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 () );
    }

}

Answer 1

改变：

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

到

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

如何在$ _POST方法中解决提交值为空？
