Hello everyone,

 

I have a cart file in which i want to make a remove button, which is display beside every items.

 

Here is the code for cart.php

 

 

<?php
session_start();

ini_set('display_errors', 1);
error_reporting(0);

require_once 'settings/config.php';


define("PRODUCTCODE", 0);
define("PRODUCTNAME", 1);
define("QUANTITY", 2);
define("PRICE", 3);



if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
  if (isset($_POST['productcode']))
  {
  AddToCart();
  }
  else
  {
  $action = isset($_POST['action']) ? $_POST['action'] : '';
  $value = trim($action);
  switch ($value)
  {
  // continue shopping
  case $continue_label:
	 header("Location: ".$shopping_url);
	 break;

  // recalculate
  case $recalculate_label:
	 RecalculateCart();
	 break;

  // proceed to checkout
  case $checkout_label:
	 header("Location: ".$cart_redirect);
	 break;
  }
  }
}


function AddToCart()
{
  $cart = isset($_SESSION['cart']) ? $_SESSION['cart'] : '';
  $itemcount = isset($_SESSION['itemcount']) ? $_SESSION['itemcount'] : 0;

$productname = $_POST['productname'];
$extra_price = 0;
for ($opt = 1; $opt <= 8; $opt++){
$key = 'option_name'.$opt;
$key1 = 'option_values'.$opt;
$option_name = trim($_POST[$key]);
$option_value = trim($_POST[$key1]);

if ($option_value != "") {
unset($options);
$options = explode(",", $option_value);
$productname .= " / $option_name : ".$options[0];
$extra_price = $extra_price + $options[1];
}
}
$productname = stripslashes($productname);

// Let's see if this product already exists
  for ($i=0; $i < $itemcount; $i++)
  {
 if ($cart[PRODUCTNAME][$i] == $productname) {
	 $cart[QUANTITY][$i] = $cart[QUANTITY][$i] + intval($_POST['quantity']);
	 $_SESSION['cart'] = $cart;
	 $_SESSION['itemcount'] = $itemcount;
	 header("Location: "."cart.php");
	 exit;
  }
  }

$cart[PRODUCTCODE][$itemcount] = $_POST['productcode'];
$cart[PRODUCTNAME][$itemcount] = stripslashes($productname);
$cart[QUANTITY][$itemcount] = intval($_POST['quantity']);
$cart[PRICE][$itemcount] = $_POST['price'] + $extra_price;

  $itemcount = $itemcount + 1;

  $_SESSION['cart'] = $cart;
  $_SESSION['itemcount'] = $itemcount;
}

function RecalculateCart()
{
  include 'settings/config.php';

  $cart = isset($_SESSION['cart']) ? $_SESSION['cart'] : '';
  $itemcount = isset($_SESSION['itemcount']) ? $_SESSION['itemcount'] : 0;

  for ($i=0; $i<$itemcount; $i++)
  {
  $quantity = $_POST['quantity'.($i)];
  if (empty($quantity))
  {
	 $quantity = 0;
  }
  else
  if (($quantity <= 0) || (!is_numeric($quantity)))
  {
	 $quantity = 0;
  }
  $cart[QUANTITY][$i] = intval($quantity);
  }

  for ($j=0; $j<$itemcount; $j++)
  {
  $quantity = $cart[QUANTITY][$j];

  // remove item from the cart
  if ($quantity == 0)
  {
	 $itemcount--;

	 $curitem = $j;

	 while(($curitem+1) < count($cart[0]))
	 {
	    for ($k=0; $k<7; $k++)
	    {
		   $cart[$k][$curitem] = $cart[$k][$curitem+1];
		   $cart[$k][$curitem+1] = '';
	    }
	    $curitem++;
	 }
  }
  }
  $_SESSION['itemcount'] = $itemcount;
  $_SESSION['cart'] = $cart;
 }
?>

What part are you having trouble with?

 

If you see here.....

 

$strHTML .= '<tr>';
	 $strHTML .= '<td align="center" bgcolor="'.$BGCOLOR.'"><font style="font-size:'.$CELL_TEXT_SIZE.'px" color="'.$CELL_TEXT_CLR.'" face="'.$CELL_TEXT_FONT.'"><'.$CELL_TEXT_STYLE.'>'.$cart[PRODUCTCODE][$i].'</'.$CELL_TEXT_STYLE.'></font></td>';
	 $strHTML .= '<td align="left" bgcolor="'.$BGCOLOR.'"><font style="font-size:'.$CELL_TEXT_SIZE.'px" color="'.$CELL_TEXT_CLR.'" face="'.$CELL_TEXT_FONT.'"><'.$CELL_TEXT_STYLE.'>'.$cart[PRODUCTNAME][$i].'</'.$CELL_TEXT_STYLE.'></font></td>';
	 $strHTML .= '<td align="center" bgcolor="'.$BGCOLOR.'"><input type="text" name="quantity'.($i).'" style="text-align:right;width:40px;font-family:'.$CELL_TEXT_FONT.';font-size:'.$CELL_TEXT_SIZE.'px" align="right" value="'.$cart[QUANTITY][$i].'" size="1"></td>';
	 $strHTML .= '<td align="center" bgcolor="'.$BGCOLOR.'"><font style="font-size:'.$CELL_TEXT_SIZE.'px" color="'.$CELL_TEXT_CLR.'" face="'.$CELL_TEXT_FONT.'"><'.$CELL_TEXT_STYLE.'>'.number_format($cart[PRICE][$i],2).'</'.$CELL_TEXT_STYLE.'></font></td>';
	 $strHTML .= '<td align="right" bgcolor="'.$BGCOLOR.'"><font style="font-size:'.$CELL_TEXT_SIZE.'px" color="'.$CELL_TEXT_CLR.'" face="'.$CELL_TEXT_FONT.'"><'.$CELL_TEXT_STYLE.'>'.number_format($cart[PRICE][$i]*$cart[QUANTITY][$i],2).'</'.$CELL_TEXT_STYLE.'></font></td>';
	 $strHTML .= '</tr>';

 

This is the display table for showing product details.....

 

 

Now this code remove product from cart when the quantity set to zero and recalculate button is pressed

 

if ($quantity == 0)
	 {
			 $itemcount--;

			 $curitem = $j;

			 while(($curitem+1) < count($cart[0]))
			 {
				 for ($k=0; $k<7; $k++)
				 {
					 $cart[$k][$curitem] = $cart[$k][$curitem+1];
					 $cart[$k][$curitem+1] = '';
				 }
				 $curitem++;
			 }
	 }

 

now i add one extra button with each product code like this

$strHTML .= '<td align="center" bgcolor="'.$BGCOLOR.'"><font style="font-size:'.$CELL_TEXT_SIZE.'px" color="'.$CELL_TEXT_CLR.'" face="'.$CELL_TEXT_FONT.'"><'.$CELL_TEXT_STYLE.'>'.$cart[PRODUCTCODE][$i].'

<input name="deleteBtn' .$cart[PRODUCTCODE]. '" type="submit" value="remove" />

</'.$CELL_TEXT_STYLE.'></font></td>';

 

 

now i want to make isset statement or maybe other for this input field

 

that if someone click this remove button then that item will be removed.....
