Hi friends,

I tried to build a app which is perform basic CRUD operation. This process performed from remote database. I used wamp server for this.I have 4 php file and 4 json files. i don't know how to write json file for the corresponding php file. In wamp server, inside www folder, i have all PHP files but where i can write the json files. for example,


This is the PHP file:

<?php

// array for JSON response
$response = array();

// check for required fields
if (isset($_POST['name']) && isset($_POST['price']) && isset($_POST['description'])) {

    $name = $_POST['name'];
    $price = $_POST['price'];
    $description = $_POST['description'];

    // include db connect class
    require_once __DIR__ . '/db_connect.php';

    // connecting to db
    $db = new DB_CONNECT();

    // mysql inserting a new row
    $result = mysql_query("INSERT INTO products(name, price, description) VALUES('$name', '$price', '$description')");

    // check if row inserted or not
    if ($result) {
        // successfully inserted into database
        $response["success"] = 1;
        $response["message"] = "Product successfully created.";

        // echoing JSON response
        echo json_encode($response);
    } else {
        // failed to insert row
        $response["success"] = 0;
        $response["message"] = "Oops! An error occurred.";

        // echoing JSON response
        echo json_encode($response);
    }
} else {
    // required field is missing
    $response["success"] = 0;
    $response["message"] = "Required field(s) is missing";

    // echoing JSON response
    echo json_encode($response);
}
?>

corresponding json for thr above PHP:
{
"success": 0,
"message": "Required field(s) is missing"
}
{
"success": 1,
"message": "Product successfully created."
}
{
"success": 0,
"message": "Oops! An error occurred."
}

Still i have 3 more php and json file.pls help me to solve this issue.Thanks in advance..
