我是ACF的新手，到目前为止，我设法添加了一个新的自定义字段，并做到了这一点
访问者可以输入应用程序编号和密码，以获取管理员添加的应用程序状态。
我使用了Repeater，对我来说工作起来感觉更好，只剩下一个问题，get\\u field（）的参数是（field name，post id），在我的例子中，我在上面提到的工作中称它为application\\u id。用户如何通过我将以整数格式分配的应用程序编号进行搜索。到目前为止，我已经做到了这一点（忽略内联css）
<div class="entry-content">
<form method="post">
<label>Enter Application ID:</label>
<input type="text" name="application_id">

</form>
<?php
$application_id = $_POST["application_id"];
$entered_pass = $_POST["application_pass"];
$client_name = get_field("client_name", $application_id);
$program = get_field("program", $application_id);
$password = get_field("password", $application_id);
$application_status = get_field("application_status", $application_id);

好了，我终于读了很多文章，最后我把一切都搞定了。因此，如果其他人陷入同样的情况，现在有一个解决方案。
<article id="" class="page type-page status-publish hentry">

</form>
<?php
$application_id = $_POST["application_id"];
$entered_pass = $_POST["application_pass"];
