Two things with this, and opinions may vary...
Functions shouldn't print or echo anything, rather you should return what is to
be displayed. Also you may want to clean up/condense your while in the
following manner;
<?PHP
function init_auth_list(){
$return="<select name=author> <option value=\"\">select the name of the
author</option\>";
$query="select name from author order by name";
$result=pg_exec($GLOBALS["db"],$query);
$numrows=pg_numrows($result);
# $i=0; moved to while statement
while($i=0;$i<$numrows;$i++;){
$row=pg_fetch_row($result,$i);
$return.="option name=\"".$row[0]."\">$row[0]</option>";
# $i++; moved to while statement
}
$return.="</select>";
return $return;
}
?>
then print your select box with the following
<?PHP echo init_auth_list(); ?>
much of that is personal preference mind you;
