php - 复选框值插入空白？

Question

我有一个程序，我想在其中插入根据复选框值动态生成的复选框值和图像字段。所有复选框名称和所有图像名称都相同。所有其他数据均已成功插入，但未插入复选框值。请帮我。我的 php 代码是:

<?php
include_once('connection.php');
$msg='';
$prod_imgs='';
if(isset($_REQUEST['submit']))
{
    $category_id=$_REQUEST['category']; 
    $product_id=$_REQUEST['product'];
    $relation_id=$_REQUEST['relation'];
    $occasion_id=$_REQUEST['occasion'];
    $prod_image = $_FILES['prod_image']['name'];
    $tmp_prod_image=$_FILES['prod_image']['tmp_name'];
    for($i=0;$i<count($prod_image);$i++)
    {

        if($prod_image[$i]!='')
        {
            $image="product_images/".$prod_image[$i];
            //$occasion=$occasion_id[$i];
            $insert=mysql_query("insert into tbl_add_product_occasion  values('','$category_id','$product_id','$relation_id','$occasion_id','$image')");
        if($insert)
        {
            $msg="your product info added successfully";
        }
        else
        {
            $msg="an error occur";
        }
    }
    }
echo $msg;
}
?>

&html 代码是:

<script type="text/javascript">
function get_product(cat){      
                                  // alert(cat);
                                   $.ajax({
                                      type : "POST",
                                      url : 'ajax_get_product.php',
                                      data : 'cat=' +cat,
                                      success : function(data){
                                        //alert(data);
                                        document.getElementById('prod').innerHTML=data;
                                            //society_code').innerH''TML=data.d;
                                         }
                                      });

        };

尝试使用这个

<?php
include_once('connection.php');
$msg='';
$prod_imgs='';
if(isset($_REQUEST['submit']))
{
    $category_id=$_REQUEST['category']; 
    $product_id=$_REQUEST['product'];
    $relation_id=$_REQUEST['relation'];
    $occasion=$_REQUEST['occasion'];
    $prod_image = $_FILES['prod_image']['name'];
    $tmp_prod_image=$_FILES['prod_image']['tmp_name'];
    for($i=0;$i<count($prod_image);$i++)
    {

        if($prod_image[$i]!='')
        {
            $image="product_images/".$prod_image[$i];
            $occasion_id=$occasion[$i];
            $insert=mysql_query("insert into tbl_add_product_occasion  values('','$category_id','$product_id','$relation_id','$occasion_id','$image')");
            if($insert)
            {
              $msg="your product info added successfully";
            }
            else
            {
               $msg="an error occur";
            }
         }
      }
      echo $msg;
}
?>
