How to refer filling of one form with the filling of other in Atk4 - atk4

Question

I have made two forms for logged users. The first one is for trip info (name, short description) and the second is for different landmarks (name, description) that are part of the trip of current user. Is it possible to "connect" the user with filling of trip form and the form for landmarks that is going to be used several times for different landmarks. I have the models "trips", "user" and "landmarks" with respective id's, but I can not solve the problem alone.
........................
I have tried this and it happened (thanks to Romaninsh):
function page_trips(){
$this->api->stickyGET('id');
$id=$this->api->auth->get('id');
$f=$this->add('Form');
$f->addField('line','name')->setNotNULL();
$f->addField('Text','short_desc')->setNotNULL();
$f->setSource('trips');
$f->setConditionFromGET();
$f->dq
->set('user_id',$id);
$f->addSubmit('Next');
if($f->isSubmitted())
{
$f->update();
$f->js()->univ()->location($this->api->getDestinationUrl('../targets')
)
->execute();
}
}
Now I can enter an info about new trip and save to table with respective user id. The rest of the task is to add different landmarks to current trip.

Not sure if it's what you are looking as i used a two page design and you would probably use another one to add/edit/delete landmarks but maybe this will give you some ideas.
I created a three tables in the database - trip, landmark and landmarktrip with the following definitions.
CREATE TABLE IF NOT EXISTS `landmark` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) CHARACTER SET latin1 NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=6 ;
INSERT INTO `landmark` (`id`, `name`) VALUES
(1, 'Xintiandi'),
(2, 'Pearl TV Tower'),
(3, 'YuYuan Gardens'),
(4, 'Shanghai Botanical Gardens'),
(5, 'Shanghai World Financial Centre');
CREATE TABLE IF NOT EXISTS `landmarktrip` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`trip_id` int(10) NOT NULL,
`landmark_id` int(10) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=7 ;
INSERT INTO `landmarktrip` (`id`, `trip_id`, `landmark_id`) VALUES
(1, 1, 1),
(2, 1, 2),
(3, 1, 3),
(4, 2, 3),
(5, 2, 4),
(6, 1, 5);
CREATE TABLE IF NOT EXISTS `trip` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(10) NOT NULL,
`name` varchar(255) COLLATE utf8_bin NOT NULL,
`short_desc` varchar(255) COLLATE utf8_bin NOT NULL,
`start_date` date NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='7741244' AUTO_INCREMENT=3 ;
INSERT INTO `trip` (`id`, `user_id`, `name`, `short_desc`, `start_date`) VALUES
(1, 1, 'Shanghai 1', 'First Trip To China', '2011-10-13'),
(2, 1, 'Shanghai 2', 'Return Visit', '2011-10-21');
And then created models in wwwroot/website/lib/Model as follows
Landmark.php
class Model_Landmark extends Model_Table {
public $entity_code='landmark';
public $table_alias='l';
function init(){
parent::init();
$this->addField('id')->mandatory(true)->system(true)->visible(false);
$this->addField('name')->mandatory(true);
}
}
Trip.php
class Model_Trip extends Model_Table {
public $entity_code='trip';
public $table_alias='t';
function init(){
parent::init();
$this->addField('id')->mandatory(true)->system(true)->visible(false);
$this->addField('user_id')->defaultValue($this->api->auth->get('id'))->visible(false);
$this->addField('name')->mandatory(true);
$this->addField('short_desc')->mandatory(true);
$this->addField('start_date')->dataType('date')->mandatory(true);
}
}
}
LandmarkTrip.php
class Model_LandmarkTrip extends Model_Table {
public $entity_code='landmarktrip';
public $table_alias='lt';
function init(){
parent::init();
$this->addField('id')->system(true)->visible(false);
$this->addField('trip_id')->refModel('Model_Trip')->mandatory(true);
$this->addField('landmark_id')->refModel('Model_Landmark')->mandatory(true);
}
}
Created two pages in wwwroot/website/page, one to add the trips and one for the itinerary as i dont see how with the form approach you are using, you can select which trip you want to see the details of.
trips.php
class page_trips extends page {
function init() {
parent::init();
$p=$this;
$c=$p->add('CRUD')->setModel('Trip');
$c->setMasterField('user_id', $this->api->auth->get('id'));
}
}
itinerary.php
class page_itinerary extends page {
function init() {
parent::init();
$p=$this;
$this->js()->_load('trip_univ');
$triplist=$this->api->db->dsql()->table('trip t')
->field('t.id')
->field('t.name')
->where('t.user_id', $p->api->auth->get('id'))
->order('t.start_date')
->do_getAssoc();
if ($_GET['trip']){
$curr_trip=$_GET['trip'];
} else {
$earliest=$this->api->db->dsql()->table('trip')
->field('min(start_date)')
->where('user_id',$this->api->auth->get('id'))
->do_getOne();
$curr_trip=$this->api->db->dsql()->table('trip')
->field('id')
->where('user_id',$this->api->auth->get('id'))
->where('start_date',$earliest)
->do_getOne();
}
$f=$p->add('Form')->setFormClass('horizontal');
$list=$f->addField('dropdown','trip')->setValueList($triplist)->set($curr_trip);
$list->js('change')->univ()->viewTrip($p->api->getDestinationURL(null), $list);
$lt=$p->add('CRUD')->setModel('LandmarkTrip');
$lt->setMasterField('trip_id', $curr_trip);
}
}
and one last file which allows the list to change the grid
Create a file called trips_univ.js in wwwroot/website/templates/js
trip_univ.js
$.each({
viewTrip: function(url, name){
document.location.href=url+'&trip='+$(name).val();
}
},$.univ._import);
So now, you can create trips using the CRUD to add, edit and delete rows.
Then go to the itinerary page to select a trip from the dropdown list or it defaults to the earliest trip and can add, remove or edit landmarks from the trip.

As you have solved your problem partially, I just need to add some notes on how to incorporate multiple actions into the form.
$form->setModel('Trip');
$form->addField('line','extrainfo'):
if($form->isSubmitted()){
$form->update();
$it=$this->add('Model_Itinerary');
$it->set('trip_id', $form->getModel()->get('id'));
$it->set('extrainfo', $form->get('extrainfo'));
$it->update();
}
This way you can create multiple models when the form is saved.
