MySQL querying table - Doesn't show first result

Question

I have a DB (quartos) created with the following structure:

id_quarto  tipo_quarto  vista_quarto |
a      Single   Mar | 
b      Single   Mar |
c      Single   M         


        

Answer 1

You have extra $row = mysql_fetch_array($rs); just after mysql_query($strSQL);. Then in while loop you read $row again (second row in resultset). So your code will look

$strSQL = "SELECT id_quarto FROM quartos 
  WHERE tipo_quarto='". $_POST['tipo_quarto'] ."' 
  AND vista_quarto='". $_POST['vista_quarto'] ."'";
$rs = mysql_query($strSQL);
// $row = mysql_fetch_array($rs); Don't need this line!!!
while($row = mysql_fetch_array($rs)) 
{
   // output ....
}

Also, it always makes sense to add code for handling mysql errors.
