[SOLVED] this " if .. else" statement doesn't work, please help !

[vanvoquan]

Hi everyone, I try to use this form for my site but the if and else statement doesn't work. I want my customers to chose for the quantity they desire and if they don't, the form automatic post an value of " 1 " to the quantity in the database. But for some reason, if my customers not chose the quantity, the form automatic post a " 0 " for the quantity in the database. Below is the code of the form, any help will be greatly appriciate. thank you.

			<tr>
  <?
   
	if($row['selling_method']=="auction" or $row['selling_method']=="dutch_auction")
{ 
if($row[Quantity] > 0)
{
?>
<form name="fix_form" action="detail.php" method="post">
<td height="27" class="banner1">Quantity</td><td>:</td>
    <td align="left">
<select name=qty <?if($row[Quantity]==0 or $row[status]=='Closed'){echo "disabled";}?>>
 <option value="Quantity">Quantity</option>
<? for($i=1;$i<=$row[Quantity];$i++)
{
?>
 <option value="<?= $i;?>"><?= $i;?></option>
<? 
}
?>
</select>
</td>
<? 
}
?>
    </tr>
     <?
     }
 else
 { 
 ?>
	 <input type="hidden" name="qty" value="1">
 <?
 }
 ?>

<tr>
	<input type="hidden" value="1" name="flag">
	<input type="hidden" value="<?= $err_flag; ?>" name="err_flag">
	<input type="hidden" value="fix" name="sell_method">

              <td class="banner1">Buy It Now Price</td>
              <td class="banner1">:</td>
              <td width="45%" class="detail888txt">US <?= $row['currency']; ?><?= $row['quick_buy_price']; ?>
&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp<input type="image" src="images/images/buyit.gif" name="Image70" value="buy" width="81" height="24" border="0" id="Image70" onmouseout="MM_swapImgRestore()" onmouseover="MM_swapImage('Image70','','images/images/buyito.gif',1)" onClick="return confirm_buynow(<?=$row[Quantity];?>)"; <?if(($row[Quantity]==0) or ($row[status]=='Closed') or ($today_date<0)){echo "disabled";}?>

You can't use php like that .. it can't modify the form after printing it out.

 

But what you can do is have the php script that accepts the form check the quantity, and set it to 1 if it's not set in the form.

 

Edit: Alternatively, you can use javascript to set the value just before the form is submitted.

thanks for your respond. I'm not very good at php. Can you provide me in more detail about how to write a php script that accetps the form check the quantity. Thanks alot !

[btherl]

Well, if you have a form, you must also have a script that accepts values from the form.  If you post the code for that I can show you how to modify it to have a default value for quantity.

Thanks for all the helps. With the guides from all of you, I fix the code and it works. Thanks so much.

if($qty==0)
{
$query="update placing_item_bid set status='Closed',Quantity='0',quantity_sold='1',sale_price=$fix where item_id='$item_id'";
mysql_query($query);
}
else if($qty >  0)
{
$query="update placing_item_bid set status='Closed',Quantity='$quantitans',quantity_sold='$qty',sale_price=$fix where item_id='$item_id'";
mysql_query($query);
}
