使用 PHP 回显通过 html Select 发送的信息

发布于 2024-10-21 03:06:13 字数 1003 浏览 8 评论 0原文

我有 3 个选择框，一个代表日、月和年。

一旦用户选择了他们想要的日期、月份和年份，他们就会点击“发送”。

当他们单击“发送”时，我希望 PHP 回显他们的选择。

到目前为止我拥有的代码是：

<?php
$day = array(range(1,31));
$month = array(range(1,12));
$year = array(range(2011,2020));
?>
Day:
<select>
  <?php foreach($day[0]++ as $key => $value) { ?>
    <option value="<?php echo $key ?>"><?php echo $value ?></option>
  <?php }?>
</select>
<br>
Month:
<select>
  <?php foreach($month[0]++ as $key => $value) { ?>
    <option value="<?php echo $key ?>"><?php echo $value ?></option>
  <?php }?>
</select>
<br>
Year:
<select>
  <?php foreach($year[0]++ as $key => $value) { ?>
    <option value="<?php echo $key ?>"><?php echo $value ?></option>
  <?php }?>
</select>
<input type='submit' value='Send' name='poll' />

I have 3 select boxes, one for day, month and year.

Once the user chooses their desired day, month and year they click 'send'.

When they click send I want PHP to echo out their selection.

The code I have so far is:

<?php
$day = array(range(1,31));
$month = array(range(1,12));
$year = array(range(2011,2020));
?>
Day:
<select>
  <?php foreach($day[0]++ as $key => $value) { ?>
    <option value="<?php echo $key ?>"><?php echo $value ?></option>
  <?php }?>
</select>
<br>
Month:
<select>
  <?php foreach($month[0]++ as $key => $value) { ?>
    <option value="<?php echo $key ?>"><?php echo $value ?></option>
  <?php }?>
</select>
<br>
Year:
<select>
  <?php foreach($year[0]++ as $key => $value) { ?>
    <option value="<?php echo $key ?>"><?php echo $value ?></option>
  <?php }?>
</select>
<input type='submit' value='Send' name='poll' />

您所描述的内容无法单独使用 PHP 来完成。您需要使用客户端脚本来了解用户如何与 DOM 交互。有许多不同的方法可以实现这一点。最好的选择是使用 AJAX 框架，例如 jQuery（如上所述）、Prototype、Dojo 或YUI。我可能会选择 jQuery，因为如果您习惯了 css 选择器，那么它很容易上手。

首先，您需要稍微更改 html，为输入元素提供 ID 或 类名称。并且，还添加一个显示元素，在本例中为 DIV。然后你可以像这样选择那些 DOM 节点：

     <script>
        $( document ).ready( function () {
            $( '#send' ).click( function () {

                var span = document.createElement( 'span' );
                $( span ).attr( 'id', 'options' );

                $( 'select' ).each( function () {
                    $( span ).append($( this ).val() + " ");
                });                 

                $( '#show' ).html( span );

            });
        });
    </script>

What you're describing can't be done with PHP alone. You need to use client side scripting to know how the user is interacting with the DOM. There are many different ways that you could accomplish this. Your best bet is to use an AJAX framework like jQuery (as mentioned above), Prototype, Dojo, or YUI. I'd probably go with jQuery, because it's very easy to pick up if you're used to css selectors.

First off you'd change your html a little, providing ID or Class name for the input element. And, also adding a display element, in this case a DIV. Then you could select those DOM nodes like this:

     <script>
        $( document ).ready( function () {
            $( '#send' ).click( function () {

                var span = document.createElement( 'span' );
                $( span ).attr( 'id', 'options' );

                $( 'select' ).each( function () {
                    $( span ).append($( this ).val() + " ");
                });                 

                $( '#show' ).html( span );

            });
        });
    </script>
