Displaying - instead of 0 ???

[cp914]

Quick background... I bought an auction program with plenty of bugs. Todays bug that I can't figure out is that it is displaying a - (dash) when I would prefer it to display 0 (zero) in instances of "total fees due" or in the "fee chart" if it's a flat fee of 0.  0% works fine.

 

The code related to it is spread out on a handful of files but I think it's mostly related to the following.

 

   	
if (is_array($setup_fee))
   	{
   		foreach ($setup_fee as $key => $value)
   		{
   			if ($value['amount'])
   			{
   				if ($value['calc_type'] == 'flat')
   				{
   					$output['amount'] += $value['amount'];
   					$fee_display = $this->display_amount($value['amount'], $this->setts['currency']);
   				}
   				else if ($value['calc_type'] == 'percent')
   				{
   					$output['amount'] += $this->round_number($item_details['start_price'] * $value['amount'] / 100);
   					$fee_display = $value['amount'] . '%';
   				}

   				if ($item_relist)
   				{
   					$output['amount'] = $this->round_number($output['amount'] - $output['amount'] * $this->fee['relist_fee_reduction'] / 100);
   				}

   				$output['display'] .= '<tr class="c1"> '.
   					'	<td width="150" align="right"><b>' . GMSG_SETUP_FEE . ':</b></td> '.
   					'	<td align="left" nowrap colspan="2"><b>' . $fee_display . $value['display'] . '</b></td> '.
   					'</tr> ';

   				## now add the row on the invoices table
   				if ($user_payment_mode == 2 && $add_invoices)
   				{
   					$account_balance += $output['amount'];

   					$tax_settings = $this->tax_amount($output['amount'], $this->setts['currency'], $user_details['user_id'], $this->setts['enable_tax']);			

   					$sql_insert_invoice = $this->query("INSERT INTO " . DB_PREFIX . "invoices
						(user_id, item_id, name, amount, invoice_date, current_balance, can_rollback, tax_amount, tax_rate, tax_calculated, reverse_id) VALUES
						('" . $user_details['user_id'] . "', '" . $item_details['auction_id'] . "', '" . GMSG_SETUP_FEE . "',

   					$sql_update_user_balance = $this->query("UPDATE " . DB_PREFIX . "users SET
						balance='" . $account_balance . "' WHERE user_id='" . $user_details['user_id'] . "'");
   				}
   			}
   		}
   	}

   	foreach ($fees_no_tier as $key => $value)
   	{
   		if ($value[1])
   		{
   			$fee_details = $this->display_fee($key, $user_details, $item_details['category_id'], $item_details['list_in'], $voucher_details, $apply_tax);

  				if ($item_relist)
  				{
  					$fee_details['amount'] = $this->round_number($fee_details['amount'] - $fee_details['amount'] * $this->fee['relist_fee_reduction'] / 100);
  				}

   			$output['amount'] += $fee_details['amount'];

   			if ($fee_details['amount']) ## only do this if there is a fee
   			{
   				$output['display'] .= '<tr class="c1"> '.
   					'	<td width="150" align="right"><b>' . $value[0] . ':</b></td> '.
   					'	<td nowrap colspan="2"><b>' . $fee_details['display'] . '</b></td> '.
   					'</tr> ';


   				## now add the row on the invoices table
   				if ($user_payment_mode == 2 && $add_invoices)
   				{
   					$account_balance += $fee_details['amount'];

   					$tax_settings = $this->tax_amount($fee_details['amount'], $this->setts['currency'], $user_details['user_id'], $this->setts['enable_tax']);			
   					
   					$sql_insert_invoice = $this->query("INSERT INTO " . DB_PREFIX . "invoices

    		}
   	}

	$output['display'] .= '<tr class="c5"><td colspan="3"></td></tr><tr class="c2"> '.

		'</tr> '.
    		'<tr class="c5"> '.
        	'	<td><img src="themes/' . $this->setts['default_theme'] . '/img/pixel.gif" width="150" height="1"></td> '.
		'	<td colspan="2"><img src="themes/' . $this->setts['default_theme'] . '/img/pixel.gif" width="1" height="1"></td> '.
  			'</tr> ';

   	return $output;
}

 

I'll really really appreciate the help.

Let me ask this in a different way.

 

What would make a db value of "0.00" display as "-" ?

 

And/or how would one make "0.00" a value that is treated the same as "0.01", "1.00" , ect.

[litebearer]

roughly, at any point in the script where it is displaying a value, add an 'if' clause ie psuedo code

if value>0 echo value else echo "0.00"

 

in much of your code the script is concatenating values to text so you need to look thru carefully to find those places ie

 

$display = "some html here" . "some content here " . some value here TA DA . " more content" . "more html"

 

understand?
