README

Livewire Filters is a series of Livewire components that provide you with the tools to do live filtering of your data from your own Livewire components.

Requirements

This package requires Laravel 9.0+ and Livewire 2.10+.

Installation

To get started, require the package via Composer:

composer require kirschbaum-development/livewire-filters

Publishing views

The included filters are made with Tailwind CSS and the Tailwind CSS Forms plugin. We recommend publishing the views and changing the markup to match whatever styling or CSS framework your project uses.

php artisan vendor:publish --tag=livewire-filters-views

Publishing config

Publishing the config file is only necessary to enable query string usage.

php artisan vendor:publish --tag=livewire-filters-config

Usage

Define your filters

You can use filters in your Livewire component by including the HasFilters trait provided by the package.

With the trait included, define a filters method that returns an array of Filter objects you want to use in your component. The included Filter class has a series of fluent methods for building up the specifics of each of your filters.

use HasFilters;

public function filters(): array
{
    return [
        Filter::make('title'),
        Filter::make('type')->options(['text', 'link', 'audio', 'video'])->default(['audio']),
        Filter::make('status')->options(['published', 'draft'])->default('published'),
    ];
}

Use your filters

With your component setup, you can include filters in the view file of your Livewire component. In order to setup the filter, simply use one of the filter components and pass the specific filter by its key. The component will take care of setting itself up.

<livewire:livewire-filters-checkbox :filter="$filters['type']" />

There is more information below about the included filters in the package.

Determining filtered status/count

The HasFilters trait includes two computed properties you can use to determine if there are active filters and how many of your filters are currently active. You can access these directly in your Livewire component by using $this->isFiltered or $this->activeFilterCount. You can also pass one or both of these properties to your Livewire component through the render method if you so choose.

These computed properties are handy if you want to change the color of a button, show/hide a specific section of your UI, show a badge of active filters, or simply show a visual indicator that there are active filters being applied.

Getting filtered values

Because the $filters array contains Filter objects, you will need to either access the value property, use the value() method, or use the included getFilterValue($key) helper method.

// Helper included in the HasFilters trait
$this->getFilteredValue('type');

// Using the accessor
$this->filters['type']->value();

// Using the property directly
$this->filters['type']->value;

Example parent component

use App\Models\Post;
use Kirschbaum\LivewireFilters\Filter;
use Kirschbaum\LivewireFilters\HasFilters;
use Livewire\Component;

class PostsList extends Component
{
    use HasFilters;

    public function filters(): array
    {
        return [
            Filter::make('type')->options(['text', 'link', 'audio', 'video'])->default(['text', 'link']),
        ];
    }

    public function getPostsProperty()
    {
        return Post::query()
            ->when($this->getFilterValue('type'), fn ($query, $values) => $query->whereIn('type', $values))
            ->paginate();
    }

    public function render()
    {
        return view('livewire.posts-list', [
            'filterCount' => $this->filterCount,
            'isFiltered' => $this->isFiltered,
            'posts' => $this->posts,
        ]);
    }
}

Included filters

The package includes 4 basic filters that can be used in your Livewire components.

Checkbox filter

The checkbox filter allows you to select any number of options. Every time a change is made, the filter will emit an event with an array of the currently checked values.

<livewire:livewire-filters-checkbox :filter="$filters['type']" />

Radio button filter

The radio button filter allows you to select a single option from the list of options. Every time a change is made, the filter will emit an event with the currently checked value.

<livewire:livewire-filters-radio :filter="$filters['type']" />

Select menu filter

Similar to the radio button filter, the select menu filter allows you to select a single option from the list of options from a select menu. Every time a change is made, the filter will emit an event with the currently selected value.

<livewire:livewire-filters-select :filter="$filters['type']" />

Text box filter

The text box filter allows you to type freeform text that you can use for filtering. Every time a change is made, the filter will emit an event with the value of the text field.

<livewire:livewire-filters-text :filter="$filters['type']" />

The Filter class

The Filter class provides a fluent interface for defining filters in your Livewire component as well as retrieving information about the filter.

make($key)

The first method you must call is the make method and pass it a unique key. After this method has been called, you can call any of the other methods in whatever order you want.

options($values)

If you're using a filter that requires options, you can pass an array of those values into the options method. Calling the options method without any arguments will return the defined options for the filter.

value($values)

If you would like to set the value of a filter, you can pass the value or an array of values into the value method. Calling the value method without any arguments will return the current value of the filter.

default($values)

When defining a filter, you should use the default method to set the initial value of the filter. This will store the initial value on the object as well to help with determining the status of active filters as well as resetting the filter to its original state. Calling the default method without any arguments will return the initial value that you specified when you defined the filter.

meta(array $values)

If you would like to set additional information on the filter to be used in the view file, you can pass an array of values into the meta method. Calling the meta method without any arguments will return the current array of meta information.

Events

livewire-filters-reset

livewire-filters-updated

When a filter is updated, it will emit this event with 2 arguments: key and payload. The key should be used in identifying which filter should be updated. The payload is the new value of the filter.

This event is automatically handled by the HasFilters trait. If you would like to customize how the updates are handled, you can listen for this event and use your own method or override the handleUpdateEvent method.

Making your own filters

In addition to the included filters, you can also make additional filters to suit your needs.

use Kirschbaum\LivewireFilters\FilterComponent;

class DateFilter extends FilterComponent
{
    public function render()
    {
        return view('livewire.filters.date-filter');
    }
}

<div
    x-data
    x-init="window.flatpickr($refs.flatpickr)"
>
    <input
        type="text"
        name="{{ $key }}"
        id="{{ $key }}"
        class="focus:ring-indigo-500 focus:border-indigo-500 block w-full pr-8 sm:text-sm border-gray-300 rounded-md"
        placeholder="Select a date..."
        readonly="readonly"
        x-ref="flatpickr"
        wire:model="value"
    >

    @if ($value !== $initialValue)
        <div class="absolute inset-y-0 right-2 flex items-center">
            <button type="button" class="text-gray-400 hover:text-gray-500" wire:click="resetValue">
                <svg xmlns="http://www.w3.org/2000/svg" class="h-5 w-5" viewBox="0 0 20 20" fill="currentColor"><path fill-rule="evenodd" d="M4.293 4.293a1 1 0 011.414 0L10 8.586l4.293-4.293a1 1 0 111.414 1.414L11.414 10l4.293 4.293a1 1 0 01-1.414 1.414L10 11.414l-4.293 4.293a1 1 0 01-1.414-1.414L8.586 10 4.293 5.707a1 1 0 010-1.414z" clip-rule="evenodd" /></svg>
                <span class="sr-only">Reset</span>
