Live Search Box Using PHP, MySQL and AJAX

I am trying to make an search box which to display the "Address" from MYSQL/PHP
I have used ajax to refresh page without leaving page, but when I run in browser, it always give me an error. when I used console, the return result of echo $_POST['name'] = ( html code of header.php + "What I need" + html code of footer.php )
<?php
include 'header.php';
include 'Connect.php';
if( isset($_POST['ajax']) && isset($_POST['name']) ){
echo $_POST['name'];
exit;
}
?>
<form method="POST">
<label>Username</label>
<input type="text" name="name" required="required" id='name'>
<div id='response'></div>
</form>
<script>
$(document).ready(function(){
$('#name').keyup(function(){
var name = $('#name').val();
$.ajax({
type: 'post',
url: index.php,
data: {ajax: 1,name: name},
success: function(response){
$('#response').text(response);
}
});
});
});
</script>
<?php
if(isset($_POST['name'])){
$username = $_POST['name'];
$stmt = $con->prepare("SELECT Username, FullName, Adresse, Email, Phone FROM dbo.users WHERE Username= ?");
$stmt->execute(array($username));
while($row=$stmt->fetch(PDO::FETCH_ASSOC))
{
$Username = $row["Username"];
$FullName = $row["FullName"];
$Adresse = $row["Adresse"];
$Email = $row["Email"];
$Phone = $row["Phone"];
echo "<tr>
<div>
<td>".$Username."</td>
<td>".$FullName."</td>
<td>".$sEID."</td>
<td>".$Email."</td>
<td>".$Phone."</td>
</div>
</tr>";
}
echo "</table>
</div>";
} else echo '<div class="alert alert-danger"> This Name <strong>is not exit</strong></div>';
include $tpl.'footer.php';
}
?>

Your question isn't very clear... if i understand correctly... this is broken by design, you're calling the page itself and update #name with the content of the entire page, thats why you see html + "what you need" (the response): the response is the whole page.
The right way to do this would be to move the second part of PHP code (where you perform the query ecc.) on a separate script and then call that new script by putting its name as the url parameter in the ajax call.

thank you for your respanse, i want to use the value returned by ajax to use with MYSQL/PHP to echo $row['Address'];
if i move the second part of PHP code the result is
echo $_POST['name'] = ( "What I need" + html code of footer.php )

Repeat self-processing form

My question is over creating a self-processing form that inserts to a database and then refreshes, incrementing arrays to change relevant info in the form. (though if there is an easier or better way to do this, I'm all ears).
So site is essentially a digital equivalent to an exercise journal. The user selects a template name from a select menu, then it queries the database for that template, then returns the result to a variable. The exercise names and number of sets per exercise (which will be used to calculate maximum number of form refreshes) are passed into their own respective arrays: $exerciseName[]; and $setNum[];
This is a screenshot of the form.
My question is how to go about setting up the logic so that I can keep submitting until the last set of the last exercise, where upon the final submission, would take to a different page.
I am using mysql_ functions, which I know is frowned upon, but it is for school which uses PHP 5.2.12 and that is what my teammates know so I have no other options. I haven't tried to prevent mysql injections because I don't intend to take this version online.

You can use PHP_SELF (eg <?php echo htmlentities ($ _ SERVER ['PHP_SELF']); ?>) In the action of the form. See this article which explains why we need htmlentities. This PHP_SELF variable contains the path to the current script.
All the logic you can place where you have, before the template, where you should check the following:
Did happen a page submit?
If yes, check for errors with submitted data.
If there are no errors treats and saves the information. If there are send an array with errors for the template.
If not, nothing to do.
Thus, when there is submission of the form everything will always be submitted on the same page.

Uncaught ReferenceError: output is not defined when using jQuery $.post() in file file

