Two or more fields with Typeahead.js

I'm having a problem with typeahead function in one of my blade.
I have a function that add more fields dynamically, and the typeahead work only on first input.
I know a missing something on script, but i don't know how to do :D
Here is my typeahead script:
<script type="text/javascript">
var path = "{{ url('software/autocomplete') }}";
$('input.typeahead').typeahead({
source: function (query, process) {
return $.get(path, { query: query }, function (data) {
return process(data);
});
}
});
</script>
Here my add fields function:
<script type="text/javascript">
$(document).ready(function(){
var postURL = "<?php echo url('addmore'); ?>";
var i=1;
$('#add').click(function(){
i++;
$('#dynamic_field').append('<tr id="row'+i+'" class="dynamic-added"><td><input type="text" name="application[]" id="application" placeholder="Nome da Aplicação" class="typeahead spinner-input form-control application_list" ><td><input type="text" name="version[]" class="form-control application_list" placeholder="Versão"></td><td width="100px"><button type="button" name="remove" id="'+i+'" class="btn btn-danger btn_remove">X</button></td></tr>');
});
$(document).on('click', '.btn_remove', function(){
var button_id = $(this).attr("id");
$('#row'+button_id+'').remove();
});
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$('#submit').click(function(){
$.ajax({
url:postURL,
method:"POST",
data:$('#add_application').serialize(),
type:'json',
success:function(data)
{
if(data.error){
printErrorMsg(data.error);
}else{
i=1;
$('.dynamic-added').remove();
$('#add_application')[0].reset();
$(".print-success-msg").find("ul").html('');
$(".print-success-msg").css('display','block');
$(".print-error-msg").css('display','none');
$(".print-success-msg").find("ul").append('<li>Record Inserted Successfully.</li>');
}
}
});
});
function printErrorMsg (msg) {
$(".print-error-msg").find("ul").html('');
$(".print-error-msg").css('display','block');
$(".print-success-msg").css('display','none');
$.each( msg, function( key, value ) {
$(".print-error-msg").find("ul").append('<li>'+value+'</li>');
});
}
});
</script>
And here is my Controller:
public function autocomplete(Request $request)
{
$datas = SoftwareList::where("application","LIKE","%{$request->input('query')}%")->get();
$dataModified = array();
foreach ($datas as $data)
{
$dataModified[] = $data->application;
}
return response()->json($dataModified);
}
Thanks advance!

How to get only the newest value response from Ajax?

I have the issue with AJAX response and display errors.
For example, when I submit my form, I see 1 in console, but If I write something in first input and submit again, then
I see:
1
2
Ajax below read 1 and 2 as both responses, so I see 2 errors but I should see only the newest, so it should be only 2.
Also, I getting value when I try to use search (invite), but Ajax skipping everything and showing only success message after Submit.
ajax.js
$(document).ready(function() {
$('#form_create_circle').submit(function(event){
event.preventDefault();
$.ajax({
url: 'form-create-circle.php',
type: 'POST',
data: $('#form_create_circle').serialize(),
dataType: 'json',
success: function(response) {
console.log(response);
if (response == 1) {
$('#title').addClass('is-invalid');
$('#invalid_title').append('<div class="invalid-feedback"><p>This field is required.</p></div>');
} else if (response == 2) {
$('#invite').addClass('is-invalid');
$('#invalid_invite').append('<div class="invalid-feedback"><p>This field is required.</p></div>');
} else if (response == 3) {
$('#color').addClass('is-invalid');
$('#invalid_color').append('<div class="invalid-feedback"><p>This field is required.</p></div>');
} else {
// success message
$('#_noti-container').append('<div class="noti noti-success noti-top-right noti-close-on-click noti-on-leave" style="z-index:100000"><div class="noti-content-wrapper"><div class="noti-content">Circle has been created!</div><div class="noti-close">×</div></div></div>');
}
}
});
return false;
});
});
form-create-circle.php
require_once($_SERVER['DOCUMENT_ROOT'].'/system/mysql/config.php');
$title = $db->EscapeString($_POST['title']);
$invite = $db->EscapeString($_POST['invite']);
$color = $db->EscapeString($_POST['color']);
$time = date('Y-m-d H:i:s');
$search = $db->QueryFetchArrayAll("SELECT * FROM user_about WHERE firstname LIKE '%".$invite."%' OR lastname LIKE '%".$invite."%'");
foreach ($search as $key) {
echo "
<div class='invite_search_cont'>
<div class='invite_search_img'><img src='{$key['profile_image']}'></img></div>
<div class='invite_search_name'>{$key['firstname']} {$key['lastname']}</div>
</div>
";
}
if ($title == '' || (!preg_match('/^[a-zA-Z0-9]+$/', $title))) {
echo 1;
} elseif ($search == '') {
echo 2;
} elseif ($color == '') {
echo 3;
} else {
$db->Query("INSERT INTO user_circle (user_id, user_added, title, color, time_added) VALUES ('{$user['id']}', '$invite', '$title', '$color', '$time')");
}
HTML
<form method='POST' id='form_create_circle'>
<div class='modal-body'>
<div>
<div class='form-group'>
<input type='text' name='title' id='title' placeholder='Family' class='form-control'>
<div id='invalid_title'></div>
</div>
<div class='form-group'>
<input type='text' name='invite' id='invite' placeholder='Search' class='form-control'>
<div id='invite_search_result'></div>
<div id='invalid_invite'></div>
</div>
<div class='form-group'>
<select name='color' id='color' class='form-control'>
<option value='0'>white</option>
<option value='1'>yellow</option>
<option value='2'>red</option>
</select>
<div id='invalid_color'></div>
</div>
</div>
</div>
<button type='submit' class='btn btn-primary' id='ajax_create_circle'>Submit</button>
</form>
<div id='_noti-container' class='noti-t-right'></div>

