PHP - Simple Shopping Cart

maxos · 2025-02-27T06:33:51+0000

In this tutorial we will create a Simple Shopping Cart using PHP. PHP is a server-side scripting language designed primarily for web development. Using PHP, you can let your user directly interact with the script and easily to learned its syntax. It is mostly used by a newly coders for its user friendly environment. So Let's do the coding...

Before we get started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html.

And this is the link for the jquery that i used in this tutorial https://jquery.com/.

Lastly, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Creating Database

Open your database web server then create a database name in it db_shopping, after that click Import then locate the database file inside the folder of the application then click ok.

Creating the database connection

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

<?php
$conn

=

new

mysqli(

"localhost"

,

"root"

,

""

,

"db_shopping"

)

;
if

(

!

$conn

)

{
die

(

"Error: Failed to connect to database"

)

;
}
?>

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as shown below.

index.php

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="URF-8" name="viewport" content="width=device-width, initial-scale=1"/>

Creating PHP Query

This code contains the php query of the application. This code will sent the data inputs to the database server. To do that just copy and write this block of codes inside the text editor, then save it as save_query.php.

<?php
require_once

'conn.php'

;
if

(

ISSET

(

$_POST

[

'save'

]

)

)

{
if

(

!

empty

(

$_POST

[

'product_name'

]

)

&&

!

empty

(

$_POST

[

'product_price'

]

)

)

{
$product_name

=

addslashes

(

$_POST

[

'product_name'

]

)

;
$product_price

=

$_POST

[

'product_price'

]

;
$file

=

explode

(

"."

,

$_FILES

[

'product_image'

]

[

'name'

]

)

;
$ext

=

array

(

"png"

,

"gif"

,

"jpg"

,

"jpeg"

)

;
if

(

in_array

(

$file

[

1

]

,

$ext

)

)

{
$file_name

=

$file

[

0

]

.

'.'

.

$file

[

1

]

;
$tmp_file

=

$_FILES

[

'product_image'

]

[

'tmp_name'

]

;
$location

=

"upload/"

.

$file_name

;
$new_location

=

addslashes

$location

)

;
if

(

move_uploaded_file

(

$tmp_file

,

$location

)

)

{
$conn

->

query

(

"INSERT INTO `product` VALUES('', '$product_name

', '$product_price

', '$new_location

')"

)

;
echo

"<script>alert('Data Insert')</script>"

;
echo

"<script>window.location = 'index.php'</script>"

;
}
}

else

{

Creating Shopping Cart

This code contains the main function of the application. This code will store the database data to the PHP session, to be able to manipulate as an array. To do that just copy and write this block of codes inside the text editor, then save it as shown below.

addcart.php

<?php
session_start

(

)

;
if

(

ISSET

(

$_POST

[

'add'

'cart'

]

)

)

{
$product_array_id

=

array_column(

$_SESSION

[

"cart"

]

,

"item_id"

)

;
if

(

!

in_array

(

$_GET

[

'id'

]

,

$product_array_id

)

)

{
$count

=

count

;
$product_array
