I should be using if($_POST['max_id'] ='') { and notif($_POST['max_id']
!=='') { correct? Since it is a comparative function just the = should
be correct.
Can someone take a look at this solution and tell me if this would be a descent solution for his problem?
I use this logic all over my code base, let me know if it is efficient, clean, well structured, etc...
if ( isset($_POST['max_id']) ) {
$max_id = (int)$_POST['max_id'];
if ( empty($max_id) ) {
die('not a valid id');
# or some other, more graceful, way of catching the error
}
$SQL = "SELECT * FROM payment_request WHERE id = '{$max_id}'";
if ( ( $result_info = mssql_query($SQL) ) === false ) {
die(mssql_error());
# again, maybe something more graceful here
}
if ( mssql_num_rows( $result_info ) == 0 ) {
die('nothing to display');
# again, maybe something more graceful here
} else {
while ( $row_info = mssql_fetch_array($result_info) ) {
echo '<input type="Text" value="'.$row_info['my_value'].
'" size="20" maxlength="16" name="my_value">';} } } -- Enjoy, Jim Lucas Different eyes see different things. Different hearts beat on different strings. But there are times for you and me when all such things agree. - Rush
