SearchView Suggestions over Network in Android

Post Views: 1,794

Hello Friends, Today we’ll see an example of SearchView Suggestions over Network in Android. And there will be two part of this code one will be server side code in PHP and another one Android app code. Actually I was working on an android app in which I was required to add search suggestion over network feature in that, So now I am sharing this sample code almost same as I have developed for the app just to help others and me in future projects. If you want to know how to use SearchView in toolbar before proceeding with suggestion over network you can checkout this post.

Let’s code now without wasting any time..

Server Side PHP Code

config.php

<?php
date_default_timezone_set("Asia/Kolkata");

define("DATABASE_NAME", "YOUR-DB-NAME");

function getConnection() {
    $servername = "localhost";
    $username = "YOUR-USERNAME";
    $password = "YOUR-PASSWORD";

    // Create connection
    $conn = new mysqli($servername, $username, $password, DATABASE_NAME);
    // Check connection
    if (mysqli_connect_error()) {
        die("Database connection failed: " . mysqli_connect_error());
    } else {
        return $conn;
    }
}

define("KEY", "SECUREKEY");

<?php

date_default_timezone_set("Asia/Kolkata");

define("DATABASE_NAME", "YOUR-DB-NAME");

function getConnection() {

$servername = "localhost";

$username = "YOUR-USERNAME";

$password = "YOUR-PASSWORD";

// Create connection

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

// Check connection

if (mysqli_connect_error()) {

die("Database connection failed: " . mysqli_connect_error());

} else {

return $conn;

}

define("KEY", "SECUREKEY");

api.php

<?php
include_once 'config.php';

header("Content-Type:application/json");
if (!isset($_REQUEST['key']) || trim($_REQUEST['key']) != KEY) {
    die("Not authorised");
}
if (!isset($_REQUEST['action'])) {
    echo "Please provide action parameter";
    die();
}
$action = trim($_REQUEST['action']);

if ($action == 'get-search-suggestions') {
    $conn = getConnection();
    //check get parameter or request parameter or post parameter and respond accordingly    
    if (isset($_REQUEST['term'])) {
        $term = filter_var(trim($_REQUEST['term']), FILTER_SANITIZE_STRING);
        $results = $conn->query("SELECT id, name, color, size, price FROM items WHERE name LIKE '%{$term}%' OR color LIKE '%{$term}%' OR size LIKE '%{$term}%' OR price LIKE '%{$term}%' LIMIT 5");
        echo $conn->error;
        $suggestions = array();
        while ($row = $results->fetch_assoc()) {
            $suggestions[] = $row;
        }
        respond("200", "Search Suggestions", $suggestions);
        exit();
    }
}

function respond($status, $status_message, $data) {
    header("HTTP/1.1 $status $status_message");
    $response['status'] = $status;
    $response['status_message'] = $status_message;
    $response['data'] = $data;

    echo json_encode($response);
}
