Why is my alert not being displayed on success call

I am trying to work out why my alert in the 'function processResponse(data)' part of the code, is not being displayed. I have tried various return; options, but still, refuses to display.
I would be grateful if someone could point out my error. Many thanks.
PS. I am aware of security issues in the code posted such as mysql_escape_string, but all security issues will be inserted before the site goes live.
jQuery code
<script type="text/javascript">
$(function() {
$('#srcsubmit').click(function(e) {
e.preventDefault();
if ($('#srcBox').val() == '') {
notif({
type: "error",
msg: "<b>ERROR:<br /><br />You must enter a search term</b><p>Click anywhere to close</p>",
height: 99,
multiline: true,
position: "middle,center",
fade: true,
timeout: 3000
});
return false;
}
$("#submit").prop("disabled", true);
$("#submit2").prop("disabled", true);
$("#submit3").prop("disabled", true);
var value = $('#srcBox').val();
var dept = '<?php echo $_GET['dept ']; ?>';
var qString = 'sub=' + encodeURIComponent(value) + '&dept=' + encodeURIComponent(dept);
$.post('sub_db_handler.php', qString, processResponse);
});
function processResponse(data) {
if (data === 'true') {
alert('That box is not on the system'); <--- this is the problem
return;
}
$('#srcBoxRslt').val(data);
};
});
</script>
PHP backend
<?php session_start(); ?>
<?php
$con = mysql_connect("localhost","root","");
if(!$con) { die('Could not connect: ' . mysql_error()); }
mysql_select_db("sample", $con);
$dept = trim($_POST['dept']);
$custref = trim($_POST['sub']);
$result = mysql_query("SELECT * FROM boxes WHERE custref = '".$custref."'");
$found = mysql_num_rows($result);
if ($found == 0)
{
echo trim('true');
} else {
$query = "SELECT * FROM boxes WHERE department = '".$dept."' AND status = 1 AND custref = '".$custref."'";
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_array($result) or die(mysql_error());
$r = $row['custref'];
$str = json_encode($r);
echo trim($str, '"');
}
?>

The data value is not equal to true because of extra space to get rid of extra use .trim()

Autocomplete Multiple Values in Codeigniter

I have problem with autocomplete in Codeigninter and Jquery
I have a controller
<?php
public function search() {
$user = $_GET['term'];
$query = $this
->db

->like('nama_kota', $user)
->get('kota');
if ($query->num_rows() > 0) {
foreach ($query->result_array() as $row) {
$row_set[] = htmlentities(stripslashes($row['nama_kota']));
}
echo json_encode($row_set);
}
}

whats wrong guys please help me, Thanks

which type off output you need If you need like this
eg.
name,
address,
blood_group.
with output of Autocomplete call

Sorry For late reply I am very very busy in my work
this is JS call to Controller
<script>
jQuery("#h_student_name").autocomplete({
minLength: 0,
source: "DropdownController/hostel_students/" + $("#h_student_name").val(),
autoFocus: true,
scroll: true,
dataType: 'jsonp',
select: function (event, ui) {
jQuery("#h_student_name").val(ui.item.contactPerson);
jQuery("#h_student_id").val(ui.item.code);
}
}).focus(function () {
jQuery(this).autocomplete("search", "");
});
</script>
and this is controller for call
<?php
//Hostel Student Auto compelete
public function hostel_students(){
$term = trim(strip_tags($this->input->get('term')));
if( $term == ''){
$like = $term;
$result_set = $this->DropdownModel->hostel_students(array('hostel_status_id' => 1));
$labels = array();
foreach ($result_set as $row_set) {
$labels[] = array(
'label' => $row_set->student_name.' S/D '.$row_set->father_name.' ,Form# '.$row_set->form_no.' ',
'code' => $row_set->hostel_id,
'value' => $row_set->student_name,
);
}
$matches = array();
foreach($labels as $label){
$label['value'] = $label['value'];
$label['code'] = $label['code'];
$label['label'] = $label['label'];
$matches[] = $label;
}
$matches = array_slice($matches, 0, 10);
echo json_encode($matches);
} else if($term != ''){
$like = $term;
$result_set = $this->DropdownModel->hostel_students(array('hostel_status_id' => 1), $like);
$labels = array();
foreach ($result_set as $row_set) {
$labels[] = array(
'label' => $row_set->student_name.' S/D '.$row_set->father_name.' ,Form# '.$row_set->form_no.' ',

