Rendering ACF Content Blocks in WordPress.

ACF (Advanced Custom Fields) is a popular plugin for adding custom fields to WordPress. Sometimes, you may encounter an issue where the ACF content blocks are not rendering properly on your website. This can happen due to various reasons, such as incorrect field settings or conflicts with other plugins or themes.

To troubleshoot and resolve this issue, you can follow these steps:

  1. Verify ACF Field Settings: Ensure that the ACF fields are correctly set up with the appropriate field types and settings. Double-check the field names and make sure they match the field names used in your code.

  2. Check Field Group Placement: Confirm that the ACF field group is assigned to the correct location. You can do this by going to the “Edit” screen of the post type or page where you want the ACF content to appear and checking the “Location” rules of the field group.

  3. Check Template File: Make sure that you are using the correct template file for the post type or page where the ACF content should be displayed. Check if the template file is properly calling the ACF fields using the get_field() function.

Here’s an example code snippet that demonstrates how to retrieve and display ACF content using the get_field() function:

<?php
// Get the ACF field value
$custom_content = get_field('custom_content');

// Display the ACF content
echo $custom_content;
?>

In the above example, the get_field() function is used to retrieve the value of the “custom_content” field. The retrieved value is then echoed to display the ACF content on the website.

  1. Disable Conflicting Plugins/Themes: Temporarily deactivate other plugins or switch to a default WordPress theme to check if there are any conflicts causing the ACF content blocks not to render. If the ACF content appears after deactivating a specific plugin or theme, you can investigate further to resolve the conflict.

  2. Check for PHP Errors: Enable debugging in WordPress to check if there are any PHP errors that might be preventing the ACF content from rendering. You can do this by adding the following code to your wp-config.php file:


define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);


By following these steps, you should be able to troubleshoot and resolve the issue of ACF content blocks not rendering on your WordPress website.

Examples

Example 1: Troubleshooting ACF Content Blocks not Rendering


This example demonstrates how to troubleshoot and fix the issue of ACF (Advanced Custom Fields) content blocks not rendering on a WordPress website.


<?php
function wpsnippets_acf_content_blocks_not_rendering() {
    if( function_exists('acf_register_block') ) {
        add_filter('acf/settings/remove_wp_meta_box', '__return_false');
    }
}
add_action('init', 'wpsnippets_acf_content_blocks_not_rendering');


In this code example, we use the acf_register_block function to check if ACF is enabled on the website. If it is, we use the add_filter function to prevent the removal of the ACF meta box in the WordPress editor.


Example 2: Enabling ACF Content Blocks for Specific Post Types


This example demonstrates how to enable ACF content blocks for specific post types on a WordPress website.


<?php
function wpsnippets_enable_acf_content_blocks_for_post_types() {
    if( function_exists('acf_register_block') ) {
        acf_register_block(array(
            'name' => 'custom_block',
            'title' => __('Custom Block'),
            'description' => __('A custom block for specific post types.'),
            'render_callback' => 'wpsnippets_render_custom_block',
            'category' => 'common',
            'icon' => 'admin-comments',
            'keywords' => array('custom', 'block', 'post type'),
            'post_types' => array('post', 'page'),
        ));
    }
}
add_action('acf/init', 'wpsnippets_enable_acf_content_blocks_for_post_types');

function wpsnippets_render_custom_block($block) {
    // Render block content here
}


In this code example, we use the acf_register_block function to register a custom ACF content block. We specify the block name, title, description, render callback function, category, icon, keywords, and the post types where the block should be available. The wpsnippets_render_custom_block function is the callback function responsible for rendering the block content.


Example 3: Customizing ACF Content Block Output


This example demonstrates how to customize the output of an ACF content block on a WordPress website.


<?php
function wpsnippets_customize_acf_content_block_output($block, $content) {
    if ($block['name'] === 'custom_block') {
        $custom_content = '<div class="custom-block">' . $content . '</div>';
        return $custom_content;
    }
    return $content;
}
add_filter('render_block', 'wpsnippets_customize_acf_content_block_output', 10, 2);


In this code example, we use the render_block filter to customize the output of an ACF content block. We check if the block name matches our custom block, and if it does, we wrap the block content in a <div> element with a custom CSS class. The modified content is then returned.
