I'm not entirely sure what you're trying to do. 我不确定您要做什么。 But I'm pretty sure you want to set the value of a form field to a value from the URI query string. 但我很确定您要将表单字段的值设置为URI查询字符串中的值。
The way you've done this is correct in the first snippet is correct, but your issue is that you're using POST and not for your form method. 在第一个代码段中，这样做的方法是正确的，但是您的问题是您使用的是POST，而不是表单方法。 Here is how you should do it if you want it for both types. 如果要同时使用两种类型，则应按以下步骤进行操作。
<?php
if ($_POST['id_brg']) {
$id_brg = $_POST['id_brg'];
} else if ($_GET['id_brg']) {
$id_brg = $_GET['id_brg'];
} else {
$id_brg = uniqid();
}
?>
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<form action="two.php" method="POST">
<input type="text" name="id_brg" value="<?php echo $id_brg; ?>">
</form>
</body>
</html>

Consider use POST method on your form. 考虑在表单上使用POST方法。
<input type="text" name="id_brg" value="<?php echo $_POST['id_brg']; ?>">
You miss semicolon on the code you provide below. 您在下面提供的代码上错过了分号。
$_POST['id_brg'];
