发出"checked value hold in value“

Question

我有一个脚本与下面的代码和分页，在那里用户可以选中复选框来缩小显示的结果，一切似乎都很好，唯一的问题是，当用户单击分页中的下一页时，结果会丢失，并显示默认结果。我认为我可能需要使用会话来存储查询或语句，但我不确定如何使用它们。如果有人能帮助我或为我指明正确的方向，我将非常感谢。

<?php
  include("config.php"); 
  $start = 0;
  $per_page = 10;
  if(!isset($_GET['page'])){
     $page = 1;
  } else
  {
      $page = $_GET['page'];
   }
   if($page<=1)
      $start = 0;
   else
      $start = $page * $per_page - $per_page;
   $sql="select id,question,correctAnswer,category from math order by id";
   $num_rows = mysql_num_rows(mysql_query($sql));
   $num_pages = $num_rows / $per_page;
   $sql .= " LIMIT $start, $per_page";
   $result=mysql_query($sql) or die(mysql_error());
   while($row=mysql_fetch_array($result))                  
   { ?>
      ..............
   <?php
     if($page > 1){
         $prev = $page - 1;
        $prev = " <a href='?page=$prev'>prev</a> ";
     } else {
        $prev = "";
     }
     if($page < $num_pages){
        $next = $page + 1;
        $next = " <a href='?page=$next'>next</a> ";
     }
    else
    {
      $next = "";
    }
    echo $prev;
    echo $next;
   ?>

下面的代码是一个接一个地选择复选框值

                               function selectall()
                                {
    var selectAll = document.forms[0].length;

    if(document.forms[0].topcheckbox.checked==true)
        {
            for(i=1;i<selectAll;i++) 
            {
            document.forms[0].elements[i].checked=true;
            }
        }
    else
        {
            for(i=1;i<selectAll;i++)

            document.forms[0].elements[i].checked=false;
        }
                  } 

                    function goSelect()
                    {
                    var select =  document.forms[0].length;
                        var checkboxes=""
                        for(i=1;i<select;i++)
                       {
                            if(document.forms[0].elements[i].checked==true)
                             checkboxes+= " " + document.forms[0].elements[i].name

                        }

                         if(checkboxes.length>0)
                             {
                               var con=confirm("You have selected ...........");         
                               if(con)
                                {

                                window.location.assign("submit.php?recsno="+checkboxes)
                               //  document.forms[0].submit()
                                }
                           }
                            else
                             {
                      alert("No record is selected.")
                 }
                       }

Answer 1

你可以使用PHP Get方法吗？然后在你的javascript中接收它。

例如:searchurl.com/results.php ts.php?box=1

然后在下一页检索它。

我相信这应该会对你有所帮助，如果你需要更多细节，请一定让我知道。

这是我所有的代码。

                      include("config.php"); 
                      $start = 0;
                      $per_page = 10;
                      if(!isset($_GET['page'])){
                      $page = 1;
                      } else{
                      $page = $_GET['page'];
                        }
                    if($page<=1)
                   $start = 0;
                      else
                 $start = $page * $per_page - $per_page;
    $sql="select id,question,correctAnswer,category from math order by id";
    $num_rows = mysql_num_rows(mysql_query($sql));
    $num_pages = $num_rows / $per_page;
    $sql .= " LIMIT $start, $per_page";
    $result=mysql_query($sql) or die(mysql_error());
    while($row=mysql_fetch_array($result))                  
    { ?>

    <tr>
         <td><input name="<?php echo $row['id']; ?>" type="checkbox" class="check"></td>
        <td><center><?php echo htmlspecialchars_decode($row['id'], ENT_QUOTES); ?></center></td>        
        <td style="padding-left:25px;margin:15px"><?php echo $_SESSION['question']= htmlspecialchars_decode($row['question'], ENT_QUOTES); ?></center></td>
        <td><center><?php echo htmlspecialchars_decode($row['correctAnswer'], ENT_QUOTES); ?></center></td>

    </tr>


        <?php } ?>
              <tr>
                <td><strong><a href="javascript:goSelect()">Select</a></strong></td>
                 <td><strong>Sr No </strong></td>

                <td><strong>View Details</strong></td>

              </tr>
            </table>
        </td>
      </tr>
      <tr>
        <td>
                   <?php
