pagination not appearing in php

i have a table in php whose data comes from sql database, so i have kept a pagination for the table because the data is long
<?php
require_once "config.php";
$perpage = 5;
if(isset($_GET['page']) & !empty($_GET['page'])){
$curpage = $_GET['page'];
}else{
$curpage = 1;
}
$start = ($curpage * $perpage) - $perpage;
$sql = "SELECT * FROM `registers` LIMIT $start, $perpage";
$PageSql = "SELECT * FROM `registers`";
$pageres = mysqli_query($link, $PageSql);
$totalres = mysqli_num_rows($pageres);
if($result = mysqli_query($link, $sql)){
if(mysqli_num_rows($result) > 0){
echo "<table class='table'>";
echo "<thead>";
echo "<tr>";
echo "<th class='serial'>ID</th>";
echo "<th>Name</th>";
echo "<th>Phone Number</th>";
echo "<th>Email</th>";
echo "<th>Action</th>";
echo "</tr>";
echo "</thead>";
echo "<tbody>";
while($row = mysqli_fetch_array($result)){
echo "<tr>";
echo "<td>" . $row['id'] . "</td>";
echo "<td>" . $row['firstname'] . "</td>";
echo "<td>" . $row['address'] . "</td>";
echo "<td>" . $row['id'] . "</td>";
echo "<td>";
echo "<a href='read.php?id=". $row['id'] ."' title='View Record' data-toggle='tooltip'><span class='glyphicon glyphicon-eye-open'></span></a>";
echo "</td>";
echo "</tr>";
}
echo "</tbody>";
echo "</table>";
// Free result set
mysqli_free_result($result);
} else{
echo "<p class='lead'><em>No records were found.</em></p>";
}
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
?>
<nav aria-label="Page navigation">
<ul class="pagination">
<?php if($curpage != $startpage){ ?>
<li class="page-item">
<a class="page-link" href="?page=<?php echo $startpage ?>" tabindex="-1" aria-label="Previous">
<span aria-hidden="true">«</span>
<span class="sr-only">First</span>
</a>
</li>
<?php } ?>
<?php if($curpage >= 2){ ?>
<li class="page-item"><a class="page-link" href="?page=<?php echo $previouspage ?>"><?php echo $previouspage ?></a></li>
<?php } ?>
<li class="page-item active"><a class="page-link" href="?page=<?php echo $curpage ?>"><?php echo $curpage ?></a></li>
<?php if($curpage != $endpage){ ?>
<li class="page-item"><a class="page-link" href="?page=<?php echo $nextpage ?>"><?php echo $nextpage ?></a></li>
<li class="page-item">
<a class="page-link" href="?page=<?php echo $endpage ?>" aria-label="Next">
<span aria-hidden="true">»</span>
<span class="sr-only">Last</span>
</a>
</li>
<?php } ?>
</ul>
</nav>
<?php }?>
the data is correctly added into the database, but the problem is the pagination is nowhere seen in the page. when i just put the html it was coming,but when i added the php code inside it,its is not coming. can anyone tell me what could be the problem please?

Move <nav></nav> code inside
if(mysqli_num_rows($result) > 0){ }
Before or after your table.
Issue is that you now show it only if your if statement fails: if($result = mysqli_query($link, $sql)){ } else { }

how to write javascript which create fixedheader for each table separately

There is a self-written website on WordPress tarifes. I made a script that searches for each copy of the thead table and makes it fixed to the fixed_table_header table, but here's the problem when the same shortcode makes a new table for each one and the same thead, help you figure out how to add or change the script so that the header was fixed for each table separately
<?php
/*====================================================SHORTCODES EXEL=========================================================*/
public function show_mps_excel($atts){
$atts = shortcode_atts( array(
'name' => 'express_import',
'sheet' => 0,
'class' => '',
), $atts );
extract($atts);
?>
<?php $mps_option = get_option('gamma_mps'); ?>
<?php if(isset($mps_option[$name]['sheet'.$sheet])): ?>
<?php ob_start(); ?>
<div class="container-fluid block-content">
<div class="row">
<div class="col-sm-12 col-md-12 col-lg-12 welcome-text">
<!-- <table class="table table-hover table-bordered taxes" style="margin-top: -25px"> -->
<?php if($name != 'zones'): ?>
<?php $this->full_table($mps_option, $name, $sheet, $class); ?>
<?php else: ?>
<?php $this->half_table($mps_option, $name, $sheet, $class, 0, 118); ?>
<?php $this->half_table($mps_option, $name, $sheet, $class, 117, 234); ?>
<?php endif; ?>
<?php if(false): ?>
<h5>Загрузить таблицу в .XLSX: <a class="btn btn-success" href="<?php echo $mps_option[$name]['download_url']; ?>">Загрузить</a></h5>
<?php endif; ?>
</div>
</div>
</div>
<?php $html = ob_get_clean(); ?>

