但每次我提交时，问题和答案都会进行，但表单字段会丢失所有数据。如何将数据保存在字段中？

多谢提前

您只需将输入值设置为$\u POST['old\u value\u name]或$\u GET['old\u value\u name]，具体取决于您使用的表单方法。因此，假设您正在从您的问题中查找密钥$i，那么您的新代码将如下所示：

<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>

据我所知，您的问题是希望在将值发送到服务器后将其保存在表单中。我已经创建了一个表单，当您进行验证时，您可以检查同一页面上的所有数据，原始数据保留在原始表单中，以便您可以根据需要进行更改

没关系。我记得几个月前我也想要一样的。这就是我为什么要帮忙的原因

只有一个问题是，按下提交按钮后，表单被发送到服务器，页面被重新加载。作为回报，您将从webserver获得一个新页面，您在表单字段操作中指出了该页面

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>

我们鼓励您提出如何更改/改进的想法。

a1、a2等如何获得价值？向我们展示代码。我对你所说的有问题：你可以问多个问题，每个问题最多可以有4个答案。。我有可以发布的工作代码，但关于多重问题的那部分是我困惑的地方。您只有1个问题和多个答案作为代码发布。我需要知道多个问题是如何起作用的$aa1=$_POST['a1']$aa2=$_POST['a2']$aa3=$_POST['a3']$aa4=$_POST['a4']$N=计数$aq；对于$i=1$i<$N$i++{echo Question:.$aq[$i]。回答1:回答2:回答3:回答4:.$aa1[$i]。；}}}对代码表示歉意-希望粘贴后面的内容。多个问题涉及控制表-window.onload=moreFields的js脚本；window.onload=init；onclick=this.parentNode.parentNode.removeChildthis.parentNode；好吧，我不知道JS牵涉其中，老实说，JS不是我的强项。您需要将所有代码放在您的问题中，而不是放在注释中，以便其他人能够访问您的问题，知道他们必须准确地处理什么。还要添加javascript标记@user3162674这个答案没有任何意义。名称为a1[]，它将在$\u POST中创建一个a1数组。因此，如果您需要参考您自己做的**$\u POST['a1'][key]**大家好，谢谢您的帮助-尽管数据仍然没有保存在字段中。我想这可能是我没有提供足够信息的错。此表使用js脚本运行-不确定这是否与此有关。如果使用类似于：Search:function submitform{document.myform.submit；}的javascript方法，则使用$\u GET似乎可以很好地工作。window.onload=moreFields；window.onload=init；只是试了一下，恐怕没有乐趣
