Being new to PHP and ajax XmlHttpRequest calls altogether, I am struggling to figure out what is wrong with my code. Gone through the documentation but it seems I'm struggling to put the db row names into an array. I ideally want to asynchronously display an innerHTML below the input to indicate whether the item is in db or not. Right now it is showing 'undefined' as seen below until I type the last item in the db. it's only responding to the last item in the db meaning there's probably an issue with my loop. Any help is welcome.

$name is not defined in your PHP file , Shouldnt it be $entry that you are checking in the elseif condition below
$entry = $_GET['name'];
if(in_array($entry, $itemArray))
echo 'Item ' .$entry. ' already exists! Please enter a new item...';
elseif ($entry == '')
echo "Please enter an item...";
else {
//code for insertion
echo "Successfully Inserted";
}
also the correct way to assign a DB column to an array should be like below .
if($rowNum > 0){
while ($row = mysqli_fetch_assoc($result)){
$itemArray[] = $row['name'];
}
} else {
echo "There are no to-dos!";
}

First of all I must say that I'm very new to website design and coding so please make your answer simple thanks a lot .
So I have my file register.php that contains my form .
I have my action file named register-controller.php that gets the data from user , checks it and inserts it to database .
What I need is that whenever the register is success , my form gets hidden or removed and my new div shows up that contains 'register successful' . ( On the same page "register.php" )
Can I use the variable that I passed to header "register=success" to do this action ? Should I use AJAX ? JSON ? what should I do ? Please give me the simplest answer thank you all .
MY "register.php" file contains these :

You can render the part of the page you prefer depending on your URL parameters by doing
<?php
if ($_GET['success']) { ?>
<-- YOUR HTML SUCCESS CODE -->
<?php } else { ?>
<-- YOUR HTML FORM CODE -->
<?php }
?>
Ajax is the best solution for me (it can be difficult to understand but the code is clean), here an example of Ajax with your situation :
Extras is the ID of all the input in the form
Page is the PHP page to be executed (register-controller.php)
Origin is the ID where you want to put the result, Origin can be null.
(To have something in the return, you have to put an echo in the php file you specified in Page)
static Ajax(origin,Extras,page)
{
var xhr = new XMLHttpRequest();
let formData = new FormData();
for(var element in Extras)
{
if(document.getElementById(element))
{
formData.append(element,document.getElementById(element));
}
else
{
let checkbox = document.getElementsByName(element);
if(checkbox)
{
//Checkbox don't work with an ID so put instead a name
for(let i=0;i<checkbox.length;i++)
{
if(checkbox[i].checked)
{
formdata.append(element+i,"1")
}
else
{
formdata.append(element+i,"0")
}
}
}
}
}
xhr.open('POST',page);
xhr.addEventListener('readystatechange', function () {
if (xhr.readyState === XMLHttpRequest.DONE && xhr.status === 200) {
let i= xhr.responseText;
if(origin!=null)
{
if(document.getElementById(origin) && xhr.responseText!="")
// the result document.getElementById(origin).innerHTML=xhr.responseText;
}
finish(i);
}
else if (xhr.readyState === XMLHttpRequest.DONE && xhr.status != 200) {
// error message XHR,
let textError = "Ajax Error : " + xhr.status + ", " + xhr.statusText + ", ";
alert(textError);
}
});
// send
xhr.send(formData);
}
I'm new to ajax. I just want to simply view my table from the database using ajax. I have 2 files listbarang.html and showlist.php.
Here's my code
PHP (showlist.php)
<?php
$link = #mysqli_connect("localhost", "root", "","projekpweb");
if($link->connect_errno)
{
echo "Failed to connect. " . $link->connect_error;
}
$sql = "SELECT * FROM `barang`";
$result = mysqli_query($link, $sql);
if(!$result)
{
die("SQL GAK KONEK : " . mysqli_error($link));
}
echo "<table>
<tr>
<th>idbarang</th>
<th>nama</th>
<th>harga</th>
<th>ekstensi_gambar</th>
</tr>";
while ($row = mysqli_fetch_array($result))
{
echo " <tr>
<td>".$row["idbarang"]."</td>
<td>".$row["nama"]."</td>
<td>".$row["harga"]."</td>
<td>".$row["ekstensi_gambar"]."</td>
</tr>";
}
echo "</table>"; ?>

