如何在沒有 PHP 輸入標簽的情況下通過 POST 將值發送到另一個頁面？我嘗試過這種方式，但也沒有用。<?phpinclude("database/config.php");include("database/opendb.php");include("functions.php");if (isset($_POST["totalHobbies"])) {    $par = $_POST["totalHobbies"];}$query = "SELECT firstname, lastname, hobbies, id ";$query .= "FROM persons ";$query .= "WHERE hobbies = ? ";$preparendquery = $dbaselink->prepare($query);$preparendquery->bind_param("i", $par);$preparendquery->execute();if ($preparendquery->errno) {    echo "Fout bij uitvoeren commando". "<br>";} else {    $result = $preparendquery->get_result();    if ($result->num_rows === 0) {        echo "Geen rijen gevoenden" . "<br>" ;    } else {        while ($row = $result->fetch_assoc()) {    // here is the problem            echo "<form action=\"details.php\" method='POST' >";    //refer to details.php page            $id = $row["id"];            echo "<a href=\"details.php?id= " . $row['id'] . " \">" . fullname($row['firstname'], $row['lastname']). "</a>". "<br>";            echo "<input type=\"hidden\" name = \"id\" value= '$id'> </input>";            echo "</form>";        };    }}$preparendquery->close();echo"<br><button onclick=\"location.href='index.html'\">Back</button>";include("database/closedb.php");?>