(function($) {
$(document).ready(function() {
var table = $('table'),
thead = table.find('thead'),
fixed_thead,
fixed_table = $('<table />', {
'cellpadding': 5,
'cellspacing': 0,
'border': 1,
'id': 'fixed_table_header'
}),
fixed_table_wrapper = $('<div />', {
'height': 400,
'css': {
'overflow': 'auto'
}
});
table.before(fixed_table);
thead.find('td').each(function() {
$(this).css('width', $(this).width());
});
fixed_thead = thead.clone();
fixed_table.append(fixed_thead);
thead.hide();
table.wrap(fixed_table_wrapper);
// align the new table header with the original table
fixed_table.css('left', (fixed_table.offset().left - table.offset().left) * -1);
});
})(jQuery);

If I understand your question correctly, you target only the first table by using var table = $('table'),. You need to run the manipulation on each table so your code should look something like:
(function($) {
$(document).ready(function() {
$('table').each(function() {
var table = $(this),
thead = table.find('thead'),
fixed_thead,
fixed_table = $('<table />', {
'cellpadding': 5,
'cellspacing': 0,
'border': 1,
'id': 'fixed_table_header'
}),
fixed_table_wrapper = $('<div />', {
'height': 400,
'css': {
'overflow': 'auto'
}
});
table.before(fixed_table);
thead.find('td').each(function() {
$(this).css('width', $(this).width());
});
fixed_thead = thead.clone();
fixed_table.append(fixed_thead);
thead.hide();
table.wrap(fixed_table_wrapper);
// align the new table header with the original table
fixed_table.css('left', (fixed_table.offset().left - table.offset().left) * -1);
});
});
})(jQuery);
This case is similar to the way a jQuery plugin should be written and the solution is similar too: https://learn.jquery.com/plugins/basic-plugin-creation/#using-the-each-method

Updating quantity in cart table

I want that update button should be in that field which I choose.But it appears only in first row and is updating for first row quantity field.
<form action="cart.php?action=update" method="post">

while($row = mysqli_fetch_array($result))
{

and cart2.php
<?php
function deletecart($cartid)
{
include 'connection.php';
$sql1="delete from cart where cart_id=$cartid";
$executequery = mysqli_query($con,$sql1);
header('location:cart.php');

// update product quantity
$sql = "UPDATE cart

For row onw everything is fine.But for row2 update button appears in row1 and not updating at all.

<input tpe="text" name="newqty" value="<?php echo $qty = $row['quantity']; ?>" onkeypress="showsubmit(<?php echo $row['cart_id'] ?>)">

id="sub_<?php echo $row['cart_id'] ?>"
value="UPDATE">
<script>
function showsubmit(id)
{
document.getElementById("sub_"+id).style.visibility ="visible";
}

How should I apply this code to ajax?
Thanks for the help.

it's not necessary to use "success:"
However if you want to check error or debug
1) press F12 on Browser to open Developer Mode
2) do action (add cart)
3) on tab "Network" find your ajax request and see your error