Please note that password in DB Table should be md5
encrypted as in PHP, you are encrypting it to match further. If not, just remove md5 encryption from PHP Code.
hello i have a php page that is to output results in my html page using div through an ajax request medium,
i intend outpiting this results using listviews as my application targets mobile phones and tablets, so i am making use of the jquery mobile framework.
i have outputed my results successfully with this
<?php header('Access-Control-Allow-Origin: *'); ?>
<?php
$users = ($_GET['users']);
$user = ($_GET['user']);
$con = mysqli_connect('localhost','whitech3_manage','famakin','whitech3_manage');

}
mysqli_select_db($con,"whitech3_manage");
$sql="SELECT * FROM data WHERE fromwhere = '".$users."' and towhere = '".$user."'";
$result = mysqli_query($con,$sql);

echo '</head>';
while($row = mysqli_fetch_array($result)) {

echo "<li><a href='#'>". $row['time frame'] . "</a></li>";
echo "</ul>";
echo "</div>";
}
mysqli_close($con);
?>
but whenever my results are displayed they r not formatted properly to look like a listview, hence i knw i am supposed to load my style sheets and javascript tags to make sure the listview is displayed properly.
i have tried and tried to echo the links to my stylesheets and js using echo statements, but it dosent seem to make my listview show up properly.
this is what i have tried
echo '<head>';
echo "<link rel='stylesheet' href='themes/transport.min.css' />";
echo "<link rel='stylesheet' href='themes/jquery.mobile.icons.min.css' />";
echo "<link rel='stylesheet' href='themes/jquery.mobile.structure-1.4.2.min.css' />";

I hope this works. :D
So I was following a tutorial and I came across the current problem. This is my first time using the ajax method. I copied and saved jQuery version 1.7.2.min.js in a folder. My php code seems to be working fine, the only thing that seems off is the code for the ajax part.
This code is in a folder called "includes"
<div id="messages">
<!--Javascript-->
<script type= "text/javascript" src= "script/jquery-1.7.2.min.js"></script>
<script type= "text/javascript" src= "script/auto_chat.js"></script>
</div><!-- Messages -->
This is the javascript in a folder called "script" named auto_chat
$(document).ready(function() {
var interval = setInterval(function() {
$.ajax({
url: 'script/Chat.php' ,
success: function(data) {
$('#messages').html(data);
}
});
}, 1000);
});
There is a file called Chat.php containing code that links to the database.
When it runs it should show all the messages inside of the database. Instead it gives me blank and not even errors. Can someone tell me whats wrong with my method?
This is the my Chat.php
<?php
require('../includes/database/connect.db.php')
function get_msg(){
$query = "SELECT `Sender`,`Message` FROM `chat`.`chat` ORDER BY `Msg_ID` DESC";
$run = mysql_query($query);
$messages = array();
while($message = mysql_fetch_assoc($run)){
$messages[] = array('sender' => $message['Sender'],
'message' => $message['Message']);
}
return $messages;
}
function send_msg($sender, $message) {
if(!empty($sender) && !empty($message)) {
$sender = mysql_real_escape_string($sender);
$message = mysql_real_escape_string($message);
$query = "INSERT INTO `chat` . `chat` VALUES (null,'{$sender}','$message')";
if ($run = mysql_query($query)){
return true;
}else{
return false;
}
}else {
return false;
}
}
if(isset($_POST['send'])){
if(send_msg($_POST['sender'],$_POST['message'])){
echo 'Message Sent';
}else{
echo 'Message Failed to sent';
}
}
$messages = get_msg();
foreach($messages as $message) {
echo '<strong>' . $message['sender'] .' Sent</strong><br />';
echo $message['message']. '<br /><br />';
}
?>
And this is all of my index.php
<!DOCTYPE html>
<?php
require('includes/core.inc.php');
function get_msg(){
$query = "SELECT `Sender`,`Message` FROM `chat`.`chat` ORDER BY `Msg_ID` DESC";
$run = mysql_query($query);
$messages = array();
while($message = mysql_fetch_assoc($run)){
$messages[] = array('sender' => $message['Sender'],
'message' => $message['Message']);
}
return $messages;
}
function send_msg($sender, $message) {
if(!empty($sender) && !empty($message)) {
$sender = mysql_real_escape_string($sender);
$message = mysql_real_escape_string($message);
$query = "INSERT INTO `chat` . `chat` VALUES (null,'{$sender}','$message')";
if ($run = mysql_query($query)){
return true;
}else{
return false;
}
}else {
return false;
}
}
if(isset($_POST['send'])){
if(send_msg($_POST['sender'],$_POST['message'])){
echo 'Message Sent';
}else{
echo 'Message Failed to sent';
}
}
?>

After a lot of trial and error, we found out that the problem was a simple missing semicolon on chat.php:
require('../includes/database/connect.db.php');
