我在带有模式页面的第一页上具有搜索框$_POST['search']。在模式页面上，我能够显示该搜索框中的值。但是，当我单击“提交”按钮以在第二页上发布时，搜索框变量返回一个空值。请帮助我。
这是我的html代码
<?php
session_start();
$globalpid = $_POST['search'];
$_SESSION['search'] = "$globalpid";
?>
<?php
require_once 'config.php';
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title></title>
<meta name="description" content="Hello World">

<input type="submit" name="submit" value="Search" style=" margin-top: 5px; width: 150px;" class="btn btn-info" />
</div>
</form>
</div>
<?php
if (empty($_POST['search']))
{
?>
<div class="panel-footer">
<?php echo "There was no search results!"; } ?>
</div>
</div>
</div>
最佳答案
确保您的表单action =“首页的网址”。我认为您没有将$ _POST ['search']分配给$ globalpid。在首页尝试以下代码：
第一页
<?php
session_start();
if(isset($_POST['search'])){
$globalpid = $_POST['search'];
$_SESSION['search'] = "$globalpid";
}
?>
第二页
<?php
session_start();
//print_r($_SESSION);
if(isset($_SESSION['search'])){
$globalpid = $_SESSION['search'];
echo $globalpid;
}
