I'm trying to get a custom endpoint in a plugin, I'm replicating a logic from another plugin to achieve this. But I got stuck in the important part that is getting de JSON.

First I created the Big List of Metaboxes:

<?php
class MenuPageMetabox {

public function initialize() 
{
    add_filter('rwmb_meta_boxes', array($this, 'menus_metaboxes'));
}

function menus_metaboxes($meta_boxes__menus)
{
    $prefix = '_menus_pcc_';

    $pp_dy = 'desayunos';
    $pp_bb = 'bebidas';
    $pp_en = 'entradas';
    $pp_sp = 'sopas';
    $pp_dc = 'dulces';
    $pp_sl = 'saludables';
    $pp_ft = 'fuertes';
    $pp_ts = 'tacos';
    $pp_sh = 'sandwiches_hamburguesas';

    $icon_dy = _ASSETS. 'assets/Iconos-01.png';
    $icon_bb = _ASSETS. 'assets/Iconos-06.png';
    $icon_en = _ASSETS. 'assets/Iconos-02.png';
    $icon_sp = _ASSETS. 'assets/Iconos-03.png';
    $icon_dc = _ASSETS. 'assets/Iconos-04.png';
    $icon_sl = _ASSETS. 'assets/Iconos-05.png';
    $icon_ft = _ASSETS. 'assets/Iconos-07.png';
    $icon_ts = _ASSETS. 'assets/Iconos-09.png';
    $icon_sh = _ASSETS. 'assets/Iconos-08.png';

    $placehodler = _ASSETS. 'assets/placeholder.png';

$meta_boxes__menus[] = array(
    'title'     => 'Secciones de Menú',
    'id'    => $prefix . 'secciones_menu', 
    'post_types' => 'page',
    'context' => 'advanced',
    'include' => array(
        'template'        => array( 'page-menu.php' ),
    ),
    'tabs'      => array(
        $pp_dy => array(
            'label' => 'Desayunos',
            'icon'  => $icon_dy,
        ),
        $pp_en  => array(
            'label' => 'Las Entradas',
            'icon'  => $icon_en,
        ),
        $pp_bb  => array(
            'label' => 'Las Bebidas',
            'icon'  => $icon_bb,
        ),
        $pp_sp  => array(
            'label' => 'Las Sopas',
            'icon'  => $icon_sp,
        ),
        $pp_dc  => array(
            'label' => 'Lo Dulce',
            'icon'  => $icon_dc,
        ),
        $pp_sl  => array(
            'label' => 'Lo Saludable',
            'icon'  => $icon_sl,
        ),
        $pp_ft  => array(

            )
        )
    )
);

    return $meta_boxes__menus;
}

}

then creating the endpoints:

require_once(CLASSES . 'class-repository.php');

class Play_Enpoints_Menus {
    public function init() {
        $this->register('/menus/', array('\API\Play_Repository_Menus', 'get_menus'));
    }

public function register($path, $callback, $method = 'GET', $namespace = 'api/v1') {
    add_action('rest_api_init', function() use ($path, $callback, $method, $namespace) {
        register_rest_route($namespace, $path, array(
            'methods' => $method,
            'callback' => $callback
        ));
    });
}
}

<?php
namespace API;
use WP_Query;
use stdClass;
use RW_Meta_Box;
use RWMB_Image_Field;

class Play_Repository_Menus 
{

public static function get_menus()
{
    $prefix = 'pinno_menus_pcc_';

    $pp_dy = $prefix.'desayunos';
    $pp_bb = $prefix.'bebidas';
    $pp_en = $prefix.'entradas';
    $pp_sp = $prefix.'sopas';
    $pp_dc = $prefix.'dulces';
    $pp_sl = $prefix.'saludables';
    $pp_ft = $prefix.'fuertes';
    $pp_ts = $prefix.'tacos';
    $pp_sh = $prefix.'sandwiches_hamburguesas';   

    $mb_menu = '';

    $pp_dy_ep = rwmb_meta($pp_dy);

    if(!empty(self::$pp_dy_ep)) {
        foreach ( self::$pp_dy_ep as self::$ppdyep ) {
            $mb_menu .= isset( self::$ppdyep[$prefix . 'npn'. $pp_dy] ) ? self::$ppdyep[$prefix . 'npn'. $pp_dy] : '';
        }
    }

    return $mb_menu;
}

}

But the Metabox come with an empty string.

I know totally that I'm not understanding at all the logic of how can I create my own custom endpoint.

But I feel that is about the ID of The page.

by the way, my plugin is creating the MB and creates a Custom Page Also.

Hope someone can help me .

Hi,

The variable $prefix in the function menus_metaboxes() has value _menus_pcc_ while it has value pinno_menus_pcc_ in the function get_menus(). Could you please check it again?

Got it!

check this out:
https://pastebin.com/MR0mGF5q

The only thing now I'm trying is to validate if the endpoint coexists in a page_template, but that doesn't seem to work:

...
        $menu_list = array();
        $menu_list["MenuList"] = $mb_menu;
        $not_available = array();
        $not_available["Status"] = 'Endpoint not available';

if(get_page_template('page-menu.php')) {
                return $menu_list;
} else {
   return $not_available;
}

I don't know if I need to use all the PathURL for the get_template_path or is no logic to call that function for the endpoint (that I feel that is the right answer, lol).

In another case which validation you recommend guys?

Thank you

Hi,

The function get_template_path() returns the path of page template in current or parent template. If you want to check the specific template, please try to use the function is_page_template(). For more information, please follow these documentations
