How to put a PHP function in a Button "on click" attribute?

Question

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.

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...

routes.xml:

<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" />
    </route>
</router>

------------------------------EDIT---------------------------------

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

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;
    parent::__construct();
}
/**

View  page action

@return void

*/
public function execute()
{
    $txt = 'HUDSON SAVEHEADER : ';
    $this->logger->log('DEBUG', $txt);
}

}

Yes, actually i want to use this "Save Header" button to save just one field of the form. I will update the post with the entire form. — Rafael Fagundes, Jun 16 '20 at 18:27

Actually i created the button, but i want to put an php function on the "on click" attribute — Rafael Fagundes, Jun 16 '20 at 19:23
a php function will not work as per your requirement, although you can use js for the same. on hitting the button the data can be saved through ajax and on ajax response you can populate your form — Afreen Sheikh, Jun 16 '20 at 20:28
hey guys, now i got the problem that i don't know exactly how to call the controller url. — Rafael Fagundes, Jun 18 '20 at 18:54

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

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

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:

require([
        'jquery',
        'jquery/ui',
        'Magento_Ui/js/modal/modal'
    ], function($){
            function saveHeader() {
                 $form = $('#formId');
                 $.ajax({
                        type: 'POST',
                        url: 'url',
                        data: {
                            xxx,
                            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? — Rafael Fagundes, Jun 17 '20 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. — xanka, Jun 18 '20 at 04:45
So i'm trying this but happens this exception: Invalid template file: 'Hub_Api::view/deleteheader.phtml' in module: '' block's name: 'deleteheader' — Rafael Fagundes, Jun 23 '20 at 14:42

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? – Rafael Fagundes Jun 17 '20 at 18:01
you can also write location.reload – ParulThakkar Jun 18 '20 at 05:41
So the url would be like $url = 'Hub_Api/Controller/SaveHeader/id/' . $this->getDataId(); ? i think i'm passing the url wrong. – Rafael Fagundes Jun 18 '20 at 12:47

try this

public function getButtonData()
{
    $message ='Are you sure you want to do this?';
    $url = $this->getUrl("api/data/deleteheader"); 
    return
        [
            'label' => __('Save Header'),
            'class' => 'myclass',
            'on_click' => 'confirmSetLocation('{$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. – Rafael Fagundes Jun 18 '20 at 12:29
give screenshot of your router.xml file for admin and controller action code syntax – ParulThakkar Jun 18 '20 at 12:48
hey, i put the code for routes.xml and the directories. The "SaveHeader" controller is in "Controller\Adminhtml\Data" directory – Rafael Fagundes Jun 18 '20 at 14:06
Please put like this adminroutename/data/saveheader – Msquare Jun 19 '20 at 04:12
please check my updated answer and update me – Msquare Jun 19 '20 at 04:15
hey, i already tried this and still don't working... Could the error be on the Controller class? – Rafael Fagundes Jun 19 '20 at 11:20
So, i think the problem is on the "SaveHeader" button, because i can call the "SaveHeader" Controller using the construct of another controller. – Rafael Fagundes Jun 19 '20 at 12:50
I made it, but i used this : $url = $this->getUrl("api/data/deleteheader"); – Rafael Fagundes Jun 23 '20 at 17:15