Modify your add() function as follows:
function add(){
$insert_data = array('k1' => 'v1', 'k2' => 'v2');
$success = $this->cart->insert($insert_data);
if($success){
$res = array('status' => 200, 'msg' => 'success', 'somekey' => 'somevalue');
}else{
$res = array('status' => 500, 'msg' => 'database err');
}
echo json_encode($res);
}
Now the add() function has responded the ajax request with some json-formated data, you can parse the response data in javascript. The (success:) function should be like this:
function(response) {
if (response){
var res = JSON.parse(response);
if(res.status == 200){
window.location.href="http://127.0.0.1/codeigniter_cart2/index.php/shopping";
}else{
//error handler
alert(res.msg);
}
}else{
alert('sorry');
}
});

function __construct(){
parent::__construct();
$this->load->library(array('session','cart'));
$this->load->library('');
$this->load->helper('url');
$this->load->database();
}
public function product_list(){
$this->db->select('*');
$this->db->from('product');
$this->db->order_by('product_id','desc');
$rs = $this->db->get();
return $rs->result_array();
}
public function product_byId($pid){
$this->db->select('*');
$this->db->from('product');
$this->db->where('product_id',$pid);
$rs = $this->db->get();
return $rs->row_array();
}

Add Variable from PHP foreach to bootstrap modal

I have a button within a php foreach statement which loads a modal. How can i pass the particular id ($animalid) to the modal? I have it kind of working but the modal will load the same id in each modal popup. See my php foreach code below and also part of the modal.
$pdo2 = Database::connect();
$sql2 = 'SELECT * FROM animals WHERE riderid = '.$data[id].' AND hp != "Choose One"';
foreach ($pdo2->query($sql2) as $row) {
echo '<tr>';
echo '<td>'. $row['hp'] . '</td>';
echo '<td>'. $row['hpname'] . '</td>';
echo '<td>'. $row['hpage'] . '</td>';
echo '<td>'. $row['hpcolour'] . '</td>';
echo '<td>'. $row['hpmicro'] . '</td>';
echo '<td>';
echo '<button class="btn btn-default btn-xs" id="float-right" data-toggle="modal" data-target=".bs-example-modal-lg-2"><span class="glyphicon glyphicon-pencil"></span> Update</button>';
echo ' ';
echo '<a class="btn btn-default btn-xs" href="#"><span class="glyphicon glyphicon-trash"></span> Delete</a>';
echo '</td>';
echo '</tr>';
$animalid = $row['id'];
}
Database::disconnect();
?>
Modal Code
<div class="modal-body">
<form name="editanimal" id="editanimal" class="form-horizontal" action="updateanimal.php" method="post">
<span class="form-break">
<?php
// Get Animal id
//$animalid = $data['id'];
echo $animalid;
?>

$animalid is in the loop. If you want to use that value, you can store the data to other array and use it. Hope you get some inspiration.
PHP:
<?php
$pdo2 = Database::connect();
$sql2 = 'SELECT * FROM animals WHERE riderid = '.$data[id].' AND hp != "Choose One"';
$list = array();
foreach ($pdo2->query($sql2) as $row) {
$item = array();
$content = '<tr>';
$content .= '<td>'. $row['hp'] . '</td>';
$content .= '<td>'. $row['hpname'] . '</td>';
$content .= '<td>'. $row['hpage'] . '</td>';
$content .= '<td>'. $row['hpcolour'] . '</td>';
$content .= '<td>'. $row['hpmicro'] . '</td>';
$content .= '<td>';
$content .= '<button class="btn btn-default btn-xs" id="float-right" data-toggle="modal" data-target=".bs-example-modal-lg-2"><span class="glyphicon glyphicon-pencil"></span> Update</button>';
$content .= ' ';
$content .= '<a class="btn btn-default btn-xs" href="#"><span class="glyphicon glyphicon-trash"></span> Delete</a>';
$content .= '</td>';
$content .= '</tr>';
$item['id'] = $row['id'];
$item['content'] = $content;
$list[] = $item;
}
Database::disconnect();
?>
HTML:
<div class="modal-body">
<form name="editanimal" id="editanimal" class="form-horizontal" action="updateanimal.php" method="post">
<span class="form-break"></span>
<?php foreach($list as $item){ ?>
<?php echo $item['id'];?>
<?php } ?>
or..
<table>
<?php foreach($list as $item){ ?>
<?php echo $item['content'];?>
<?php } ?>
</table>
<!-- ... -->
</form>
</div>

$animalid is being over written each time you iterate through the foreach loop. You would have to build an array to hold all of the animalids, and pass that to your modal or print out the id as you are iterating through the loop.
