单击“提交”时保持表单中的数据

编辑：道歉 - 现在所有代码都粘贴在

之下

第一次抱怨新手问题 - 我一直在寻找答案和谷歌 - 我觉得这是一些简单的编码，我搞砸了。 我创建了一个表单，当您验证时，您检查同一页面上的所有数据，原始数据保存在原始表单中，以便您可以根据需要进行更改。 我有一个表格的部分，但这不起作用 - 你可以提出多个问题，每个问题最多可以有4个答案。

但每次提交时，问题和答案都会继续，但表单字段会丢失所有数据。如何将数据保存在字段中？ 非常感谢提前

您可以根据您使用的表单方法，将输入值设置为$_POST['old_value_name]或$_GET['old_value_name']。因此，您的新代码看起来像这样（假设您正在寻找问题中的密钥$ i）：

<table>
    <tr>
        <td>Question:</td>
        <td colspan="3"><input type="text" name="q[]" value="<?php echo $_POST['q'][$i] ?>"></td>
    </tr>
    <tr>
        <td>Answer 1:</td>
        <td>Answer 2:</td>
        <td>Answer 3:</td>
        <td>Answer 4:</td>
    </tr>
    <tr>
        <td><input type="text" name="a1[]" value="<?php echo $_POST['a1'][$i] ?>"></td>
        <td><input type="text" name="a2[]" value="<?php echo $_POST['a2'][$i] ?>"></td>
        <td><input type="text" name="a3[]" value="<?php echo $_POST['a3'][$i] ?>"></td>
        <td><input type="text" name="a4[]" value="<?php echo $_POST['a3'][$i] ?>"></td>
    </tr>
</table>

据我了解您的问题，您希望在将数据发送到服务器后将其保留在表单中。

＆＃34;我已经创建了一个表单，当您验证时，您检查同一页面上的所有数据，原始数据保存在原始表单中，以便您可以根据需要进行更改＆＃34;

没关系。我记得几个月前我想要一样的。这就是我试图提供帮助的原因。

按下＆＃34;提交＆＃34;之后只有一个问题。按钮表单被发送到服务器并重新加载页面。 作为回报，您将从网络服务器获得一个新页面，您在表单字段＆＃34; action＆＃34;中指出了该页面。

我会这样做：

    Target form: <br/>
    <form id="target" action="index.php" method='post'>
        <input  name="first_field" type="text" value="<?php  if ( isset($_POST['first_field']) ) 
            echo  $_POST['first_field'];     ?>"  /> <br/>
        <input name="second_field" type="text" value="<?php if (  isset($_POST['second_field'])) 
       echo $_POST['second_field'];?>" /> <br/>            

         <p><b>What kind of girls do you like?:</b><Br>
            <input type="radio" name="browser" value="brunette" <?php if( $_POST['browser']==="brunette" ) echo "checked";  ?>  >  brunette<Br>
            <input type="radio" name="browser" value="blonde" <?php if( $_POST['browser']==="blonde" ) echo "checked";  ?>  > blonde<Br>
            <input type="radio" name="browser" value="red" <?php if( $_POST['browser']==="red" ) echo "checked";  ?> > red<Br>
         </p>


        <input type="submit" />
    </form>

鼓励任何有关如何改变/改进的想法。
