For example, here is the edit product for our admin - you can see that it has extended the standard product information quite a bit. (yes we do have a "monthly profit report" that uses the cost basis field, and yes, when you do a "special" it advises the margin and profit decrease and carries that to the report. And no, that one isn't getting released as an add-on.)

Hi met00,
I have just added the Margin Report contribution to my store, looking good so far. I see you have made some addition on your categories.php that makes it show right there the margin in amount and %, could I please borrow that code from you...??

Ummm, Margin Report is NOT from me so I have no idea what fields they call from the database (we modified the code to meet our needs as margin report didn't).

Below is the code where we add costs and compute margin...

<? // MOD: added MSRP ?>
         <tr bgcolor="#ebebff">
            <td class="main"><?php echo TEXT_PRODUCTS_PRICE_MSRP; ?></td>
            <td class="main"><?php echo tep_draw_separator('pixel_trans.gif', '24', '15') . '&nbsp;' . tep_draw_input_field('products_msrp', $pInfo->products_msrp); ?></td>
          </tr>
          <tr bgcolor="#ebebff">
            <td class="main"><?php echo TEXT_PRODUCTS_PRICE_NET; ?></td>
            <td class="main"><?php echo tep_draw_separator('pixel_trans.gif', '24', '15') . '&nbsp;' . tep_draw_input_field('products_price', $pInfo->products_price, 'onKeyUp="updateGross()"'); ?></td>
          </tr>
          <tr bgcolor="#ebebff">
            <td class="main"><?php echo TEXT_PRODUCTS_PRICE_GROSS; ?></td>
            <td class="main"><?php echo tep_draw_separator('pixel_trans.gif', '24', '15') . '&nbsp;' . tep_draw_input_field('products_price_gross', $pInfo->products_price, 'OnKeyUp="updateNet()"'); ?></td>
          </tr>
<?
$margin = $pInfo->products_price - $pInfo->products_cost;
if ($pInfo->products_price != 0) $marginp = (1 - ( $pInfo->products_cost / $pInfo->products_price )) * 100;
if ($margin < .01 ) $margin = "<font color=red>".$margin."</font>";
?>
         <tr bgcolor="#ebebff">
            <td class="main"><?php echo TEXT_PRODUCTS_PRICE_COST; ?></td>
            <td class="main"><?php echo tep_draw_separator('pixel_trans.gif', '24', '15') . '&nbsp;' . tep_draw_input_field('products_cost', $pInfo->products_cost); ?> <i>Margin: <?echo $margin; ?> (<?echo sprintf('%01.2f',$marginp); ?>%)</i></td>
          </tr>

Hope that helps.

It will, I will be able to work it out from that, thanks!

[MindTwist]

That did the trick, I hardly had to change anything since my variables are the same.

I thought that the shown margin would update real time like the prices do (you change the net price, and the gross price will change to show your price + taxes), guess I hoped for too much I will try to make it work that way
and let you know.

Thx!

So here is my solution, now the info gets updated real-time as you change any of the values, gross value, net value, or product cost:



Here I created updateMargin, and added a call to the function on updateGross and updateNet, so if the net or gross values change, the margins will do so too.

 function updateGross() {
  var taxRate = getTaxRate();
  var grossValue = document.forms["new_product"].products_price.value;

  if (taxRate > 0) {
    grossValue = grossValue * ((taxRate / 100) + 1);
  }

  document.forms["new_product"].products_price_gross.value = doRound(grossValue, 4);
  updateMargin();
}

function updateNet() {
  var taxRate = getTaxRate();
  var netValue = document.forms["new_product"].products_price_gross.value;

  if (taxRate > 0) {
    netValue = netValue / ((taxRate / 100) + 1);
  }

  document.forms["new_product"].products_price.value = doRound(netValue, 4);
  updateMargin();
}

function updateMargin() {
  var netValue = document.forms["new_product"].products_price.value;
  var costValue = document.forms["new_product"].products_cost.value;

  document.getElementById('margin').innerHTML=doRound(netValue - costValue,2);
  document.getElementById('margin_pct').innerHTML=doRound( (costValue*100)/netValue , 2);
} 
  

And here is the HTML part used before the PRICE_NET and PRICE_GROSS parts:

  <tr bgcolor="#ebebff">
    <td class="main"><?php echo TEXT_PRODUCTS_PRICE_COST; ?></td>
    <td class="main"><?php echo tep_draw_separator('pixel_trans.gif', '24', '15') . '&nbsp;' . tep_draw_input_field('products_cost', $pInfo->products_cost, 'onKeyUp="updateMargin()"'); ?> <i>Margen: <label id="margin"></label> (<label id="margin_pct"></label>%)</i></td>
  </tr> 

Also, a little bit down there is this piece of code:

 <script language="javascript"><!--
updateGross();
updateMargin();
//--></script> 
  

I added the updateMargin() there, so the margins will be shown on page load.
