Namespace\Modulename\Controller\Adminhtml\Index\Save.php

public function execute() {
 $dynamicRowData = $this->getRequest()->getParams();
}

Response of $dynamicRowData:

Array
(
 [fee_id] => 4
 [fee_name] => test
 [display_type] => checkbox
 [fee_options] => Array
 (
 [0] => Array
 (
 [store_1] => test 1
 [store_2] => test 1
 [fee_type] => F
 [record_id] => 0
 [fee_price] => 10
 [store_0] => test 1
 [position] => 1
 [initialize] => true
 [is_default] => 1
 )
 [1] => Array
 (
 [record_id] => 1
 [store_1] => test 2
 [store_2] => test 2
 [fee_price] => 20
 [fee_type] => F
 [store_0] => test 2
 [position] => 2
 [initialize] => true
 [is_default] => 0
 )
 )
 [default] => Array
 (
 [0] => option_0
 )
 [fee_price] => Array
 (
 [value] => Array
 (
 [option_0] => Array
 (
 [0] => 10
 )
 [option_1] => Array
 (
 [0] => 20
 )
 )
 )
 [option_0] => test 1
 [option_1] => test 2
 [position] => Array
 (
 [order] => Array
 (
 [option_0] => 1
 [option_1] => 2
 )
 )
 [form_key] => 4Nj0oUjsJRfKgtWo

I'm saving is_default value like follows:

if (isset($data['is_default'])) {
 foreach ($dynamicRowData as $recId => $record) {
 if ($recId == $data['is_default']) {
 $dynamicRowData[$recId]['is_default'] = 1;
 }
 else {
 $dynamicRowData[$recId]['is_default'] = 0;
 }
 }
}

On edit page if I print Dataprovider's data, I'm getting following array for fee_options:

[fee_options] => Array
(
 [0] => Array
 (
 [store_1] => test 1
 [store_2] => test 1
 [fee_type] => F
 [record_id] => 0
 [fee_price] => 10
 [store_0] => test 1
 [position] => 1
 [initialize] => true
 [is_default] => 1
 )
 [1] => Array
 (
 [record_id] => 1
 [store_1] => test 2
 [store_2] => test 2
 [fee_price] => 20
 [fee_type] => F
 [store_0] => test 2
 [position] => 2
 [initialize] => true
 [is_default] => 0
 )
)

I can't save "is_default" field value, how can I make it selected at the time of Edit form. Can anyone please let me know if I'm missing anything? Thanks in anticipation.

• Ronak Rathod: please attach the data of $this->getRequest()->getParams()
• Dhara Bhatti: @RkRathod Response of $this->getRequest()->getParams() added in question.
• Ronak Rathod: check my answer
• Ronak Rathod: check condition under the foreach loop

Answer 1

Try This :-

 $dynamicRowData = $this->getRequest()->getParam('fee_options');
 foreach($dynamicRowData as $data)
 {
 if($data['is_default'] == 0)
 {
 //save is_default value
 }
 }

• Dhara Bhatti: Not working. I have added more details. Please check.
• Ronak Rathod: any error ??????
• Dhara Bhatti: Not getting any error, my form gets saved without selected default value.
