Displaying Content From Custom Post Type with Page Templates

2 Views

So, I’m developing a site for a client where the homepage is built like a one-page scroller, but I also need the functionality of additional pages outside of the single homepage. I’ve built a custom post type for these sections and used this code to display them on the homepage. 

<?php query_posts( array('post_type'=>'homepage', 'posts_per_page' => 1000, 'orderby' => 'menu_order', 'order' => 'ASC') ); ?>
<?php if(have_posts()): while(have_posts()): the_post(); ?>

    <?php 
        global $post;
        $slug = $post->post_name;
        locate_template(
            array(
                "template-$slug.php",
                'template-main.php'
            ), true
        );
    ?>
<?php endwhile; endif; ?>

So, as you can see, this is automatically pulling content and displaying it using page templates based on the post slug, however, I need to allow my client to display the content based on a page template chosen in a dropdown and I’ve used this code to create a dropdown UI that displays the page templates.

add_action( 'add_meta_boxes', 'add_custom_page_attributes_meta_box' );
function add_custom_page_attributes_meta_box(){
global $post;
    if ( 'page' != $post->post_type && post_type_supports($post->post_type, 'page-attributes') ) {
        add_meta_box( 'custompageparentdiv', __('Template'), 'custom_page_attributes_meta_box', NULL, 'side', 'core');
    }
}

function custom_page_attributes_meta_box($post) {
    $template = get_post_meta( $post->ID, '_wp_page_template', 1 ); ?>
    <select name="page_template" id="page_template">
        <?php $default_title = apply_filters( 'default_page_template_title',  __( 'Default Template' ), 'meta-box' ); ?>
        <option value="default"><?php echo esc_html( $default_title ); ?></option>
        <?php page_template_dropdown($template); ?>
    </select><?php
}

add_action( 'save_post', 'save_custom_page_attributes_meta_box' );
function save_custom_page_attributes_meta_box( $post_id ) {
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;
    if ( isset( $_POST['post_type'] ) && 'page' == $_POST['post_type'] ) return;
    if ( ! current_user_can( 'edit_post', $post_id ) ) return;
    if ( ! empty( $_POST['page_template'] ) && get_post_type( $post_id ) != 'page' ) {
        update_post_meta( $post_id, '_wp_page_template', $_POST['page_template'] );
    }
}

So, the problem I’m facing now is how to display all the custom posts in my main page according to the chosen page template.

Thanks so much!

  1. WordPress actually only uses _wp_page_template meta field for page type posts. If you want to change the template, you can use the filter single template. One thing I would recommend is you place good notes that you are using this in your theme/ plugin….

    btw update cpt to your post-type 

    function load_cpt_template($single_template) {
     global $post;

     if ($post->post_type == 'cpt') {

          $new_template = get_post_meta( $post->ID, '_wp_page_template', true ); 

          // if a blank field or not valid do nothing, load default..
          if( is_file($new_template) )
            $single_template = $new_template;
     }
     return $single_template;
}
add_filter( 'single_template', 'load_cpt_template' );
