웹사이트 백엔드 모듈 소개 - 카테고리 관리 (2) 순회

이 섹션에서는 웹사이트 작성의 핵심인 매우 중요한 링크, 분류 관리에 대해 소개합니다.

카테고리 관리란? 분류관리란 사물을 범주로 분류하고, 범주별로 상이하거나 유사한 관리방법을 적용하는 것을 말합니다.

테이블을 빌드한 후 백그라운드에서 순회합니다. 먼저 cate.php를 만듭니다

코드는 다음과 같습니다.

<?php 
session_start (); 
  require_once("../config/config.php");
  if($_POST){
    $cate_name = $_POST['cate_name'];
    $pid = $_POST['pid'];
    $sql = "INSERT INTO `cate` (`cate_name`,`pid`,`rank`) values ('$cate_name','$pid',1)";
    mysql_query($sql);
  }
  $sql = "SELECT * FROM cate"; 
$result = mysql_query($sql); 
if ($result && mysql_num_rows($result)) {
      while ($row = mysql_fetch_assoc($result)) {
        $data[] = $row;
      }
    }
 ?>
