Use null coalescing operator for fallback values

[rain2o]

In cases like this, where you are using the value if it exists, otherwise setting a fallback:

You can use null coalescing to simplify it. This also means you only call the function once.

$logo = get_field( 'logo' ) ?? get_template_directory_uri() . '/assets/src/img/circle-brand.png';
$title = get_field( 'title' ) ?? 'Foothills Church';

Another location you could do this https://github.com/Myzwer/foothillschurch/blob/effc5bbf81497ae99f0561ab7849412fe9272bfd/messages.php#L105

'paged'          => get_query_var( 'paged' ) ?? 1,

Could be reduced to 1 or 3 lines, depending on if you want to break it up.

<h2 class="text-lg font-bold uppercase">
    <?php echo get_field('event_start_time') ?? "TBD"; ?> - <?php echo get_field('event_end_time') ?? "TBD"; ?>
</h2>

Another place you can implement this optimization https://github.com/Myzwer/foothillschurch/blob/eb77c6d3119be03e7efd20408e627b1ab9af7aed/components/blocks/event-type.php#L25

$count    = get_sub_field( "num_events" ) ?? 3;

and here in the same file https://github.com/Myzwer/foothillschurch/blob/eb77c6d3119be03e7efd20408e627b1ab9af7aed/components/blocks/event-type.php#L62

Also here, can simplify a few things with these conditions.

https://github.com/Myzwer/foothillschurch/blob/effc5bbf81497ae99f0561ab7849412fe9272bfd/components/headers/default/_button.php#L35-L46

and

https://github.com/Myzwer/foothillschurch/blob/effc5bbf81497ae99f0561ab7849412fe9272bfd/components/headers/default/_image.php#L38-L49

for example

$link = get_sub_field('button_link') ?? get_sub_field('button_link_file');
// Get tab status
$new_tab = get_sub_field('new_tab');
$attrs = null;
if ($tab == "yes") {
    $attrs = 'target="_blank"';
} elseif ($tab == "cc") {
    $attrs = "data-open-in-church-center-modal='true'";
}
