Error

The error component provides an easy way to work with Laravel's $error message bag in its Blade views. You can use it to display (multiple) error messages for form fields.

Basic Usage

Imagine we have the following validation errors:

['first_name' => 'Incorrect first name.']

The most basic usage of the error component is as a self-closing component with a field attribute:

<x-error field="first_name" class="invalid-feedback" />

This will output the following HTML:

<div class="invalid-feedback">
    Incorrect first name.
</div>

As you can see it'll pick the error message from the $error message bag and render it in the view. If the message isn't set, the HTML isn't rendered.

Composing The Content

You can also opt to customize the structure of the rendered content. This allows you to make use of the component's messages() method to, for example, render multiple validation errors at the same time.

Let's assume we have the following validation errors:

[
    'first_name' => [
        'Incorrect first name.',
        'Needs at least 5 characters.',
    ]
]

Now we'll use the component's slot and its messages() method to render an unorderd list of the errors:

<x-error field="first_name">
    <ul>
        @foreach ($component->messages($errors) as $error)
            <li>{{ $error }}</li>
        @endforeach
    </ul>
</x-error>

This will output the following HTML:

<div>
    <ul>
        <li>Incorrect first name.</li>
        <li>Needs at least 5 characters.</li>
    </ul>
</div>

As you can see we need to pass in the $errors message bag to the messages() method of the component to grab all the messages for our field. Then we loop over them and render them.
