Building a personalized online voting and survey website: Webman's Voting Application Guide
In modern society, voting and surveys are important ways to obtain people's opinions and decisions. one. With the high-speed transmission of the Internet and the advancement of digital technology, it has become easier to build a personalized online voting and survey website. This article will introduce readers to how to use Webman, a voting application, to build a personalized online voting and survey website.
Webman is an open source voting and survey application based on Web technology and developed using PHP and MySQL. It provides a clean and easy-to-use user interface that makes it easy to create, manage, and participate in polls and surveys.
First, make sure that PHP and MySQL have been installed on your server and are working properly. Next, download Webman’s source code and extract it into your server’s web root directory.
Create a new database in MySQL and create a data table named "polls" in the database. This data table is used to store all polls and surveys.
CREATE TABLE polls (
id INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY, title VARCHAR(255) NOT NULL, options TEXT NOT NULL, created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP, updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);
Easily by using the user interface provided by Webman Create a new poll. First, visit Webman's homepage and click the "Create Poll" button. Next, fill in the title and options for your poll and click the "Save" button. At this point, the vote will be saved to the database.
Use the following code sample to display polls on your website. First, connect to the database and query all votes.
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn- >connect_error) {
die("连接失败: " . $conn->connect_error);
}
//Query all votes
$sql = "SELECT * FROM polls";
$result = $conn->query( $sql);
//Output data
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) { echo "投票标题: " . $row["title"]. "<br>"; echo "投票选项: " . $row["options"]. "<br>"; // 显示投票表单 echo '<form action="vote.php" method="post">'; echo '<input type="hidden" name="poll_id" value="' . $row["id"] . '">'; echo '<input type="submit" value="投票">'; echo '</form>'; }
} else {
echo "没有找到投票";
}
$conn->close();
?>
In the code that displays the vote, we use a form to submit the vote. When the user clicks the "Vote" button, it will jump to the vote.php page and pass the voting ID as a parameter.
In the vote.php page, we need to process the user's vote. First, get the vote ID from the form and update the option count for that vote in the database.
$poll_id = $_POST["poll_id"];
//Update voting option count
$sql = "UPDATE polls SET options_count = options_count 1 WHERE id = " . $poll_id;
$conn->query($sql);
$conn->close();
?>
Through the above steps, you have successfully built a personalized online voting and survey website. Webman not only provides a simple user interface for creating and managing polls, but also provides convenient code examples for displaying and processing polls. You can secondary develop Webman according to your own needs and add more functions and extensions.
Voting and surveys are important tools for obtaining public opinions and decision-making. By using voting applications like Webman, you can more easily build personalized online voting and survey websites to meet different needs. I hope you can use the powerful functions of Webman to build a satisfactory voting application.
