我如何在另一页上回显以下结果。我需要它来回应用户选择的内容。

<strong>Return</strong>            
    <select id="Date" name="Date">                      
    <option value="0">--Select date/time--</option>
    <?php  foreach ($return as $return) { ?>
        <option value="<?php echo $return; ?>"><?php echo $return; ?></option>
    <?php } ?>

由于

用户进行选择的完整代码。他们在这个页面上选择的信息是我想在另一页上回应的信息。

表格基础101:

~~~index.php~~~
<form action='the_new_page.php' method='POST'>
  <input type='text' name='first_thing'>
  <input type='hidden' name='some_hidden_guy' value='1'>
  <input type='submit' name='submit_button' value='submit'>
</form>

当用户提交上述表单时,浏览器会将其定向到the_new_page.phpthe_new_page.php将知道所有表单信息。

表单会传递namevalue,而不是您需要知道的其他内容。 id非常适用于html目的,并且作为HTML中的规则,不允许您拥有多个具有相同ID的元素。人们通常会混淆地将表单字段的id命名为与表单字段的“名称”相同,这使得学习各自的意思非常困难。

因此,在提交表格后,它将转到您的第二页,然后您可以这样做:

~~~the_new_page.php~~~
//You can then do
echo $_POST['some_hidden_guy'] //will be 1
echo $_POST['first_thing'] //Will be whatever you inserted into the text box

如果您希望表单返回当前页面,只需将action留空即可<form action=''><form method='POST'>

为多个页面保留相同的信息!

现在,这是一个非常非程序员的方法,因为你应该找到一种不必在任何页面上重复相同代码的方法。如果你不这样做,我现在就警告你。维护这个应用程序将成为一场噩梦,因为你每次想要添加新字段时都必须编辑每一页。关于这个例子。

现在,假设您已将信息传递给car.php,您现在想在carplan.php上使用它。

~~~car.php~~~
    <form action='carplan.php' method='GET or POST, whichever it is you be using using'>
        <input type='hidden' name='Date' value='<?php echo $_GET['date'] ?>'>
        <input type='hidden' name='some_other_thing' value='<?php echo $_GET['some_other_thing'] ?>'>
        <option name='plan_id'>
            <?php foreach($plans as $plan): ?>
                <select value='<?php echo $plan['id'] ?>'><?php echo $plan['name'] ?>'>
            <?php endforeach; ?>
        </option>
        <input type='submit' name='submit' value='Get That Plan'>
    </form>

最后是关于carplan.php

    ~~~carplan.php~~~
    <form action='the_next_step.php' method='GET or POST, whichever you be using'>
        <input type='hidden' name='Date' value='<?php echo $_GET['date'] ?>'>
        <input type='hidden' name='some_other_thing' value='<?php echo $_GET['some_other_thing'] ?>'>
        <input type='hidden' name='plan_id' value='<?php echo $_GET['plan_id']?>'>
        <input type='submit' name='submit' value='The next step!'>
    </form>

你可以通过......来回应这个。

echo  $_GET['Date'];

echo $_POST['Date'];

echo $_REQUEST['Date'];
