i have some problem with the basicly function of jquery autocomplete in codeigniter but i think that the error isnt jquery
the code:
the view:
<link rel="stylesheet" href="<?php echo base_url();>application/libraries/jquery-ui.css" type="text/css">
<script type="text/javascript" src="<?php echo base_url(); ?>application/libraries/jquery-1.10.2.js"></script>
<script type="text/javascript" src="<?php echo base_url(); ?>application/libraries/jquery-ui.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#client_name').autocomplete({
source: "<?php echo site_url('site/check_in_client/?'); ?>"
});
});
</script>
<input type="text" name="client_name" id="client_name" placeholder="nome"/>
the model:
function check_in_client($name) {
$this->db->like('name',$name, 'both');
$query = $this->db->get('client');
return $query->result();
}
the controller:
function check_in_client() {
$this->load->library('javascript');
$this->load->view('check_in_client');
if(isset($_GET['term'])) {
$result= $this->membership_model->check_in_client($_GET['term']);
if(count($result) > 0) {
foreach($result as $pr)
$arr_result[] = $pr->name;
echo json_encode($arr_result);
}
}
}
the code load a view with a blank text boxe
where is the problem?
thanks a lot by
In your view file:
<link rel="stylesheet"href="//code.jquery.com/ui/1.11.4/themes/smoothness/jqueryui.css">

<script type="text/javascript">
$(document).ready(function() {
$('#client_name').autocomplete({
source: "<?php echo site_url('site/check_in_client/?'); ?>"
});
});
</script>
<input type="text" name="client_name" id="client_name" placeholder="nome"/>
In your Model:
function check_in_client($name) {
$this->db->select('name',false);
$this->db->like('name',$name, 'both');
$query = $this->db->get('client');
if ($query->num_rows > 0) {
foreach ($query->result() as $row) {
$datas[] = $row->name;
}
echo json_encode($datas);
} else {
$datas[] = 'Oops! No suggestions found. Try a different search.';
echo json_encode($datas);
}
}
In your Controller:
function check_in_client() {
$this->load->library('javascript');
$this->load->view('check_in_client');
if(isset($_GET['term'])) {
$result= $this->membership_model->check_in_client($_GET['term']);

I am struggling to implement autocomplete on my page as no results are showing from the database.
Below is the code on the index.php page
<head> <link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/smoothness/jquery-ui.css">
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script>
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script> <script>
$(function() {
$("#tags").autocomplete({
source: "autocomplete.php"
});
});
</script> </head> <body> <label for="tags">Select Student</label> <div><input id="tags" type="text" name="tags" /> </div></body>
The autocomplete.php file looks like this...
<?php include("session.php");
session_start();
$description_arr = array();
$stmt = "select case
When (login.name is null or login.name='') and (login.surname is null or login.surname='')
then login.username
Else login.name + ' ' + login.surname
End as user_profile
from my_students
inner join login
on stud_id = login.id
where my_students.id = '$login_id'";
$ses_stmt = mysqli_query($conn, $stmt);
while($row = mysqli_fetch_array($ses_stmt)){
array_push($description_arr,$row['user_profile']);}
echo json_encode($description_arr);
?>

Always check the existence of a variable/array index before using it:
$head = isset($_POST['head']) ? $_POST['head'] : null;
//may check nullity of $head
There seem to be two things going on: First of all, the click handler for the td is not attached because the DOM was not ready, wrap your jQuery code in
$(function() {
//your code
})
Also, the click event on the tr and on the td are both fired...
When I want to include my search in index.php, slider.php just disappears.
The file search.php is combination of php and javascript and slider.php is pure javascript.
This is my index.php:
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/mhgallery.js"></script>

<script type="text/javascript" src="js/search.js"></script>
</head>
<body>
<?php include 'includes/search_form.php';?>
<?php include 'includes/slider.php';?>
</body>
</html>
This is search.php:
<?php
include 'init.php';
$output="";
if (isset($_POST['search'])){
$searchq = $_POST['search'];
$searchq = preg_replace ("#[^0-9a-z]#i","",$searchq);
$query = mysql_query("SELECT * FROM `users` WHERE `username` LIKE '%$searchq%'") or die("error");
$count = mysql_num_rows($query);
if ($count == 0){
$output = 'No resault';
}else{
while($row = mysql_fetch_array($query)){
$username = $row['username'];
$output .= '<div>'.$username.'</div>';
}
}
}
?>
This is search_form.php:
<?php include 'php_script/search.php';?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script src="search.js" type="text/javascript"></script>

