How do I send data and return data from the server-side PHP, properly?

Masonh928 · January 17, 2015

Here's the code that deals with the client side:

<?php 
session_start(); 
if(!isset($_SESSION['Logged_in'])){
header("Location: /page.php?page=login");
}
?>
<!DOCTYPE Html>
<html>
<head>
<!--Connections made and head included-->
<?php require_once("../INC/head.php"); ?>
<?php require_once("../Scripts/DB/connect.php"); ?>
<!--Asynchronously Return User Names-->
<script>
$(document).ready(function(){
function search(){
        var textboxvalue = $('input[name=search]').val();
        $.ajax(
        {
            type: "GET",
            url: 'search.php',
            data: {Search: textboxvalue},
            success: function(result)
            {
                $("#results").html(result);
            }
        });
};
</script>
</head>
<body>
<div id="header-wrapper">
<?php include_once("../INC/nav2.php"); ?>
</div>
<div id="content">
<h1 style="color: red; text-align: center;">Member Directory</h1>
<form onsubmit="search()">
         <label for="search">Search for User:</label>
<input type="text" size="70px" id="search" name="search">
</form>
         <a href="index.php?do=">Show All Users</a>|<a href="index.php?do=ONLINE">Show All Online Users</a>
<div id="results">
<!--Results will be returned HERE!-->
</div>

search.php

<?php
//testing if data is sent ok
echo "<h1>Hello</h1><br>" . $_GET['search'];
?>

This is the link I get after sending foo.

Is that mean it was sent, but I'm not processing it correctly? I'm new to the whole AJAX thing.
