I want to off the click when the First Page and Previous li is disabled also when you are on last page the Next and Last should be not clicked. I used off() and unbind() it is working to off the click but when the li is enabled then the click is not working. You can check it here on this link my project is live here http://199.192.21.232/~admin/category.php?cat_id=2 thank you.

Ajax based range search in jquery plugin "Datatables"

I´m using the jquery based table plugin "datatables" and I´m trying to implement an ajax based "range search" between two numbers ("start-date" and "end_date"). These entered values should be used for a query in the MySQL column "order_id".
On the server-sided script (fetch.php) I catch the both values like that.
if(isset($_POST['start_date'], $_POST['end_date'])) {
$query .= 'order_id BETWEEN "'.$_POST["start_date"].'" AND "'.$_POST["end_date"].'" AND ';
}
The problem is I can´t see any errors in the console, but after using the number range search no results are displayed.
The "category select menus" (category and category2) are working as expected.
I´ve setted up a test site, maybe you can help me to find the error: Testsite
This is my script:
$(document).ready(function () {
var category = "";
var category2 = "";
var start_date = "";
var end_date = "";
load_data();
function load_data(is_category, is_category2, start_date, end_date) {
console.log(is_category, is_category2, start_date, end_date);
var dataTable = $('#product_data').DataTable({
"processing": true,
"serverSide": true,
"order": [],
"ajax": {
url: "fetch.php",
type: "POST",
data: {
is_category: is_category,
is_category2: is_category2,
start_date: start_date,
end_date: end_date
},
}
});
}
// Number Range Search
$('#search').click(function () {
console.log($(this).attr('id'), start_date, end_date)
var start_date = $('#start_date').val();
var end_date = $('#end_date').val();
if (start_date != '' && end_date != '') {
$('#product_data').DataTable().destroy();
load_data('','',start_date, end_date);
}
else {
alert("Both Date is Required");
}
});
// Select Menu id="category"
$(document).on('change', '#category, #category2', function () {
//console.log($(this).attr('id'), category, category2)
if ($(this).attr('id') === "category") {
category = $(this).val();
} else if ($(this).attr('id') === "category2") {
category2 = $(this).val();
}
//
$('#product_data').DataTable().destroy();
if (category != '') {
load_data(category, category2);
}
else {
load_data();
}
});
// Select Menu id="category2"
$(document).on('change', '#category2', function () {
var category2 = $(this).val();
$('#product_data').DataTable().destroy();
if (category2 != '') {
load_data(category, category2);
}
else {

OR order_value LIKE "%'.$_POST["search"]["value"].'%")
';
}
if(isset($_POST["order"]))
{

';
}
else
{

$result = mysqli_query($connect, $query . $query1);
$data = array();
while($row = mysqli_fetch_array($result))
{
$sub_array = array();
$sub_array[] = $row["order_id"];
$sub_array[] = $row["order_customer_name"];
$sub_array[] = $row["order_item"];
$sub_array[] = $row["order_value"];
$sub_array[] = $row["order_date"];
$data[] = $sub_array;
}
function get_all_data($connect)
{
$query = "SELECT * FROM tbl_order";
$result = mysqli_query($connect, $query);
return mysqli_num_rows($result);
}
$output = array(
"draw" => intval($_POST["draw"]),
"recordsTotal" => get_all_data($connect),
"recordsFiltered" => $number_filter_row,
"data" => $data
);
echo json_encode($output);

Thats because the is_category and is_category2 are returning 0. You have probably an if statement on your php like if $_POST[is_category] but you also need to do the same in case there is no category selected. Please share the full php to help you out
on your click function replace load_data(start_date, end_date); with load_data('','',start_date, end_date);

jquery select2 - Format the results via AJAX php

i use select2, i want to format my results like
name, first.
$("#id").select2({
minimumInputLength : 0,
allowClear: true,
ajax : {
url : "Form/page.php",
dataType : 'json',
data : function (term, page) {
return {
q : term
};
},
results: function (data, page) {
return { results : data.ex};
},
formatResult : function formatResult(ex) {
return '<b>' + ex.name + '</b>';
}
}
});
my php file like
while($r=mysql_fetch_array($m)) {
$rows['id']=$r['id'];
$rows['text']=$r['name'];
$rows['first']=", ". $r['first'];
$rows2[]=$rows;
}
print json_encode($rows2);
how can i do that, thanks

I think the php code has to be like this:
while($r=mysql_fetch_array($m)) {
$rows['id']=$r['id'];
$rows['name']=$r['name'];
$rows['first']=$r['first'];
$rows2[]=$rows;
}
print json_encode($rows2);
So, you pass an array of json objects with an id, name and first.
Change the return of formatResult to:
return '<b>' + ex.name + '</b>, ' + ex.first;

PHP example reposted from the Select2 - source example:
https://github.com/ivaynberg/select2/wiki/PHP-Example
In JS:
$('#categories').select2({
placeholder: 'Search for a category',
ajax: {
url: "/ajax/select2_sample.php",
dataType: 'json',
quietMillis: 100,
data: function (term, page) {
return {
term: term, //search term
page_limit: 10 // page size
};
},
results: function (data, page) {
return { results: data.results };
}
},
initSelection: function(element, callback) {
return $.getJSON("/ajax/select2_sample.php?id=" + (element.val()), null, function(data) {
return callback(data);
});
}
});
and in PHP:
<?php
$row = array();
$return_arr = array();
$row_array = array();
if((isset($_GET['term']) && strlen($_GET['term']) > 0) || (isset($_GET['id']) && is_numeric($_GET['id'])))
{
if(isset($_GET['term']))
{
$getVar = $db->real_escape_string($_GET['term']);
$whereClause = " label LIKE '%" . $getVar ."%' ";
}
elseif(isset($_GET['id']))
{
$whereClause = " categoryId = $getVar ";
}
/* limit with page_limit get */
$limit = intval($_GET['page_limit']);
$sql = "SELECT id, text FROM mytable WHERE $whereClause ORDER BY text LIMIT $limit";
/** #var $result MySQLi_result */
$result = $db->query($sql);
if($result->num_rows > 0)
{
while($row = $result->fetch_array())
{
$row_array['id'] = $row['id'];
$row_array['text'] = utf8_encode($row['text']);
array_push($return_arr,$row_array);
}
}
}
else
{
$row_array['id'] = 0;
$row_array['text'] = utf8_encode('Start Typing....');
array_push($return_arr,$row_array);
}
$ret = array();
/* this is the return for a single result needed by select2 for initSelection */
if(isset($_GET['id']))
{
$ret = $row_array;
}
/* this is the return for a multiple results needed by select2
* Your results in select2 options needs to be data.result