I have a dynamic search which uses jQuery and a PHP search file to dynamically show the results below. I just changed my log in scripts and sessions; now i am having issues with a search bar that searches through the members in a DB. When I was going through the testing I see that on each keyUp the jQuery function runs properly but there is some sort of issue inside of my search.php file. It seems like there is no $userCount or $userCount = 0 because it will display "There Were No Search Results"which only happens when it equals $userCount== 0
Here are the parts of my index.php
<script type="text/javascript">
function searchUserQ(){
var searchTxt = $("input[name='userSearch']").val();
if (searchTxt == '') {
// $.post("includes/search.php", {searchVal:searchTxt},
// function(output){
// $("#userResults").html(output);
// });
}else{
$.post("includes/search.php", {searchVal:searchTxt},
function(output){
$("#userResults").html(output);
});
console.log(output);
}
}
</script>
<form class="editUser" action="index.php" method="post">
<h1>Search For Employee</h1>
<input type="text" name="userSearch" id="userSearch" placeholder="Search For Employee By First Or Last Name | Press Space To View All Employees" onkeyup="searchUserQ();" />
<submit type="submit" />
div id="userResults">
</div>
</form>
and here is my search.php file
<?php
// this file connects to the database
include("connect.inc.php");
if(isset($_POST['searchVal'])){
// turn that the user searched into a varible
$searchQ = $_POST['searchVal'];
// delete any symbols for security
$searchQ = preg_replace("#[^0-9a-z]#i", "", $searchQ);
$output = "";
// Search through these columns inside the main database
$userSearchQuery = mysql_query("SELECT * FROM dealerEmployees WHERE
firstName LIKE '%$searchQ%' or
lastName LIKE '%$searchQ%'
");
// count the number of results
$userCount = mysql_num_rows($userSearchQuery);
if($userCount == 0){
// $output = "There Were No Search Results";
}else{
while($row = mysql_fetch_array($userSearchQuery)){
// define dynamic varibles for each loop iteration
$id = $row['id'];
$firstName = $row['firstName'];
$lastName = $row['lastName'];
$address = $row['address'];
$phone = $row['phone'];
$email = $row['email'];
$passwordQ = $row['password'];
$permission = $row['permission'];
$photo = "images/" . $row['profilePhoto'];
$output .= "<li><div class='employeeSearch' style=\"background: url('$photo'); width: 75px; height: 75px\"></div><h6>" . $firstName . "</h6>" . " " . "<h6>" . $lastName . "</h6><a href='#' class='employee' data-firstName='$firstName' data-lastName='$lastName' data-address='$address' data-phone='$phone' data-email='$email' data-password='$passwordQ' data-permission='$permission' data-id='$id'>Select Employee</a></li>";
}
}
}
echo $output;
Any suggestions why this is happening?

The reason for the error in the title is that you have console.log(output) outside the callback function. This has two problems: First, the variable output is not in scope; second, it runs immediately, not after the AJAX call returns. Move it into the callback:
function searchUserQ(){
var searchTxt = $("input[name='userSearch']").val();
if (searchTxt != '') {
$.post("includes/search.php", {searchVal:searchTxt},
function(output){
console.log(output);
$("#userResults").html(output);
});
}
}

Many spaces before javascript result

I have a login script that should return 'success' or 'failure' respectively, but it adds many spaces before the result, in the console it shows tha value as "<tons of space> success". This is the PHP for the login script:
public function login() {
global $dbc, $layout;
if(!isset($_SESSION['uid'])){
if(isset($_POST['submit'])){
$username = mysqli_real_escape_string($dbc, trim($_POST['email']));
$password = mysqli_real_escape_string($dbc, trim($_POST['password']));
if(!empty($username) && !empty($password)){
$query = "SELECT uid, email, username, password, hash FROM users WHERE email = '$username' AND password = SHA('$password') AND activated = '1'";
$data = mysqli_query($dbc, $query);
if((mysqli_num_rows($data) === 1)){
$row = mysqli_fetch_array($data);
$_SESSION['uid'] = $row['uid'];
$_SESSION['username'] = $row['username'];
$_SERVER['REMOTE_ADDR'] = isset($_SERVER["HTTP_CF_CONNECTING_IP"]) ? $_SERVER["HTTP_CF_CONNECTING_IP"] : $_SERVER["REMOTE_ADDR"];
$ip = $_SERVER['REMOTE_ADDR'];
$user = $row['uid'];
$query = "UPDATE users SET ip = '$ip' WHERE uid = '$user' ";
mysqli_query($dbc, $query);
setcookie("ID", $row['uid'], time()+3600*24);
setcookie("IP", $ip, time()+3600*24);
setcookie("HASH", $row['hash'], time()+3600*24);
echo 'success';
exit();
} else {
//$error = '<div class="shadowbar">It seems we have run into a problem... Either your username or password are incorrect or you haven\'t activated your account yet.</div>' ;
//return $error;
$err = 'failure';
echo($err);
exit();
}
} else {
//$error = '<div class="shadowbar">You must enter both your username AND password.</div>';
//return $error;
$err = "{\"result\":\"failure\"}";
echo json_encode($err);
exit();
}
}
} else {
echo '{"result":"success"}';
exit();
}
return $error;
}
and the form and JS
<div class="shadowbar"><form id="login" method="post" action="/doLogin">
<div id="alert"></div>
<fieldset>
<legend>Log In</legend>
<div class="input-group">
<span class="input-group-addon">E-Mail</span>
<input type="email" class="form-control" name="email" value="" /><br />
</div>
<div class="input-group">
<span class="input-group-addon">Password</span>
<input type="password" class="form-control" name="password" />
</div>
</fieldset>
<input type="submit" class="btn btn-primary" value="Log In" name="submit" />
</form></div>
$(function login() {
$("#login").validate({ // initialize the plugin
// any other options,
onkeyup: false,
rules: {
email: {
required: true,
email: true
},
password: {
required: true
}
}
});
$('form').ajaxForm({
beforeSend: function() {
return $("#login").valid();
},
success : function(result) {
console.log(result);
if(result == " success"){
window.location = "/index.php";
}else if(result == " failure"){
$("#alert").html("<div class='alert alert-warning'>Either you're username or password are incorrect, or you've not activated your account.</div>");
//$("#alert").show();
}
}
});
});
but the result always has a lot of spaces for some reason. I'm new to JS, so if this is common, I don't already know.
<?php
error_reporting(E_ALL); ini_set('display_errors', 1);
define("CCore", true);
session_start();
//Load files...
require_once('include/scripts/settings.php');
require_once('include/scripts/version.php');
require('include/scripts/core.class.php');
require('include/scripts/nbbc_main.php');
$parser = new BBCode;
$core = new core;
$admin = new admin;
require_once('include/scripts/layout.php');
require_once('include/scripts/page.php');
//Set Variables...
global $dbc, $parser, $layout, $main, $settings, $core;
$page = new pageGeneration;
$page->Generate();
?>
this is my index, and anything before the page is generated and login() is called, is in there.

