Displaying Custom Post Content In Wordpress Pages And Theme Templates

The Problem: Restricted Content Display Options

The default WordPress loop allows you to display post and page content easily, but custom post types require additional code to output their content outside of standard templates and queries. This poses a problem for developers and site builders aiming to incorporate non-standard content, like custom post types, across their WordPress site.

By default, pages and posts leverage the main query and loop to automatically display their contents. The main loop runs on category, author, date, post type, and search archives as well as the home page. However, custom post types are excluded from this main query.

Therefore, displaying custom post entries in things like page templates and sidebar widgets requires executing custom WordPress queries before outputting the post data. Understanding this distinction enables you to properly display varied content types beyond the post and page defaults.

Table of Contents

Solution Overview: Using Custom Queries and Functions

Displaying custom post content across your WordPress site involves getting familiar with the difference between standard post queries versus more customized alternatives. Additionally, leveraging key WordPress functions like WP_Query() and get_posts() allow for flexible content fetching.

By combining custom queries with associated display functions, you can craft reusable code for outputting custom post entries, fields, and data on templates, pages, and widgets across a WordPress site. When paired with a well-structured custom post type, the possibilities become endless.

Understanding Standard vs. Custom Queries

The main WordPress query executes automatically to retrieve posts and pages to display within the various default template files. The parameters for this query are set by WordPress to determine the content for the current page based on URL factors and more.

Alternatively, custom WordPress queries allow you to manually define custom parameters like post type, taxonomy terms, date ranges, custom fields, and more. This equates to more control and flexibility regarding what content gets fetched and displayed.

Key WordPress Functions

WP_Query() and get_posts() are two key functions for running custom queries. WP_Query() offers advanced capabilities for filtering queried data while get_posts() provides a simpler, more direct query method. Both return content in a format you can loop through and display via your chosen code method.

Understanding these key differences allows you to leverage the best function based on your specific needs and content output requirements.

Fetching Custom Post Content

Fetching custom post type content requires a custom query targeted at retrieving your specific non-standard content models. For example:

$args = array(
  'post_type' => 'custom_content',
  'posts_per_page' => 10 
);

$custom_query = new WP_Query( $args );

This query specifically targets the custom_content post type, limiting results to 10 posts per page. The returned $custom_query variable can then be looped through to display the post data.

WP_Query vs. get_posts

WP_Query enables advanced querying and content filtering using a robust set of parameters. But get_posts provides a simpler, more direct way to retrieve targeted post content. Choosing the best approach depends on project needs.

For example, WP_Query would allow querying by custom taxonomy terms or custom date ranges more easily. But get_posts requires fewer resources so could be better for simple content retrieval.

Customizing Fetch Parameters

Custom post queries allow filtering on things like:

Post type – Target specific custom post types
Number of posts – Limit total posts fetched
Offset – Skip over a defined number of posts
Order & Orderby – Control display order
Date range – Filter by published date

Fine-tuning these parameters lets you better filter and target the exact custom post content you aim to display.

Displaying Custom Post Content

Once fetched from the database using a custom query, displaying custom post entries involves looping through the results and outputting the associated content using HTML markup, PHP tags, and other elements.

For example, you could add the following within a page template file after defining your custom query:

<div class="custom-post-content">

  <?php if ( $custom_query->have_posts() ) : ?>

    <?php while ( $custom_query->have_posts() ) : $custom_query->the_post(); ?>
      
      <h3><?php the_title(); ?></h3>
      
      <div class="post-content">
        <?php the_content(); ?>
      </div>

    <?php endwhile; ?>

  <?php endif; ?>
  
  <?php wp_reset_postdata(); ?>
  
</div>

This loops through each post fetched, outputting the title and content. The associated CSS helps visually style the displayed content.

Formatting Considerations

When displaying custom post data, additional formatting can enhance readability. For example, leveraging:

HTML headings and semantic markup for structure
Paragraph and BR tags to space out content
Unordered or Ordered lists when displaying content excerpts

Formatted output helps inform the visitor and improves overall site presentation.

Integrating Custom Content into Pages

To integrate custom post listings and content into WordPress pages, using a custom page template code is the most effective approach. First, create a new Template Name file like page-templates/custom-posts.php. Next, build out the template file with code to execute your custom query and display the post data.

For example:

<?php
/*
* Template Name: Custom Post Display
*/

get_header(); ?>

<main>

  <?php 
    $args = array(
      'post_type' => 'custom_type',
      'posts_per_page' => 5
    );
    
    $custom_query = new WP_Query( $args );
  ?>

  <?-- Rest of custom post display loop -->

</main>

<?php get_footer(); ?>

Then under Page Attributes when editing a page, you can select this new template file to leverage its custom post output.

Passing Attributes

For greater control you could pass attributes through the page URL allowing visitors to dictate aspects like filters, order, categories and more. For example:

www.your-site.com/display-posts?post_type=custom&filter=abc

Then retrieve these attribute values to build conditional queries and content.

Embedding Custom Posts into Theme Templates

In addition to page templates, custom functions help centralize post display code for reuse across theme template files. First, register a function:

function display_custom_posts() {

  $args = array(
    'post_type' => 'custom',
    'posts_per_page' => 10
  );

  $custom_query = new WP_Query( $args );

  // Loop for output  
}

Then call this function anywhere needed, like templates for:

index.php
sidebar.php
custom-post-archive.php
single-custom-post.php

Centralizing display logic into reusable functions keeps code clean and consistent across templates.

Template Setup

Template files should be structured like so:

Open PHP tags
Define custom query
Execute function call
Close PHP tags

This allows keeping all related logic together for easy future editing.

Registering Custom Post Types

Use a plugin or functions.php to register custom types. Consider things like:

Post type name
Label plurals and singular
Supported features like title, editor, comments, etc.
Has archive page?
Custom taxonomy associations

Properly registering the custom type makes querying and displaying it much easier.

Additional Tips and Tricks

Here are some other tips for working with custom post types and queries in WordPress:

Troubleshooting Content Display

If facing issues displaying content, check things like:

Typos in custom post type names
Query variables match registered names
Proper file paths to custom template files
Permissions allow reading template and function files

Double check all text string matches the associated registration names.

Query and Formatting Optimization

To optimize performance:

Limit unnecessary queries inside loops
Set hard query limits for post counts
Reuse queries instead of redefining
Compress HTML output when possible
Add caching for expensive queries

Simple optimizations like caching make a difference.
