Advanced Custom Field Development

ACFD is a Wordpress plugin that uses Advanced Custom Field core in order to register custom fields via PHP in a easier way.

Why use ACFD?

ACF saves all custom field data into database, that is the slowest and heaviest way to use ACF

ACF suggests you to register your fields via PHP (read this article), but the exported PHP code is very long and difficult to read

ACFD allow you to save some rows of code

How ACFD work?

You can add ACFD code in yout theme's function.php

First of all you must check if ACFD is active

if ( class_exists( 'ACFD' ) && ACFD::isActive() ) {
	...
}

Than you can create your first custom group

$group = new CustomGroup('mygroup', 'options_page == acf-options');

The second argument of CustomGroup is the location Using location like 'options_page == acf-options' creates options pages automatically

Now you can create your custom fields

$field = $group->addField('myfield1', 'Field #1', 'text');

If you want to change custom field's attributes use the 'set' function

$field->set('placeholder', 'Insert your informations');

You can also use the short form

$group->addField('myfield1', 'Field #1', 'text')
	  ->set('placeholder', 'Insert your informations');

In order to use the repeater-type custom field you can use the 'addContainer' function

$repeater = $group->addContainer('myrepeater', 'List', 'repeater');
$repeater->addField('item1', 'Item', 'text');

Your final code:

if ( class_exists( 'ACFD' ) && ACFD::is_active() ) {
	
	$group = new CustomGroup('mygroup', 'options_page == acf-options');

	$group->addField('myfield1', 'Field #1', 'text')
		  ->set('placeholder', 'Insert your informations');
	
	$repeater = $group->addContainer('myrepeater', 'List', 'repeater');
	$repeater->addField('item1', 'Item', 'text');
    
}
