I have a Model wih the following fields:

Id(primary key), geo_poi_id(foreign key), searchterm

I want to pass a value to the

 /backend/exitcontrol/countrymanager/poisearchwordcontroller/create/

that says that geo_poi_id has to be selected on value 2(or whatever the current poi is we are editing, this number can be anything that'll be passed on by url) when creating a new entry.

And I have no idea how to format the url or access those values from within the controller or to pass it on to the display methods so the correct default values will be displayed.

Please help, the documentation is drawing a blank for any search term I can come up with... this should be really straight forward

Edit 1

I figured out that I can read the value of the url via $this->params

So in the controller I can read the value 2 with the url

/backend/exitcontrol/countrymanager/poisearchwordcontroller/create/2

by using the $this->params[0] which will give me the passed value 2 in the controller.

Now, how do I pass this on to my create view so it will default select value 2?

My controller:

<?php namespace ExitControl\CountryManager\Controllers;

use Flash;
use BackendMenu;
use Backend\Classes\Controller;
use ExitControl\CountryManager\Models\POIModel;
/**
 * Sliders Back-end Controller
 */
class POISearchWordController extends Controller
{
    public $implement = [
        'Backend.Behaviors.FormController',
        'Backend.Behaviors.ListController'
    ];
    public $formConfig = 'config_form.yaml';
    public $listConfig = 'config_list.yaml';

    public function __construct()
    {
        parent::__construct();

        BackendMenu::setContext('ExitControl.CountryManager', 'countrymanager', 'poi');
    }

    public function index_onDelete()
    {
        if (($checkedIds = post('checked')) && is_array($checkedIds) && count($checkedIds)) {

            foreach ($checkedIds as $itemId) {
                if (!$slider = POIMOdel::find($itemId))
                    continue;

                $slider->delete();
            }

            Flash::success('Successfully deleted those selected.');
        }

        return $this->listRefresh();
    }
}

my fields.yaml

# ===================================

    searchterm:
        span: left
        label: exitcontrol.countrymanager::lang.poimodel.searchterm

did you find a solution because I am in the same situation as you

Good news everyone, yes I did :-) By extending the fields via the controller.

public function formExtendFields($form)
    {
        $para = null;
        if(isset($this->params[0]) && substr($this->params[0],0,2) === 'sw' ) {
            $para = $this->params[0];
        }
        else if(Session::get('poimodel')) {
            $para = Session::get('poimodel');
        }

        //throw new ValidationException(['poimodel'=>Cookie::get('poisearchwordpoiid','NOT SET')]);
        if($para !== null ) {   
            Session::put('poimodel',$para);
            $this->vars['para'] = $para;
            //$number = $this->asExtension('FormController')->formGetContext();
            $form->addFields([
                    'poimodel' => [
                            'span'=> 'left', 
                            'nameFrom'=>'poiname',
                                'type'=>'relation',
                                'label'=>'Point of Interest',
                                'default'=>substr($para,2)
                    ],
            ]);
        }
    }

Yeah ! I will test but how you call this function ?

Thank you! I spend a lot of hours looking for something like this.

Tschallacka - I'm a bit confused as to where you changed the parameter to include 'sw' at the beginning - all of the forms I create just have the ID parameter. If instead you usually set the Session variable, other than in this function, where did you do that at?

How do you get url var value in create.htm?
