열 수정 및 삭제
이전 장에서는 열 기능과 열 표시 목록을 추가했습니다. 표시 페이지에는 다음 코드가 있습니다.
<td>
<a class="link-update" href="cate_edit.php?id=<?php echo $v['id'];?>">修改</a>
<a class="link-del" onclick="return confirm('确定删除当前数据？')" href="cate_del.php?id=<?php echo $v['id']; ?>">删除</a>
</td>여기서 표시해야 하는 해당 열 ID를 얻었습니다. 해당 페이지 이 ID를 받은 후 데이터베이스 작업을 통해 컬럼 수정 및 삭제를 완료할 수 있습니다.
먼저 수정 기능을 수행하겠습니다. 수정 페이지를 클릭하면 다음 페이지로 들어갑니다.
여기서 데이터베이스에 추가된 파일을 꺼내고 데이터를 표시합니다. 페이지 코드는 다음과 같습니다.
<?php
include_once('../../common/config.php');
$id=$_GET['id'];
$sql="select * from cate WHERE id='$id'";
$que=mysqli_query($conn,$sql);
$row=mysqli_fetch_assoc($que);
function getList($pid=0,&$result=array(),$spac=0)
{
global $conn;
$spac +=4;
$sql = "select * from cate where pid = $pid";
$res = mysqli_query($conn,$sql);
while($rows=mysqli_fetch_array($res))
{
$rows["name"] = str_repeat(' ',$spac).'|--'.$rows["name"];
$result[] = $rows;
getList($rows['id'],$result,$spac);
}
return $result;
}
$rs=getList();
//print_r($rs);
//die;
?>

</script>데이터를 꺼낸 후 해당 페이지로 데이터를 전송한 후 sql문을 사용하여 데이터베이스에 저장하는 것도 가능합니다. 이 페이지의 데이터를 변경하세요. 데이터 수정을 받는 페이지의 코드는 다음과 같습니다.
<?php
include_once('../../common/config.php');
$id=$_POST['id'];
$name=$_POST['name'];
$modelid=$_POST['modelid'];
$status=$_POST['status'];
$keywords=$_POST['keywords'];
$content=$_POST['content'];

echo "该分类不存在";
exit;

// print_r($sql);
// die;

echo "<script>alert('修改成功');location.href='cate_list.php';</script>";
}else{
echo "<script>alert('修改失败，请检查后在提交');Location.href='cate_edit.php';</script>";
}
}자, 이제 수정이 완료되었습니다. 삭제를 시작하겠습니다. .
삭제 시 주의할 점은 우리 컬럼이 2차 분류를 가지고 있기 때문에 최상위 카테고리를 삭제하려면 최상위 카테고리 아래의 하위 카테고리를 먼저 삭제해야 한다는 점입니다. 삭제는 허용되지 않습니다.
