Preface

Generating HTML in PHP is always quite opinionated and limited. Blade Components are great because additional attributes are passed down to the element. That's why we prefer writing forms using components instead of using PHP builders. This way, you don't have to write extensions or custom code for any attribute you pass in. Let's take a look at this x-form example.

The action attribute is optional, but you can pass a hard-coded, primitive value to the component using a simple HTML attribute. PHP expressions and variables can be passed to the component as well via attributes that use the : character as a prefix. Do you need Alpine.js or VueJS directives? No problem!

<x-form action="/api/user">
    <!-- ... -->
</x-form>

<x-form :action="route('api.user.store')" v-on:submit="checkForm">
    <!-- ... -->
</x-form>

Configuration

You can switch frameworks by updating the framework setting in the form-components.php configuration file. Use the artisan vendor:publish command to publish the configuration file.

return [
    'framework' => 'bootstrap-4',
];

No further configuration is needed unless you want to customize the Blade views and components.

Usage

Input and textarea elements

The minimum requirement for an input or textarea is the name attribute.

<x-form-input name="company_name" />

Optionally you can add a label attribute, which can be computed as well.

<x-form-input name="company_name" label="Company name" />
<x-form-input name="company_name" :label="trans('forms.company_name')" />

You can also choose to use a placeholder instead of a label, and of course you can change the type of the element.

<x-form-input type="email" name="current_email" placeholder="Current email address" />

By default, every element shows validation errors, but you can hide them if you want.

<x-form-textarea name="description" :show-errors="false" />

Default value and binds

You can use the default attribute to specify the default value of the element.

<x-form-textarea name="motivation" default="I want to use this package because..." />

Binding a target

Instead of setting a default value, you can also pass in a target, like an Eloquent model. Now the component will get the value from the target by the name.

<x-form-textarea name="description" :bind="$video" />

In the example above, where $video is an Eloquent model, the default value will be $video->description.

Binding a target to multiple elements

You can also bind a target by using the @bind directive. This will bind the target to all elements until the @endbind directive.

<x-form>
    @bind($video)
        <x-form-input name="title" label="Title" />
        <x-form-textarea name="description" label="Description" />
    @endbind
</x-form>

You can even mix targets!

<x-form>
    @bind($user)
        <x-form-input name="full_name" label="Full name" />

        @bind($userProfile)
            <x-form-textarea name="biography" label="Biography" />
        @endbind

        <x-form-input name="email" label="Email address" />
    @endbind
</x-form>

Override or remove a binding

You can override the @bind directive by passing a target directly to the element using the :bind attribute. If you want to remove a binding for a specific element, pass in false.

<x-form>
    @bind($video)
        <x-form-input name="title" label="Title" />
        <x-form-input :bind="$videoDetails" name="subtitle" label="Subtitle" />
        <x-form-textarea :bind="false" name="description" label="Description" />
    @endbind
</x-form>

Laravel Livewire

You can use the @wire and @endwire directives to bind a form to a Livewire component. Let's take a look at the ContactForm example from the official Livewire documentation.

use Livewire\Component;

class ContactForm extends Component
{
    public $name;
    public $email;

    public function submit()
    {
        $this->validate([
            'name' => 'required|min:6',
            'email' => 'required|email',
        ]);

        Contact::create([
            'name' => $this->name,
            'email' => $this->email,
        ]);
    }

    public function render()
    {
        return view('livewire.contact-form');
    }
}

Normally you would use a wire:model attribute to bind a component property with a form element. By using the @wire directive, this package will automatically use the wire:model attribute instead of the name attribute.

<x-form wire:submit.prevent="submit">
    @wire
        <x-form-input name="name" />
        <x-form-input name="email" />
    @endwire

    <x-form-submit>Save Contact</x-form-submit>
</form>

Additionally, you can pass an optional modifier to the @wire directive. This feature was added in v2.4.0. If you're upgrading from a previous version and you published the Blade views, you should republish them or update them manually.

<x-form wire:submit.prevent="submit">
    @wire('debounce.500ms')
        <x-form-input name="email" />
    @endwire
</form>

Select elements

Besides the name attribute, the select element has a required options attribute, which should be a simple key-value array.

$countries = [
    'be' => 'Belgium',
    'nl' => 'The Netherlands',
];

<x-form-select name="country_code" :options="$countries" />

You can provide a slot to the select element as well:

<x-form-select name="country_code">
   <option value="be">Belgium</option>
   <option value="nl">The Netherlands</option>
</x-form-select>

If you want a select element where multiple options can be selected, add the multiple attribute to the element. If you specify a default, make sure it is an array. This applies to bound targets as well.

<x-form-select name="country_code[]" :options="$countries" multiple :default="['be', 'nl']" />

Using Eloquent relationships

This package has built-in support for BelongsToMany, MorphMany, and MorphToMany relationships. To utilize this feature, you must add both the multiple and many-relation attribute to the select element.

In the example below, you can attach one or more tags to the bound video. By using the many-relation attribute, it will correctly retrieve the selected options (attached tags) from the database.

<x-form>
    @bind($video)
        <x-form-select name="tags[]" :options="$tags" multiple many-relation />
    @endbind
</x-form>

Checkbox elements

Checkboxes have a default value of 1, but you can customize it as well.

