Installation

Install via Composer:

$ composer require log1x/acf-composer

Usage

Getting Started

Start by publishing the config/acf.php configuration file using Acorn:

$ wp acorn vendor:publish --tag="acf-composer"

Generating a Field

To create your first field, start by running the following generator command from your theme directory:

$ wp acorn acf:field Example

This will create src/Fields/Example.php which is where you will create and manage your first field group.

Taking a glance at the generated Example.php stub, you will notice that it has a simple list configured.

<?php

namespace App\Fields;

use Log1x\AcfComposer\Builder;
use Log1x\AcfComposer\Field;

class Example extends Field
{
    /**
     * The field group.
     *
     * @return array
     */
    public function fields()
    {
        $example = Builder::make('example');

        $example
            ->setLocation('post_type', '==', 'post');

        $example
            ->addRepeater('items')
                ->addText('item')
            ->endRepeater();

        return $example->build();
    }
}

Proceed by checking the Add Post for the field to ensure things are working as intended – and then get to work.

Generating a Field Partial

A field partial consists of a field group that can be re-used and/or added to existing field groups.

To start, let's generate a partial called ListItems that we can use in the Example field we generated above.

$ wp acorn acf:partial ListItems

<?php

namespace App\Fields\Partials;

use Log1x\AcfComposer\Builder;
use Log1x\AcfComposer\Partial;

class ListItems extends Partial
{
    /**
     * The partial field group.
     *
     * @return array
     */
    public function fields()
    {
        $listItems = Builder::make('listItems');

        $listItems
            ->addRepeater('items')
                ->addText('item')
            ->endRepeater();

        return $listItems;
    }
}

Looking at ListItems.php, you will see out of the box it consists of an identical list repeater as seen in your generated field.

A key difference to note compared to an ordinary field is the omitting of ->build() instead returning the FieldsBuilder instance itself.

This can be utilized in our Example field by passing the ::class constant to ->addPartial():

<?php

namespace App\Fields;

use App\Fields\Partials\ListItems;
use Log1x\AcfComposer\Builder;
use Log1x\AcfComposer\Field;

class Example extends Field
{
    /**
     * The field group.
     *
     * @return array
     */
    public function fields()
    {
        $example = Builder::make('example');

        $example
            ->setLocation('post_type', '==', 'post');

        $example
            ->addPartial(ListItems::class);

        return $example->build();
    }
}

Generating a Block

Generating a block is generally the same as generating a field as seen above.

Start by creating the block field using Acorn:

$ wp acorn acf:block Example

<?php

namespace App\Blocks;

use Log1x\AcfComposer\Block;
use Log1x\AcfComposer\Builder;

class Example extends Block
{
    /**
     * The block name.
     *
     * @var string
     */
    public $name = 'Example';

    /**
     * The block description.
     *
     * @var string
     */
    public $description = 'Lorem ipsum...';

    /**
     * The block category.
     *
     * @var string
     */
    public $category = 'common';

    /**
     * The block icon.
     *
     * @var string|array
     */
    public $icon = 'star-half';

    /**
     * Data to be passed to the block before rendering.
     *
     * @return array
     */
    public function with()
    {
        return [
            'items' => $this->items(),
        ];
    }

    /**
     * The block field group.
     *
     * @return array
     */
    public function fields()
    {
        $example = Builder::make('example');

        $example
            ->addRepeater('items')
                ->addText('item')
            ->endRepeater();

        return $example->build();
    }

    /**
     * Return the items field.
     *
     * @return array
     */
    public function items()
    {
        return get_field('items') ?: [];
    }
}

You may also pass --construct to the command above to generate a stub with the block properties set within the constructor. This can be useful for localization, etc.

$ wp acorn acf:block Example --construct

When running the block generator, one difference to a generic field is an accompanied View is generated in the resources/views/blocks directory.

@if ($items)
  <ul>
    @foreach ($items as $item)
      <li>{{ $item['item'] }}</li>
    @endforeach
  </ul>
@else
  <p>No items found!</p>
@endif

<div>
  <InnerBlocks />
</div>

Like the field generator, the example block contains a simple list repeater and is working out of the box.

Block Preview View

While $block->preview is an option for conditionally modifying your block when shown in the editor, you may also render your block using a seperate view.

Simply duplicate your existing view prefixing it with preview- (e.g. preview-example.blade.php).

Generating a Widget

Important

With WordPress 5.8, Blocks can now be used as widgets making this feature somewhat deprecated as you would just make a block instead.

If you are on the latest WordPress and would like to use the classic widget functionality from ACF Composer, you will need to opt-out of the widget block editor.

Creating a sidebar widget using ACF Composer is extremely easy. Widgets are automatically loaded and rendered with Blade, as well as registered with WP_Widget which is usually rather annoying.

