In the Bricks forum, a user asks:
Hi there, I am setting up an events calendar using bricks.
In some circumstances I would like to display the date of the event as just ‘21 Dec’ and in other places with the year too and maybe written day i.e. ‘Friday 21 Dec 2022’ .
I have created a custom field with acf for the date and it works great in my repeater on the front end, but how can I change the output of the date on a case by case basis?
Simplified I’d like to do something like {acf_date:d j}
This Pro tutorial shows how we can define a custom function and use that with the Dynamic data feature of Bricks to output any Advanced Custom Fields‘ Date-type of field in the specified format.

Step 1
Edit the Date Picker-type of field in your field group.
Set Return Format to Ymd.
Save changes.
Step 2
Add the following in child theme‘s functions.php (w/o the opening PHP tag) or a code snippets plugin:
// Function to return the given ACF date field in the specified format
function bl_get_acf_date( $field, $format = 'F j, Y' ) {
$date_string = get_post_meta( get_the_ID(), $field, true );
if ( $date_string ) {
// Create DateTime object from value (formats must match).
$date = DateTime::createFromFormat( 'Ymd', $date_string );
return $date->format( $format );
}
return '';
}
Set your desired default date format in
$format = 'F j, Y'
Step 3
To output a date field in the default format set in the function above:
{echo:bl_get_acf_date(banner_start)}
where banner_start is the name of the custom field.
Sample output: December 14, 2022
Another example:
{echo:bl_get_acf_date(banner_start, Y-m-d)}
outputs 2022-12-14.
Another example:
{echo:bl_get_acf_date(banner_start, l j M Y)}
outputs Wednesday 14 Dec 2022.
