[SOLVED] How to delete items from this cart?

[phpdragon]

Hi

 

I would like to know how to delete items from this cart if $itemqty is set to 0, at present it modifies the cart item quantities by entering a number in a form and hitting order to update this cart, I would like it to delete the item from the cart if the quantity is set to 0.

Any help appreciated tku.

 

here is my code for creating the cart

 

<?php
$basket = $_POST['basket'];
$itemprice = $_POST['price'];
$id = $_POST['id'];
$itemqty = $_POST['quantity'];
if (($basket!="") && (!empty($_POST['submit']))){
   	if (session_is_registered("ses_basket_items")){
	$basket_position_counter=0;
	$double=0;
	if ($ses_basket_items>0){
	   foreach ($ses_basket_name as $basket_item){
	      if ($basket_item==$basket){
	         $double=1;
	         $basket_position=$basket_position_counter;
	      }
	      $basket_position_counter++;
	   }
	}
	if ($double==1){
	   $ses_basket_amount[$basket_position]=$itemqty;
	   $newprice=$itemprice*$itemqty;
	   $ses_basket_price[$basket_position]=$newprice;
	}else{
	   $ses_basket_name[]=$basket;
	   $ses_basket_amount[]=$itemqty;
	   $ses_basket_price[]=$itemprice;
	   $ses_basket_id[]=$id;
	   $ses_basket_items++;
	}
}else{
	$ses_basket_items=1;
	$ses_basket_name[0]=$basket;
	$ses_basket_amount[0]=$itemqty;
	$ses_basket_price[0]=$itemprice;
	$ses_basket_id[0]=$id;
	session_register("ses_basket_items");
	session_register("ses_basket_name");
	session_register("ses_basket_amount");
	session_register("ses_basket_price");
	session_register("ses_basket_id");
}
}

if ($ses_basket_items>0){
  
  echo "<table cellpadding='0' cellspacing='0' border='0' width='230'><tr><td class='carthead'>ITEM</td><td align='center' class='carthead'>QTY</td><td class='carthead' align='right'>TOTALS </td></tr>";
   for ($basket_counter=0;$basket_counter<$ses_basket_items;$basket_counter++){
      $price=sprintf("%01.2f",$ses_basket_price[$basket_counter]);
      $quantity=$ses_basket_amount[$basket_counter];
      $name=$ses_basket_name[$basket_counter];
      echo "<tr><td width='130px' align='left' class='cart'>$name</td><td width='50px' align='center' class='cart'>$quantity</td><td width='50px' class='cart' align='right'>\$$price </td></tr>";
   }  
   $totalprice=sprintf("%01.2f",array_sum($ses_basket_price));
   $totalitems=array_sum($ses_basket_amount);
   echo "<tr><td align='left' class='cartbot'>CURRENT TOTALS:</td><td align='center' class='cartbot'>$totalitems</td><td align='right' class='cartbot'>\$$totalprice </td></tr></table>";
} else {
$ses_basket_items=0;
unset($ses_basket_name);
unset($ses_basket_amount);
unset($ses_basket_price);
unset($ses_basket_id);
}
?>

For those who want to know here is the code

 

// Delete Item when set to 0
if ($itemqty == "0") {
	array_splice ($ses_basket_name, $basket_position, 1);
	array_splice ($ses_basket_amount, $basket_position, 1);
	array_splice ($ses_basket_price, $basket_position, 1);
	array_splice ($ses_basket_id, $basket_position, 1);
	$ses_basket_items--;
}

 

and here is the code in the page, placement is important

 

<?php
$basket = $_POST['basket'];
$itemprice = $_POST['price'];
$id = $_POST['id'];
$sub = $_POST['submit'];
$itemqty = $_POST['quantity'];
if (($basket!="") && (!empty($_POST['submit']))){
   	if (session_is_registered("ses_basket_items")){
	$basket_position_counter=0;
	$double=0;
	if ($ses_basket_items>0){
	   foreach ($ses_basket_name as $basket_item){
	      if ($basket_item==$basket){
	         $double=1;
	         $basket_position=$basket_position_counter;
	      }
	      $basket_position_counter++;
	   }
	}
	if ($double==1){
	   $ses_basket_amount[$basket_position]=$itemqty;
	   $newprice=$itemprice*$itemqty;
	   $ses_basket_price[$basket_position]=$newprice;
	}else{
	   $ses_basket_name[]=$basket;
	   $ses_basket_amount[]=$itemqty;
	   $ses_basket_price[]=$itemprice;
	   $ses_basket_id[]=$id;
	   $ses_basket_items++;
	}
}else{
	// Add new item to cart
	$ses_basket_items=1;
	$ses_basket_name[0]=$basket;
	$ses_basket_amount[0]=$itemqty;
	$ses_basket_price[0]=$itemprice;
	$ses_basket_id[0]=$id;
	session_register("ses_basket_items");
	session_register("ses_basket_name");
	session_register("ses_basket_amount");
	session_register("ses_basket_price");
	session_register("ses_basket_id");
}
// Delete Item when set to 0
if ($itemqty == "0") {
	array_splice ($ses_basket_name, $basket_position, 1);
	array_splice ($ses_basket_amount, $basket_position, 1);
	array_splice ($ses_basket_price, $basket_position, 1);
	array_splice ($ses_basket_id, $basket_position, 1);
	$ses_basket_items--;
}
}
// View Current Cart Status
if ($ses_basket_items>0){
  
  echo "<table cellpadding='0' cellspacing='0' border='0' width='230'><tr><td class='carthead'>ITEM</td><td align='center' class='carthead'>QTY</td><td class='carthead' align='right'>TOTALS </td></tr>";
   for ($basket_counter=0;$basket_counter<$ses_basket_items;$basket_counter++){
      $price=sprintf("%01.2f",$ses_basket_price[$basket_counter]);
      $quantity=$ses_basket_amount[$basket_counter];
      $name=$ses_basket_name[$basket_counter];
      echo "<tr><td width='130px' align='left' class='cart'>$name</td><td width='50px' align='center' class='cart'>$quantity</td><td width='50px' class='cart' align='right'>\$$price </td></tr>";
   }  
   $totalprice=sprintf("%01.2f",array_sum($ses_basket_price));
   $totalitems=array_sum($ses_basket_amount);
   echo "<tr><td align='left' class='cartbot'>CURRENT TOTALS:</td><td align='center' class='cartbot'>$totalitems</td><td align='right' class='cartbot'>\$$totalprice </td></tr></table>";
} else {
$ses_basket_items=0;
unset($ses_basket_name);
unset($ses_basket_amount);
unset($ses_basket_price);
unset($ses_basket_id);
echo "<div class='cartbot' align='center'>You have 0 item(s) $sub in your cart.</div>";
}
?>

 

to use it just include this where you want the code seen on your page, i also put that in a <div> tag for ease of use. Then set up a form sending the top 4 variables to it and your done.
