如何将选定的单选按钮值保存到php中的下一页?

标签: php javascript jquery

我正在做一个在线测验应用程序,当我点击下一个按钮时,我需要将所有选中的单选按钮值保留到下一页,becoz am使用分页。在下面的代码中移动到下一页时显示未定义的偏移错误。我还有一个语法错误,就像在这一行/>'。$ newoptA [$]中意外检查一样。' 我需要解决这些问题,请帮助任何人,提前谢谢

当我检查代码时,我发现你的变量$ output list数据不正确。通过以下方式取代:

你在php变量的字符串中用if条件回显:

<?php echo '.$optB[$i].' == $_POST[''.$Qid[$i].''] ? ' checked="checked"' : '';

您在$ output变量中使用的上述行不正确。您需要按以下方式更改此行:

$output .= ....//other code
$output .= ($optB[$i] == $_POST[$Qid[$i]]) ? ' checked="checked"' : '';
$output .= ......

替换上面<?php echo变量字符串中的每个$output

<强>编辑:

检查以下代码:

$outputList .='<table><tr>
              <td> '.$r.' . '.$Question[$i].'</td>
               </tr>
               <tr>  <td><input type="hidden" name="'.$Qid[$i].'" id="'.$Qid[$i].'" value="'.$Qid[$i].'" /></td>
            </tr>
              <tr>

              <td><input type="radio"  name=" '.$Qid[$i].'" id="'.$Qid[$i].'"  value="'.$optA[$i].'" 

<?php echo '.$optA[$i].' == $_POST[''.$Qid[$i].''] ? ' checked="checked"' : ''; ?>
  

//这里你在php标签内再次启动php标签。所以删除   php和       回声标签。并按照我的提及使用   使用此作为$ outputList。=($ optA [$ i] == $ _POST [$ Qid [$ i]])? 'checked =“checked”':'';   然后关闭上面的刺痛。并为其他人做同样的事。

/> 
                '.$optA[$i].'</td></tr>
                <tr> <td><input type="radio" name=" '.$Qid[$i].'" id="'.$Qid[$i].'" value="'.$optB[$i].'" <?php echo '.$optB[$i].' == $_POST[''.$Qid[$i].''] ? ' checked="checked"' : ''; ?> />
                '.$optB[$i].'</td></tr>
             <tr> <td><input type="radio" name=" '.$Qid[$i].'"  id="'.$Qid[$i].'" value="'.$optC[$i].'"  <?php echo '.$optC[$i].' == $_POST[''.$Qid[$i].''] ? ' checked="checked"' : ''; ?>/>
               '.$optC[$i].'</td></tr>
            <tr>  <td><input type="radio" name=" '.$Qid[$i].'" id="'.$Qid[$i].'"  value="'.$optD[$i].'"  <?php echo '.$optD[$i].' == $_POST[''.$Qid[$i].''] ? ' checked="checked"' : ''; ?>/>
            '.$optD[$i].'</td></tr>

            <tr>  <td><input type="hidden" name="'.$ans[$i].'" id="'.$Qid[$i].'"  value="'.$ans[$i].'" /></td>
            </tr></table>';
  

注意:如果你没有得到我说的话,请告诉我,我会的   发布修改后的代码并会修改你更多。

嗯,你可以用PHP Sessions和/或Cookies(你的情况几乎相同)但是如果出于任何原因在测验中间出现问题......你会失去所有进度,用户必须重新开始。

如果测验很短,你可以这样做,但如果它是&gt; =中等甚至长...我建议使用$_POST&amp; Forms代替分页链接。当然,同时保存进度。

有了这个,如果你想预先检查单选按钮,输入字段或任何东西......只需在下次打开该页面时调用正确的变量(可能也是另一天因为值存储在你的页面中)服务器而不是用户机器。)
祝你好运
