and this what i have done in controller as you want it to be..
class WartaRutin extends Controller
{
public $implement = ['Backend\Behaviors\ListController','Backend\Behaviors\FormController','Backend\Behaviors\ReorderController' ];
public $listConfig = 'config_list.yaml';
public $formConfig = 'config_form.yaml';
public $reorderConfig = 'config_reorder.yaml';
public function __construct()
{
parent::__construct();
BackendMenu::setContext('Mismaiti.MyWarta', 'main-menu-item', 'side-menu-rutin');
}
public function formExtendFieldsBefore($form) {
// we are checking we are creating record or updating
// or even we can use $form->context here but I used $model->id
// if $form->context == 'update'
// if $form->context == 'create'
if(is_null($form->model->id)) {
// create time
$iteration = $form->fields['kebum']['maxItems'];
if(is_numeric($iteration) && $iteration > 0) {
$emptyFields = [];
while($iteration > 0) {
$emptyFields[] = ['jeniskeb' => ''];
$iteration--;
}
$form->model->kebum = $emptyFields;
}
}
}
}
and it return an error when i tried to execute-- i have replace all repeater_data to kebum
"Undefined index: kebum" on line 30 of C:\xampp\htdocs\mywarta\plugins\mismaiti\mywarta\controllers\WartaRutin.php
am i missing something here..?
hmm, we can use one trick, that as you may only need this at create time or may be you can extend it at update time as well,
I used field repeater_data you can replace it with your field field
fields.yaml
fields:
... other fields ...
repeater_data:
label: Repeater
oc.commentPosition: ''
prompt: 'Add new item'
maxItems: '5'
span: auto
type: repeater
form:
fields:
title:
label: Text
oc.commentPosition: ''
span: auto
type: text
category:
label: Dropdown
oc.commentPosition: ''
options:
1: 'Item 1'
2: 'Item 2'
span: auto
type: dropdown
controller
inside your controller you need to add this method and code
public function formExtendFieldsBefore($form) {
// we are checking we are creating record or updating
// or even we can use $form->context here but I used $model->id
// if $form->context == 'update'
// if $form->context == 'create'
if(is_null($form->model->id)) {
// create time **logic**
$iteration = $form->fields['repeater_data']['maxItems'];
if(is_numeric($iteration) && $iteration > 0) {
$emptyFields = [];
while($iteration > 0) {
// here you need to provide at least one field
// which you used in repeater I used `title`
// and let it be empty or may be some default value
$emptyFields[] = ['title' => ''];
$iteration--;
}
// dummy fields assignment to current form model
$form->model->repeater_data = $emptyFields;
}
// **logic**
}
else {
// if you need to adjust data in update time
// you need to find difference and then need to add
// additional dummy data as we are adding above
}
}
There is 2 scenarios create time and update time
Create time
When user is creating record we will add dummy fields so repeater will show them as they are already there and it is done using maxItems property of that field so its fully dynamic, now user don't need to press that button.
Update time ( Suppose maxItems=5)
Now for 2nd scenario we have else condition if you wish you can add some logic and do your stuff there, Suppose user may add only 2 records at a time so next time we need to add 3 dummy fields (2 filled + 3 dummy = total 5 as maxItem) so you can calculate there and add it from else part.
I hope this will help you, If you find any difficulties please comment.
