【问题描述】：
我正在尝试创建一个跨越 2 页的简单表单。我正在使用 PHP 的 $_SESSION 来存储从第一页发送到第二页的值。该表单最初位于一个页面上，并且运行良好。
这是第一页
<form action="jobsheet2.php" method="POST" class="jobform">
<!--START ADD CLIENT-->
<div class="client-type-wrapper full-width-centred">
<a href="#" id="new_customer_btn" class="btn med-btn inline-row">New Customer</a>
<a href="#" id="existing_job_btn" class="btn med-btn inline-row">Existing Customer</a>
</div>
<!--END ADD CLIENT-->
<!--START ADD CLIENT-->
<p class="new_customer_field">
<label for="new_customer">Add New Customer</label>
<input type="text" name="new_customer" class="new_customer_input" id="new_customer">
</p>
<!--END ADD CLIENT-->
<!--START CHOOSE CLIENT-->
<?php if( $clients ): ?>
<p class="select-container existing-customer">
<label for="chosen_client" class="select">Choose a Client:</label>
<select name="chosen_client" id="chosen_client">
<?php
foreach ($clients as $client ) {
echo "<option value={$client['client_name']}>{$client['client_name']}</option>";
}
?>
</select>
</p>
<?php else: ?>
echo "No rows returned";
<?php endif; ?>
<!--END CHOOSE CLIENT-->
<!--START CUSTOMER TYPE-->
<p class="select-container">
<label for="select-choice-1" class="select">Customer Type</label>
<select name="customer_type" id="customer_type">
<option value="Contract">Contract</option>
<option value="Billable">Billable</option>
</select>
</p>
<!--END CUSTOMER TYPE-->
<!--START CHOOSE DATE-->
<p class="date_picker">
<label for="date_input" class="select">Date:</label>
<div class="input_button">
<input type="date" name="date_input" id="date_input" class="date_select" data-role='datebox' data-icon="home" data-options='{"mode":"flipbox", "lockInput":true, "useFocus":true, "useNewStyle":true}'/>
<div>
</p>
<!--END CHOOSE DATE-->
<!--START CHOOSE TIME ON-->
<p>
<label for="select-choice-1" class="select">Time On:</label>
<input type="text" id="time_select_on" name="time_select_on" data-role="datebox" data-options='{"mode":"timeflipbox", "lockInput":true, "useFocus":true, "useNewStyle":true}'/>
</p>
<!--END CHOOSE TIME ON-->
<!--START CHOOSE TIME OFF-->
<p>
<label for="select-choice-1" class="select">Time Off:</label>
<input type="text" id="time_select_off" name="time_select_off" data-role="datebox" data-options='{"mode":"timeflipbox", "lockInput":true, "useFocus":true, "useNewStyle":true}'/>
</p>
<!--END CHOOSE TIME OFF-->
<!--START Job Details-->
<p>
<label for="textarea">Details of Work:</label>
<textarea name="work_details" id="work_details"></textarea>
</p>
<!--END Job Details-->
<!--START CHOOSE Technician-->
<?php if( $technicians ): ?>
<p class="select-container">
<label for="select-choice-1" class="select">Choose a Technician:</label>
<select name="chosen_tech" id="chosen_tech" data-theme="b">
<?php
foreach ($technicians as $technician ) {
echo "<option value={$technician['user']}>{$technician['user']}</option>";
}
?>
</select>
</p>
<?php else: ?>
echo "No rows returned";
<?php endif; ?>
<!--END CHOOSE Technician-->
<!--START PRINT NAME-->
<p class="print_name_field">
<label for="print_name">Print Name</label>
<input type="text" name="print_name" class="print_name_input" id="print_name">
</p>
<!--END PRINT NAME-->
<button id="submitJob" type="submit" class="btn save-job-btn">Next</button>
</form>
</div>
这是第二页
<?php
session_start();
if ( !isset($_SESSION['username']) ) {
header('Location: index.php');
die();
}
$_SESSION['chosen_client'] = $_POST['chosen_client'];
$_SESSION['customer_type'] = $_POST['customer_type'];
$_SESSION['date_input'] = $_POST['date_input'];
$_SESSION['time_select_on'] = $_POST['time_select_on'];
$_SESSION['time_select_off'] = $_POST['time_select_off'];
$_SESSION['work_details'] = $_POST['work_details'];
$_SESSION['chosen_tech'] = $_POST['chosen_tech'];
$_SESSION['print_name'] = $_POST['print_name'];
require 'config.php';
require 'functions.php';
$conn = connect($config);
if ( $conn ) {
$clients = get('client', 'client_name', $conn);
$technicians = get('technician', 'user', $conn );
}
else die('Could not connect to the database');
?>

echo $_POST['chosen_tech'];
echo $_POST['print_name'];
print_r($_POST);
print_r($_SESSION);
?>
</div>
我注意到一些非常奇怪的事情。当我回显每个单独的 $_POST 项目时，它会打印到第二页，但是当我 print_r($_POST) 时，当我在 chrome 中查看页面的源代码时，它会显示为一个空数组。
注意：我在 jQuery Mobile 应用程序中使用此表单我不确定是否会因为它使用 ajax 而有所不同。
