Hi i'm new at magento2 and i want to put a PHP function in an "on click" attribute of a button on ui component form.

Specifically on this "Save Header" button. button

So, actually i want to use this "Save Header" button to just save two fields of the form, the fields (Nome Header, Valor Header).


The "on click" attribute. In this "on click" i want to call a php function...

on click


<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
<router id="admin">
    <route id="api" frontName="api">
        <module name="Hub_Api" />



So now my "SaveHeader" button is like that, but still don't working, maybe the url is passed wrong: new saveheader button

SaveHeader.php (Controller):

namespace Hub\Api\Controller\Adminhtml\Data;

class SaveHeader extends \Magento\Framework\App\Action\Action { protected $logger;

public function __construct(
    \Psr\Log\LoggerInterface $logger
) {
    $this->logger = $logger;

 * View  page action
 * @return void
public function execute()
    $txt = 'HUDSON SAVEHEADER : ';
    $this->logger->log('DEBUG', $txt);

try this

public function getButtonData()
    $message ='Are you sure you want to do this?';
    $url = $this->getUrl("api/data/deleteheader"); 
            'label' => __('Save Header'),
            'class' => 'myclass',
            'on_click' => 'confirmSetLocation('{$message}', '{$url}')',
            'sort_order' => 100

You can write you php code into this controller action file.

I Hope This Helps You.

  • Would be something like this? $url = 'Hub_Api/Controller/SaveHeader/id/' . $this->getDataId(); I don't know, i think i'm passing the url wrong. Jun 18, 2020 at 12:29
  • give screenshot of your router.xml file for admin and controller action code syntax Jun 18, 2020 at 12:48
  • hey, i put the code for routes.xml and the directories. The "SaveHeader" controller is in "Controller\Adminhtml\Data" directory Jun 18, 2020 at 14:06

hello you can change your code with following code

$fieldset->addField('registered', 'button', array(
            'label' => Mage::helper('core')->__('Send e-mail to all registered customers'),
            'value' => Mage::helper('core')->__('Button Caption'),
            'name'  => 'registered',
            'class' => 'form-button',
            'onclick' => "setLocation('your url')",
  • In 'your url' you mean the Controller url? Jun 17, 2020 at 18:01
  • you can also write location.reload Jun 18, 2020 at 5:41
  • So the url would be like $url = 'Hub_Api/Controller/SaveHeader/id/' . $this->getDataId(); ? i think i'm passing the url wrong. Jun 18, 2020 at 12:47

This is my idea hope it help. In getButtonData() function add on_click to javascript function something like 'saveHeader()'

add your template in layout call to UI form: sample we have MODULE-NAME_CONTROLLER-NAME-ACTION.xml this content like

   <referenceContainer name="content">
       <uiComponent name="your_ui_form"/>
       <block class="Magento\Framework\View\Element\Template" name="XXX"  template="NAMESPACE_MODULENAME::html/js.phtml"/>

In js.phtml file create new saveHeader() function call ajax to submit form element to your custom module controller (php).

This sample for js.phtml file content:

    ], function($){
            function saveHeader() {
                 $form = $('#formId');
                        type: 'POST',
                        url: 'url',
                        data: {
                            form_key: 'qiIiwjIPOdmrA0Uq',
                            return_session_messages_only: 1
                        dataType: 'json',
                        showLoader: true,
                        context: $form

Good Luck!

  • For what i should replace the "xxx" ? and how i could call the controler by the button? Jun 17, 2020 at 17:09
  • "xxx" are field you need send to save like nome_api: $('input[name="nome_api"]').val() when you click button it will call javascript function is saveHeader() then it will submit data to url. Url is mean your php controller file in this file you can get data and save it. All step above is mean get you "header" data and submit it to another php controller then save.
