I am trying to execute a search on database. My goal is to take a search form and use ajax to request PHP to return a result. Problem is, I am not getting a response in ajax handleRequest function. Also, how do I send back a xml response from php. Here is my code. Sorry for the clutter.

Above codes are Javascript codes. Error says in Javascript and How to fix that?
The error occurs in the JS code and is due to the HTML generated in PHP which is missing an id attribute.
You seem to get the error here: document.getElementById(tabid).value = tabname; because document.getElementById(tabid) is null.
When it looks for the element with id str_tab it doesn't find it. The only element in the HTML which could be the desired one has the attribute name="str_tab" and it's your hidden field. You have to add the missing id="str_tab" attribute to this hidden field.
I'm trying to make htmlRows to work. When I select productcode I want to trigger func Choise() and fill price and name.
<script>
// get Product Code
<?php
$connect = new PDO("mysql:host=localhost;dbname=praktika", "root", "");
function fill_productCode($connect)
{
$output = '';
$query = "SELECT * FROM services";
$statement = $connect->prepare($query);
$statement->execute();
$result = $statement->fetchAll();
foreach ($result as $row) {
$output .= '<option value="' . $row["code"] . '">' . $row["code"] . '</option>';
}
return $output;
}
?>
var count = $(".itemRow").length;
$(document).on('click', '#addRows', function() {
count++;
var htmlRows = '';
htmlRows += '<tr>';
htmlRows += '<td><input class="itemRow" type="checkbox"></td>';
htmlRows += '<td><select id="selectUsers" onChange="Choice();" type="text" name="productCode[]" class="form-control" autocomplete="off"><option value="">Select</option><?php echo fill_productCode($connect); ?></select></td>';
// htmlRows += '<td><input type="text" id="serviceName" name="productName[]" class="form-control" autocomplete="off"></td>';
htmlRows += '<td><input type="text" id="productName_' + count + '" name="productName[]" class="form-control" autocomplete="off"></td>';
htmlRows += '<td><input type="number" name="quantity[]" id="quantity_' + count + '" class="form-control quantity" autocomplete="off"></td>';
htmlRows += '<td><input type="number" name="price[]" id="price_' + count + '" class="form-control price" autocomplete="off"></td>';
htmlRows += '<td><input type="number" name="total[]" id="total_' + count + '" class="form-control total" autocomplete="off"></td>';
htmlRows += '</tr>';
$('#invoiceItem').append(htmlRows);
});

As mentioned in the comment, it is best to move PHP script to their own page.
PHP - getServices.php
<?php
$connect = new PDO("mysql:host=localhost;dbname=praktika", "root", "");
$statement = $connect->prepare("SELECT * FROM services");
$statement->execute();
$result = $statement->fetchAll();
$output = "";
foreach ($result as $row) {
$output .= '<option value="' . $row["code"] . '">' . $row["code"] . '</option>' . "\r\n";
}
echo $output;
?>
You can then GET this via AJAX when needed.
$.get("getServices.php", function(h){
$("#selectUsers").html(h);
});
This would make a GET Request and the PHP would output the HTML back to the request.
It would be better to set this more like an API. Where a GET request can get JSON data back and then manipulate as needed with jQuery.
jQuery
$(function() {
function getData(page) {
var results;
$.getJSON(page, function(data) {
results = data;
});
return results;
}
function addRow(tObj) {
var c = $("tbody tr", tObj).length;
var newRow = $("<tr>");
$("<td>").appendTo(newRow); // 0
$("<input>", {
class: "itemRow",
type: "checkbox"
}).appendTo($("td", newRow));
$("<td>").appendTo(newRow); // 1
var sUser = $("<select>", {
id: "selectUsers",
name: "productCode[]",

This would be potential PHP code:
PHP - getUsers.php
<?php
$connect = new PDO("mysql:host=localhost;dbname=praktika", "root", "");
$statement = $connect->prepare("SELECT * FROM users");
$statement->execute();
$result = $statement->fetchAll();
$output = array();
foreach ($result as $row) {
array_push($output, $row);
}
header('Content-Type: application/json');
echo json_encode($output);
$statement = null;
$connect = null;
?>
I'm trying to generate a form, posting to an xml doc but the code keeps taking the else option "Please make sure you filled in the fields correctly." in the registration.php file when I've supplied the variables properly.

I think you're missing a key equals sign here (inside registerCustomer() function):
"...firstname=" + firstname + "&lastname" + lastname + "&password="
Contrast with:
"...firstname=" + firstname + "&lastname=" + lastname + "&password="
This means the GET index lastname is never being set.
Here I am uploading this link http://harvey.binghamton.edu/~rnaik1/myForm.html where you can see how my scroll up n down button is working in javascript but now I am working with Ajax request to a php script on the server to retrieve all of the data from the database table.
Here is the link for the work i have done:http://harvey.binghamton.edu/~rnaik1/myScrollform.html
Everything is working fine for me except scroll up and scroll down button.
Once you add 5 records in a list after entering 6th record it will show latest 5 records.
I want to make the scrollup and down button working for myScrollform.html in the same way as in myForm.html. Any help would be helpful to me and appreciated.