Start by creating a widget using Acorn:

$ wp acorn acf:widget Example

<?php

namespace App\Widgets;

use Log1x\AcfComposer\Builder;
use Log1x\AcfComposer\Widget;

class Example extends Widget
{
    /**
     * The widget name.
     *
     * @var string
     */
    public $name = 'Example';

    /**
     * The widget description.
     *
     * @var string
     */
    public $description = 'Lorem ipsum...';

    /**
     * Data to be passed to the widget before rendering.
     *
     * @return array
     */
    public function with()
    {
        return [
            'items' => $this->items(),
        ];
    }

    /**
     * The widget title.
     *
     * @return string
     */
    public function title() {
        return get_field('title', $this->widget->id);
    }

    /**
     * The widget field group.
     *
     * @return array
     */
    public function fields()
    {
        $example = Builder::make('example');

        $example
            ->addText('title');

        $example
            ->addRepeater('items')
                ->addText('item')
            ->endRepeater();

        return $example->build();
    }

    /**
     * Return the items field.
     *
     * @return array
     */
    public function items()
    {
        return get_field('items', $this->widget->id) ?: [];
    }
}

Similar to blocks, widgets are also accompanied by a view generated in resources/views/widgets.

@if ($items)
  <ul>
    @foreach ($items as $item)
      <li>{{ $item['item'] }}</li>
    @endforeach
  </ul>
@else
  <p>No items found!</p>
@endif

Out of the box, the Example widget is ready to go and should appear in the backend.

Generating an Options Page

Creating an options page is similar to creating a regular field group in additional to a few configuration options available to customize the page (most of which, are optional.)

Start by creating an option page using Acorn:

$ wp acorn acf:options Example

<?php

namespace App\Options;

use Log1x\AcfComposer\Builder;
use Log1x\AcfComposer\Options as Field;

class Example extends Field
{
    /**
     * The option page menu name.
     *
     * @var string
     */
    public $name = 'Example';

    /**
     * The option page document title.
     *
     * @var string
     */
    public $title = 'Example | Options';

    /**
     * The option page field group.
     *
     * @return array
     */
    public function fields()
    {
        $example = Builder::make('example');

        $example
            ->addRepeater('items')
                ->addText('item')
            ->endRepeater();

        return $example->build();
    }
}

Optionally, you may pass --full to the command above to generate a stub that contains additional configuration examples.

$ wp acorn acf:options Options --full

Once finished, you should see an Options page appear in the backend.

All fields registered will have their location automatically set to this page.

Caching Fields

Each time your application is ran, ACF Composer has to build your field groups into an array to register with ACF. In larger projects, it may be a good idea to cache the field groups into an array during deployment. This can be done using the acf:cache command:

$ wp acorn acf:cache [--status]

Cache can then be cleared using the acf:clear command:

$ wp acorn acf:clear

Custom Stub Generation

To customize the stubs generated by ACF Composer, you can easily publish the stubs directory using Acorn:

$ wp acorn acf:stubs

The publish command generates all available stubs by default. However, each stub file is optional. When a stub file doesn't exist in the stubs/acf-composer directory, the default stub provided by the package will be used.

Default Field Settings

One of my personal favorite features of ACF Composer is the ability to set field type as well as field group defaults. Any globally set default can of course be over-ridden by simply setting it on the individual field.

Global

Taking a look at config/acf.php, you will see a few pre-configured defaults:

'defaults' => [
    'trueFalse' => ['ui' => 1],
    'select' => ['ui' => 1],
],

When setting trueFalse and select to have their ui set to 1 by default, it is no longer necessary to repeatedly set 'ui' => 1 on your fields. This takes effect globally and can be overridden by simply setting a different value on a field.

Field Group

It is also possible to define defaults on individual field groups. This is done by simply defining $defaults in your field class.

/**
 * Default field type settings.
 *
 * @return array
 */
protected $defaults = ['ui' => 0];

My Defaults

Here are a couple defaults I personally use. Any prefixed with acfe_ are related to ACF Extended.

'defaults' => [
    'fieldGroup' => ['instruction_placement' => 'acfe_instructions_tooltip'],
    'repeater' => ['layout' => 'block', 'acfe_repeater_stylised_button' => 1],
    'trueFalse' => ['ui' => 1],
    'select' => ['ui' => 1],
    'postObject' => ['ui' => 1, 'return_format' => 'object'],
    'accordion' => ['multi_expand' => 1],
    'group' => ['layout' => 'table', 'acfe_group_modal' => 1],
    'tab' => ['placement' => 'left'],
    'sidebar_selector' => ['default_value' => 'sidebar-primary', 'allow_null' => 1]
],