Sounds to me you just need to add $('#invalid_...').empty() to the start of the script before the ajax or change .append to .html
Also removeClass on all the divs involved:
$('#form_create_circle').submit(function(event) {
event.preventDefault();
$.ajax({
url: 'form-create-circle.php',
type: 'POST',
data: $('#form_create_circle').serialize(),
dataType: 'json',
success: function(response) {
console.log(response);
$('#title, #invite, #color').removeClass('is-invalid');
$("[id^=invalid]").empty(); // empty all error divs
if ("123".indexOf(response) > -1) {
var type = ["", "title", "invite", "color"][response];
$('#' + type).addClass('is-invalid');
$('#invalid_' + type).html('<div class="invalid-feedback"><p>This field is required.</p></div>');
} else {
// success message
$('#_noti-container').html('<div class="noti noti-success noti-top-right noti-close-on-click noti-on-leave" style="z-index:100000"><div class="noti-content-wrapper"><div class="noti-content">Circle has been created!</div><div class="noti-close">×</div></div></div>');
}
}
});
});

JQuery Display Alert Message on Form Submit

I am trying to display alert messages on jquery from the client side. The jquery will be called once the submit button is clicked. The form then will call the server side php. Here is my code:
FORM
<form action="branch_add_verifier.php" method="POST" id="formAdd">
<input type="text" name="id" id="id">
<input type="submit" value="submit">
</form>
JQUERY
$(document).ready(function(){
var $form = $('#formAdd');
$form.submit(function(){
var id= $("#id").val();
if (id.length < 12) {
alert("INPUT ERROR");
return false;
}
$.post($form.attr('action'), $(this).serialize(), function(response){
alert("DATA SUCCESSFULLY ADDED");
},'json');
return false;
});
});
But the alert message does not pop up inside the $.postmethod
And I also want to know how I can pop up the alert message from the server side. Here is my sample code:
SERVER SIDE
<?php $query = mysqli_query($conn, "SELECT * FROM table1
INNER JOIN table2
ON table1.col1= table2.col1
WHERE table2.col3= '".$_REQUEST['id']."'");
if (mysqli_num_rows($query) != 0) {
echo "<script>alert('ERROR')</script>";
return false;
} ?>
In summary, the code above works but I need to display messages that would tell me if the query is successful or not. Thanks
My new problem is that the code below bring me to another page:
FORM
<form action="branch_add_verifier.php" method="POST" id="formAdd">
<input type="text" name="id" id="id">
<input type="submit" value="submit">
</form>
JQUERY
$(document).ready(function(){
$('#formAdd').on('submit', function (e) {
e.preventDefault();
var id= $("#id").val();
if (id.length < 12) {
alert("INPUT ERROR");
return false;
}
$.ajax({
context: this,
url: $(this).attr('action'),
type: 'POST',
data: new FormData(this),
dataType: 'json'
}).done(function (data) {
if(data == 'ok') {
alert("DATA SUCCESSFULLY ADDED");
}
if(data == 'no') {
alert("ERROR");
}
}).fail(function (data) {
console.log('failed');
});
});
});
SERVER
$query = mysqli_query($conn, "SELECT * FROM table1
INNER JOIN table2
ON table1.col1= table2.col1
WHERE table2.col3= '".$_REQUEST['id']."'");
if (mysqli_num_rows($query) != 0) {
mysqli_close($conn);
echo json_encode('no');
return false;
}
I need to return after the json_encode because there are still methods below that.

