php - Wordpress - 编辑插件的过滤器功能

Question

我想知道是否有人可以帮助我。

我有一个名为 Paid Memberships Pro 的插件。

在注册表单上有一些我想必填的字段。

我查看了代码，找到了设置哪些字段是必填字段和哪些字段不是必填字段的地方，如下所示:

//require fields
$pmpro_required_billing_fields = array(
    "bfirstname" => $bfirstname,
    "blastname" => $blastname,
    "baddress1" => $baddress1,
    "bcity" => $bcity,
    "bstate" => $bstate,
    "bzipcode" => $bzipcode,
    "bphone" => $bphone,
    "bcountry" => $bcountry,
    "bemail" => $bemail,
    "CardType" => $CardType,
    "AccountNumber" => $AccountNumber,
    "ExpirationMonth" => $ExpirationMonth,
    "ExpirationYear" => $ExpirationYear,
    "CVV" => $CVV
);
$pmpro_required_billing_fields = apply_filters("pmpro_required_billing_fields", $pmpro_required_billing_fields);
$pmpro_required_user_fields = array(
    "username" => $username,
    "password" => $password,
    "password2" => $password2,
    "bemail" => $bemail,
    "bconfirmemail" => $bconfirmemail
);
$pmpro_required_user_fields = apply_filters("pmpro_required_user_fields", $pmpro_required_user_fields);

这可以在插件核心文件之一 plugins/paid-memberships-pro/preheaders/checkout.php 中找到

我希望能够覆盖它，但我不想编辑核心文件，有没有办法通过我的主题 functions.php 文件编辑它？

例如，将 bfirstname 和 blastname 添加到 $pmpro_required_user_fields?

任何帮助将不胜感激，我一直在寻找如何做到这一点，但我真的无法理解它是否可能。

谢谢大家:)

(将此代码放入您的 chid 主题 function.php 文件中)

不确定，但您可以先尝试使用 remove_filters:

remove_filters("pmpro_required_billing_fields", $pmpro_required_billing_fields);
remove_filters("pmpro_required_billing_fields", $pmpro_required_user_fields);

然后您可以克隆这些数组，自定义它们(并稍微更改它们的名称)，然后为自定义数组重新应用过滤器:

$pmpro_required_billing_fields2 = array(
    /* your custom code goes here */
);
$pmpro_required_billing_fields2 = apply_filters("pmpro_required_billing_fields", $pmpro_required_billing_fields2);

$pmpro_required_user_fields2 = array(
    /* your custom code goes here */
);
$pmpro_required_user_fields2 = apply_filters("pmpro_required_user_fields", $pmpro_required_user_fields2);

这只是一个未经测试的想法，希望它能奏效。
