Handling uploads with Livewire 2

Getting started

Make sure to have followed Livewire's installation instructions.

Make sure Alpine is available on the page as well. The easiest way is to include it from a CDN:

<script src="https://cdn.jsdelivr.net/gh/alpinejs/alpine@v2.6.0/dist/alpine.min.js" defer></script>

Visit the Alpine repo for more installation options.

Demo application

In the v2 btranch of this repo on GitHub, you'll find a demo Laravel application in which you'll find examples of how to use Media Library Pro inside your Livewire components.

If you are having troubles using the components, take a look in that app to see how we've done it.

Handling a single upload

You can use x-media-library-attachment component to upload a single file.

Here's how that might look like in the view of your Livewire component:

<form method="POST" wire:submit.prevent="submit">
   
    <input id="name" wire:model.debounce.500ms="name">

    <x-media-library-attachment name="myUpload" />

    <button type="submit">Submit</button>
</form>

In your Livewire component you must:

use the Spatie\MediaLibraryPro\Http\Livewire\Concerns\WithMedia trait
add a public property $mediaComponentNames array that contains all the names of media library pro components that you are going to use.
for each component that you are going to use you should add a public property with the name you use in the view for that component (in the example above: myUpload)

Here is an example component:

namespace App\Http\Livewire;

use App\Models\YourModel;
use Livewire\Component;
use Spatie\MediaLibraryPro\Http\Livewire\Concerns\WithMedia;

class MyForm extends Component
{
    use WithMedia;

    public $name;

    public $message = '';

    public $mediaComponentNames = ['myUpload'];

    public $myUpload;

    public function submit()
    {
        $formSubmission = YourModel::create([
            'name' => $this->name,
        ]);

        $formSubmission
            ->addFromMediaLibraryRequest($this->myUpload)
            ->toMediaCollection('images');

        $this->message = 'Your form has been submitted';

        $this->name = '';
        $this->clearMedia();
    }

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

Immediately after a file has been uploaded it will be stored as a temporary upload. In the method that handles the form submission you must use the addFromMediaLibraryRequest method to move the uploaded file to the model you want.

To clear out an uploaded file from being displayed, you can call clearMedia(). This method will only clear the uploaded file from view, uploaded files will not be deleted.

If you are using multiple attachment components and only want to clear out specific ones, pass the name of the component to clearMedia.

$this->clearMedia('myUpload')

Validating a single upload

You can pass any Laravel validation rule to the rules prop of the x-media-library-attachment component. Here's an example where only jpeg and png will be accepted.

<x-media-library-attachment name="myUpload" rules="mimes:jpeg,png"/>

You can make the upload required by validating it in your Livewire component:

// in the method that handles the form submission inside your livewire component

public function submit()
{
    $this->validate([
        'myUpload' => 'required',
    ]);
    
    // process the form submission
}

Handling multiple uploads

Uploading multiple files is very similar to uploading a single file. The only thing you need to add to the x-medialibrary-attachment in the view is multiple.

<form method="POST" wire:submit.prevent="submit">
   
    <input id="name" wire:model.debounce.500ms="name">

    <x-media-library-attachment multiple name="images" />

    <button type="submit">Submit</button>
</form>

In your Livewire component you must:

use the Spatie\MediaLibraryPro\Http\Livewire\Concerns\WithMedia trait
add a public property $mediaComponentNames that contains all the names of media library pro components that you are going to use.
for each component that you are going to use you should add a public property with the name you use in the view for that component (in the example above: myUpload)

Here is an example component:

namespace App\Http\Livewire;

use App\Models\YourModel;
use Livewire\Component;
use Spatie\MediaLibraryPro\Http\Livewire\Concerns\WithMedia;

class MyForm extends Component
{
    use WithMedia;

    public $name;

    public $message = '';

    public $mediaComponentNames = ['images'];

    public $images;

    public function submit()
    {
        $formSubmission = YourModel::create([
            'name' => $this->name,
        ]);

        $formSubmission
            ->addFromMediaLibraryRequest($this->images)
            ->toMediaCollection('images');

        $this->message = 'Your form has been submitted';

        $this->name = '';
        
        $this->clearMedia();
    }

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

Validating multiple uploads

You can pass any Laravel validation rule to the rules prop of the x-media-library-attachment component. Here's an example where only jpeg and png will be accepted.