HTML Form
<form action="branch_add_verifier.php" method="POST" id="formAdd">
<input type="text" name="id" id="id">
<input type="submit" value="submit">
</form>
Script :
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
$(function() {
$(document).on('submit', "#formAdd", function(e) {
e.preventDefault();
$.ajax({
url: $(this).attr('action'),
type: "post",
data: $(this).serialize(),
error:function(){
alert("ERROR : CANNOT CONNECT TO SERVER");
},
success: function(data) {
alert(data);
}
});
return false;
});
});
</script>
PHP server side like this:
<?php
$insert = mysqli_query($conn, "insert query here");
if($insert) {
echo json_encode('ok');
} else {
echo json_encode('no');
}
?>

Just you need to put id="id" in input type text.
<input type="text" name="id">
Working Code
$(document).ready(function(){
var $form = $('#formAdd');
$form.submit(function(){
var id= $("#id").val();
if (id.length < 12) {
alert("INPUT ERROR");
return false;
}
$.post($form.attr('action'), $(this).serialize(), function(response){
alert("DATA SUCCESSFULLY ADDED");
},'json');
return false;
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="branch_add_verifier.php" method="POST" id="formAdd">
<input type="text" id="id" name="id">
<input type="submit" value="submit">
</form>

How can I call second jquery/ajax request?

Well, I'm validating my html form with jquery/ajax request. It's process by add_contact_process.php page. In this page if data (family or given name) is exit then I'm showing a message with a button which value is Yes and Cancel.
So
1) If Yes button is press I want to call a another jquery/ajax request which save the data to db.
2) If Cancel button is press then I want to remove/hide the message.
Can someone suggest me how can I do this ?
Html form code :
<form id="addcontact">
<table width="450" border="0" cellspacing="0" cellpadding="0">
<tr>
<td>Family name</td>
<td><input type="text" name="family_name" maxlength="50" placeholder="Family name"/></td>
</tr>
<tr>
<td>Given name</td>
<td><input type="text" name="given_name" maxlength="30"placeholder="Given name"/></td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="submit" value="Add Contact" class="submit"></td>
</tr>
</table>
</form>
<script>
$("#addcontact").submit(function(event) {
event.preventDefault();
$.ajax({
type: 'POST',
url: 'add_contact_process.php',
data: $(this).serialize(),
dataType: 'json',
success: function (data) {
$('#success').html('');
$('#success').show();
$.each( data, function( key, value ) {
if(key !== 'error' && key !== 'last_id') {
$('#success').append('<p>'+value+'</p>');
}
});
if( ! data.error) {
$('#hide').hide();
setTimeout(function () {
$('input[type=submit]').attr('disabled', false);
var last_id = data.last_id;
window.location.href = "../index.php?redcdid="+last_id;
}, 5000);
}
}
});
});
$('#success').delay(3000).fadeOut('slow');
</script>
add_contact_process.php page :
<?php
$family_name = inputvalid(ucfirst($_POST['family_name']));
$given_name = inputvalid(ucfirst($_POST['given_name']));
$exitfname = mysqli_query($link, "SELECT family_name FROM contact_details WHERE family_name = '$family_name'");
$numfname = mysqli_num_rows($exitfname);
$exitgname = mysqli_query($link, "SELECT given_name FROM contact_details WHERE given_name = '$given_name'");
$numgname = mysqli_num_rows($exitgname);
$msg = array();
$msg['error'] = false;
if(empty($family_name)){
$msg[] = "<div class='error'>Family name required.</div>";
$msg['error'] = true;
}
if(strlen($given_name) > 30){
$msg[] = "<div class='error'>Given name is too big.</div>";
$msg['error'] = true;
}
// If error is not found
if($msg['error'] === false){
if(!empty($family_name) && $numfname >= 1 || !empty($given_name) && $numgname >= 1){
$msg[] = "<div class='error'>A contact with this name exists. Do you wish to continue adding this new contact?
<input type='submit' name='warning' value='yes' id='yes' class='submit' style='margin:0px;'/>
<input type='submit' name='warning' value='Cancel' id='cancel' class='submit' style='margin:0px;'/>
</div>";
$msg['error'] = true;
}else{
$query_2 = "INSERT INTO contact_details (family_name, given_name) VALUES('$family_name', '$given_name')";
$query_2 = mysqli_query($link, $query_2);
$last_id = mysqli_insert_id($link);
if($query_2){
$msg[] = "<div class='success'><strong>Successfully added a new contact</strong>. </div>";
$msg['last_id'] = "$last_id";
$another = "close";
}else{
$msg[] = "<div class='success'>Sorry we can not add a new contact details. </div>";
$msg[] .= mysqli_error();
$another = "close";
}
}
}
echo json_encode($msg);
?>

