I have custom posts types for Recipes, and within that I have set up Advanced Custom Fields (from the plugin.)

Within, that custom post type, I have several categories. Two questions:

1.) How do I get all posts from a custom category? I get how to display the custom fields, but not sure how to call all the posts from a custom category, then I can display it's title, image, and link.

2.) In a custom post type scenario am I better off setting up custom categories as well or use the generic post categories?

I've tried the get_posts, then tried by getting posts by custom category. for example

<?php
$args = array(
     'posts_per_page' => 8,
     'orderby' => 'rand',
     'post_type' => 'recipes',
     'type' => 'side-dishes',
     'post_status' => 'publish'
);
$show_albums = get_posts( $args );
?>

I don't know the exact implementation, since post_type is a custom post, and figure I would have to do some for-each probably to then use the_field (from ACF)

=========================================================== Ok after taking suggestion below here is what I have please let me know if I am doing this correct?

here is the query - which seems to work:

<?php

// The Query
$the_query = new WP_Query($args = array(
    'post_type' => 'recipes',
    'custom_cat' => 'side-dishes'
) );

// The Loop
if ( $the_query->have_posts() ) {
        echo '<ul>';
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        echo '<li>' . get_the_title() . '</li>';
    }
        echo '</ul>';
} else {
    // no posts found
}
/* Restore original Post Data */
wp_reset_postdata();?>

I registered the taxonomy, but what's confusing me is that, my registered post-type is recipes, shouldn't register_taxonomy be "recipes" and not 'custom_cat?"

register_taxonomy( 'custom_cat', 
        array('recipes'), /* if you change the name of register_post_type( 'custom_type', then you have to change this */
        array('hierarchical' => true,     /* if this is true, it acts like categories */
            'labels' => array(
                'name' => __( 'Recipe Categories', 'bonestheme' ), /* name of the custom taxonomy */
                'singular_name' => __( 'Recipe Category', 'bonestheme' ), /* single taxonomy name */
                'search_items' =>  __( 'Search Recipe Categories', 'bonestheme' ), /* search title for taxomony */
                'all_items' => __( 'All Recipe Categories', 'bonestheme' ), /* all title for taxonomies */
                'parent_item' => __( 'Parent Recipe Category', 'bonestheme' ), /* parent title for taxonomy */
                'parent_item_colon' => __( 'Parent Custom Category:', 'bonestheme' ), /* parent taxonomy title */
                'edit_item' => __( 'Edit Custom Category', 'bonestheme' ), /* edit custom taxonomy title */
                'update_item' => __( 'Update Custom Category', 'bonestheme' ), /* update title for taxonomy */
                'add_new_item' => __( 'Add New Custom Category', 'bonestheme' ), /* add new title for taxonomy */
                'new_item_name' => __( 'New Custom Category Name', 'bonestheme' ) /* name title for taxonomy */
            ),
            'show_admin_column' => true, 
            'show_ui' => true,
            'query_var' => true,
            'rewrite' => array( 'slug' => 'custom-slug' ),
        )
    );

here is the registered post type:

function create_recipe() { 
    // creating (registering) the custom type 
    register_post_type( 'recipes', /* (http://codex.wordpress.org/Function_Reference/register_post_type) */
        // let's now add all the options for this post type
        array( 'labels' => array(
            'name' => __( 'Recipes', 'bonestheme' ), /* This is the Title of the Group */
            'singular_name' => __( 'Recipe', 'bonestheme' ), /* This is the individual type */
            'all_items' => __( 'All Recipes', 'bonestheme' ), /* the all items menu item */
            'add_new' => __( 'Add New Recipe', 'bonestheme' ), /* The add new menu item */
            'add_new_item' => __( 'Add Recipe', 'bonestheme' ), /* Add New Display Title */
            'edit' => __( 'Edit', 'bonestheme' ), /* Edit Dialog */
            'edit_item' => __( 'Edit Recipe', 'bonestheme' ), /* Edit Display Title */
            'new_item' => __( 'New Recipe Type', 'bonestheme' ), /* New Display Title */

