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。

我浏览了代码，找到了它设置哪些字段是必填和不需要的地方，如下：

//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 plugins/paid-memberships-pro/preheaders/checkout.php 之一中找到

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

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，但我无法真正理解是否可能。

谢谢大家:)

Answer 1

（把这段代码放在你的chid主题function.php文件中）

不是舒尔，但你可以先尝试使用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，希望它会奏效。

我发现了一段完美运行的代码

//make sure address fields are required
function my_pmpro_required_user_fields($fields)
{
    global $bfirstname, $blastname, $baddress1, $bcity, $bstate, $bzipcode, $bcountry, $bphone, $bemail;
    $fields["bfirstname"] = $bfirstname;
    $fields["blastname"] = $blastname;
    $fields["baddress1"] = $baddress1;
    $fields["bcity"] = $bcity;
    $fields["bstate"] = $bstate;
    $fields["bzipcode"] = $bzipcode;
    $fields["bphone"] = $bphone;
    $fields["bemail"] = $bemail;
    $fields["bcountry"] = $bcountry;
    return $fields;
}
add_action("pmpro_required_user_fields", "my_pmpro_required_user_fields");

/*
 * Save billing fields when using PayPal
 */
function my_pmpro_paypalexpress_session_vars() {
    $_SESSION['bfirstname'] = $_REQUEST['bfirstname'];
    $_SESSION['blastname'] = $_REQUEST['blastname'];
    $_SESSION['baddress1'] = $_REQUEST['baddress1'];
    $_SESSION['baddress2'] = $_REQUEST['baddress2'];
    $_SESSION['bcity'] = $_REQUEST['bcity'];
    $_SESSION['bstate'] = $_REQUEST['bstate'];
    $_SESSION['bzipcode'] = $_REQUEST['bzipcode'];
    $_SESSION['bphone'] = $_REQUEST['bphone'];
    $_SESSION['bemail'] = $_REQUEST['bemail'];
    $_SESSION['bcountry'] = $_REQUEST['bcountry'];
}
add_action('pmpro_paypalexpress_session_vars', 'my_pmpro_paypalexpress_session_vars');

//load vars back into $_REQUEST
function my_init() {
if(!empty($_REQUEST['review']) && !empty($_REQUEST['token'])) {
    $_REQUEST['bfirstname'] = $_SESSION['bfirstname'];
    $_REQUEST['blastname'] = $_SESSION['blastname'];
    $_REQUEST['baddress1'] = $_SESSION['baddress1'];
    $_REQUEST['baddress2'] = $_SESSION['baddress2'];
    $_REQUEST['bcity'] = $_SESSION['bcity'];
    $_REQUEST['bstate'] = $_SESSION['bstate'];
    $_REQUEST['bzipcode'] = $_SESSION['bzipcode'];
    $_REQUEST['bphone'] = $_SESSION['bphone'];
    $_REQUEST['bemail'] = $_SESSION['bemail'];
    $_REQUEST['bcountry'] = $_SESSION['bcountry'];
}
}
add_action('init', 'my_init');

如果有人仍然需要这个 - 在这种情况下，最佳做法是使用 pmpro_required_user_fields 或 pmpro_required_billing_fields 过滤器，具体取决于您希望哪些字段是必需的 - 用户或帐单字段。

因此，例如，如果您需要一个帐单电话 (bphone) 字段，则可以这样做：

add_filter( "pmpro_required_billing_fields", 'yourtheme_require_phone' );
function yourtheme_require_phone($pmpro_required_user_fields) {

  global $bphone;

  $pmpro_required_user_fields["bphone"] = $bphone;

  return $pmpro_required_user_fields;
}
