[Resolved] Display content in single CPT

[Tom]

This has been pretty stumped, it should be working. I’m on the road until tomorrow so I don’t have a localhost to test with, unfortunately.

One more thing to try before I get back into the office tomorrow to figure out exactly why it’s not working:

add_action( 'generate_after_content', function() {
    if ( is_singular( 'your-post-type-name' ) ) {
        previous_post_link();
        next_post_link();
    }
} );

Let me know if that displays anything at all.

[Eva]

Again…. nothing.
Don’t worry about the time, I am not in a hurry.
I’d rather use WP Show Posts (I also have the PRO version) if I wouldn’t need a filterable portfolio with CPT’s…
Thanks for you patience and support!

[Tom]

No problem – I’ll dig into this ASAP and will let you know what I find out 🙂

[Eva]

Hi Tom, thank you! It would be great if the problem can be solved. Even better if I could use WP Show PostsPRO and have a filterable portfolio… That would be the best 🙂
I know it’s not a feature yet, but maybe it can be done another way?
Thanks,
Eva

So I just built a custom post type and named it project.

I then added this function:

add_action( 'generate_after_content', function() {
    if ( is_singular( 'project' ) ) {
        previous_post_link();
        next_post_link();
    }
} );

And it’s showing the links for me. They need to be styled with CSS, but they’re there.

[Eva]

Yessss! Great, it works!! You’re a genius 🙂
Now, to show categories and tags, I add?

Thanks!!!

[Tom]

Awesome 🙂

Are those taxonomies registered in your custom post type? Or do you have custom taxonomies?

[Eva]

I use custom taxonomies: Projectsoorten and Trefwoorden

Thanks!

[Tom]

So you could try something like this:

add_action( 'generate_after_content', function() {
    if ( is_singular( 'project' ) ) {
        previous_post_link();
        next_post_link();

        $projectsoorten = get_the_term_list( get_the_ID(), 'projectsoorten' );
        $trefwoorden = get_the_term_list( get_the_ID(), 'trefwoorden' );

        if ( $projectsoorten ) {
            echo $projectsoorten;
        }

        if ( $trefwoorden ) {
            echo $trefwoorden;
        }
    }
} );

Obviously, it would need to be styled with CSS.

Unfortunately I got an error… I send you the code for the Projectsoort taxonomy, because I think what I send you was not correct (sorry, ones again 🙂

function your_prefix_register_taxonomy() {

$args = array (
‘label’ => esc_html__( ‘Projectsoorten’, ‘text-domain’ ),
‘labels’ => array(
‘menu_name’ => esc_html__( ‘Projectsoorten’, ‘text-domain’ ),
‘all_items’ => esc_html__( ‘All Projectsoorten’, ‘text-domain’ ),
‘edit_item’ => esc_html__( ‘Edit Projectsoort’, ‘text-domain’ ),
‘view_item’ => esc_html__( ‘View Projectsoort’, ‘text-domain’ ),
‘update_item’ => esc_html__( ‘Update Projectsoort’, ‘text-domain’ ),

‘parent_item_colon’ => esc_html__( ‘Parent Projectsoort:’, ‘text-domain’ ),
‘search_items’ => esc_html__( ‘Search Projectsoorten’, ‘text-domain’ ),
‘popular_items’ => esc_html__( ‘Popular Projectsoorten’, ‘text-domain’ ),
‘separate_items_with_commas’ => esc_html__( ‘Separate Projectsoorten with commas’, ‘text-domain’ ),
‘add_or_remove_items’ => esc_html__( ‘Add or remove Projectsoorten’, ‘text-domain’ ),
‘choose_from_most_used’ => esc_html__( ‘Choose most used Projectsoorten’, ‘text-domain’ ),
‘not_found’ => esc_html__( ‘No Projectsoorten found’, ‘text-domain’ ),
‘name’ => esc_html__( ‘Projectsoorten’, ‘text-domain’ ),
‘singular_name’ => esc_html__( ‘Projectsoort’, ‘text-domain’ ),
),
‘public’ => true,
‘show_ui’ => true,
‘show_in_menu’ => true,
‘show_in_nav_menus’ => true,
‘show_tagcloud’ => true,
‘show_in_quick_edit’ => true,
‘show_admin_column’ => false,
‘show_in_rest’ => false,
‘hierarchical’ => false,
‘query_var’ => true,
‘sort’ => false,
‘rewrite_no_front’ => false,
‘rewrite_hierarchical’ => false,
‘rewrite’ => true,
);

register_taxonomy( ‘projectsoort’, array( ‘project’ ), $args );
}
add_action( ‘init’, ‘your_prefix_register_taxonomy’, 0 );

[Tom]

What was the error?

[Eva]

Sorry, this is the error:

Catchable fatal error: Object of class WP_Error could not be converted to string in /home/alfabetp/test.alfabetprodukties.nl/wp-content/themes/generatepress_child/functions.php on line 22

Hope this is of any use…
Thanks again!!

[Tom]

Are projectsoorten and trefwoorden the correct IDs of the taxonomies? I only guessed based on their names.

[Eva]

I think I the ID’s are projectsoort and Trefwoord, because now I don’t get an error anymore. It all looks quite strange though, and even more when I click to open a similar project…
But I am happy it’s almost resolved now!! Thank you for spending so much time!

[Tom]

They likely need to be styled with CSS to look good. I’m not seeing any of the tags listed on your project pages though?
