Pengenalan modul kepada bahagian belakang laman web - Pengurusan kategori (2) Traversal
Bahagian ini akan memperkenalkan pautan yang sangat penting, pengurusan klasifikasi, yang merupakan teras penulisan laman web.
Apakah itu pengurusan kategori? Pengurusan klasifikasi bermaksud mengelaskan perkara ke dalam kategori, dan menggunakan kaedah pengurusan yang berbeza atau serupa kepada kategori yang berbeza.
Selepas membina jadual, kami akan melintasinya di latar belakang Mula-mula, buat cate.php
Kodnya seperti berikut:
<?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;
}
}
?>
