716 Chapter 30 Building a Mailing List Manager
This function runs three database queries to collect the name and blurb for a list from
the lists table, the number of subscribers from the sub_lists table, and the number of
newsletters sent from the mail table.
Viewing List Archives
In addition to viewing the list blurb, users can look at all the mail that has been sent to a
mailing list by clicking on the Show Archive button.This activates the show-archive
action, which triggers the following code:
case 'show-archive':
display_items('Archive For '.get_list_name($_GET['id']),
get_archive($_GET['id']), 'view-html',
'view-text', '');
break;
Again, this function uses the display_items() function to list the various items of mail
that have been sent to the list.These items are retrieved using the get_archive() function
from mlm_fns.php.This function is shown in Listing 30.11.
Listing 30.11 get_archive()Function from mlm_fns.php—This Function Builds an
Array of Archived Newsletters for a Given List
function get_archive($listid) {
//returns an array of the archived mail for this list
//array has rows like (mailid, subject)
$list = array();
$listname = get_list_name($listid);
$query = "select mailid, subject, listid from mail
where listid = '".$listid."' and status = 'SENT'
order by sent";
if($conn=db_connect()) {
$result = $conn->query($query);
if(!$result) {
echo "Unable to get list from database.";
return false;
}
$num = $result->num_rows;
for($i = 0; $ifetch_array();
