Autoload results fetching same results over and over - php

I have implemented the following autoload code. It fetches result from database but it keeps looping the same result over and over.
php code
<?php
require_once("config.php");
$limit = (intval($_GET['limit']) != 0 ) ? $_GET['limit'] : 10;
$offset = (intval($_GET['offset']) != 0 ) ? $_GET['offset'] : 0;
$keywords = $_GET['keywords'];
$sql = "SELECT * FROM blog_posts WHERE postCat LIKE '".$keywords."' ORDER BY postID ASC LIMIT $limit OFFSET $offset";
try {
$stmt = $DB->prepare($sql);
$stmt->execute();
$results = $stmt->fetchAll();
} catch (Exception $ex) {
echo $ex->getMessage();
}
if (count($results) > 0) {
foreach ($results as $res) {
echo '<h3>' . $res['postTitle'] . '</h3>';
}
}
?>

Try this
<?php
$keywords = 'events';
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Test</title>
<script src="bootstrap/js/jquery-1.11.1.min.js"></script>
</head>
<body>
<div class="col-lg-12" id="results"></div>
<div id="loader_image"><img src="loader.gif" alt="" width="24" height="24"> Loading...please wait</div>
<div class="margin10"></div>
<div id="loader_message"></div>
</div>
<script type="text/javascript">
var keywords = '<?php echo $keywords; ?>'; // Changed
var busy = false;
var limit = 15;
var offset = 0;
function displayRecords(lim, off) {
// Changed/New
var data = {
'limit': lim,
'offset': off,
'keywords': keywords,
};
$.ajax({
type: "GET",
async: false,
url: "getrecords.php",
data: data, // Changed
cache: false,
beforeSend: function() {
$("#loader_message").html("").hide();
$('#loader_image').show();
},
success: function(html,textStatus,jqHXR) {
$("#results").append(html);
$('#loader_image').hide();
if (html == "") {
$("#loader_message").html('<button class="btn btn-default" type="button">No records found.</button>').show()
} else {
$("#loader_message").css('display','none');
$("#loader_message").html(html);
}
window.busy = false;
},
});
}
$(document).ready(function() {
// start to load the first set of data
if (busy == false) {
busy = true;
// start to load the first set of data
displayRecords(limit, offset);
}
$(window).scroll(function() {
// make sure u give the container id of the data to be loaded in.
if ($(window).scrollTop() + $(window).height() > $("#results").height() && !busy) {
$('#result').on('scroll', function() { if($(this).scrollTop() + $(this).innerHeight() >= $(this)[0].scrollHeight) { busy = true; offset = limit + offset; setTimeout(function() { displayRecords(limit, offset); }, 500); } })
// you can remove the above code and can use directly this function
// displayRecords(limit, offset);
}
});
});
</script>
</body>
</html>

this is loading same contents over and over because on each ajax call you are sending same 'data' which is
var data = {
'limit': limit,
'offset': offset,
'keywords': keywords,
};
Change the function to use new limit and offset
function displayRecords(lim, off) {
data = {
'limit': lim,
'offset': off,
'keywords': keywords,
};
$.ajax({
type: "GET",
async: false,
url: "getrecords.php",
data: data, // Changed
cache: false,
beforeSend: function() {
$("#loader_message").html("").hide();
$('#loader_image').show();
},