Call Second ajax within success
<script>
$("#addcontact").submit(function(event) {
event.preventDefault();
$.ajax({
type: 'POST',
url: 'add_contact_process.php',
data: $(this).serialize(),
dataType: 'json',
success: function (data) {
$('#success').html('');
$('#success').show();
$.each( data, function( key, value ) {
if(key !== 'error' && key !== 'last_id') {
$('#success').append('<p>'+value+'</p>');
}
/*------------------------------------------------------------------*/
if(confirm('Write your message here')){
/* Second ajax after clicking ok on confirm box */
$.ajax({
url : 'Second URL',
method :'POST',
data : {'data1':data1},
success:function(response){
// code after success
},
error: function(e){
return false;
}
});
}else{
$('#success').hide();
$('#success').hide();
}
/*----------------------------------------------------------*/
});
if( ! data.error) {
$('#hide').hide();
setTimeout(function () {
$('input[type=submit]').attr('disabled', false);
var last_id = data.last_id;
window.location.href = "../index.php?redcdid="+last_id;
}, 5000);
}
}
});
});

You should define the second Ajax call in first Ajax call complete method. By default Ajax call is asynchronous, it will start executing the code or statements in success method with out waiting for response from the server. you code should me like this
$.ajax({
type: 'POST',
url: 'add_contact_process.php',
data: $(this).serialize(),
dataType: 'json',
success: function (data) {
// some code
},
complete:function () {
//you second ajax call
}

using ajax to get data from a database with php [duplicate]

every type i run this it calls the error: OnError function and i can't see why it doesn't call the success: OnSuccess,
JS:
$(document).ready(function () {
// retreving data on button click
$("#data-submit").click(LoadDataThroughAjaxCall);
//loading screen functionality - this part is additional - start
$("#divTable").ajaxStart(OnAjaxStart);
$("#divTable").ajaxError(OnAjaxError);
$("#divTable").ajaxSuccess(OnAjaxSuccess);
$("#divTable").ajaxStop(OnAjaxStop);
$("#divTable").ajaxComplete(OnAjaxComplete);
//loading screen functionality - this part is additional - end
});
// ajax call
function LoadDataThroughAjaxCall() {
$.ajax({
type: "POST",
url: "Ajax/dataloader.php",
data: '{}',
dataType: "json",
success: OnSuccess,
failure: OnFailure,
error: OnError
});
// this avoids page refresh on button click
return false;
}
// on sucess get the xml
function OnSuccess(response) {
//debugger;
var xmlDoc = $.parseXML(response.d);
var xml = $(xmlDoc);
var tweets = xml.find("Table");
showOnATable(tweets);
}
// show data on a table
function showOnATable(tweets) {
//debugger;
var headers = [];
var rows = [];
// header section
headers.push("<tr>");
headers.push("<td><b>tweets</b></td>");
headers.push("<td><b>created</b></td>");
headers.push("<td><b>source</b></td>");
headers.push("</tr>");
// rows section
$.each(tweets, function () {
var tweets = $(this);
rows.push("<tr>");
rows.push("<td>" + $(this).find("tweet_text").text() + "</td>");
rows.push("<td>" + $(this).find("created_at").text() + "</td>");
rows.push("<td>" + $(this).find("source").text() + "</td>");
rows.push("</tr>");
});
var top = "<table class='gridtable'>";
var bottom = "</table>";
var table = top + headers.join("") + rows.join("") + bottom;
$("#divTable").empty();
$("#divTable").html(table);
}
// loading screen functionality functions - this part is additional - start
function OnAjaxStart() {
//debugger;
//alert('Starting...');
$("#divLoading").css("display", "block");
}
function OnFailure(response) {
//debugger;
alert('Failure!!!' + '<br/>' + response.reponseText);
}
function OnError(response) {
//debugger;
var errorText = response.responseText;
alert('Error!!!' + '\n\n' + errorText);
}
function OnAjaxError() {
//debugger;
alert('Error!!!');
}
function OnAjaxSuccess() {
//debugger;
//alert('Sucess!!!');
$("#divLoading").css("display", "none");
}
function OnAjaxStop() {
//debugger;
//alert('Stop!!!');
$("#divLoading").css("display", "none");
}
function OnAjaxComplete() {
//debugger;
//alert('Completed!!!');
$("#divLoading").css("display", "none");
}

You have to response a json from php like,
if(sqlsrv_has_rows($result) > 0) {
//Login Successful
$xml='<Table>';
while( $row = sqlsrv_fetch_array( $result, SQLSRV_FETCH_ASSOC) ) {
$xml.='<tweet_text>'.$row['tweet_text'].'</tweet_text>';
$xml.='<source>'.$row['source'].'</source>';
// create xml tag for created_at

$xml.='</Table>';
echo json_encode(array('d'=>$xml));
return TRUE;
} else {
//Login failed
echo json_encode(array('d'=>'Name not found'));
}
