Hello, i not sure what is the problem with my code. Below is my code.
<?php
if(isset($_SESSION["products"]) && count($_SESSION["products"])>0){
$total = 0;
foreach($_SESSION["products"] as $product){
$product_name = $product["name"];
$product_price = $product["price"];
$product_code = $product["product_code"];
$product_qty = $product["product_qty"];
$currency = "RM ";
$img = mysqli_query($link, "SELECT img FROM internet_shop where id=$product_code");
$row = mysqli_fetch_assoc($img);
$item_price = sprintf("%01.2f",($product_price)); // price x qty = total item price
$subtotal = sprintf("%01.2f",($product_price * $product_qty)); //Multiply item quantity * price
$total = sprintf("%01.2f",($total + $subtotal)); //Add up to total price
?>
<tr>
<form id="update_info_cart<?php echo $product_code?>" class="form-horizontal form-label-left">
<input name="update" type="hidden" value="update">
<td><img src="<?php echo "adminPanel/MenuPicture/".$row['img']?>" alt="<?php echo $product_name ?>"></td>
<td colspan="2"><?php echo $product_name ?></td>
<td><input type="number" value="<?php echo $product_qty ?>" name="product_qty" class="form-control" min="1" max="5"></td>
<td><?php echo $currency. $item_price?></td>
<td><?php echo $currency. $subtotal?></td>
<td><a class="update-item<?php echo $product_code?>"><i class="fa fa-refresh"></i></a> </td>
<script>
$(document).ready(function(){
$('a.update-item'+<?php echo $product_code?>).click(function(e) {
var form_data = $('#update_info_cart'+<?php echo $product_code?>).serialize();
/*$.ajax({ //make ajax request to cart_process.php
url: "update_cart_process.php",
type: "POST",
dataType:"json", //expect json value from server
data: form_data
}).done(function(data){ //on Ajax success
alert(<?php echo $product_code?>);
})
e.preventDefault();*/
alert(form_data);
});
});
</script>
<td><a class="remove-item" data-code="<?php echo $product_code?>"><i class="fa fa-trash-o"></i></a> </td>
</form>
</tr>
<?php
}
