PHP develops simple shopping cart function for product display
First, make a simple homepage, query several products from the database, display them on the homepage, and then add a purchase button
This is mainly for the database Operation, the SQL statement SELECT queries the product information in the database table, saves it to the goods array, and displays it in a loop on the product page
Obtain product information from the database and store it in the $goods two-dimensional array --> Remove the product Information is displayed on the page and purchasing functionality is added.
The name of the homepage is list.php
<?php
$goods = array();
//從數(shù)據(jù)庫獲取商品信息存入$goods二維數(shù)組
$i = 0;
//這里請換上自己的數(shù)據(jù)庫相關(guān)信息
$conn = mysqli_connect('localhost','username','password','test');
mysqli_set_charset($conn,"utf8");
$res = mysqli_query($conn,'select * from good');
//這里把商品信息放到$goods二維數(shù)組，每一維存的是單個
//商品的信息，比如商品稱、價格。
while ($row = mysqli_fetch_assoc($res)) {
$goods[$i]['id'] = $row['id'];
$goods[$i]['name'] = $row['name'];
$goods[$i]['price'] = $row['price'];
$i++ ;
}