            'not_found_in_trash' => __( 'Nothing found in Trash', 'bonestheme' ), /* This displays if there is nothing in the trash */
            'parent_item_colon' => ''
            ), /* end of arrays */
            'description' => __( "Recipes section for It's Just food", 'bonestheme' ), /* Custom Type Description */
            'public' => true,
            'publicly_queryable' => true,
            'exclude_from_search' => false,
            'show_ui' => true,
            'query_var' => true,

            'menu_icon' => get_stylesheet_directory_uri() . '/library/images/custom-post-icon.png', /* the icon for the custom post type menu */
            'rewrite'   => array( 'slug' => 'recipes', 'with_front' => false ), /* you can specify its url slug */

            'capability_type' => 'post',
            'hierarchical' => false,
            /* the next one is important, it tells what's enabled in the post editor */

        ) /* end of options */
    ); /* end of register post type */

What have you tried? Have you done any research? Have you looked into using WP_Query? –  Howdy_McGee Feb 25 at 20:24
    
yeah, that's fair, will ammend my question to add what I tried. –  user31344 Feb 25 at 20:28

This might be a good read for you. I'm not sure exactly what you're looking to do so I'll lay this out in a simple format.

This query will pull all Posts under the Post Type recipes where the custom field side-dishes exists. You can then loop through and display them how you would like.

$recipes = new WP_Query(
    array(
        'post_type' => 'recipes',
        'posts_per_page' => 8,
        'orderby' => 'rand',
        'post_status' => 'publish',
        'meta_query' => array(
            array(
                'key' => 'side-dishes'
                'compare' => 'EXISTS'
            )
        )
    )
);

This 2nd query will pull all posts under the taxonomy my_taxonomy_name_here which you will need to replace with your taxonomy. It looks for categories with the slug my_category_slug_here which you will need to replace with the category slug. You can replace 'slug' with ID and pull it based off that if you'd like.

$recipes = new WP_Query(
    array(
        'post_type' => 'recipes',
        'posts_per_page' => 8,
        'orderby' => 'rand',
        'post_status' => 'publish',
        'tax_query' => array(
            array(
                'taxonomy' => 'my_taxonomy_name_here',
                'field' => 'slug',
                'terms' => 'my_category_slug_here'
            )
        )
    )
);

You can then loop through each post like a normal loop:

<?php if($recipes->have_posts()) : ?>
    <?php while($recipes->have_posts()) : $recipes->the_post(); ?>
        <h1><?php the_title(); ?></h1>
        <?php the_content(); ?>
    <?php endwhile; ?>
<?php endif; wp_reset_query(); ?>

in the template for this page am already calling in posts using <?php if (have_posts()) : while (have_posts()) : the_post(); ?> , would the wp_query be unnecessary? –  user31344 Feb 25 at 22:14
    
WP_Query is a standard way to show multiple post types on the same page. The Loop you posted is the main loop for that specific post type. You can modify the main loop using the pre_get_posts filter if you'd like. –  Howdy_McGee Feb 25 at 22:23
    
ok so it's ok to have two wp_querys on the same page as long as they don't interfere with each other? –  user31344 Feb 25 at 22:56
    
here is what I am working with now: <?php // The Query $the_query = new WP_Query($args = array( 'post_type' => 'recipes', 'recipe' => 'side-dishes' ) ); // The Loop if ( $the_query->have_posts() ) { echo '<ul>'; while ( $the_query->have_posts() ) { $the_query->the_post(); echo '<li>' . get_the_title() . '</li>'; } echo '</ul>'; } else { // no posts found } /* Restore original Post Data */ wp_reset_postdata();?> –  user31344 Feb 25 at 22:59

yeah, it worked, just wanted to check if there was any problems with the solution. It might work, but then down the line.. at any rate I very much appreciate your time! –  user31344 Feb 26 at 16:43
