This section will introduce a very important link, classification management, which is the core of writing a website.
What is classification management? Classification management refers to classifying things into categories, and applying different or similar management methods to different categories.
After building the table, we will traverse it in the background. First, create a cate.php
The code is as follows:
<?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;
}
}
?>
