【问题描述】：

我创建了一个下拉列表，我从一个表“类别”中获取数据（它有两列 cat_id 和类别名称），我想在另一个表 GALLERY 中插入列值..我能够获取 cat_id 但是无法获取类别名称..请帮助..SQL注入不是问题

 <?php
    include_once("header.php");
    include ("connection.php");
    if(isset($_REQUEST['ansave']))
    {
    $a=$_REQUEST['choosecategory'];
    $image=$_FILES['uploadgallery']['name'];// name given in input type 
    $ext=substr(strchr($image,'.'),1);//it breaks the string in part so that format can be matched
    if($ext!='jpg' && $ext!='jpeg' && $ext!='png' && $ext!='gif' && $ext!='JPG' && $ext!='JPEG')
    {
    echo "please select image";
    }
    else
    {
    $path="gallery/".$image; //folder in which image to be saved
    $action=copy($_FILES['uploadgallery']['tmp_name'],$path);//name given in input type (line72)
    $query="insert into gallery (`cat_id`,`galimage`) values('$a','$image')";
    $result=mysql_query($query);`enter code here`
    echo "insert successfully";
    }
    }
    ?>


         <option selected> -- select -- </option>';
           <?php $sql = "SELECT * FROM category";
        $result = mysql_query($sql);
        while($row=mysql_fetch_array($result)){
        echo '<option value="'.$row['cat_id'].'">'.$row['categoryname'].'</option>';
        }


   ?>

【问题讨论】：

不确定我是否理解这个问题。您是在创建下拉菜单时获取类别名称，还是在用户上传图片时插入类别 ID 有问题？

@Barmar 是的，它与获取类别名称有关
那么题主和实际问题有什么关系呢？
