这是我的 php 处理页面
<?php include '../../functions/process-database.php'; print_r($_POST); if (isset($_POST['submit']) && $_POST['submit'] == "Add Activitie") { echo "works"; $title = $_POST['title']; $description = $_POST['description']; $date = $_POST['date']; $category_id = $_POST['category_id']; $status = $_POST['status']; if (! empty ( $_FILES )) { $image = time () . "-" . basename ( $_FILES ['img'] ['name'] ); move_uploaded_file ( $_FILES ['img'] ['tmp_name'], "../../images/activities/$image" ); } else { echo "Error: No Image Selected"; exit (); } $query = "INSERT INTO `activitie`(`title`, `description`, `date`, `image`, `category_id`, `status`) VALUES ('$title','$description','$date','$image','$category_id','$status')"; $result = mysqli_query ( $conn, $query ); print_r($_POST);exit; if ($result) { header('Location: ../display-activitie.php'); } else { die ( mysqli_error () ); } }

<input type="submit" name="submit" value="Add Activitie" class="submit">
自
<input type = "hidden" name = "submit" value = "Add Activitie"/>
<input type = "submit" value = "Add Activitie" class = "submit">
