自定义和添加woocommerce模板数据

Question

I am having some trouble customizing the woocommerce templates in my wordpress theme. I would like to add additional data as variables in my templates.

I want to show active orders on the dashboard/my-account page. I want to do this by passing in order data variables to the template to be able to call, like how it is done in the orders.php template.

I know I can override the wc-template-functions.php in my theme and then add the data in the wc_get_templates function for the dashboard or my account. However, I don't want to do this.

What I've tried is creating a hook such as:

functions.php

function wc_fr_add_orders_to_account( $fr_account_orders, $current_page ) {
  global $fr_account_orders;
  $current_page = empty( $current_page ) ? 1 : absint( $current_page );

  $customer_orders = wc_get_orders( apply_filters( 'woocommerce_my_account_my_orders_query', 
    array( 
      'customer' => get_current_user_id(), 
      'page' => $current_page, 
      'paginate' => true,
      'status' => array( 'wc-pending' )
      ) ) );

  $fr_account_orders = array(
    'current_page' => absint( $current_page ),
    'customer_orders' => $customer_orders,
    'has_orders' => 0 < $customer_orders->total
  );

  return $fr_account_orders;
}
add_action( 'woocommerce_account_content', 'wc_fr_add_orders_to_account' );

/theme-directory/woocommerce/templates/myaccount/dashboard.php (also tried in my-account.php)

do_action( 'woocommerce_account_dashboard', $fr_account_orders);
var_dump($fr_account_orders);

$fr_account_orders comes back null. However if I var_dump the array in the hook function, it comes back with data. Any help is appreciated.

Eaasy there. If you want to return the variable, that's just not the way to do it. You should use the apply_filters like so:

function wc_fr_add_orders_to_account() {
    /* your function */

    return $fr_account_orders;
}
add_filter( 'woocommerce_account_dashboard', 'wc_fr_add_orders_to_account' );

and in your template..

$my_var = apply_filters( 'woocommerce_account_dashboard', $fr_account_orders );
var_dump( $my_var );

now if you want to send some variables do it like so:

function wc_fr_add_orders_to_account( $var1, $var2 ) {
    /* your function */

    return $fr_account_orders;
}
add_filter( 'woocommerce_account_dashboard', 'wc_fr_add_orders_to_account', 10, 3 );

and in your template again..

$my_var = apply_filters( 'woocommerce_account_dashboard', $fr_account_orders, $var1, $var2 );
var_dump( $my_var );

read more about apply_filters here https://developer.wordpress.org/reference/functions/apply_filters/ one more thing, try not to change templates, but use add_action on the do_action hooks from template for better compatibility. thanks!
