How to use PHP to implement the subscription function of the mall

With the rise of e-commerce, the marketing methods of online malls are becoming more and more diversified. Among them, the subscription function is a very popular marketing tool. Through the subscription function, merchants can send regular updates, promotions and other information to users, thereby improving user retention and conversion rates. This article will introduce in detail how to use PHP to implement the subscription function of the mall.

1. Basic implementation methods of the subscription function

There are two main implementation methods of the subscription function of the mall:

1. Email subscription: The user enters his or her email address, and the merchant Send subscription information to this email address.

2. SMS subscription: The user enters his or her mobile phone number, and the merchant sends the subscription information to the mobile phone number.

Whether it is email subscription or SMS subscription, merchants need to save the information entered by the user into the database to facilitate the later use of marketing information.

2. Implementation process

1. Design database table

Before implementing the subscription function, you first need to design the corresponding database table. The following is a simple subscription table design:

CREATE TABLE subscribe (
id int(11) unsigned NOT NULL AUTO_INCREMENT,
email varchar(100) NOT NULL COMMENT 'Email',
phone varchar(11) DEFAULT NULL COMMENT 'Mobile phone number',
create_time int(11 ) unsigned NOT NULL COMMENT 'Creation time',
update_time int(11) unsigned DEFAULT NULL COMMENT 'Update time',
PRIMARY KEY (id)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='Subscription Form';

2. Write a subscription page

The subscription page of the mall needs to contain a form and a submit button. The form contains information that the user needs to fill in, such as email address and mobile phone number.

After the user fills out the form and clicks the submit button, the user input needs to be verified. For example, verify that the user entered the correct email address or mobile phone number.

If the content entered by the user is verified, the information entered by the user needs to be saved in the database. This can be achieved using database operation tools such as PDO.

3. Implement email subscription

After the subscription page is submitted successfully, the merchant needs to send the subscription information to the user's email address. PHP provides the mail function, which can easily implement the mail sending function.

The content sent by email can be in HTML format. For example, you can set the email content to an email thanking the user for subscribing and providing detailed instructions for the subscription information. The following is a simple email sending sample code:

$email = $_POST['email'];
$subject = 'Thank you for subscribing! ';
$message = '

';
$message .= '

Thank you for subscribing!

';
$message .= '

The following is the message you subscribed to:

';
$message .= '

Email: '. $ email .'

';
$message .= '';
$headers = 'MIME-Version: 1.0' . "
";
$headers .= 'Content-type: text/html; charset=utf-8' . "
";
$headers .= 'From: Your Shop Name ' . "
";
mail($email, $subject, $message, $headers);

4. Implement SMS subscription

After the subscription page is submitted successfully, the merchant Subscription information needs to be sent to the user's mobile phone. There are two ways to send SMS messages, one is through SMS API, and the other is through SMS gateway.

To send text messages through the SMS API, you need to introduce the corresponding SMS API library and configure it according to the documentation. The following is a sample code for sending text messages through SMS API:

$phone = $_POST['phone'];
$content = 'Thank you for subscribing! The following is the information you subscribe to: Mobile phone number: '. $phone;
//Configure SMS API parameters
$config = [

'url' => 'http://smsapi.example.com/',
'username' => 'yourusername',
'password' => 'yourpassword',
'apikey' => 'yourapikey',
'mobile' => $phone,
'content' => $content

];
//Use curl to send text messages
$ch = curl_init();
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_URL,$config['url']);
curl_setopt($ch,CURLOPT_POST ,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query($config));
$result = curl_exec($ch);
curl_close($ch);

Via SMS For the gateway to send text messages, you need to purchase the service of the SMS gateway and configure it according to the documentation. The specific implementation methods are slightly different, so I won’t go into details here.
