Cart block not updating codeigniter

I have this controller:
<?php
class Cart extends CI_Controller{
public $paypal_data = '';
public $tax;
public $shipping;
public $total = 0;
public $grand_total;
/*
*Cart Index
*/
public function index(){
//Load view
$data['main_content'] = 'cart';
$this->load->view('layouts/main', $data);
}
/*
*Add To Cart
*/
public function add(){
//Item data
$data = array(
'id'=> $this->input->post('item_number'),
'qty'=> $this->input->post('qty'),
'price'=> $this->input->post('price'),
'name'=> $this->input->post('title'),
);
//print_r($data);die();
//Insert Into cart-block
$this->cart->insert($data);
redirect('products');
}
}
And I have the view file which uses this controller:
<div class="cart-block">
<form action="cart/update" method="post">
<table cellpadding="6" cellspacing="1" style="width:100%" border="0">
<tr>
<th>QTY</th>
<th>Item Description</th>
<th style="text-align:right">Item Price</th>
</tr>
<?php $i = 1; ?>
<?php foreach ($this->cart->contents() as $items) : ?>
<input type="hidden" name="<?php echo $i. '[rowid]'; ?>" value="<?php echo $items['rowid']; ?>" />
<tr>
<td><input type="text" name="<?php echo $i.'[qty]'; ?>" value="<?php echo $items['qty']; ?>" maxlength="3" size= "5"</td>
<td><?php echo $items['name']; ?></td>
<td style="text-align:right"><?php echo $this->cart->format_number($items['price']); ?></td>
</tr>
<?php $i++; ?>
<?php endforeach; ?>
<tr>
<td></td>
<td class="right"><strong>Total</strong></td>
<td class="right" style="text-align:right">$<?php echo $this->cart->format_number($this->cart->total()); ?></td>
</tr>
</table>
<br>
<p><button class="btn btn-default" type="submit">Update Cart</button>
<a class="btn btn-default" href="cart">Go To Cart</a></p>
</form>
</div>
<div class="panel panel-default panel-list">
<div class="panel-heading panel-jeading-dark">
<h3 class="panel-title">
Categories
</h3>
</div>
<!--List group -->
<ul class="list-group">
<?php foreach(get_categories_h() as $category) : ?>
<li class="list-group-item"><?php echo $category->name; ?></li>
<?php endforeach; ?>
</ul>
I apologize that I can't show you the actual website because it's not online but based on the above snippets can any point out an error in the view file or controller that causes the shopping cart not to update?
I'm following a video tutorial but it seems I'm doing something wrong. Here is the video: https://youtu.be/ajt_DJMS5FM?t=13m45s

Your form action is cart/update your function in the controller is add?
Change the form action to cart/add. Or write an cart/update function.

Firstly change the Form Action action="cart/update" to
action="<?php echo base_url();?>cart/add" and apply die(); and test it

load the cart library in controller
$this->load->library('cart');

PHP Looping Javascript Just Show The First Record

I have a view code:
<?php
$i = 1;
//var_dump($this->productList);
foreach ($this->productList as $data) {
$desc=explode(",",$data['descriptions']);
?>
<tr>
<th colspan="3">
<input type="hidden" id="id_pack" name="id_pack" value="<?php echo $data['package_id']; ?>">
<input type="hidden" id="nama_pack" name="nama_pack" value="<?php echo $data['package_name']; ?>">
<h4 align="center" class="title-pack"><?php echo $data['package_name']; ?></h4>
</th>
</tr>
<tr id="dashe">
<td>
<ul class="myul">
<?php foreach($desc as $descriptions) { ?>
<li class="myli"> <?php echo $descriptions; ?></li>
<?php } ?>
</ul>
</td>
<td>
<h4 class="prize">
Rp. <?php echo number_format($data['price'],2);?>
/ month
</h4>
</td>
<td>
<p id="order" name="order" class="mybutton" data-toggle="modal" data-target=".mymodal">Order</p>
</td>
</tr>
<?php
$i++;
}
?>
And this the javascript:
document.getElementById("order").addEventListener("click", tampilkanHrm);
function tampilkanHrm() {
var pilihan=$("#nama_pack").val();
document.getElementById("choice").innerHTML = pilihan;
document.getElementById("pack").value = pilihan+" Package";
}
the problem is, in the order button it always show the same record. Just show the first data, even i clicked other order button. Hope somebody help.

You can't assign same id for multiple elements.
So, have different ids.
<?php
$i = 1;
//var_dump($this->productList);
foreach ($this->productList as $data) {
$desc=explode(",",$data['descriptions']);
?>
<tr>
<th colspan="3">
<input type="hidden" id="id_pack<?php echo $i ?>" name="id_pack" value="<?php echo $data['package_id']; ?>">
<input type="hidden" id="nama_pack<?php echo $i ?>" name="nama_pack" value="<?php echo $data['package_name']; ?>">
<h4 align="center" class="title-pack"><?php echo $data['package_name']; ?></h4>
</th>
</tr>
Similarly create buttons with different ids.
<td>
<p id="<?php echo $i ?>" name="order" class="mybutton" data-toggle="modal" data-target=".mymodal">Order</p>
</td>
Then change your javascript to jquery. Hope, you might also be using jquery [ understood from your code ]
$(".mybutton").on("click", function() {
var identifier = $(this).attr("id");
var pilihan=$("#nama_pack"+identifier).val();
$("#choice").html(pilihan);
});
Change your code like this and check.

Search result on click of button in popup

I want to display search result on click of button, but my code is giving me the search result without click on button.
I think it's giving me the query result not the search result.
This code is working fine when I display the result on the page, but as per my requirement I want to display the search result on a popup.
I have used jquery popup.
<body><form action="#" method="POST"><body><form action="#" method="POST"><div data-role="page">

This will give you search results in modal popup. I have changed your code around a bit. You can popup in case of no search results too.

Disable bootstrap input button if checkbox not checked

My check box when unchecked my input with id of delete should be disabled, but for some reason the java script code it not picking up the id of both input and checked input. I use bootstrap 3 and codeigniter.
What's wrong with my code? Unsure why not working. All JS scripts loaded correct.
<script type="text/javascript">
$('#check_delete').click(function(){
if($(this).attr('checked') == false){
$('input #delete').attr("disabled","disabled");

</script>

You declare your script before the HTML code.
A HTML page is read sequentially.
alert( $('input#delete').length )
<input id="delete" >
This will alert "0" because jQuery looks for #delete, and then, next line, #delete exists.
Two solutions :
1) Move your script after HTML, at the end, before the </body> tag.
2) Wrap your code in $(function(){ /* Your code here */ } . This will wait for the page to be ready before executing the script.
<input id="delete" >
alert( $('input#delete').length )
This will work, and this also will :
$(function(){
alert( $('input#delete').length )
})
<input id="delete" >
