I am using ui-component form edit and would like to add custom button "customButton" with all post data. However, it doesn't post any data except form key.
My code
$data = [
'label' => __('Print Address'),
'class' => 'save',
'data_attribute' => [
'url' => $this->urlBuilder->getUrl('*/*/printAddress', ['id' => $this->getRequest->getParam('id')]);
],
'sort_order' => 80,
];
Check CMS module as an example. You need to pass following params for submit form.
vendor/magento/module-cms/Block/Adminhtml/Page/Edit/SaveButton.php
'data_attribute' => [
'mage-init' => [
'buttonAdapter' => [
'actions' => [
[
'targetName' => 'cms_page_form.cms_page_form',
'actionName' => 'save',
'params' => [
false
]
]
]
]
]
],
