echo"<select>";
 while ($row = mysql_fetch_array($rezultat1))
{  if ($row['biljka_id']==$GET['b']) {
echo "<option value=".$row['biljka_id']." selected='selected' >".$row['naziv']."</option>";
} else { echo "<option value=".$row['biljka_id'].">".$row['naziv']."</option>";
}
echo"</select>";

Answer 1

Following is the short code.

You need not use if else statement as you need to justify only one variable depending upon condition.

You can do it with ternary operator.

<?php
echo "<select>";
while ($row = mysql_fetch_array($rezultat1)) {
    $selected = ($row['biljka_id']==$GET['b']) ? 'selected="selected"' : '';
    echo "<option value=".$row['biljka_id']. $selected ">".$row['naziv']."</option>";
}
echo"</select>";
?>
