Question

我正在为类赋值构建一个族树，我必须根据要更新的信息将变量从HTML表单传递给该系列成员的PHP文件。我需要表单变量才能传递给父亲，母亲，妻子等的php文件。

HTML文件

<form action="handle_family.php" method="post">
<p>Family Member: <select name="name">
<option value="david">David</option>
<option value="linda">Linda</option>
<option value="cayla">Cayla</option>
<option value="sophie">Sophie</option>
<option value="sawyer">Sawyer</option>

<p>History: <input type="text" name="history" size="60" /></p>
<p>Occupation: <input type="text" name="occupation" size="60" /></p>

<input type="submit" name="submit" value="Update Page" />

<?php // Script 6.2 - handle_reg.php

$okay= TRUE;
$relationship= $_POST['relationship'];
$interests= $_POST['interests'];
$history= $_POST['history'];
$occupation= $_POST['occupation'];
$name= $_POST['name'];

if($name == 'david')
{
session_start();
$_SESSION[$father_relationship] = $relationship;
$_SESSION[$father_interests] = $interests;
$_SESSION[$father_occupation] = $occupation;
$_SESSION[$father_name] = $name;
$_SESSION[$father_history] = $history;
include 'david.php';
exit();
}

david.php

<?php // david.php

// Define Variables
$father_name = $_SESSION[$father_name];
$father_relationship = $_SESSION[$father_relationship];
$father_interests = $_SESSION[$father_interests];
$father_history = $_SESSION[$father_history];
$father_occupation = $_SESSION[$father_occupation];



//print father's information
print"<h3>Relationship to Chris</h3>
      <p>$father_relationship</p>

必须在所有需要访问使用$_Session设置的数据的文件中设置/激活会话，并且设置会话应该是任何需要访问数据的脚本上的第一件事存储在Session Global Variable ....

HTML文件：

<div>
    <form action="handle_family.php" method="post">
        <p>Family Member: <select name="name">
                <option value="david">David</option>
                <option value="linda">Linda</option>
                <option value="cayla">Cayla</option>
                <option value="sophie">Sophie</option>
                <option value="sawyer">Sawyer</option>
            </select></p>
        <p>Relationship: <select name="relationship">
                <option value="father">Father</option>
                <option value="mother">Mother</option>
                <option value="wife">Wife</option>