I suppose you are using Ajax calls. I had the same problem, but it my case the result hadn't contain spaces, it was returned in new line. The problem was that my script which was requested by Ajax, contained "new line" character before the PHP script. Search your script file for spaces before PHP script starting with <?php //code... If you had included some scripts in the script which returns success note, search them as well.

I dont know if it matters but your
if(result == " success"){ // <<<<<< Here is a Problem maybe
window.location = "/index.php";
}else if(result == " failure"){ // <<<<<< Here is a Problem maybe
$("#alert").html("<div class='alert alert-warning'>Either you're username or password are incorrect, or you've not activated your account.</div>");
//$("#alert").show();
}
compares your result from the server which is i.e. "success" with " success". There is space too much.
EDIT:: I dont get ether why you jumps between the response format. Sometimes you echo "success" which is plain and good with your if condition but sometimes you return json encodes strings.
These Responses you can't just compare with plain text. These Responses you have to Parse into a JSON Object. Then you could compare with:
if (parsedJSONobject.result == "success"){}

The comments on the question are most probably correct: the spaces are being (again, probably, nobody can know for sure without reading the whole source) echoed by PHP included before this. For example, if you do:
<?php
// there's a space before the previous line
you'd get that space in the output.
What you can do is a bit of a hack, you include a header, for example:
header('Content-Type: text/html');
just before your success output, this will (yet again, probably) output something like:
Warning: Cannot modify header information - headers already sent by (output started at /some/file.php:12) in /some/file.php on line 23
(note the "output started" part) and now you know where to start looking.
HTH.

I do get new entries into the database when i fill out the form. But it does neither send me an email or UPDATE the database at the specified email. It simply updates all the entries with a blank email. The echo "$e" within the script also return nothing.
I used this code to check:
<?php
echo "<pre>";
print_r($_GET);
echo "</pre>";
$e = $_GET['e'];
echo "$e";
?>
And in this case it does return an array with [e]=cataras#gmx.de and it also prints out $e. But why doesnt it work in the other skript? I'm using the exact same methods to get e from the URL.
When i run my Javascript function:
function signup(){
var u = _("username").value;
var p1 = _("pass1").value;
var p2 = _("pass2").value;
var status = _("status");
if(u == "" || p1 == "" || p2 == ""){
status.innerHTML = "Fill out all of the form data";
} else if(p1 != p2){
status.innerHTML = "Your password fields do not match";
} else {
_("signupbtn").style.display = "none";
status.innerHTML = 'please wait ...';
var ajax = ajaxObj("POST", "signup.php");
ajax.onreadystatechange = function() {
if(ajaxReturn(ajax) == true) {
if(ajax.responseText.replace(/^\s+|\s+$/g, "") == "signup_success"){
status.innerHTML = ajax.responseText;
_("signupbtn").style.display = "block";
} else {
window.scrollTo(0,0);
_("signupform").innerHTML = "OK "+u+", check your email inbox and junk mail box at <u>"+e+"</u> in a moment to complete the sign up process by activating your account. You will not be able to do anything on the site until you successfully activate your account.";
}
}
}
ajax.send("u="+u+"&p="+p1);
}
}
I get Uncaught ReferenceError: e is not defined. And the site stops at "please wait...". I just took out the +e+ in the js to get to the php above. Sorry for the long post but i am really running out of ideas. THANKS in advance!!!

I think $_GET['e'] is not working in your original script because it's not getting passed to that processing script from your form page. I accessed the URL you provided (http://www.rockaholics-cologne.de/root/signup.php?e=cataras#gmx.de). Note that when you submit your form, the value of "e" in your URL is not being passed to whatever is processing your script. In your form, you need to either do this:
<form action="{yourscripturl}?e=<?php echo $_GET['e']?>" {rest of form tag}>
Or, add a hidden to hold the value of "e", and then use $_POST['e'] on your processing script instead of $_GET['e'].
<input type="hidden" name="e" value="<?php echo $_GET['e']?>" />
