ACF Helper

A composer package for programmatically adding ACF fields to your Wordpress site.

Why use this package?

Elliott Condon's Advanced Custom Fields is an amazing plugin for enhancing the content on a Wordpress site. However, programmatically adding fields is a cumbersome process, requiring writing multiple nested arrays, or creating the field group first in the plugin itself then exporting the code (with the end result still being a huge web of arrays).

This package aims to reduce the amount of field boilerplate diluting your theme's code by simplifying the process of registering field groups and fields programmatically.

Requirements

• Composer
• Advanced Custom Fields Wordpress plugin
• Advanced Custom Fields Pro or the Field Type addon plugins if you plan to use premium field types.

Installation

You can use Composer to add the package to your project by using composer require fryiee/acf-repeater:0.1.* or adding fryiee/acf-repeater:0.1.* directly to the composer.json.

Add the package to your functions.php or similar theme file (such as a TimberSite class file) by adding use Fryiee\ACF\Helper as ACFHelper to the top of the file.

Basic Example

$fieldGroup = ACFHelper::createFieldGroup('Example Field Group', '_a_suffix_to_the_group_key');
$fieldGroup->addLocation('post_type', '==', 'post');
$field = ACFHelper::createField('text', 'Example Field', ['required' => 1], '_a_suffix_to_the_field_key');
$fieldGroup->addField($field);
ACFHelper::enqueue($fieldGroup);

Classes & Methods

Helper

The \Fryiee\ACF\Helper package is the main entry point of the Helper package. This is where you will generate all your field groups and fields, as well as enqueue them.

Helper::createFieldGroup($title, $keySuffix = '', $args = []);

This static method creates an instance of \Fryiee\ACF\FieldGroup. It takes the title of the Field Group as an argument, optionally a key suffix, and optionally additional arguments. By default, the helper class will set the field group's key to group_slugified_title, with the key suffix being added if it is not empty.

The $args argument takes any of the existing arguments for fields. See here: https://www.advancedcustomfields.com/resources/register-fields-via-php/

REMINDER: Changing your field group's title or key suffix will mean that existing data is no longer connected unless it is altered in the database.

Helper::createField($type, $label, $args, $keySuffix = '')

This static method creates an instance of \Fryiee\ACF\Field. It takes the type of the field, the label, any additional arguments as an array, and optionally a key suffix. By default, the helper class will set the field's name to the slug of the label, and set the key to field_slugified_label, with the key suffix being added if it is not empty. This can be overrided by providing a 'name' attribute in the $args array.
