Setting Up Accounts
667
Look back at the script in Listing 29.2.This time around because of the value of
$action, you get different behavior.You get a slightly different header, as follows:
do_html_header($_SESSION['auth_user'], "Warm Mail - ".
format_action($action),
$_SESSION['selected_account']);
More importantly, you get a different body, as follows:
case 'store-settings':
case 'account-setup':
case 'delete-account':
display_account_setup($_SESSION['auth_user']);
break;
This is the typical pattern: Each command calls a function. In this case, you call the
display_account_setup() function.The code for this function is shown in Listing
29.3.
Listing 29.3 display_account_setup() Function from output_fns.php—
Function to Get and Display Account Details
function display_account_setup($auth_user) {
//display empty 'new account' form
display_account_form($auth_user);
$list = get_accounts($auth_user);
$accounts = sizeof($list);
// display each stored account
foreach($list as $key => $account) {
// display form for each accounts details.
// note that we are going to send the password for all accounts in the HTML
// this is not really a very good idea
display_account_form($auth_user, $account['accountid'], $account['server'],
$account['remoteuser'], $account['remotepassword'],
$account['type'], $account['port']);
}
}
When you call the display_account_setup() function, it displays a blank form to add
a new account, followed by editable forms containing each of the user’s current email
accounts.The display_account_form() function displays the form shown in Figure
29.4.You use it in two different ways here:You use it with no parameters to display an
empty form, and you use it with a full set of parameters to display an existing record.
This function is in the output_fns.php library; it simply outputs HTML, so we do not
go through it here.