}
$matches = array();
foreach($labels as $label){
$label['value'] = $label['value'];

$label['label'] = $label['label'];
$matches[] = $label;
}
$matches = array_slice($matches, 0, 10);
echo json_encode($matches);
}
}
?>
and this is model for call
<?php
// Hostel student autocomplete
public function hostel_students($where, $like = NULL){
if($like):
$this->db->like('student_name', $like);
$this->db->or_like('form_no', $like);
$this->db->or_like('college_no', $like);
endif;
$this->db->join('student_record', 'student_record.student_id=hostel_student_record.student_id');
return $this->db->where($where)->get('hostel_student_record')->result();
}
}
?>

get different name from jquery autocomplete

I'm using this function to get autocomplete on input value
<input type="text" id="product_name">
$( '#product_name' ).autocomplete({
source:'autocomplete.php',
minLength:2,
select: function(event,ui){
$('#product_name').val( ui.item.name );
}
});
but the line
$('#product_name').val( ui.item.name );
doesn't work...
From php I store in json, "value" that is product name with different attribute, and in "name", ONLY the product name
Then, when I search with 2 digits, the results are like
product1 - qt:0 - price:20
product2 - qt:4 - price:7
product3 - qt:3 - price:11
and when I select I want to update my input only with name that is stored in ui.item.name
This is my autocomplete.php
$sql = "SELECT name, CONCAT (quantity,' - ',name,' - ',price) AS value
FROM `product` ";
$res= $db->query($sql);
while ($r = $res->fetch()) {
$a_json_row["name"] = r['name'];
$a_json_row["value"] = $r['value'];
array_push($a_json, $a_json_row );
}
echo json_encode($a_json);
flush();
Json returned from autocomplete.php is:
[{
"name": "MOCCOLO 60X165",
"value": "[12] - MOCCOLO 60X165 : 4.00"
}, {
"name": "MOCCOLO 80X150",
"value": "[19] - MOCCOLO 80X150 : 6.50"
}, {
"name": "MOCCOLO 80X200",
"value": "[69] - MOCCOLO 80X200 : 8.00"
}]
This is when I search
This is when I select
But I want

First, your php was at fault. Your ide/editor should have warned of such a simple mistake. You need to invest on better tools..
$sql = "SELECT name, CONCAT (quantity,' - ',name,' - ',price) AS value
FROM `product` ";
$a_json = [];
$res = $db->query($sql);
while ($r = $res->fetch()) {
$a_json[] = [
"name" => $r['name'],
"value" => $r['value']
];
}
header('Content-type: application/json');
echo json_encode($a_json);
flush();
Then, your JS should be like this:
$('#product_name').autocomplete({
source: "autocomplete.php",
minLength: 2,
select: function(event, ui) {
$('#product_name').val(ui.item['name']);
return false;
}
});
Working example.

