How to use PHP to develop the template message management function of public accounts

With the popularity and use of WeChat public accounts, more and more companies and individuals have begun to pay attention to how to Better interact and communicate with users. Among them, template messages are a very commonly used function and can be used to send notifications, reminders, push and other information. This article will introduce how to use PHP to develop the template message management function of public accounts and provide specific code examples.

1. Configuration of WeChat public platform

First, you need to configure the template message on the WeChat public platform. Log in to the WeChat public platform, enter the public account backend, click the "Develop - Template Message" option on the left menu bar, and enter the template message configuration page. Click the "Add Template" button, fill in the template title and template content, and select the required variables. After saving the template, you will get a template ID (template_id).

2. Introducing the Wechat-PHP-SDK library

Wechat-PHP-SDK is a WeChat public platform SDK developed in PHP, providing a wealth of APIs and functions. First, you need to introduce the Wechat-PHP-SDK library into the project. The library can be easily installed through the composer command:

composer require overtrue/wechat

3. Authorize login to obtain access_token

Using the WeChat template message function requires first obtaining the access_token for subsequent API calls. . You can set the web page authorization domain name in the background of the official account, then guide the user to jump to the authorization URL, obtain the code returned after the user authorizes it, and then exchange the code for access_token. The specific code example is as follows:

use EasyWeChatFactory;

$options = [
    'app_id' => 'your-app-id',
    'secret' => 'your-app-secret',
    'oauth' => [
        'scopes'   => ['snsapi_base'],
        'callback' => '/callback',
    ],
];

$app = Factory::officialAccount($options);

$accessToken = $app->access_token->getToken();

4. Send template message

After obtaining the access_token, you can call the API of the template message. The specific code example is as follows:

use EasyWeChatFactory;

$options = [
    'app_id' => 'your-app-id',
    'secret' => 'your-app-secret',
    'oauth' => [
        'scopes'   => ['snsapi_base'],
        'callback' => '/callback',
    ],
];

$app = Factory::officialAccount($options);

$templateId = 'your-template-id';
$openId = 'user-open-id';

$message = [
    'touser' => $openId,
    'template_id' => $templateId,
    'data' => [
        'first' => '您好，您有新的提醒：',
        'keyword1' => '提醒內(nèi)容1',
        'keyword2' => '提醒內(nèi)容2',
        'remark' => '請(qǐng)及時(shí)處理',
    ],
];

$result = $app->template_message->send($message);

5. Specific template message configuration and parameters

In the code example, templateId is configured on the WeChat public platform Template ID generated when template message. openId is the OpenID of the user who wants to send the template message. message is the content of the message to be sent, and the data part is the parameter configuration in the template message, which can be modified according to actual needs.

6. Error handling and exception capturing

In actual development, exceptions need to be handled and captured. You can use the try-catch structure to catch exceptions and perform corresponding error prompts and processing.

So far, we have completed the general process of using PHP to develop the template message management function of the public account. Through the above steps, we can easily send template messages and expand and customize more functions as needed.

Summary

This article introduces how to use PHP to develop the template message management function of public accounts and provides specific code examples. By learning and understanding these code examples, I believe readers can better grasp and apply the template message function, providing more possibilities for the development of their own WeChat official accounts.
