Question

我正在尝试使用php的$ _POST功能或$ _SESSION功能来获取基于前一页面的表单数据的数组。每当我尝试使用$ _SESSION时，我都会收到错误：“脚本试图执行方法或访问不完整对象的属性。”这是我想要做的事情的想法。任何帮助都会很棒，并提前感谢！

     <?php

    // initialize a session
    include 'hoteldetails.php';
    session_start();

作为起点，您需要打开和关闭php标签：

<?PHP
    session_start();
?>
    <html>
        <head>

        </head>
        <body>

<?PHP
$colors=array();
array_push($colors, "green");
array_push($colors, "white");
array_push($colors, "yellow");
array_push($colors, "black");

$_SESSION['color']=$colors;
?>

        <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
            <input type="submit" name="Search" value="Search">
        </form>

<?php
if(isset($_POST['Search'])){
header("Location: page2.php");
}

?>

使用带有SESSION或POST的数组
