Using EasyWeChat and PHP to develop the dynamic display function of WeChat mini programs

With the popularity and development of WeChat mini programs, more and more companies and individuals have begun to use WeChat mini programs as a display and display of their businesses. Marketing platform. The dynamic display function can make the mini program more lively and interesting, attracting users' attention and participation. In this article, we will introduce how to use EasyWeChat and PHP to implement the dynamic display function of WeChat applet.

EasyWeChat is an open source WeChat development toolkit based on PHP. It provides a wealth of interfaces and methods to help us easily interact with WeChat official accounts, WeChat payment, WeChat applets, etc. Using EasyWeChat, we can easily implement the dynamic display function of WeChat applet.

First of all, we need to apply for the AppID and AppSecret of a mini program on the WeChat open platform. Then, by introducing the EasyWeChat SDK into the PHP project, we can use Composer to manage dependencies:

require_once 'vendor/autoload.php';

use EasyWeChatFactory;

$options = [
    'app_id' => 'your-app-id',
    'secret' => 'your-app-secret',
    // ...
];

$miniProgram = Factory::miniProgram($options);

Next, we can use the interface provided by EasyWeChat to implement the dynamic display function of the WeChat applet. For example, we can use the officially provided uploadMedia() method to upload image materials and obtain the media_id of the material:

$response = $miniProgram->media->uploadImage('path/to/image.jpg');
$mediaId = $response['media_id'];

Then, we can use createWXAQRCode()Method generates a mini program code and saves it to the server:

$response = $miniProgram->app_code->getUnlimit($scene, [
    'page'  => 'pages/index/index', // 需要跳转的页面
    'width' => 300, // 小程序码的宽度
]);

if ($response instanceof EasyWeChatKernelHttpStreamResponse) {
    $response->saveAs('path/to/qrcode.jpg');
}

Next, we can send dynamically displayed content to users through the template message function of the WeChat mini program. First, we need to set up the template message template in the WeChat public platform background and obtain the template_id of the template. Then, we can use the sendTemplateMessage() method provided by EasyWeChat to send the template message:

$templateData = [
    'touser'      => 'user-openid',
    'template_id' => 'your-template-id',
    'page'        => 'pages/index/index', // 需要跳转到的页面
    'form_id'     => 'your-form-id',
    'data'        => [
        'keyword1' => '动态展示标题',
        'keyword2' => '动态展示内容',
        // ...
    ],
];

$response = $miniProgram->template_message->send($templateData);

Above, we introduced how to use EasyWeChat and PHP to implement the dynamic display function of the WeChat applet. By uploading picture materials, generating mini program codes and sending template messages, we can achieve dynamic display effects, thereby attracting users' attention and participation. I hope this article can be helpful to you when developing WeChat mini programs.
