在Wordpress上发布保存后更改重定向URL

Question

我有一个问题，希望这里有一些好人可以帮助我。我准备了一个前端表格。这是一个捐赠表格，我已经在表格提交后添加了一个cURL电话到支付网关api。这里的问题是，我希望表单页面重定向到支付网关api返回的URL，以便用户通过他们的银行，异地付款。

我的想法是在帖子保存后更改帖子固定链接，但在用户被重定向之前，以便将它们重定向到正确的URL（由支付网关api给出），而不是原始永久链接。

有没有想过执行这个？

到目前为止，这是我的代码：

<?php

add_action('acf/save_post', 'my_save_post', 10, 1);

function my_save_post( $post_id ) {

$billplzApi = get_field('billplz_secret_key', 'option');
$billplzId = get_field('billplz_collection_id', 'option');

// bail early if not a donation post
if( get_post_type($post_id) !== 'donation' ) {
    return;
}
// bail early if editing in admin
if( is_admin() ) {  
    return;
}

$post = get_post( $post_id);

$amount = '';
$donationGroup = get_field('donation_amount', $post);
$selectedAmount = $donationGroup['select_donation_amount'];
$customAmount = $donationGroup['specify_any_amount'];

if(!$customAmount){
    $amount = $selectedAmount;
} else {
    $amount = $customAmount;
}

$name = get_field('name', $post);
$email = get_field('email', $post);
$unmobile = get_field('mobile', $post);
$mobile = "+6" . $unmobile;


$billplz_data = array(
      'amount' => $amount * 100,
      'name' => $name,
      'mobile' => $mobile,
      'email' => $email,
      'collection_id' => $billplzId,
      'deliver' => false,
      'description' => 'a test for payment gateway',
      'redirect_url' => home_url('donation-redirect'),
      'callback_url' => home_url('donation-callback')
    );

      $process = curl_init('https://www.billplz.com/api/v3/bills/');
      curl_setopt($process, CURLOPT_HEADER, 0);
      curl_setopt($process, CURLOPT_USERPWD, $billplzApi . ":");
      curl_setopt($process, CURLOPT_TIMEOUT, 30);
      curl_setopt($process, CURLOPT_RETURNTRANSFER, TRUE);
      curl_setopt($process, CURLOPT_POSTFIELDS,http_build_query($billplz_data));
      $return = curl_exec($process);
      curl_close($process);
      $arr = json_decode($return, true);
      //this is the url to replace the original post permalink
      $billplz_url = $arr['url'];       

}

acf_form_head();
get_header();
?>

<div class="row">
    <div class="col-sm-12 col-md-8 col-md-offset-2 col-xs-12">

<?php 

while (have_posts()) : the_post();

acf_form(array(
    'post_id'       => 'new_post',
    'new_post'      => array(
                        'post_type'     => 'donation',
                        'post_status'   => 'publish'


    ),
    'submit_value'  => 'Donate',
    'html_submit_button' => '<input type="submit" class="acf-button btn btn-success btn-lg pull-right" value="%s" />',
    'return' => '%post_url%'
));

endwhile;

?>

    </div>
</div>

<?php 

get_footer();

?>

在这里找到了解决这个问题的方法：Create WordPress Page that redirects to another URL

所以基本上我需要添加：

header('Location:'.$billplz_url);
exit();

并删除：

'return' => '%post_url%'
