Laravel3: Loading a content inside a content dynamically - php

Question

I have a form. When user submits the form and gets error, I show it like this:
Register Controller
return View::make('theme-admin.user_add')->with('error_msg', validation->errors->first());
register.blade.php
#if($error_msg !== null)
<div class="alert red hideit max">
<div class="left">
<span class="red-icon"></span>
<span class="alert-text">{{ $error_msg }}</span> <-- Error message is visible here.
</div>
<div class="right">
<a class="close-red"></a>
</div>
</div>
#endif
//
Actual HTML Form
//
However, I want to move that error div into a blade file. (error.blade.php) and I want to call it with parameters when there is an error.
It will look like this.
NEW register.blade.php
{{ MESSAGE_CONTENT }} //This should be replaced with error.blade.php dynamically
//
Actual HTML Form
//
MESSAGE_CONTENT will be included via error.blade.php
error.blade.php
<div class="alert red hideit max">
<div class="left">
<span class="red-icon"></span>
<span class="alert-text">{{ $message }}</span> <-- Error message is visible here.
</div>
<div class="right">
<a class="close-red"></a>
</div>
</div>
Let's say form failed and I got some errors. I will load error.blade.php so messages will get RED background etc.
Something like this;
return View::make('theme-admin.user_add')->with(message_content', (Load error.blade.php here))->with('message', $validation->errors->first();
If the form succeeds, I'll just load success.blade.php in messages area and messages will look with GREEN background.
return View::make('theme-admin.user_add')->with(message_content', (Load success.blade.php here))->with('message', 'You successfully registered');
You probably got the logic.
How can I do this?

A clean solution may be to have a simple alert object with a type and msg.
//in controller
$alert->type = 'error'; // or 'success'
$alert->class = 'red'; // or 'green'
$alert->msg = $validation->errors->first(); // or 'You successfully registered'
return View::make('theme-admin.user_add')->with('alert', $alert);
//register.blade.php
#include('alert')
//Actual HTML Form
//alert.blade.php
#if(isset($alert))
<div class="alert {{$alert->class}} hideit max">
<div class="left">
<span class="red-icon"></span>
<span class="alert-text">{{ $alert->msg }}</span>
</div>
<div class="right">
<a class="close-{{$alert->class}}"></a>
</div>
</div>
#endif

You should create your view (View::make()) in a route defined for GET, and then handle your form input in your POST route:
//routes.php
Route::get('admin/adduser', array('as' => 'adduser', 'do' => function()
{
return View::make('theme-admin.user_add');
}));
//route for handling form input
Route::post('register', array('before' => 'csrf', function()
{
$rules = array(
//your vailidation rules here..
);
$validation = Validator::make(Input::all(), $rules);
if ($validation->fails())
{
//re-populate form if invalid values, so add flashing input by with_input()
//also pass errors by using with_errors
return Redirect::to('adduser')->with_input()->with_errors($validation);
}
else {
//use the named route we defined in Route:get above
return Redirect:to('adduser')->with('message', 'Successfully added the new user!');
}
}));
There is no need to create new views for dislaying error and success messages. If you want to seperate your success and error into their own blade templates then you could use the following in your adduser.blade.php:
//adduser.blade.php
#if($errors->has())
#include('errormsg'); //use {{ $errors->first() }} or #foreach($errors->all() as $message) to print error message(s)
#else
#include('success'); //use {{ $message }} to print success
#endif
However you can also use sections in your view, and instead put both the success and error message inside the same view:
//feedback.blade.php
#section('error')
<em class="error">{{ $errors->first() }}</em>
#endsection
#section('success')
<em class="success">{{ $message }}</em>
#endsection
//adduser.blade.php
#include('feedback');
#if($errors->has())
#yield('error');
#else
#yield('success');
#endif
Hope that helps.

I found the solution myself. I needed Nested Views feature.
$view = View::make('home');
$view->nest('content', 'orders', array('orders' => $orders));
Refer to Laravel documentation for more information.