Can jQuery UI Autocomplete use values from multiple input fields

I've been struggling with this code for a while and honestly I'm stuck.
This is how my auto-complete script looks like:
jQ19(function(){
// minLength:1 - how many characters user enters in order to start search
jQ19('#location_name').autocomplete({
source:'adress.php',
minLength:2,
select: function(event, ui){
// just in case you want to see the ID
var accountVal = ui.item.value;
console.log(accountVal);
// now set the label in the textbox
var accountText = ui.item.label;
jQ19('#location_name').val(accountText);
return false;
},
focus: function( event, ui ) {
// this is to prevent showing an ID in the textbox instead of name
// when the user tries to select using the up/down arrow of his keyboard
jQ19( '#location_name' ).val( ui.item.label );
return false;
}
});
});
Some more js to get me the additional value:
<script type='text/javascript'>
$('#city').on( 'change', function () {
var x = document.getElementById('city').value;
$.ajax({
type: 'post',
url: 'http://localhost/profsonstage/account/_compettions/autocomplate/location_name.php',
data: {
value: x
},
success: function( data ) {
console.log( data );
}
});
});
</script>*/
And the php that fetches the data results:
try {
$con = new PDO("mysql:host={$host};dbname={$db_name}", $username, $password);
}catch(PDOException $exception){ //to handle connection error
echo "Connection error: " . $exception->getMessage();
}
// get the search term
$city = $_GET['city'];
$b = explode(" ",$city); //get rid of the city code
$a =$b[0];
$search_term = isset($_REQUEST['term']) ? $_REQUEST['term'] : "";
//query to search for data
$query = "SELECT * from locations where adress like '%$search_term%' and city=='$a'
LIMIT 0 , 5";
The problem is when the user types a value in the input for the #City the query looks like this:
$query = "SELECT * from locations where adress like '%%' and
city=='SomeCity'
LIMIT 0 , 5";
and when we go to the next input that (is supposed to be autocomplete too and start typing) the query looks like
$query = "SELECT * from locations where adress like '%input to autocomplate%' and
city==''
LIMIT 0 , 5";
Basically I can't figure out a way to pass the values at the same time. Any help will be appreciated.

You can use following;
jQ19(function(){
// minLength:1 - how many characters user enters in order to start search
jQ19('#location_name').autocomplete({
minLength:2,
select: function(event, ui){
// just in case you want to see the ID
var accountVal = ui.item.value;
console.log(accountVal);
// now set the label in the textbox
var accountText = ui.item.label;
jQ19('#location_name').val(accountText);
return false;
},
source: function( request, response ) {
var term = request.term;
$.getJSON( "address.php?term=" + term + "&city=" + $("#city").val(), request, function( data, status, xhr ) {
response( data );
});
},
focus: function( event, ui ) {
// this is to prevent showing an ID in the textbox instead of name
// when the user tries to select using the up/down arrow of his keyboard
jQ19( '#location_name' ).val( ui.item.label );
return false;
}
});
});
And in your php file;
try {
$con = new PDO("mysql:host={$host};dbname={$db_name}", $username, $password);
}catch(PDOException $exception){ //to handle connection error
echo "Connection error: " . $exception->getMessage();
}
// get the search term
$city = $_GET['city'];
$b = explode(" ",$city); //get rid of the city code
$a =$b[0];
$search_term = isset($_REQUEST['term']) ? $_REQUEST['term'] : "";
//query to search for data
$query = "SELECT * from locations where adress like '%$search_term%' and city=='$a'
LIMIT 0 , 5";
//Fetch your data and respond json

jquery autocomplete dont return suggestions data onselec

I have input with id aktForm_tiekejas and is jquery autocomplete code:
$('#aktForm_tiekejas').autocomplete({
serviceUrl: '_tiekejas.php',
width: 185,
deferRequestBy: 0,
noCache: true,
onSelect: function(suggestion) {alert('You selected:'+suggestion.value+','+suggestion.data);}
});
_tiekejas.php:
<?php
include("../Setup.php");
$query = ($_GET['query']);
$reply = array();
$reply['query'] = $query;
$reply['suggestions'] = array();
$reply['data'] = array();
$res = mysql_query("SELECT id,pavadinimas FROM sarasas_tiekejas WHERE pavadinimas LIKE '%$query%' ORDER BY pavadinimas ASC");
while ($row = mysql_fetch_array($res)) {
$reply['suggestions'][] = $row['pavadinimas'];
$reply['data'][] = $row['id'];
}
mysql_close();
echo json_encode($reply);
?>
If query is 'vac' php returns from server:
{"query":"vac","suggestions":["UAB Vivacitas"],"data":["866"]}
but
alert('You selected:'+suggestion.value+','+suggestion.data);
doesn't alert data (866)
why?...

Probably because suggestion.value doesn't exist. Looking at your JSON response code I can see the suggestion.data but no suggestion.value. Since JS will be looking for a value that doesn't exist it will throw an error. Also you're missing out the array for the second part of the return. Try this:
alert('You selected: '+suggestion.data[0]);
If you need to iterate through your data subsets do something like:
for(i in suggestion.data){
alert('You selected: '+suggestion.data[i]);
}
