PHP session implements the shopping cart function and session shopping cart

In the wamp environment, use PHP session control to complete the effect of the shopping cart. The data is stored in the array and the database is not connected. The effect is good and easy to understand. The following is the code of each part.

Common. php

<? Phpheader ("content-type: text/html; charset = UTF-8"); $ arrPro = array ('id' => 1, 'img '=> 'img/1.jpg', 'title' => 'xiaomi mobile power 5000mAh ', 'price' => 49), array ('id' => 2, 'img '=> 'img/2.jpg', 'title' => '20000mah Xiaomi mobile power 2', 'price' => 149 ), array ('id' => 3, 'img '=> 'img/3.jpg', 'title' => 'millet ring iron headphones Pro ', 'price' => 129), array ('id' => 4, 'img '=> 'img/4.jpg', 'title' => 'xiaomi electric scooter ', 'price' => 1999), array ('id' => 5, 'img '=> 'img/5.jpg', 'title' => 'xiaomi notebook ', 'price' => 3499), array ('id' => 6, 'img '=> 'img/6.jpg', 'title' => 'smart meters LED desk lamp ', 'price' => 169), array ('id' => 7, 'img '=> 'img/7.jpg', 'title' => 'millet scale ', 'price' => 99), array ('id' => 8, 'img '=> 'img/8.png ', 'title' => 'xiaomi TV 3 s 48 Inch ', 'price' => 2599 ));

Index. php

<? Php header ("content-type: text/html; charset = UTF-8"); require 'common. php '; session_start (); $ sum = 0; $ class = ""; // you can specify if (! Empty ($ _ SESSION ['shopcar ']) {$ data = $ _ SESSION ['shopcar']; $ sum = array_sum ($ data [4]); $ class = "on"; // the upper-right dot if (empty ($ data [0]) {$ class = "" ;}}?> <! DOCTYPE html> 
Action. php

<? Phpif (! Empty ($ _ GET ['id']) {require 'common. php '; session_start (); $ id = $ _ GET ['id']; // print the product information of the selected ID through foreach ($ arrPro as $ key => $ value) {if ($ id = $ value ['id']) {$ arrData = $ arrPro [$ key] ;}} // store product information with a new two-dimensional array $ arrDatax [0] [$ arrData ['id'] = $ arrData ['id']; $ arrDatax [1] [$ arrData ['id'] = $ arrData ['img ']; $ arrDatax [2] [$ arrData ['id'] = $ arrData ['title']; $ arrDatax [3] [$ arrData ['id'] = $ arrData ['price' ]; $ ArrDatax [4] [$ arrData ['id'] = 1; // determine whether a SESSION exists. If yes, add it after the array, if (empty ($ _ SESSION ['shopcar ']) {$ _ SESSION ['shopcar'] = $ arrDatax; header ('location: index. php ');} else {// after the first shopping, the shopping // is retrieved again to prevent data from overwriting $ arrDataz =$ _ SESSION ['shopcar']; if (in_array ($ id, $ arrDataz [0]) {$ arrDataz [4] [$ arrData ['id'] + = 1; $ _ SESSION ['shopcar '] = $ arrDataz; header ('location: index. php ');} else {$ arrDataz [0] [$ arrData ['id'] = $ ArrData ['id']; $ arrDataz [1] [$ arrData ['id'] = $ arrData ['img ']; $ arrDataz [2] [$ arrData ['id'] = $ arrData ['title']; $ arrDataz [3] [$ arrData ['id'] = $ arrData ['price']; $ arrDataz [4] [$ arrData ['id'] = 1; $ _ SESSION ['shopcar '] = $ arrDataz; header ('location: index. php') ;}} else {echo "no items in the cart! ";}
Spcar. php

<? Phpif (! Empty ($ _ GET ['id']) {require 'common. php '; session_start (); $ id = $ _ GET ['id']; // print the product information of the selected ID through foreach ($ arrPro as $ key => $ value) {if ($ id = $ value ['id']) {$ arrData = $ arrPro [$ key] ;}} // store product information with a new two-dimensional array $ arrDatax [0] [$ arrData ['id'] = $ arrData ['id']; $ arrDatax [1] [$ arrData ['id'] = $ arrData ['img ']; $ arrDatax [2] [$ arrData ['id'] = $ arrData ['title']; $ arrDatax [3] [$ arrData ['id'] = $ arrData ['price' ]; $ ArrDatax [4] [$ arrData ['id'] = 1; // determine whether a SESSION exists. If yes, add it after the array, if (empty ($ _ SESSION ['shopcar ']) {$ _ SESSION ['shopcar'] = $ arrDatax; header ('location: index. php ');} else {// after the first shopping, the shopping // is retrieved again to prevent data from overwriting $ arrDataz =$ _ SESSION ['shopcar']; if (in_array ($ id, $ arrDataz [0]) {$ arrDataz [4] [$ arrData ['id'] + = 1; $ _ SESSION ['shopcar '] = $ arrDataz; header ('location: index. php ');} else {$ arrDataz [0] [$ arrData ['id'] = $ ArrData ['id']; $ arrDataz [1] [$ arrData ['id'] = $ arrData ['img ']; $ arrDataz [2] [$ arrData ['id'] = $ arrData ['title']; $ arrDataz [3] [$ arrData ['id'] = $ arrData ['price']; $ arrDataz [4] [$ arrData ['id'] = 1; $ _ SESSION ['shopcar '] = $ arrDataz; header ('location: index. php') ;}} else {echo "no items in the cart! ";}
Delete. php
<? Phpsession_start (); if (! Empty ($ _ GET ['id']) {$ arrData = $ _ SESSION ['shopcar ']; // determine the corresponding item ID if (in_array ($ _ GET ['id'], $ arrData [0]) {unset ($ arrData [0] [$ _ GET ['id']); unset ($ arrData [1] [$ _ GET ['id']); unset ($ arrData [2] [$ _ GET ['id']); unset ($ arrData [3] [$ _ GET ['id']); unset ($ arrData [4] [$ _ GET ['id']); $ _ SESSION ['shopcar '] = $ arrData;} header ('location: spcar. php ');}
