html select State/Country dropdown in CakePHP ?
Hey, I was wondering if there Cake has a way to automatically generate a list of states/countries in the form of a dropdown menu. Maybe using the form helper or html helper ? Any help would be greatly appreciated. Thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups CakePHP group.

Setting Variables in Foreach Loops...
Hey all,
I'm trying to create a condition in my controller within a foreach
loop and then use this information in the view.
A quick note, $comments is a proper array, as is $online_now, so it is
not an array issue. The question is where (or if) I can set the
variable $user_online so that it it has a different value for each
case ? At the moment it is only returning the value of the last
element in the array (so, if there are 15 elements and the 15th
element is true, they are all true. If the 15th element is false,
they are all false. )
foreach ($comments as $comment) {
if (in_array($comment['Comment']['user_id'], $online_now))
{
$user_online = true;
}
else
{
$user_online = false;
}
}
$this-set('user_online', $user_online);
Any help would be greatly appreciated!

Re: Setting Variables in Foreach Loops...
Spark,
Thanks so much for the help. It solved the problem. And don't worry,
I wasn't actually using boolean variables as strings, just the actual
variables I am using are long, similar hyperlinks. Maybe red/blue
would have been a better choice :)

Brett, look:
BEGIN
LOOP1 - $user_online = true;
LOOP2 - $user_online = true;
LOOP3 - $user_online = false;
END
SET VARIABLE TO VIEW
$view-user_online = $user_online;
which value will be there in the view ?
Now, the simplest way, is to use the user array itself:
foreach ($comments as $comment) {
if (in_array($comment['Comment']['user_id'], $online_now))
{
$comment['Comment']['user_online'] = true;
} else {
$comment['Comment']['user_online'] = false;
}
}
when looping the $comments variable in view, just use that
['Comment']['user_online'] array key.
and , plase, don't use boolean variables as strings :)
true is not true

Re: Function to ignore an element of an array
Thanks man I appreciate the help. I probably will use a regular
expression on that 'split' step, something like $email_list = split(/,
\s*/, $data['Mail']['receiver_username']) to eliminate any spaces
following the commas.

One more thing, if you're not going to use a regular expression to
split a string, you should just use:
$input_usernames = explode(,, $data['Mail']['receiver_username']);
Cheers,

I would use a single query and some array functions. This is off the
cuff (untested) but should work as far as I can tell. Might do it
slightly differently if you need the id of the User as well to do
further processing, but you should be able to figure out the rest
yourself.
$input_usernames = split(,, $data['Mail']['receiver_username']);
$found_usernames = $this-User-findAll( array('User.username' =
$input_usernames), 'User.field' );
$found_usernames = Set::extract($found_usernames,
'{n}.User.username');
$orphan_usernames = array_diff($input_usernames, $found_usernames);
pr($orphan_usernames); // the list of usernames that were not found

Basically, I am writing a mailing class

foreach ($email_list as $receivers)

$conditions = 'User.id = '.$receivers_id.'';
$receivers = $this-User-field('username',
$conditions);
if ($receivers == 'FALSE')
{
//if one of the usernames is false, remove it and
continue with the
rest
}
}
If theres a comma (and hence more than one name listed) I split the
string and create an array.
I need a function in order to weed out usernames that are not in the
database. Any suggestions??

Pagination nightmares
I'm a beginner and struggling to use pagination correctly in cakephp.
The Bakery recommends using this code in the controller. I know its a
dumb question, but do I need to create a function called index() in
order to make this built in helper work ??
?php
class PostsController extends AppController
{
var $name = 'Posts'; // for PHP4 installs
var $components = array ('Pagination'); // Added
var $helpers = array('Pagination'); // Added
function index() {
$criteria=NULL;
list($order,$limit,$page) = $this-Pagination-
init($criteria); // Added
$data = $this-Post-findAll($criteria, NULL, $order, $limit,
$page); // Extra parameters added
$this-set('data',$data);
}
}
?

Newbie...really simple question
I'm trying to create a new Cakephp application, however when I load up localhost/cake it gives me the message Missing Database Table No Database table for model Post (expected posts), create it first. Posts is another application I previously made but deleted, and now I cannot get Cake to recognize my new application. I have changed the name of the database in the database.php configuration file so I'm not exactly sure what my problem is. Any suggestions would be greatly appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Cake PHP group.

Re: Newbie...really simple question
Well what I'm trying to do is forget about this table/database all
together...it was a simple example I was trying to do in order to
familiarize myself with cakephp, but I have since deleted all files
related to Post (the controller, model, views, sql table, etc.)
However when I try and load localhost cake, its telling me
Missing controller
You are seeing this error because controller PostsController could not
be found.
Notice: If you want to customize this error message, create app\views/
errors/missing_controller.thtml.
Fatal: Create the class below in file : app\controllers
\posts_controller.php
?php
class PostsController extends AppController {
var $name = 'Posts';
}
I just want to forget about this stupid Posts_controller and
everything associated and create another application in cake without
this message interfering! Quite frustrating...any advice?

It's complaining that there is no 'posts' table in your database. I
know it's a dumb question, but are you sure the table is in the
database you've specified in database.php?
