This guide (generated by ChatGPT) explains how to automatically switch between two Bricks Builder Single Post templates depending on a post’s publish date.
For example:
- Posts before September 16, 2025 → Template A
- Posts on/after September 16, 2025 → Template B
Prerequisites
- Bricks Builder is installed and active
- Two Single templates created in Bricks:
- Template 1 (for older posts)
- Template 2 (for newer posts)
- Access to your theme’s functions.php file or an MU-plugin
Grabbing the Template IDs
The easiest way to get the template ID is to look in the shortcodes field within Bricks > Templates.

Code Snippet
Add the following code to your theme’s functions.php file, wpCodeBox, or to a custom plugin:
<?php
/**
* Switch Bricks Single templates based on publish date.
*
* Template IDs:
* - 142628 → Newer posts (on/after cutoff date)
* - 143702 → Older posts (before cutoff date)
*
* Cutoff date: September 16, 2025
*/
add_filter('bricks/active_templates', 'fw_switch_template_by_publish_date', 10, 3);
function fw_switch_template_by_publish_date($active_templates, $post_id, $content_type) {
// Only affect single content templates
if ($content_type !== 'content') {
return $active_templates;
}
// Limit to standard posts only
if (get_post_type($post_id) !== 'post') {
return $active_templates;
}
// Template IDs
$TEMPLATE_AFTER = 142628; // for posts ON/AFTER the cutoff
$TEMPLATE_BEFORE = 143702; // for posts BEFORE the cutoff
// Cutoff date (YYYY-MM-DD format)
$cutoff_ts = strtotime('2025-09-16 00:00:00 UTC');
// Get publish date (UTC timestamp)
$published_ts = get_post_time('U', true, $post_id);
// Decide which template to use
$active_templates['content'] = ($published_ts >= $cutoff_ts)
? $TEMPLATE_AFTER
: $TEMPLATE_BEFORE;
return $active_templates;
}
