How to wrap hardcoded array in PHP? - php

Question

I want to separate some part of my arrays so I can make the details dynamic and different in my WordPress website.
I'm using ACF to get my custom post type taxonomy and trying to generate some attributes and make them tabs using the acf_add_local_field_group function but unfortunately am not able to make it work.
The reason why I want to separate the array is because am not able to call global $post; and I have a function which is a meta box for that to retrieve the taxonomy terms.
Here is my code:
function my_acf_add_local_field_groups()
{
acf_add_local_field_group(array(
'key' => 'tab_group_1',
'title' => 'Product Sizes and Prices',
'name' => 'group_sizes_tab',
'fields' => array(
array(
'key' => 'field_tab_size_1',
'label' => 'First Size',
'name' => 'store_sizes_',
'type' => 'tab',
'parent' => 'tab_group_1',
'instructions' => '',
'required' => 0,
'conditional_logic' => 0,
'wrapper' => array(
'width' => '',
'class' => '',
'id' => '',
) ,
'collapsed' => '',
'min' => '',
'max' => '',
) ,
array(
'key' => 'field_unique_key',
'label' => 'Simple Repeater',
'name' => 'simple_repeater',
'type' => 'repeater',
'instructions' => '',
'required' => 0,
'conditional_logic' => 0,
'wrapper' => array(
'width' => '',
'class' => '',
'id' => '',
) ,
'collapsed' => '',
'min' => 0,
'max' => 10,
'layout' => 'table',
'button_label' => 'Add row',
'sub_fields' => array(
array(
'key' => 'field_unique_key_1',
'label' => 'Total Products',
'name' => 'total_products',
'type' => 'text',
) ,
array(
'key' => 'field_unique_key_2',
'label' => 'Total Prices',
'name' => 'total_prices',
'type' => 'text',
) ,
) ,
) ,
array(
'key' => 'field_tab_size_2',
'label' => 'Second Size',
'name' => 'store_sizes_2',
'type' => 'tab',
'parent' => 'tab_group_1',
'instructions' => '',
'required' => 0,
'conditional_logic' => 0,
'wrapper' => array(
'width' => '',
'class' => '',
'id' => '',
) ,
'collapsed' => '',
'min' => '',
'max' => '',
) ,
) ,
'location' => array(
array(
array(
'param' => 'post_type',
'operator' => '==',
'value' => 'products',
) ,
) ,
) ,
));
}
add_action('acf/init', 'my_acf_add_local_field_groups');
As you can see in the group_sizes_tab the fields value is the one I want to separate. Am thinking storing it in a variable but when I tested it it doesn't work.
Just to make it short, basically outside the function it'll be like this:
$fields = array(
'key' => 'field_tab_size_1',
'label' => 'First Size',
'name' => 'store_sizes_',
'type' => 'tab',
'parent' => 'tab_group_1',
'instructions' => '',
'required' => 0,
'conditional_logic' => 0,
'wrapper' => array(
'width' => '',
'class' => '',
'id' => '',
) ,
'collapsed' => '',
'min' => '',
'max' => '',
);
Then I replace this value inside the function but it is not working.
How can I wrap the array and replace it with a variable in the function?