<input id="srch" type="submit" value=">>"/>
</form>
<div id="output">
<?php echo ($output);?>
</div>
</div>
This is slider.php:
<div id="mhgallery">

<img src="slideshow_slike/batman.jpg" title="batman" />
<img src="slideshow_slike/hobbit.jpg" title="hobbit" />
<img src="slideshow_slike/interstellar.jpg" title="interstellar" />
<img src="slideshow_slike/sw7.jpg" title="sw7" />
</div>
This is initgallery.js:
$(document).ready(function(){$("#mhgallery").mhgallery({width:950,height:400,scaleMode:'scaleToFill',firstSlide:0,randomPlay:false,autoPlay:true,backgroundMode:'transparent',backgroundColor:'#333333',showShadow:true,showThumbShadow:true,showPause:false,showBorder:true,borderSize:6,borderColor:'#FFFFFF',showFullscreen:false,fullscreenBackgroundColor:'#333333',fullscreenThumbArrowStyle:'white',interval:3000,effectSpeed:500,showCaption:false,textCSS:'.title {font-size:12px;font-weight:bold;font-family:Arial;color:#ffffff;line-height:200%;} .alt {font-size:12px;font-family:Arial;color:#ffffff;}',captionPosition:'bottom',captionBarColor:'#333333',captionBarOpacity:0.8,captionBarPadding:8,captionAlign:'center',showNavArrows:true,autoHideNavArrows:true,arrowStyle:'white',showThumbs:false,thumbSize:40,thumbGap:8,thumbBottom:-60,thumbArrowStyle:'black',thumbOpacity:0.8,thumbBorderWidth:1,thumbBorderColor:'#FFFFFF',thumbBorderActiveColor:'#FFFFFF',effect:'fade,slideLeft,slideRight,slideTop,slideBottom',jsFolder:'js'});});
This is search.js:

$.post("search.php", {searchVal: searchTxt}, function (output){
$("#output").html(output);
});
}
I need to to do autocomplete suggestion for my website and the data should be retrieved from database. I want to use JQuery autocomplete. here is my code but it doesn't work!
This is my php file with the name of gethint.php:
<?php
require_once ('config.php');
$q=$_REQUEST["q"];
$sql="SELECT `fname` FROM `Property` WHERE fname LIKE '%$q%'";
$result = mysql_query($sql);
$json=array();
while($row = mysql_fetch_array($result)) {
$json[]=array(
'value'=> $row['fname'],
'label'=> $row['fname']
);
}
echo json_encode($json);
?>
and then this is my html file :
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js"></script>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" />
<script type="text/javascript">
$(document).ready(function(){
$("#hint").autocomplete({
source:'gethint.php',
minLength:1
});
});
</script>
</head>
<body>
<form class="sansserif" action="view.php" method="post">
Name: <input type="text" id="hint" name="hint" >
<input type="submit" name="submit" value="View">
</form>
</html>
It took a lot of time but I couldn't find the problem. I was wondering if someone could help me.
Thanks.
<?php
require_once ('..\config.php');
$q=$_REQUEST["term"];
$sql="SELECT `fname` FROM `Property` WHERE fname LIKE '%$q%'";
$result = mysql_query($sql);
while($row = mysql_fetch_array($result)) {
$json[]=array(
'value'=> $row['fname'],
'label'=> $row['fname']
);
}
echo json_encode($json);
?>
All I changed was the $_REQUEST["q"] to $_REQUEST["term"].
I did some changes, maybe you need to fix something but take a look to see if helps...
The php:
<?php
require_once ('config.php');
$q=$_REQUEST["q"];
$sql="SELECT `fname` FROM `Property` WHERE fname LIKE '%$q%'";
$result = mysql_query($sql);
$json=array();
while($row = mysql_fetch_array($result)) {
array_push($json, $row['fname']);
}
echo json_encode($json);
?>
The html+jquery:
<html>

</head>
<body>
<form class="sansserif" action="view.php" method="post">
Name: <input type="text" id="hint" name="hint" />
<input type="submit" name="submit" value="View">
</form>
<script type="text/javascript">
$(function() {
$( "#hint" ).autocomplete({
source: function( request, response ) {
$.ajax({
url: "gethint.php",
dataType: "jsonp",
data: {
q: request.term
},
success: function( data ) {
response( data );
}
});
},
});
});
</script>
</body>
</html>
Your PHP script should be accepting a term parameter, not q.

You are using/including two separate versions of jquery, that'll be the root cause of the issue.
