Question

我正在尝试将数据发布到我拥有的网页（page3.php）。但是，当我在此页面上$test=$_POST['radio_second'];时，测试变量中没有数据。

任何人都可以搞清楚吗？非常感谢。

<p>
    <form method="post">
        <label for="radio1_0">1</label>
        <input type="radio" name="radio_second" id="radio1_0" value="1" />

        <label for="radio1_1">2</label>
        <input type="radio" name="radio_second" id="radio1_1" value="2" />

        <label for="radio1_2">3</label>
        <input type="radio" name="radio_second" id="radio1_2" value="3" checked/>

        <label for="radio1_3">4</label>
        <input type="radio" name="radio_second" id="radio1_3" value="4" />

        <label for="radio1_4">5</label>
        <input type="radio" name="radio_second" id="radio1_4" value="5" />
    </p>
</form>
</fieldset>
</div>
</div>
<a href="page1.php"  data-inline="true" data-theme="a"  data-role="button" data-direction="reverse" data-transition="slide" style="height:53px;width:150px">Prev</a>
<a href="page3.php"  data-inline="true" data-theme="a"  data-role="button" data-transition="slide" style="height:53px;width:150px">Next</a>

Answer 1

那是因为您没有将您的FORM提交给page3.php。表单中的元素只是打开page3.php而不向其提交表单。您需要用＆lt; input type =“submit”value =“Next”＆gt;替换该A元素。并将其放在＆lt; / form＆gt;之前，并将属性action =“page3.php”添加到FORM元素。或者，当用户点击链接时，您可以使用Javascript触发表单提交。

      <form method="post" action="post3.php">
        <label for="radio1_0">1</label>
         <input type="radio" name="radio_second" id="radio1_0" value="1" />
        <label for="radio1_1">2</label>
        <input type="radio" name="radio_second" id="radio1_1" value="2" />
     <label for="radio1_2">3</label>
         <input type="radio" name="radio_second" id="radio1_2" value="3" checked/>
        <label for="radio1_3">4</label>
        <input type="radio" name="radio_second" id="radio1_3" value="4" />
     <label for="radio1_4">5</label>
         <input type="radio" name="radio_second" id="radio1_4" value="5" />

     <a href="page1.php"  data-inline="true" data-theme="a"  data-role="button" data-direction="reverse" data-transition="slide" style="height:53px;width:150px">Prev</a>
     <input type="submit"  data-inline="true" data-theme="a"  data-role="button" data-transition="slide" style="height:53px;width:150px" value="Next" />

    </form>
