Сделал для себя такое решение
<div style="display: block; padding:20px 0px;">
<label for="checkAll_taxonomies" >
<button id="checkAll_taxonomies" type="button" class="button button-primary" onclick="setTrueAllCheckBoxes()">Выбрать все</button>
</label>
<label for="checkAll_taxonomies">
<button id="checkAll_taxonomies" type="button" class="button button-primary" onclick="setFalseAllCheckBoxes()">Снять все</button>
</label>
</div>
function setTrueAllCheckBoxes() {
let checkboxes = document.getElementsByName("tax_input[<?= $tax_name ?>][]");
for (let index = 0; index < checkboxes.length; index++) {
if(checkboxes[index].checked === false) {
checkboxes[index].checked = true;
}
}
}
function setFalseAllCheckBoxes() {
let checkboxes = document.getElementsByName("tax_input[<?= $tax_name ?>][]");
for (let index = 0; index < checkboxes.length; index++) {
if(checkboxes[index].checked === true) {
checkboxes[index].checked = false;
}
}
}
шаблон скопировал из post_categories_meta_box и создал свою функцию в functions и вставил туда код сверху
function get_all_categories_box( $post, $box ) {
$defaults = array( 'taxonomy' => 'category' );
if ( ! isset( $box['args'] ) || ! is_array( $box['args'] ) ) {
$args = array();
} else {
$args = $box['args'];
}
$parsed_args = wp_parse_args( $args, $defaults );
$tax_name = esc_attr( $parsed_args['taxonomy'] );
$taxonomy = get_taxonomy( $parsed_args['taxonomy'] );
// Вкладки категории/часто используемые - tabs

<div id="taxonomy-<?php echo $tax_name; ?>" class="categorydiv">

и добавил имя функции в register_taxonomy в поле meta_box_cb
register_taxonomy(
'hireo_brands',
array(
'hireo_service',
'hireo_shop',
'hireo_technique',
),
array(
'labels' => array(
'name' => 'Бренды',
'singular_name' => 'Бренд',
),
'meta_box_cb' => 'get_all_categories_box',
)
);