How get the textbox array value to store in database...

<head>
<script type="text/javascript">
var max = 4; //highest number to go to
var currentIndex = 0;
function btnClick() {
if(currentIndex < max){
currentIndex++;
postClick();
}
}
function Previous(){
if(currentIndex>0){
currentIndex--;
postClick();
}
}
function postClick() {//whatever you want to happen goes here
var sahans = new Array();
sahans[currentIndex] == d;
var d = document.getElementById("div");
d.innerHTML = "<p><input type='text' name='name"+currentIndex+"[]'>";
d.innerHTML += "<p><input type='text' name='topic"+currentIndex+"[]'>";
document.getElementById("div").style.display = "";
}
</script>
</head>

<input type="button" value="Next" onclick="btnClick();" />
<div id="div"></div>
</div>
</form>
</body>
</html>
JavaScript:
function store(form) {
var input = form.getElementsByTagName('input');
var myarray = Array();
for (var i = 0; i < input.length; i++) {
if (input[i].getAttribute('type') == 'text') {
myarray[input[i].getAttribute('name')] = input[i].value;
}
}
for (var i in myarray) {
alert(i + ': ' + myarray[i]);
}
}
HTML:
<form onsubmit="store(this); return false">
<p>
<input type="text" name="name" /><br />
<input type="text" name="topic" />
</p>
<p>
<input type="submit" value="Store in database" />
</p>
</form>
Edit:
Ok, now I made a full example with AJAX and the actual saving to the database. The AJAX call uses 'POST'. Simply fill in the number of fields that you want in the max variable.
JavaScript:
var max = 10;
var current = 0;
function goto(form, pos) {
current += pos;
form.prev.disabled = current <= 0;
form.next.disabled = current >= max - 1;
var fields = form.getElementsByTagName('fieldset');
for (var i = 0; i < fields.length; i++) fields[i].style.display = 'none';
fields[current].style.display = 'block';
form['name' + current].focus();
}
function store(form) {
var input = form.getElementsByTagName('input');
var data = '';
for (var i = 0; i < input.length; i++) {
if (input[i].getAttribute('type') == 'text')
data += '&' + input[i].getAttribute('name') + '=' + input[i].value;
}
data = encodeURI('n=' + max + data);
var xhr = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject('Microsoft.XMLHTTP');
xhr.open('POST', 'store.php', true);
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xhr.setRequestHeader('Content-length', data.length);
xhr.setRequestHeader('Connection', 'close');
xhr.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
if (this.responseText != '')
alert(this.responseText);
else {
form.submit.value = 'Saved!';
setTimeout(function() { form.submit.value = 'Save to database' }, 500);
}
}
}
xhr.send(data);

window.onload = function() {
var form = document.forms[0];
var container = form.getElementsByTagName('div')[0];
container.innerHTML = '';
for (var i = 0; i < max; i++)
container.innerHTML += '<fieldset><legend>Entry ' + (i + 1) + ' / ' + max + '</legend><input type="text" name="name' + i + '" /><br /><input type="text" name="topic' + i + '" /></fieldset>';
goto(form, 0);
}
HTML:
<form action="submit.php" method="post" onsubmit="store(this); return false">
<p>
<input type="button" name="prev" onclick="goto(this.form, -1)" value="Previous" />
<input type="button" name="next" onclick="goto(this.form, +1)" value="Next" />
</p>
<div>
<noscript>Please enable JavaScript to see this form correctly.</noscript>
</div>
<p>
<input type="submit" name="submit" value="Store in database" />
</p>
</form>
Users who have JS disabled will see what's in the <noscript> tag, otherwise it's replaced with the fieldsets. Also it's good to make an alternative submit page (submit.php) for users who have JS disabled. Below is store.php, the AJAX submit script.
PHP (store.php):
<?php
if (empty($_POST['n']) || $_POST['n'] < 1) die('Invalid request!');
$fields = array('name', 'topic');
$errors = '';
for ($i = 0; $i < $_POST['n']; $i++) {
foreach ($fields as $field) {
if (empty($_POST[$field . $i]))
$errors .= '- ' . $field . ' ' . ($i + 1) . "\n";
}
}
if ($errors != '')
die("Please fill in the following fields:\n" . $errors);
$db = mysql_connect('localhost', 'root', '');
mysql_select_db('mydb', $db);
for ($i = 0; $i < $_POST['n']; $i++) {
$name = mysql_real_escape_string($_POST['name' . $i]);
$topic = mysql_real_escape_string($_POST['topic' . $i]);
mysql_query(' INSERT INTO entries (id, name, topic) VALUES (' . $i . ', "' . $name . '", "' . $topic . '")
ON DUPLICATE KEY UPDATE name = "' . $name . '", topic = "' . $topic . '"
') or die('Database error!');
}
mysql_close($db);
?>
The output text of this script (if there is an error) is displayed in the JavaScript alert.
I hope it's working for you now.
This would be help ful for you
