I have a table in a database from which I am retrieving the marks of one particular student for all 5 subjects. For Google Charts I am reading the subject name from the csv from which I have already populated the Database Table. I am passing subject name and marks as JSON object to ajax success method. But I am unable to get the chart on screen.
I have already tried debugging the code. But It is still not working.
<?php
$conn = mysqli_connect("localhost","root","","marks");
$query = "select name from tblMarks";
$result = mysqli_query($conn, $query);
?>

I want to make a like system and this is what I have so far. I can't figure out how to make it only increment once can anyone help me out? I feel like i might have to use session variables but im not sure.
index.php
<?php
$con = mysqli_connect('localhost', 'root', '','phplikes');
$query = "SELECT * FROM meme_vote ORDER BY vote DESC";
$res = mysqli_query($con, $query);

$res2 = mysqli_query($con, $sql2);
?>
Also just to let you know, I already have session variables established ie. $_SESSION['user_id'] and `$_SESSION['username']
Since you already have a user_id, I'll assume you have a users table.
You could create a new table with meme_vote_id and user_id columns, and a unique index using both fields:
CREATE TABLE `meme_voters` (
`meme_vote_id` INT UNSIGNED NOT NULL,
`user_id` INT UNSIGNED NOT NULL,
UNIQUE INDEX `unique_voter` (`meme_vote_id`, `user_id`)
);
Then when someone votes:
$sql = mysqli_query($con,"SELECT COUNT(*) AS count FROM meme_voters WHERE meme_vote_id={$id} AND user_id={$_SESSION['user_id']}" );
$rs = mysqli_fetch_object($sql);
if ( $rs->count == 0 ) {
$sql = "INSERT INTO meme_voters (meme_vote_id, user_id) VALUES ({$id}, {$_SESSION['user_id']})";
mysqli_query($con, $sql);
$sql = "UPDATE meme_vote SET vote=vote+1 WHERE id=$id";
$res = mysqli_query($con, $sql);
}
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);
?>
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?

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:

</head>
<body>
<?php include 'includes/search_form.php';?>
<?php include 'includes/slider.php';?>

This is search.php:
<?php

$searchq = $_POST['search'];
$searchq = preg_replace ("#[^0-9a-z]#i","",$searchq);

$count = mysql_num_rows($query);

$output = 'No resault';
}else{
while($row = mysql_fetch_array($query)){
$username = $row['username'];
$output .= '<div>'.$username.'</div>';

<div id="output">

This is slider.php:
<div id="mhgallery">

<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:
function searchq(){
var searchTxt = $("input [name='search']").val();
$.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:

<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({

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.
