Extended ACF

Register advanced custom fields with object oriented PHP.

Extended ACF provides an object oriented API to register fields, groups and layouts with ACF. If you register fields in your theme, you can safely rely on version control when working with other developers. Oh, and you don't have to worry about unique field keys.

Installation

Require this package, with Composer, in the root directory of your project.

$ composer require wordplate/acf

Download the Advanced Custom Fields Pro plugin and put it in either the plugins or mu-plugins directory. Visit the WordPress dashboard and activate the plugin. Please note that this package supports ACF version 5.6 or later. If you want to install ACF Pro with Composer, please scroll down.

Usage

Use the register_extended_field_group() function to register a new field group in ACF. It uses the register_field_group() function behind the scenes. The difference is that it appends the key value to field groups and fields. Below you'll find an example of a field group.

use WordPlate\Acf\Fields\Image;
use WordPlate\Acf\Fields\Text;
use WordPlate\Acf\Location;

register_extended_field_group([
    'title' => 'About',
    'fields' => [
        Image::make('Image'),
        Text::make('Title'),
    ],
    'location' => [
        Location::if('post_type', 'page')
    ],
]);

Find more examples in the examples directory or visit the official ACF documentation to read more about the field group settings.

Fields

All fields have their responding class except the clone field. All fields must have a label. If no name is given, it will use the label as name in lowercase letters. Furthur down this page you'll find a list of available field types.

use WordPlate\Acf\Fields\Text;

Text::make('Title', 'heading')
    ->instructions('Add the text value')
    ->required();

Setting such as wrapper, append and prepend are supported on most fields but not listed in the documentation below. Visit the official documentation to read more about field settings.

// This field will not be visible, but will end the accordion above.
// Any fields added after this will not be a child to the accordion.

    ->collapsed('name')
    ->buttonLabel('Add employee')
    ->layout('table') // block, row or table
    ->required();

Tab - The tab field is used to group together fields into tabbed sections. Any fields or groups added after a acf_tab will become a child to that tab. Setting 'endpoint' to true on a tab will create a new group of tabs.

use WordPlate\Acf\Fields\Tab;

Tab::make('Tab 1'),
Tab::make('Tab 2'),
Tab::make('Tab 3')
    ->placement('top') // top or left
    ->endpoint(), // This will make a break in the tabs and create a new group of tabs.

Relational Fields

Link - The link field provides a simple way to select or define a link (url, title, target).

use WordPlate\Acf\Fields\Link;

Link::make('Read More Link')
    ->required();

Page Link - The page link field allows the selection of 1 or more posts, pages or custom post types.

use WordPlate\Acf\Fields\PageLink;

PageLink::make('Contact Link')

    ->instructions('Select an animal')
    ->postTypes(['animal'])
    ->allowNull()
    ->allowMultiple()
    ->required();

Relationship - The relationship field creates a very attractive version of the post object field.

use WordPlate\Acf\Fields\Relationship;

Relationship::make('Contacts')
    ->instructions('Add the contacts.')
    ->postTypes(['contact'])
    ->filters([
        'search', 
        'post_type',
        'taxonomy'
    ])
    ->min(3)
    ->max(6)
    ->required();

Taxonomy - The taxonomy field allows the selection of 1 or more taxonomy terms.

use WordPlate\Acf\Fields\Taxonomy;

Taxonomy::make('Cinemas')
    ->instructions('Select one or more cinema terms.')
    ->taxonomy('cinema')
    ->appearance('checkbox') // checkbox, multi_select, radio or select
    ->addTerms() // Allow new terms to be created whilst editing
    ->loadTerms() // Load value from posts terms
    ->saveTerms() // Connect selected terms to the post
    ->returnFormat('id'); // id or object

User - The user field creates a select field for all your users.

use WordPlate\Acf\Fields\User;

User::make('User')
    ->roles([
        'administrator',
        'author'
    ])
    ->returnFormat('object');

// Available roles are administrator, author, subscriber, contributor and editor. Deafult is no filter.

Location

The location class let you write custom location rules without the name, operator and value keys.

use WordPlate\Acf\Location;

Location::if('post_type', 'post')->and('post_type', '!=', 'post');

Conditional Logic

The conditional class help you write conditional logic without knowing the fields key value.

use WordPlate\Acf\ConditionalLogic;
use WordPlate\Acf\Fields\File;
use WordPlate\Acf\Fields\Select;
use WordPlate\Acf\Fields\Url;

Select::make('Type')
    ->choices([
        'document' => 'Document',
        'link' => 'Link to resource',
    ]),
File::make('Document', 'file')
    ->conditionalLogic([
        ConditionalLogic::if('type')->equals('document')
    ]),
Url::make('Link', 'url')
    ->conditionalLogic([
        ConditionalLogic::if('type')->equals('link')
    ]),

Theming

This package provides two helpers to make theming with custom fields much cleaner.

Field

Instead of fetching data with get_field and get_sub_field you can use the field helper function. It works as the get_field function except that it checks if the given field name is a sub field first.

echo field('title');

Note: This will not work if nested fields in a field group share the same name.

Option

Instead of passing the option key to the get_field function we can now use the new option function. It will automagically use the get_field function with the option key.

echo option('github-url');

Custom Fields

If your application use fields which isn't part of ACF, you may extend and create custom helper classes. Lets say you've a field for OpenStreetMap. Create a new class which extends the base WordPlate\Acf\Fields\Field class:

namespace Application\Fields;

use WordPlate\Acf\Fields\Field;
use WordPlate\Acf\Fields\Attributes\Instructions;
use WordPlate\Acf\Fields\Attributes\Required;

class OpenStreetMap extends Field
{
    use Instructions;
    use Required;

    protected $type = 'open_street_map';
}

Notice that we've imported traits which inlcude the required() and instructions() methods. We've also added the $type property in order to let ACF know which field we're working with. You may now add any additional methods to this class which you will need such as latitude(), longitude(), zoom(), etc.

When you're ready you can import use it like any other field included in this package:

use Application\Fields\OpenStreetMap;

OpenStreetMap::make('Map')
  ->latitude(56.474)
  ->longitude(11.863)
  ->zoom(10);

Installing ACF with Composer

If you want to install ACF Pro with Composer you may use the repositories feature. Add the snippet below to your composer.json file. Replace your-acf-key with your ACF Pro key and run composer install. Composer should now install the plugin to the plugins directory.

"repositories": [
    {
        "type": "package",
        "package": {
            "name": "wpackagist-plugin/advanced-custom-fields-pro",
            "type": "wordpress-plugin",
            "version": "5.8.9",
            "dist": {
                "url": "https://connect.advancedcustomfields.com/v2/plugins/download?p=pro&k=your-acf-key&t=5.8.9",
                "type": "zip"
            }
        }
    }
]
