How to Develop a Real Estate Search Feature in WeChat Mini Program Using PHP

With the rapid growth of WeChat Mini Programs, real estate search has become a common feature for developers. This article explains step by step how to implement a real estate search function, from database design and PHP API development to Mini Program integration.

Creating the Database Table

First, create a table in the database to store real estate information. For example, create a table named houses with fields id, name, location, and price.

Connecting to the Database Using PHP

You can connect to the database using mysqli or PDO. Example code:

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

Querying Real Estate Information

Use an SQL query to retrieve real estate information and store the results in an array:

// Query real estate data from the database
$sql = "SELECT * FROM houses";
$result = $conn->query($sql);

$houses = array();
if ($result->num_rows > 0) {
    // Store query results in an array
    while($row = $result->fetch_assoc()) {
        $house = array(
            "id" => $row["id"],
            "name" => $row["name"],
            "location" => $row["location"],
            "price" => $row["price"]
        );
        array_push($houses, $house);
    }
}

Returning Data in JSON Format

WeChat Mini Programs use JSON for data communication, so convert the query result to JSON and return it:

// Convert query results to JSON
$response = array(
    "code" => 200,
    "message" => "Query successful",
    "data" => $houses
);

// Convert array to JSON string
$json_response = json_encode($response);

// Return JSON string
header('Content-Type: application/json');
echo $json_response;

Calling the PHP API in Mini Program

In the WeChat Mini Program, use wx.request to call the PHP API and get the data:

wx.request({
    url: 'http://yourdomain.com/your_php_api.php',
    method: 'GET',
    success: function(res) {
        console.log(res.data)
        // Handle the returned real estate data here
    },
    fail: function() {
        console.log('Request failed')
    }
})

Summary

Following these steps, you can implement a real estate search feature in a WeChat Mini Program using PHP. For real-world applications, you can add filters, pagination, and security measures to make the system more robust and reliable. This article provides a basic example to help developers quickly set up a real estate search feature.