<x-form-checkbox name="subscribe_to_newsletter" label="Subscribe to newsletter" />

If you have a fieldset of multiple checkboxes, you can group them together with the form-group component. This component has an optional label attribute and you can set the name as well. This is a great way to handle the validation of arrays. If you disable the errors on the individual checkboxes, it will one show the validation errors once. The form-group component has a show-errors attribute that defaults to true.

<x-form-group name="interests" label="Pick one or more interests">
    <x-form-checkbox name="interests[]" :show-errors="false" value="laravel" label="Laravel" />
    <x-form-checkbox name="interests[]" :show-errors="false" value="tailwindcss" label="Tailwind CSS" />
</x-form-group>

Radio elements

Radio elements behave exactly the same as checkboxes, except the show-errors attribute defaults to false as you almost always want to wrap multiple radio elements in a form-group.

You can group checkbox and radio elements on the same horizontal row by adding an inline attribute to the form-group element.

<x-form-group name="notification_channel" label="How do you want to receive your notifications?" inline>
    <x-form-radio name="notification_channel" value="mail" label="Mail" />
    <x-form-radio name="notification_channel" value="slack" label="Slack" />
</x-form-group>

When you're not using target binding, you can use the default attribute to mark a radio element as checked:

<x-form-group name="notification_channel" label="How do you want to receive your notifications?">
    <x-form-radio name="notification_channel" value="mail" label="Mail" default />
    <x-form-radio name="notification_channel" value="slack" label="Slack" />
</x-form-group>

Old input data

When a validation errors occurs and Laravel redirects you back, the form will be re-populated with the old input data. This old data will override any binding or default value.

Handling translations

This package supports spatie/laravel-translatable out of the box. You can add a language attribute to your element.

<x-form-input name="title" language="en" :bind="$book" />

This will result in the following HTML:

<input name="title[en]" value="Laravel: Up & Running" />

To get the validation errors from the session, the name of the input will be mapped to a dot notation like title.en. This is how old input data is handled as well.

Customize the blade views

Publish the configuration file and Blade views with the following command:

php artisan vendor:publish --provider="ProtoneMedia\LaravelFormComponents\Support\ServiceProvider"

You can find the Blade views in the resources/views/vendor/form-components folder. Optionally, in the form-components.php configuration file, you can change the location of the Blade view per component.

Component logic

You can bind your own component classes to any of the elements. In the form-components.php configuration file, you can change the class per component. As the logic for the components is quite complex, it is strongly recommended to duplicate the default component as a starting point and start editing. You'll find the default component classes in the vendor/protonemedia/laravel-form-components/src/Components folder.

Prefix the components

You can define a prefix in the form-components.php configuration file.

return [
    'prefix' => 'tailwind',
];

Now all components can be referenced like so:

<x-tailwind-form>
    <x-tailwind-form-input name="company_name" />
</x-tailwind-form>

Error messages

By the default, the errors messages are positioned under the element. To show these messages, we created a FormErrors component. You can manually use this component as well. The element takes an optional bag attribute to specify the ErrorBag, which defaults to default.

<x-form>
    <x-form-input name="company_name" :show-errors="false" />

    <!-- other elements -->

    <x-form-errors name="company_name" />

    <x-form-errors name="company_name" bag="register" />
</x-form>

Submit button

The label defaults to Submit, but you can use the slot to provide your own content.

<x-form-submit>
    <span class="text-green-500">Send</span>
</x-form-submit>

Bootstrap

You can switch to Bootstrap 4 or Bootstrap 5 by updating the framework setting in the form-components.php configuration file.

return [
    'framework' => 'bootstrap-5',
];

There is a little of styling added to the form.blade.php view to add support for inline form groups. If you want to change it or remove it, publish the assets and update the view file.

Bootstrap 5 changes a lot regarding forms. If you migrate from 4 to 5, make sure to read the migration logs about forms.

Input group / prepend and append

In addition to the Tailwind features, with Bootstrap 4, there is also support for input groups. Use the prepend and append slots to provide the contents.

<x-form-input name="username" label="Username">
    @slot('prepend')
        <span>@</span>
    @endslot
</x-form-input>

<x-form-input name="subdomain" label="Subdomain">
    @slot('append')
        <span>.protone.media</span>
    @endslot
</x-form-input>

With Bootstrap 5, the input groups have been simplified. You can add as many items as you would like in any order you would like. Use the form-input-group-text component to add text or checkboxes.

<x-form-input-group label="Profile" >
    <x-form-input name="name" placeholder="Name" id="name" />
    <x-form-input-group-text>@</x-form-input-group-text>
    <x-form-input name="nickname" placeholder="Nickname" id="nickname" />
    <x-form-submit />
</x-form-input-group>

Floating labels

As of Bootstrap 5, you can add floating labels by adding the floating attribute to inputs, selects (excluding multiple), and textareas.

<x-form-input label="Floating Label" name="float_me" id="float_me" floating />

Help text

You can add block-level help text to any element by using the help slot.

<x-form-input name="username" label="Username">
    @slot('help')
        <small class="form-text text-muted">
            Your username must be 8-20 characters long.
        </small>
    @endslot
</x-form-input>