jquery php mysql - how to hide load more button when all itemes displayed

I have a code for showing list from database and a loadmore button. After all records list is displayed and click on loadmore button show empty places.
How to hide loadmore button once all records displayed?
index.php file:
<?php $chinp=$_GET['schinp'];?>
<div id="schts"></div>
<button id="btnsch">load more</button>
<script>
$(document).ready(function() {
var chinp="<?php echo $chinp;?>";
var srchco = 1;
var offsrch = 0;
$("#btnsch").click(function() {
$.ajax({
method: "POST",
url: "search.php",
data: { srchcoun: srchco, offsrch: offsrch ,chinp:chinp}
})
.done(function(msg) {
$("#schts").append(msg);
});
offsrch = offsrch + srchco;
});
$("button").trigger("click");
});
</script>
search.php :
$srchcoun=$_POST['srchcoun'];
$offsrch=$_POST['offsrch'];
$chinp=$_POST['chinp'];
$schql="SELECT id, name, lastname FROM t_users WHERE name LIKE '$chinp' ORDER BY name ASC limit $offsrch, $srchcoun";
$rsch=mysqli_query($conn,$schql);
while ($rch=mysqli_fetch_assoc($rsch)){
$scid=$rch['id'];$snm=$rch['name'];$slnm=$rch['lastname'];?>
<div class="alsu">
<img class="sask" src="pic/<?php echo $scid;?>.png" alt="">
<span class="snm">Name : <?php echo $snm." ".$slnm;?></span>
</div>
<?php }?>
</div>
Thanks.
Here is code to hide load more button as per your code.
Replace this code in your first file.
<script type="text/javascript">
$(document).ready(function() {
var chinp="<?php echo $chinp;?>";
var srchco = 2;
var offsrch = 0;
var page_num = 0;
$("#btnsch").click(function() {
$.ajax({
method: "POST",
url: "search.php",
data: { srchcoun: srchco, offsrch: offsrch ,chinp:chinp, page_num : page_num}
})
.done(function(msg) {
if(msg == 'noMoreData'){
$("#btnsch").hide();
} else {
$("#schts").append(msg);
}
});
page_num = page_num + 1;
offsrch = offsrch + srchco;
});
$("#btnsch").trigger("click");
});
</script>
Now add this code in your search file.
<?php
$srchcoun=$_POST['srchcoun'];
$offsrch=$_POST['offsrch'];
$chinp=$_POST['chinp'];
$page_num=$_POST['page_num'];
$total_records = 0;
$totalschql="SELECT id FROM t_users WHERE name LIKE 'krishna' ORDER BY name ASC";
if ($result=mysqli_query($conn,$totalschql))
{
$total_records=mysqli_num_rows($result);
}
$last_records_count = ($page_num) * $srchcoun;
if($last_records_count >= $total_records) {
echo 'noMoreData';exit();
} else {
$schql="SELECT id, name, lastname FROM t_users WHERE name LIKE '$chinp' ORDER BY name ASC limit $offsrch, $srchcoun";;
$rsch=mysqli_query($conn,$schql);
while ($rch=mysqli_fetch_assoc($rsch)){
$scid=$rch['id'];$snm=$rch['name'];$slnm=$rch['lastname'];
?>
<div class="alsu">
<img class="sask" src="pic/<?php echo $scid;?>.png" alt="">
<span class="snm">Name : <?php echo $snm." ".$slnm;?></span>
</div>
<?php }?>
</div>
<?php
}
?>
Try this and let me know if you have any issue.
Simply use $('#myButtonId').hide(); in ajax part after you load the entire data from database.
function get_rain_data_list(is_load_more=0){
if(is_load_more!=0){//if is_load_more is not 0 then get offset data from btnlod attr
offset = $('#btn_load_more_rain').attr("data-offset");
}else{ //set offset =0 when is_load_more is 0
offset = 0;
}
var id = $('#id').val();
var countShow = 0;
if(fromDate!=''){
countShow = 1;
}
$.ajax({
url: base_url+"rain_data_list_ajax",
type: "POST",
data:{offset:offset,propertyId:propertyId,fromDate:fromDate,toData:toData},
dataType: "JSON",
beforeSend: function() {
show_loader();
},
success: function(data){
hide_loader();
// console.log(data);
$('.proprty_load_more_btn').remove();//remove load more button
if(offset==0){ //clear div when offset 0
$("#append_rain_list").html('');
}
if(data.no_record==0){//show data in div when no previous record
$("#append_rain_list").html(data.html_rain);

