Social media integration of online voting system implemented in PHP

Overview:
With the popularity and use of social media, integrating online voting system with social media Integration can greatly enhance the dissemination and participation of voting activities. This article will introduce how to use PHP to implement social media integration of an online voting system, as well as corresponding code examples.

1. Preparation:
   Before you begin, make sure that PHP and the corresponding web server have been installed correctly. At the same time, you also need to register and obtain the relevant social media developer API key, such as Facebook's application ID and key.
2. Create a voting system:
   First, we need to create a basic online voting system. This voting system can be a simple single-choice or multiple-choice voting system, or a complex scoring voting system. Here, we take a simple single-choice voting system as an example.

<?php
// 连接数据库
$mysqli = new mysqli("localhost", "用户名", "密码", "数据库名");
if ($mysqli->connect_errno) {
    die("数据库连接失败: " . $mysqli->connect_error);
}

// 获取投票选项
$query = "SELECT id, option_name FROM options";
$result = $mysqli->query($query);
$options = array();
while ($row = $result->fetch_assoc()) {
    $option_id = $row['id'];
    $option_name = $row['option_name'];
    $options[$option_id] = $option_name;
}

// 处理用户投票
if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['vote'])) {
    $option_id = $_POST['vote'];
    $query = "UPDATE options SET votes = votes + 1 WHERE id = $option_id";
    $result = $mysqli->query($query);
    if ($mysqli->affected_rows == 1) {
        echo "投票成功！";
    } else {
        echo "投票失败，请稍后再试。";
    }
}

// 显示投票选项
foreach ($options as $option_id => $option_name) {
    echo "<input type="radio" name="vote" value="$option_id">
          $option_name<br>";
}
echo "<input type="submit" value="提交投票">
     </form>";

// 关闭数据库连接
$mysqli->close();
?>

3. Add social media sharing function:
   In order to increase the spread of voting activities, we can add social media sharing buttons on the voting page so that participants can share the voting activities to your own social media accounts.

Add the following section to the code to implement the Facebook share button:

// Facebook分享按钮
echo "<a href="https://www.facebook.com/dialog/share?app_id=YOUR_APP_ID
      &display=popup&href=投票链接&redirect_uri=回调链接"
      target="_blank">分享到Facebook</a>";

Among them, YOUR_APP_ID needs to be replaced with your Facebook application ID, The voting link needs to be replaced with the actual voting page link, and the callback link can be left blank.

Similarly, you can also add sharing buttons for other social media, just replace the corresponding sharing links.

4. Monitor social media sharing statistics:
   In order to understand the participation of voting activities, we can add social media sharing statistics. For example, count the number of times a voting page is shared on Facebook.

Add the following section to the code to implement Facebook sharing statistics:

// 获取Facebook分享统计
$response = file_get_contents("https://graph.facebook.com/v11.0/?id=投票链接&fields=engagement");
$json = json_decode($response, true);
$share_count = $json['engagement']['share_count'];
echo "分享到Facebook次数: $share_count";

Among them, voting link needs to be replaced with the actual voting page link.

Similarly, you can also add sharing statistics of other social media, just replace the corresponding API link.

Summary:
Through the above steps, we successfully implemented the social media integration of the PHP online voting system. Using the sharing function of social media can increase the spread and participation of voting activities. At the same time, by monitoring social media sharing statistics, the social influence of voting activities can be understood in a timely manner. This can be very helpful in increasing the effectiveness and participation of voting campaigns.
