Question

以下代码是我的评论表。我在我的博客文章中包含了这个文件comments.php。当用户点击提交时，他们会被带到博客页面，而不是保留在他们正在查看的博客文章页面上。

我在整个网站中对不同的表单使用了相同的代码，这些页面不会重定向，而是在用户点击提交时保留在同一页面上。这是正确的方式。

我想知道为什么当用户点击提交时，博客页面上的相同代码会被重定向到博客类别视图。

如何防止重定向谢谢。

    <?php
    // define variables and set to empty values
    $nameErr = $emailErr = $commentErr = "";
    $name = $email = $comment = "";

    if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (empty($_POST["name"])) {
    $nameErr = "First Name is required";
    } else {
    $name = test_input($_POST["name"]);
    // check if name only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
      $nameErr = "Only letters and white space allowed"; 
    }
    }


    //email

    if (empty($_POST["email"])) {
    $emailErr = "Email is required";
    } else {
    $email = test_input($_POST["email"]);
    // check if e-mail address is well-formed
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
      $emailErr = "Invalid email format";

Answer 1

我使用iframe作为此问题的解决方案而不是php include。谢谢你的帮助

Answer 2

在表单中传递一个隐藏字段

＆LT;输入类型=＆＃34;隐藏＆＃34;值=＆＃34; testRedirect＆＃34;＆GT;

并将重定向代码放在您重定向的位置

如果（isset（$ _ REQUEST [＆＃34;隐藏＆＃34;]））

{

标题（＆＃39;位置：http://www.example.com/your_form_view_page＆＃39;）;

出口;

}

当用户单击表单上的提交时，将用户保持在同一页面上
