在getJSON jquery中传递输入值

i have an <input> box that requires user to enter their ID number. upon entering i want to print the associated name of that ID from mysql via JSON.

my question is, how do i pass the ID value in javascript/jquery

$('input#name-submit').on('click', function () { //get the ID input
    var id = $('input#name').val(); // store it in this string

     $.getJSON("fetch.php", {id: id}, function(data) { //pass the ID in fetch.php
        $.each(data.member, function(key, value) { 
            $("#print").text(data.emp[key]["name"]);

        });
    });

my fetch.php (not the actual, but this is how i thought it goes)

if (isset['id'] == true {
    require 'db.php';

$query = "select * from `members` where `member_no` = '[id]'";
$result = $db->($query);

$myArray = array();
while ($row = mysqli_fetch_array($result)) 
       array_push($myArray, array('name' => $row [1]);

echo json_encode(array("result" => $myArray));
}

the missing piece im looking are

• how to pass the id value to my fetch.php via javascript and query the associated name for that ID
• correct logic syntax of my fetch.php to display the query into a JSON format, fetch the result and display it on $("#print") div.

Replace

if (isset['id'] == true {

with

if (isset($_GET['id'])) {
     -----^^^^^^^^^^^^---

OR

if (isset($_REQUEST['id'])) {
     -----^^^^^^^^^^^^^^^---

You are using if (isset['id'] == true { which is wrong if condition to check if passed value isset or not you need to use superglobal i.e $_GET,$_POST,$_REQUEST

Same for MySQL query you are using ['id'] which behave as normal string instead you must use supergloabal as described above.

$query = "select * from `members` where `member_no` = '".$_REQUEST['id']."'";

OR

$query = "select * from `members` where `member_no` = '".$_GET['id']."'";
