wpcf7_special_mail_tags がフックしてくれない。

Question

WordPressのContact Form 7のwpcf7_special_mail_tagsを利用して
total、product01_count、product02_count、product03_countの4つを追加しています。

function my_special_mail_tags($output, $name, $html){

    if ('total' == $name) {
        $submission = WPCF7_Submission::get_instance();
        $data = $submission -> get_posted_data();
        $count1_1 = $data['your-product01-count1'];
        $count1_2 = $data['your-product01-count2'];
        $count1_3 = $data['your-product01-count3'];
        $count1 = $count1_1 + $count1_2 + $count1_3;
        $count2_1 = $data['your-product02-count1'];
        $count2_2 = $data['your-product02-count2'];
        $count2_3 = $data['your-product02-count3'];
        $count2 = $count2_1 + $count2_2 + $count2_3;
        $count3_1 = $data['your-product03-count1'];
        $count3_2 = $data['your-product03-count2'];
        $count3_3 = $data['your-product03-count3'];
        $count3 = $count3_1 + $count3_2 + $count3_3;
        $ret = number_format($count1*25000 + $count2*18300 + $count3*15500);
        return $ret;
    }

    if ('product01_count' == $name) {
        $submission = WPCF7_Submission::get_instance();
        $data = $submission -> get_posted_data();
        $count1 = $data['your-product01-count1'];
        $count2 = $data['your-product01-count2'];
        $count3 = $data['your-product01-count3'];
        $ret = $count1 + $count2 + $count3;
        return $ret;
    }

    if ('product02_count' == $name) {
        $submission = WPCF7_Submission::get_instance();
        $data = $submission -> get_posted_data();
        $count1 = $data['your-product02-count1'];
        $count2 = $data['your-product02-count2'];
        $count3 = $data['your-product02-count3'];
        $ret = $count1 + $count2 + $count3;
        return $ret;
    }

    if ('product03_count' == $name) {
        $submission = WPCF7_Submission::get_instance();
        $data = $submission -> get_posted_data();
        $count1 = $data['your-product03-count1'];
        $count2 = $data['your-product03-count2'];
        $count3 = $data['your-product03-count3'];
        $ret = $count1 + $count2 + $count3;
        return $ret;
    }

}

add_filter('wpcf7_special_mail_tags', 'my_special_mail_tags', 10, 3);

これによって、商品の注文個数と金額を計算しています。
個数が1個以上ある場合には、きちんとフックしてくれるのですが、個数が0個の場合にはなぜかフックせずにタグがそのまま表示されてしまいます。

0個の場合にもきちんとフックさせるにはどのような方法が必要でしょうか？

マルチポストは非推奨なのですね。失礼しました。急いでいたもので、WPのコミュニティとこちらと両方に投稿させていただきました。

ひとまず正しい方法かどうかはわからないのですが、以下の方法で解決しました。
wpcf7_before_send_mail　を使って、送信前の書き換えられていないタグを0で置換することによって処理しました。
ありがとうございました。

function my_wpcf7_before_send_mail($cf7)
{
    $mail = $cf7->prop('mail');
    $mail['body'] = str_replace("[total]", "0", $mail['body']);
    $mail['body'] = str_replace("[product01_count]", "0", $mail['body']);
    $mail['body'] = str_replace("[product02_count]", "0", $mail['body']);
    $mail['body'] = str_replace("[product03_count]", "0", $mail['body']);

    $mail2 = $cf7->prop('mail_2');
    $mail2['body'] = str_replace("[total]", "0", $mail2['body']);
    $mail2['body'] = str_replace("[product01_count]", "0", $mail2['body']);
    $mail2['body'] = str_replace("[product02_count]", "0", $mail2['body']);
    $mail2['body'] = str_replace("[product03_count]", "0", $mail2['body']);

    $cf7->set_properties(array("mail" => $mail,"mail_2" => $mail2));
    return $cf7;
}

add_action('wpcf7_before_send_mail', 'my_wpcf7_before_send_mail', 1, 1)

私の方は私の方でミスがあって、結局うまく対応できていなかったので、修正しました。
最終的な形は以下です。

function my_wpcf7_before_send_mail($cf7)
{
$submission = WPCF7_Submission::get_instance();
$data = $submission->get_posted_data();
$count1_1 = isset($data['your-product01-count1']) ? $data['your-product01-count1'] : 0;
$count1_2 = isset($data['your-product01-count2']) ? $data['your-product01-count2'] : 0;
$count1_3 = isset($data['your-product01-count3']) ? $data['your-product01-count3'] : 0;
$count1 = $count1_1 + $count1_2 + $count1_3;
$count2_1 = isset($data['your-product02-count1']) ? $data['your-product02-count1'] : 0;
$count2_2 = isset($data['your-product02-count2']) ? $data['your-product02-count2'] : 0;
$count2_3 = isset($data['your-product02-count3']) ? $data['your-product02-count3'] : 0;
$count2 = $count2_1 + $count2_2 + $count2_3;
$count3_1 = isset($data['your-product03-count1']) ? $data['your-product03-count1'] : 0;
$count3_2 = isset($data['your-product03-count2']) ? $data['your-product03-count2'] : 0;
$count3_3 = isset($data['your-product03-count3']) ? $data['your-product03-count3'] : 0;
$count3 = $count3_1 + $count3_2 + $count3_3;
$replace0 = number_format($count1 * 25000 + $count2 * 18300 + $count3 * 15500);

$count1 = isset($data['your-product01-count1']) ? $data['your-product01-count1'] : 0;
$count2 = isset($data['your-product01-count2']) ? $data['your-product01-count2'] : 0;
$count3 = isset($data['your-product01-count3']) ? $data['your-product01-count3'] : 0;
$replace1 = $count1 + $count2 + $count3;

$count1 = isset($data['your-product01-count1']) ? $data['your-product02-count1'] : 0;
$count2 = isset($data['your-product01-count2']) ? $data['your-product02-count2'] : 0;
$count3 = isset($data['your-product01-count3']) ? $data['your-product02-count3'] : 0;
$replace2 = $count1 + $count2 + $count3;

$count1 = isset($data['your-product01-count1']) ? $data['your-product03-count1'] : 0;
$count2 = isset($data['your-product01-count2']) ? $data['your-product03-count2'] : 0;
$count3 = isset($data['your-product01-count3']) ? $data['your-product03-count3'] : 0;
$replace3 = $count1 + $count2 + $count3;

$mail = $cf7->prop('mail');
$mail['body'] = str_replace("[total]", $replace0, $mail['body']);
$mail['body'] = str_replace("[product01_count]", $replace1, $mail['body']);
$mail['body'] = str_replace("[product02_count]", $replace2, $mail['body']);
$mail['body'] = str_replace("[product03_count]", $replace3, $mail['body']);

$mail2 = $cf7->prop('mail_2');
$mail2['body'] = str_replace("[total]", $replace0, $mail2['body']);
$mail2['body'] = str_replace("[product01_count]", $replace1, $mail2['body']);
$mail2['body'] = str_replace("[product02_count]", $replace2, $mail2['body']);
$mail2['body'] = str_replace("[product03_count]", $replace3, $mail2['body']);

$cf7->set_properties(array("mail" => $mail, "mail_2" => $mail2));
return $cf7;
}

add_action('wpcf7_before_send_mail', 'my_wpcf7_before_send_mail', 1, 1);

結局タグ追加は行わず、フォームに入力されたデータをWPCF7_Submissionで取得して、my_wpcf7_before_send_mailでメール本文から追加タグ部分を置換するという形式で処理しました。
こちらはうまく動きましたので共有させていただきます。

よろしくお願いいたします。
