Next, you need to reference the relevant code of the WP Webcam plug-in in your theme. You can add the following code in your theme’s functions.php file:

function wpwebcam_enqueue_scripts() {
    wp_enqueue_script( 'wpwebcam', plugin_dir_url( __FILE__ ) . 'js/wp-webcam.js', array( 'jquery' ), '1.0', true );

Then, you need to write a JavaScript file in your theme that initializes the WP Webcam plugin and takes photos Add event listener for button. Create a file called wp-webcam.js and add the following code:

jQuery(document).ready(function($) {
    var videoElement = document.getElementById('cameraContainer'),
        takePhotoButton = document.getElementById('takePhotoButton');

    // 初始化WP Webcam插件
    var webcam = new Webcam(videoElement);

    // 监听拍照按钮的点击事件
    takePhotoButton.addEventListener('click', function() {
        webcam.snap(function(dataUri) {
            // 在这个回调函数中，你可以处理拍照后的数据
            console.log(dataUri);
        });
    });
});

Finally, you need to add styles to your theme to beautify the camera video stream and photo button. You can add the following code example to the CSS file of your theme:

#cameraContainer {
    width: 640px;
    height: 480px;
    border: 2px solid #000;
}

#takePhotoButton {
    margin-top: 10px;
    padding: 5px 10px;
    background-color: #007bff;
    color: #fff;
    border: none;
    border-radius: 3px;
    cursor: pointer;
}
