将复选框的值保存到数据库中

首先不要使用mysql_，它已被弃用。（在CI中..您可以轻松更改它）

其次，如果您使用的是代码点火器，请使用活动记录

然后第三...

<?php
if(isset($_POST))
{
     foreach($_POST['check1'] as $rescheck)
     {
         $this->db->insert('qe_qcc', $rescheck); 
     }
 }
 ?>

或更好地使用

  <?php  $data = array();
 if(isset($_POST))
{
     foreach($_POST['check1'] as $rescheck)
     {
         $data[] = $rescheck
     }
 }
  $this->db->insert_batch('mytable', $data);
 ?>     

将所有复选框值存储在一列中：

$check_value = implode（'，'，$_POST['check1']）;

试试这个：

   $checkbox=$_POST['check1'];
        for ($i=0; $i<count($checkbox);$i++) {
         $query="INSERT INTO qe_qcc (checkbox) VALUES ('".$checkbox[$i]."')";
           mysql_query($query) or die(mysql_error());
        }

你可以使用 implode

$checkbox=implode(',', $_POST['check1']);
$query="INSERT INTO qe_qcc (checkbox) VALUES ('".$checkbox."')";
mysql_query($query) or die(mysql_error());

in HTML

<form name ="check" action="" method="POST">
<tr>
<td><input type="checkbox" name="check1[]" value="Enhance Productivity" />Enhance      Productivity</td>
<td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="checkbox" name="check1[]" value="Enhance Quality"   />Enhance Quality</td>
<td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="checkbox" name="check1[]" value="Save Time" />Save   Time</td>
<td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="checkbox" name="check1[]" value="Save Materials" />Save Materials</td>
<td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="checkbox" name="check1[]" value="Save Stock" />Save Stock</td>
<td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="checkbox" name="check1[]" value="Increase Safety" />Increase Safety</td>
<td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="checkbox" name="check1[]" value="Financial Saving" />Financial Saving</td>
<td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="checkbox" name="check1[]" value="Customer Friendly" />Customer Friendly</td>
<td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br /><br /><input type="checkbox" name="check1[]" value="Others" />Others</td>
 </tr>
<input type="submit" value="submit" />
</form>

在 PHP 中

<?php 
if(isset($_POST['check1'])){
$check = $_POST['check1'];
foreach($check as $checked) {
      $query="INSERT INTO qe_qcc (checkbox) VALUES ('".$checked."')";
      mysql_query($query) or die(mysql_error());
    }
   }
 ?>
