ACF 5 compatibility

I have ACF 5 loaded and this plugin is not working. Looking forward to seeing an update soon.

Thanks!

I had this same problem last night so I attempted to create a ACF v5 PRO port. This worked for me but there is probably a better way — *use at your own risk*

Based on the Creating A New Field Type I needed 2 things to make this work. In (#1) fz-acf-nav-menu.php, register v5 support in via (#2) nav-menu-v5.php.

#1
Register v5 port in /plugins/advanced-custom-fields-nav-menu-field/fz-acf-nav-menu.php

<?php
/*
Plugin Name: Advanced Custom Fields: Nav Menu Field

class acf_field_nav_menu_plugin
{
	function __construct()
	{
		// version 4+
		add_action('acf/register_fields', array($this, 'register_fields'));	

		// version 5+
		add_action('acf/include_field_types', array($this, 'include_field_types'));
	}

	function register_fields()
	{
		include_once('nav-menu-v4.php');
	}

	function include_field_types()
	{
		include_once('nav-menu-v5.php');
	}
}
new acf_field_nav_menu_plugin();

#2
Create the v5 file at /plugins/advanced-custom-fields-nav-menu-field/nav-menu-v5.php and use the following:

<?php

class acf_field_nav_menu_v5 extends acf_field
{
	var $settings, $defaults;
	function __construct()
	{
		$this->name = 'nav_menu';
		$this->label = __('Nav Menu', 'acf');
		$this->category = __("Relational",'acf'); // Basic, Content, Choice, etc
		$this->defaults = array(
			'save_format' => 'id',
			'allow_null' => 0,
			'container' => 'div'
		);
    	parent::__construct();
		$this->settings = array(
			'path' => apply_filters('acf/helpers/get_path', __FILE__),
			'dir' => apply_filters('acf/helpers/get_dir', __FILE__),
			'version' => '1.1.2'
		);
	} 

	function render_field_settings( $field )
	{
		$field = array_merge($this->defaults, $field);
		$key = $field['name']; 

		// Create Field Options HTML
		acf_render_field_setting( $field, array(
			'label'			=> __('Return Value','acf'),
			'type'		=>	'radio',
			'name'		=>	'fields['.$key.'][save_format]',
			'value'		=>	$field['save_format'],

		$choices = $this->get_allowed_nav_container_tags();
		acf_render_field_setting( $field, array(

			'instructions'	=> __('What to wrap the Menu\'s ul with.<br />Only used when returning HTML.','acf'),
			'type'		=>	'select',
			'name'		=>	'fields['.$key.'][container]',

			'choices' 	=>	$choices
		)); 

		acf_render_field_setting( $field, array(

	}

	function render_field( $field )
	{
		// create Field HTML
		echo sprintf( '<select id="%d" class="%s" name="%s">', $field['id'], $field['class'], $field['name']  );

		if( $field['allow_null'] )
		{
			echo '<option value=""> - Select - </option>';
		}

		// Nav Menus
		$nav_menus = $this->get_nav_menus();

		foreach( $nav_menus as $nav_menu_id => $nav_menu_name ) {
			$selected = selected( $field['value'], $nav_menu_id );
			echo sprintf( '<option value="%1$d" %3$s>%2$s</option>', $nav_menu_id, $nav_menu_name, $selected );
		}

		echo '</select>';
	}

	function get_nav_menus() {
		$navs = get_terms('nav_menu', array( 'hide_empty' => false ) );

		$nav_menus = array();
		foreach( $navs as $nav ) {
			$nav_menus[ $nav->term_id ] = $nav->name;
		}

		return $nav_menus;
	}

	function get_allowed_nav_container_tags() {
		$tags = apply_filters( 'wp_nav_menu_container_allowedtags', array( 'div', 'nav' ) );
		$formatted_tags = array(
			array( '0' => 'None' )
		);
		foreach( $tags as $tag ) {
    		$formatted_tags[0][$tag] = ucfirst( $tag );
		}
		return $formatted_tags;
	}

	function format_value_for_api( $value, $post_id, $field )
	{
		$field = array_merge($this->defaults, $field);

		if( !$value ) {
			return false;
		}

		// check format
		if( $field['save_format'] == 'object' ) {
			$wp_menu_object = wp_get_nav_menu_object( $value );

			if( !$wp_menu_object ) {
				return false;
			}

			$menu_object = new stdClass;

			$menu_object->ID = $wp_menu_object->term_id;
			$menu_object->name = $wp_menu_object->name;
			$menu_object->slug = $wp_menu_object->slug;
			$menu_object->count = $wp_menu_object->count;

			return $menu_object;

		} elseif( $field['save_format'] == 'menu' ) {
			ob_start();
			wp_nav_menu( array(
				'menu' => $value,
				'container' => $field['container']
			) );
			return ob_get_clean();
		}
		return $value;
	}
}

// create field
new acf_field_nav_menu_v5();

And that should be it.

(Optional) I was able to get the values back out by using:

<?php

$post_id = 259; // your post id here
$acf_field_id = 'sidebar_menu'; // your acf field id here

$field = get_field($acf_field_id, $post_id);
if($field){
	$items = wp_get_nav_menu_items($field );
	if($items){
		// view menu as json
		// echo json_encode($items);

		// OR grab all the titles
		$titles = array();
		foreach($items as $key => $value){
			$titles[] = $value ->title;
		}
		print_r($titles);
	}
}

Hope this helps someone,
Enjoy!

Hi,
I also am having issues and the plugin is not working with the acf 5 version.
Will there be a plugin release to have it work with version 5?

Much appreciated,

Dan

We installed it on the website and it worked perfectly.

Time to roll it out across all sites, along with ACF v5 🙂

Thanks,

Andi

Awesomepants. Stellar work with this plugin. Thanks man!