<x-media-library-attachment name="images" rules="mimes:jpeg,png"/>

You can make the upload required by validating it in your Livewire component. Here's an example where at least one upload is required, but more than three uploads are not allowed.

// in the method that handles the form submission inside your livewire component

public function submit()
{
    $this->validate([
        'images' => 'required|max:3',
    ]);
    
    // process the form submission
}

Administer the contents of a media library collection

You can manage the entire contents of a media library collection with x-media-library-collection component. This component is intended for use in admin sections.

Here is an example where we are going to administer an images collection of a $blogPost model. We assume that you already prepared the model to handle uploads.

<form method="POST" wire:submit.prevent="submit">

    <input id="name" wire:model.debounce.500ms="name">

    <x-media-library-collection
        name="images"
        :model="$blogPost"
        collection="images"
    />

    <button type="submit">Submit</button>
</form>

In your Livewire component you must:

use the Spatie\MediaLibraryPro\Http\Livewire\Concerns\WithMedia trait
add a public property $mediaComponentNames array that contains all the names of media library pro components that you are going to use.
for each component that you are going to use you should add a public property with the name you use in the view for that component (in the example above: myUpload)

Here is an example component:

namespace App\Http\Livewire;

use App\Models\BlogPost;
use Livewire\Component;
use Spatie\MediaLibraryPro\Http\Livewire\Concerns\WithMedia;

class MyForm extends Component
{
    use WithMedia;

    public $name;

    public $message = '';

    public $mediaComponentNames = ['images'];

    public $images;

    public function submit()
    {
        $formSubmission = BlogPost::create([
            'name' => $this->name,
        ]);

        $formSubmission
            ->addFromMediaLibraryRequest($this->images)
            ->toMediaCollection('images');

        $this->message = 'Your form has been submitted';       
    }

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

Validating the collection

You can pass any Laravel validation rule to the rules prop of the x-media-library-collection component. Here's an example where only jpeg and png will be accepted.

<x-media-library-collection name="images" rules="mimes:jpeg,png"/>

You can make the upload required by validating it in your Livewire component. Here's an example where at least one upload is required, but more than three uploads are not allowed.

// in the method that handles the form submission inside your livewire component

public function submit()
{
    $this->validate([
        'images' => 'required|max:3',
    ]);
    
    // process the form submission
}

Using custom properties

Media library supports custom properties to be saved on a media item. By default, the x-media-library-collection component doesn't show the custom properties. To add them you should create a blade view that will be used to display all form elements on a row in the component.

In this example we're going to add a custom property form field called extra_field.

@include('medialibrary::livewire.partials.collection.fields')

<div class="media-library-field">
    <label class="media-library-label">Extra field</label>
    <input
        class="media-library-input"
        type="text"
        {{ $mediaItem->livewireCustomPropertyAttributes('extra_field') }}
    />

    @error($mediaItem->customPropertyErrorName('extra_field'))
    <span class="media-library-text-error">
       {{ $message }}
    </span>
    @enderror
</div>

You should then pass the path to that view to the fields-view prop of the x-media-library-collection component.

<x-media-library-collection
    name="images"
    :model="$formSubmission"
    collection="images"
    fields-view="app.your-custom-properties-blade-view-path"
/>

This is how that will look like.

In your Livewire component, you can validate the custom properties like this. This example assumes that you have set the name attribute of x-media-library-collection to images.

// inside the method in your Livewire component that handles the form submission
public function submit()
{
    $this->validate([
        'images.*.custom_properties.extra_field' => 'required',
    ], ['required' => 'This field is required']);

    // process the form submission
}

Uploading directly to S3

Currently, Livewire does not support uploading multiple files to S3. That's why only the attachment component can be used to upload files to S3.

To get started with uploading files to s3, make sure to follow Livewire's instructions on how to upload directly to S3.

Next, make sure you have configured the media disk that uses the S3 driver.

With that configuration in place, the attachment component will now upload directly to S3.
