Question

我有我的代码，提交后应该在其中显示成功消息（单击添加），但是由于某种原因，即使没有添加任何内容，此成功消息也会一直显示，它只是显示在问题是如果我删除了if语句下面的消息，该消息将不会显示。动作正常，这只是成功的消息。您能看看有什么问题吗？

Answer 1

我尝试了一下，发现您需要开始会话

您只需要添加session_start();

<?php
    session_start();
    if(isset($_REQUEST['submit_btn']))
    {
       $name = $_POST["names"];
       $_SESSION['add'] = $name;
       print_r($_SESSION);
    }
?>
<html>
  <head>

  </head>
  <body>
    <?php
      if(isset($_SESSION['add'])) {
    ?>
        <div class="">
            <strong>Success!</strong> News added successfully..
        </div>
    <?php
        }
    ?>
    <form action="" method="POST">
       <input type="text" name="names" id="names">
       <input type="submit" value="submit" name="submit_btn">
    </form>
    <script>

    </script>
  </body>
</html>

Answer 2

问题似乎出在if(isset($_SESSION['add']))行。因此，只要设置了$_SESSION['add']，您就必须看到该消息。您可以在消息后立即将其取消设置，然后在每次单击按钮时将其重置，或者如果您单击的按钮名为“提交”，则只需使用

if(isset($_POST['add'])){
   //output message here
}

Answer 3

我以您的代码为例，删除验证和其他内容

我还将Add.php重定向到processToAdd.php，然后再次将processToAdd.php重定向到Add.php

请看看并尝试一下。

希望这可以解决您的问题。

Add.php ：

$_GET['param1']

processToAdd.php ：

<?php
  session_start();
?>
<!-- Content Wrapper. Contains page content -->
<div class="content-wrapper">
  <!-- Content Header (Page header) -->
  <section class="content-header">
    <h1>
      Add Coming Soon Movie
    </h1>
    <?php
      if(isset($_SESSION['add'])) {
    ?>
      <div class="alert alert-success">
        <strong>Success!</strong> News added successfully..
      </div>
    <?php
      }
    ?>

    </section>

    <!-- Main content -->
    <section class="content">

      <!-- Default box -->
      <div class="box">
        <div class="box-body">
            <form action="processToAdd.php" method="post" enctype="" id="form1">
              <div class="form-group">
                <label class="control-label">Movie name</label>
                <input type="text" name="name" class="form-control"/>

              </div>

              <div class="form-group">
                <button class="btn btn-success" type="submit">Add Movie</button>
              </div>
        </form>
        </div>
        <!-- /.box-footer-->
