Creating a custom error message in laravel

Laravel has built-in error messages if a validation fails, but we may want to customize those
messages to make our application unique. This recipe shows a few different ways to create
custom error messages.

Getting ready

For this recipe, we just need a standard installation of Laravel.

How to do it…

To complete this recipe, follow these steps:
1. Create a route in routes.php to hold the form:
Route::get(‘myform’, function()
return View::make(‘myform’);

2. Create a view named myform.php and add a form:
<h1>User Info</h1>
<?php $messages = $errors->all
(‘<p style=”color:red”>:message</p>’) ?>
foreach ($messages as $msg)
echo $msg;
<?= Form::open() ?>
<?= Form::label(’email’, ‘Email’) ?>
<?= Form::text(’email’, Input::old(’email’)) ?>
<?= Form::label(‘username’, ‘Username’) ?>
<?= Form::text(‘username’, Input::old(‘username’)) ?>
<?= Form::label(‘password’, ‘Password’) ?>
<?= Form::password(‘password’) ?>

<?= Form::submit(‘Send it!’) ?>
<?= Form::close() ?>

3. Create a route that handles our POST data and validates it:
Route::post(‘myform’, array(‘before’ => ‘csrf’, function()
$rules = array(
’email’ => ‘required|email|min:6’,
‘username’ => ‘required|min:6’,
‘password’ => ‘required’
$messages = array(
‘min’ => ‘Way too short! The :attribute must be at
least :min characters in length.’,
‘username.required’ => ‘We really, really need a
$validation = Validator::make(Input::all(), $rules,
if ($validation->fails())
return Redirect::to(‘myform’)->withErrors

return Redirect::to(‘myresults’)->withInput();

4. Open the file app/lang/en/validation.php, where en is the default language
of the app. In our case, we’re using English. At the bottom of the file, update the
attributes array as the following:
‘attributes’ => array(
‘password’ => ‘Super Secret Password (shhhh!)’

5. Create a route to handle a successful form submission:
Route::get(‘myresults’, function()
return dd(Input::old());

How it works…

We first create a fairly simple form, and since we aren’t passing any parameters to
Form::open(), it will POST the data to the same URL. We then create a route to accept the
POST data and validate it. As a best practice, we’re also adding in the csrf filter before our
post route. This will provide some extra security against cross-site request frogeries.
The first variable we set in our post route will hold our rules. The next variable will hold any
custom messages we want to use if there’s an error. There are a few different ways to set
the message.
The first message to customize is for min size. In this case, it will display the same message
for any validation errors where there’s a min rule. We can use :attribute and :min to hold
the form field name and minimum size when the error is displayed.
Our second message is used only for a specific form field and for a specific validation rule. We
put the form field name first, followed by a period, and then the rule. Here, we are checking
whether the username is required and setting the error message.
Our third message is set in the language file for validations. In the attributes array, we
can set any of our form field names to display any custom text we’d like. Also, if we decide to
customize a particular error message across the entire application, we can alter the default
message at the top of this file.