Paginate result using select 2 ajax remote data

Trying to paginate ajax data using Select2 (v 4.0.6.rc1) so that the user can find more results if not present in the first limit ,using the following but not retrieving data.I 'll appreciate if someone helps me out,there is not much of examples about pagination.
i was trying to paginate data using the help of this question Select2 v4 how to paginate results using AJAX its not seems to be working,getting the array but not correct format.
JS:
$('#compose_username').select2({
dropdownParent: $("#modal-compose") ,
placeholder: "Search Username...",
minimumInputLength: 1,
ajax: {
url: "username.php",
dataType: 'json',
delay: 250,
cache: false,
data: function (params) {
return {
term: params.term,
page: params.page || 1
//a: params.term, // search term
//psf: params.page
};
},
processResults: function(data) {
console.log(data);
var result = $.map(data, function (item) { return { id: item.id, text: item.username }});
return { results: result };
}
}
});
PHP
try{
$page= $_GET['page'];
// $resultCount = 10;
// $offset = ($page - 1) * $resultCount;
$pageLength = 20;
$pageStart = ($page - 1) * $pageLength;
$pageEnd = $pageStart + $pageLength;
$stmt = $db_con->query("SELECT id,first_name FROM datatables_demo WHERE first_name LIKE '%".$_GET['term']."%' LIMIT {$pageStart},{$pageEnd}");
$count = $db_con->query("SELECT count(first_name) FROM datatables_demo WHERE first_name LIKE '%".$_GET['term']."%' LIMIT {$pageStart},{$pageEnd}")->fetchColumn();;
$stmt->execute();
$json = [];
while($row = $stmt->fetch(PDO::FETCH_ASSOC)){
$json[] = ['id'=>$row['id'], 'username'=>$row['first_name']];
}
$endCount = $pageStart + $pageLength;
$morePages = $endCount > $count;
$results = array(
"results" => $json,
"pagination" => array(
"more" => $morePages
)
);
echo json_encode($results);
}
catch(PDOException $e){
echo $e->getMessage();
}
Found not much examples about select2 paginate, had to figure it out on my own and here is the full working of how to paginate data(infinite scroll) using Select2: Hope this helps someone else.
JS:
$('#compose_username').select2({
dropdownParent: $("#modal-compose") ,
placeholder: "Search Username...",
minimumInputLength: 1,
allowClear: true,
ajax: {
url: "username.php",
dataType: 'json',
delay: 250,
cache: false,
data: function (params) {
return {
term: params.term,
page: params.page || 1,
};
},
processResults: function(data, params) {
//console.log(data);
// NO NEED TO PARSE DATA `processResults` automatically parse it
//var c = JSON.parse(data);
console.log(data);
var page = params.page || 1;
return {
results: $.map(data, function (item) { return {id: item.col, text: item.col}}),
pagination: {
// THE `10` SHOULD BE SAME AS `$resultCount FROM PHP, it is the number of records to fetch from table`
more: (page * 10) <= data[0].total_count
}
};
},
}
});
PHP(USING PDO):
try{
$page= $_GET['page'];
$resultCount = 10;
$end = ($page - 1) * $resultCount;
$start = $end + $resultCount;
$stmt = $db_con->query("SELECT col,col FROM table WHERE col LIKE '".$_GET['term']."%' LIMIT {$end},{$start}");
$stmt->execute();
$count = $stmt->rowCount();
$data = [];
while($row = $stmt->fetch(PDO::FETCH_ASSOC))
$data[] = ['id'=>$row['id'], 'col'=>$row['col'],'total_count'=>$count];
// IF SEARCH TERM IS NOT FOUND DATA WILL BE EMPTY SO
if (empty($data)){
$empty[] = ['id'=>'', 'col'=>'', 'total_count'=>''];
echo json_encode($empty);
}
else
echo json_encode($data);
}
catch(PDOException $e){
echo $e->getMessage();
}

