    <p>I'll make it simple, let's say i have a shopping cart, and three different prices:</p> <ol> <li>$price</li> <li>$specialprice</li> <li>$salesprice</li> </ol> <p>of course there are product quantities.</p> <p>The first step of math is:</p> <pre><code>&lt;?php $price_regular = $price * $quantity $price_special = $specialprice * $quantity $price_sales = $salesprice * $quantity ?&gt; </code></pre> <p><strong>So let me make a simple example, after adding 3 products in cart:</strong></p> <ol> <li>Product A - 30$ ($price)</li> <li>Product B - 25$ ($specialprice) (old price was 30$)</li> <li>Product C - 22$ ($salesprice) (old product was 35$)</li> </ol> <p>The summ shoud be 77$. </p> <p><strong>This is the result i want to get from my code.</strong></p> <p><strong>But HOW?</strong></p> <p>I tried doing smthing like:</p> <pre><code>&lt;?php $totalprice = $totalprice + $price_regular; ?&gt; </code></pre> <p>but it only gives me the summ of REGULAR price. I need the code to calculate exactlly as in my simple example with product A - B - C</p> <p>This is the real code from my file:</p> <pre><code>$totalprice = 0; $totalarticles = count($itemsonpage); for ($i=0;$i&lt;=(count($itemsonpage) - 1);$i++){ $productslist[$i]['id'] = $itemsonpage[$i]['productid']; $products-&gt;ShowByID($itemsonpage[$i]['productid']); $productslist[$i]['code'] = $products-&gt;code; $products-&gt;ShowLangDataByID($products-&gt;id,$chooselang); $productslist[$i]['name'] = $products-&gt;name; $productslist[$i]['quantity'] = $itemsonpage[$i]['quantity']; $productslist[$i]['price'] = $itemsonpage[$i]['price']; $productslist[$i]['specialprice'] = $products-&gt;specialprice; $productslist[$i]['salesprice'] = $products-&gt;salesprice; $productslist[$i]['allprice'] = $products-&gt;price * $productslist[$i]['quantity']; $productslist[$i]['allprice2'] = $products-&gt;specialprice * $productslist[$i]['quantity']; $productslist[$i]['allprice3'] = $products-&gt;salesprice * $productslist[$i]['quantity']; $totalprice = $totalprice + $productslist[$i]['allprice']; </code></pre>

    1. COthere are large chunks of logic missing here, how to know which of the 3 price options to apply for a start. the pseudo code example is meaningless, how about some real code.

    2. COI am also not following - you can't add 3 numbers or something else is missing?

    3. COWhy is it that the first product should apply with its regular price, and the second product with the special price, and the third product with the sales price? If you can explain this, you have your logic to decide which price to add. Additional questions: What if there are only two products in the basket, or four or more?
