问题描述：

I have added CPT UI and Custom Fields plugins to my Wordpress set up. I am trying to add custom posts onto a portfolio page and have two issues that I think must be linked.

Firstly, I cannot get thumbnail images to display on the portfolio page. I have added

\"add_theme_support( \'post-thumbnails\' );\"

to my functions.php file as instructed. The \"add_theme_support( \'menus\' );\" function works fine.

Featured images is enabled and displaying when I add the Portfolio Piece.

In the absence of the image I added a text link which did display but the link address is

\"http://localhost/localwp.dev/2018/07/13/hello-world/\"

and not \"http://localhost/localwp.dev/portfolio_wadn/post/\"

So I know I am missing something because the Portfolio page is not finding the right slug/address to link to the post. I think it must be the way I\'ve set up either the Custom Fields or CPT UI settings but I can\'t find anything that solves the issue.

Can anyone help? Code below.

functions.php code:

<?php 
add_theme_support( \'menus\' );
add_theme_support( \'post-thumbnails\' );
function register_theme_menus () {
register_nav_menus( 
array(
\'primary-menu\'  => __( \'Primary Menu\')
)
);
}
add_action( \'init\', \'register_theme_menus\');
function wadn_theme_styles() {
wp_enqueue_style( \'foundation_css\', get_template_directory_uri() . 
\'/css/foundation.css\' );  
wp_enqueue_style( \'googlefont_css\', \'http://fonts.googleapis.com/css? 
family=Asap:400,700,400italic,700italic\' );
wp_enqueue_style( \'main_css\', get_template_directory_uri() . \'/style.css\' );
}
add_action( \'wp_enqueue_scripts\', \'wadn_theme_styles\' );
function wadn_theme_js() {
wp_enqueue_script( \'modernizr_js\', get_template_directory_uri() . \'/js/modernizr.js\', \'\',  \'\', false );
wp_enqueue_script( \'foundation_js\', get_template_directory_uri() . \'/js/foundation.min.js\', array(\'jquery\'), \'\', true );
wp_enqueue_script( \'app_js\', get_template_directory_uri() . \'/js/app.js\', array(\'jquery\', \'foundation_js\'), \'\', true );  
}
add_action( \'wp_enqueue_scripts\', \'wadn_theme_js\' );
?>

page-portfolio.php code:

<?php 
/* 
Template Name: Portfolio Page 
*/
?>
<?php get_header(); ?>
<section class=\"row\">
<div class=\"small-12 columns text-center\">
<div class=\"leader\">
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<h1><?php the_title(); ?></h1>
<?php the_content(); ?>
<?php endwhile; endif; ?>
</div>
</div>
</section>
<?php 
$args = array(
\'post-type\' => \'portfolio_wadn\'
);
$query = new WP_Query ( $args );
?>
<section class=\"row no-max pad\">
<?php if( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post(); ?>
<div class=\"small-6 medium-4 large-3 columns grid-item\">
<a href=\"<?php the_permalink(); ?>\">Test</a>
</div>    
<?php endwhile; endif; wp_reset_postdata(); ?>
</section>
<?php get_footer(); ?>