jquery sortable saving to database not working properly

I'm trying to incorporate the jquery sortable functionality into my website and saving the positions in the database is giving me all sorts of headaches... I've been fighting this for 3 days now, and I cannot seem to get this work properly.
As it stands, it is saving positions to the database, but not in the order or positions, that you'd expect. Meaning, if I move the item in position 0 to position 1, it saves the positions in a different order in the db. check out a live version here.
Here is my code...
index.php file:
<div id="container">
<?php
require_once 'conn.php';
$q = ' SELECT * FROM items WHERE groupId = 3 ORDER BY position ';
$result = mysqli_query($db, $q);
if ($result->num_rows > 0) {
while($items = $result->fetch_assoc()) {
?>
<div id='sort_<?php echo$items['position'] ?>' class='items'>
<span>☰</span> <?php echo$items['description'] ?>
</div>
<?php
}
}
?>
</div>
js.js file:
$("#container").sortable({
opacity: 0.325,
tolerance: 'pointer',
cursor: 'move',
update: function(event, ui) {
var itId = 3;
var post = $(this).sortable('serialize');
$.ajax({
type: 'POST',
url: 'save.php',
data: {positions: post, id: itId },
dataType: 'json',
cache: false,
success: function(output) {
// console.log('success -> ' + output);
},
error: function(output) {
// console.log('fail -> ' + output);
}
});
}
});
$("#container").disableSelection();
save.php file:
require_once('conn.php');
$itId = $_POST['id'];
$orderArr = $_POST['positions'];
$arr = array();
$orderArr = parse_str($orderArr, $arr);
$combine = implode(', ', $arr['sort']);
$getIds = "SELECT id FROM items WHERE groupId = '$itId' ";
$result = mysqli_query($db, $getIds);
foreach($arr['sort'] as $a) {
$row = $result->fetch_assoc();
$sql = " UPDATE items
SET position = '$a'
WHERE id = '{$row['id']}' ";
mysqli_query($db, $sql);
}
echo json_encode( ($arr['sort']) );
Can anyone please point to where I am going wrong on this?
Thank you in advance.
Serge
In case someone lands on here, here is what worked in my case...
NOTE: I did not create prepared statements in the index.php select function. But you probably should.
index.php file:
<div id="container">
<?php
require_once 'conn.php';
$q = ' SELECT * FROM items WHERE groupId = 3 ORDER BY position ';
$result = mysqli_query($db, $q);
if ($result->num_rows > 0) {
while( $items = $result->fetch_assoc() ){
?>
<div id='sort_<?php echo $items['id'] ?>' class='items'>
<span>☰</span> <?php echo $items['description'] ?>
</div>
<?php
}
}
?>
</div>
jquery sortable file:
var ul_sortable = $('#container');
ul_sortable.sortable({
opacity: 0.325,
tolerance: 'pointer',
cursor: 'move',
update: function(event, ui) {
var post = ul_sortable.sortable('serialize');
$.ajax({
type: 'POST',
url: 'save.php',
data: post,
dataType: 'json',
cache: false,
success: function(output) {
console.log('success -> ' + output);
},
error: function(output) {
console.log('fail -> ' + output);
}
});
}
});
ul_sortable.disableSelection();
update php file:
$isNum = false;
foreach( $_POST['sort'] as $key => $value ) {
if ( ctype_digit($value) ) {
$isNum = true;
} else {
$isNum = false;
}
}
if( isset($_POST) && $isNum == true ){
require_once('conn.php');
$orderArr = $_POST['sort'];
$order = 0;
if ($stmt = $db->prepare(" UPDATE items SET position = ? WHERE id=? ")) {
foreach ( $orderArr as $item) {
$stmt->bind_param("ii", $order, $item);
$stmt->execute();
$order++;
}
$stmt->close();
}
echo json_encode( $orderArr );
$db->close();
}
Change your JS code like this:
{...}
tolerance: 'pointer',
cursor: 'move',
// new LINE
items: '.items', // <---- this is the new line
update: function(event, ui) {
var itId = 3;
var post = $(this).sortable('serialize'); // it could be removed
// new LINES start
var post={},count=0;
$(this).children('.items').each(function(){
post[++count]=$(this).attr('id');
});
// new LINES end
$.ajax({
{...}
With this $.each loop you overwrite your var post -> serialize and define your own sort order. Now look at your $_POST["positions"] with PHP print_r($_POST["positions"]); and you have your positions in your own order.

Here is changed js function
<script>
function checkemail() {
var status = document.getElementById("emailudahada");
var u = document.getElementById("email").value;
if (u != "") {
document.getElementById("email").style.backgroundColor = "yellow";
status.innerHTML = "<img src='/img/loading.GIF'></img>";
$.ajax({
url: '/ztest2.php',
type: "POST",
dataType: "json", //need to tell that response will as json
data: ({
email: u,
cekemailsignup: 'yes'
}),
success: function(result) {
status.innerHTML = result.result + "," + result.cekemailsignup. + "," + result.email;
}
});
} else {
document.getElementById("email").style.backgroundColor = "white";
}
}
</script>
result is string, to use it like object you need to parse it to JSON.
var obj = JSON.parse(result);
You can also set dataType: 'json', in the $.ajax configuration options to set it by default and then you don't need to parse the response, it can be directly used.
As jQuery is included on page, use it for DOM manipulation.
Complete Code:
$('#email').on('blur', function() {
var $status = $('#emailudahada');
email = $.trim($(this).val());
if (email) {
$(this).css('backgroundColor', 'yellow');
$status.html('<img src=\'/img/loading.GIF\'></img>');
$.ajax({
url: '/ztest2.php',
type: 'POST',
dataType: 'json',
data: ({
email: email,
cekemailsignup: 'yes'
}),
success: function(result) {
$status.html(result.result + ',' + result.cekemailsignup. + ',' + result.email);
}
});
} else {
$(this).css('backgroundColor', 'white');
}
});
