

    You don't have to anything else.

    if you mean placeholder you can do this

    {{ Form::password('password', array('placeholder' => 'password'))}}

    When you are using the Schema builder (in Migrations or somewhere else):

    Schema::create( 
      'posts', function($table) {
          $table->string('title', 30)->default('New post'); 
      }
);

    If you want to do this conditionally, an alternative method of solving this could be to perform a check instead. If this check passes, set the default (as is done below with $nom as an example). Otherwise, leave it empty by setting it to null explicitly.

    {{ Form::text('title', (isset($nom)) ? $nom : null) }}
