How to hook and change label on page save button?

[JayGee]

I'm trying to do something I thought would be simple, but maybe not!...

I'm trying to hook ProcessPageEdit to change the label/text displayed on the page save button in certain circumstances based on fields in that page. But can't figure if it's possible to target the button.

I can get to the button actions in the drop down with ProcessPageEdit::getSubmitActions but this array doesn't contain the top level label only the drop down values.

Can anyone point me in the right direction here please?

TIA ?

When you search for getSubmitActions you will find some thread talking about adding and removing buttons.
At some places you can see how titles/labels of those buttons were set.

As a starting point:

Maybe that helps?

Thank @wbmnfktr. I did see that thread from Ryan, but it didn't seem to cover modifying the default button, more about adding a new one.

However on second thoughts I'm going to use the drop down actions anyway as may need more than one option, but it would be good to know about editing the default label if anyone has any insight on this for future reference.

Check and try the following, I think the link provided all the infos.

/// get and mod inputfield submit
$wire->addHookBefore('InputfieldSubmit::render', function($event) {
  /// get page being edited from from query string
  $id = (int) $this->input->get->id; // ⚠️ sanitize it, do not trust your xss ninja admins 
  $page = $this->pages->get($id); 

  /// i.e. exit if page name is not 'hello'
  if($page->name !== 'hello') return;

  /// get the object the event occurred on
  $submit = $event->object;

  /// make sure to target the `submit save` button (it could be more than one button)
  $name = $submit->attr('name');
  if($name !== 'submit_save') return;

  /// change the button's label (attribute: value)
  $submit->attr("value", "Foobar");
}); 

/// mod the inputfield submit dropdown
$wire->addHookAfter('ProcessPageEdit::getSubmitActions', function($event) {
  $actions = $event->return; // array actions
 
  /// get page being edited from event's object
  $page = $event->object->getPage(); 

  /// i.e. exit if page name is not 'hello'
  if($page->name !== 'hello') return; 

  $actions['to_the_moon'] = [
    'value' => 'to_the_moon', 
    'icon' => 'moon-o', 
    'label' => '%s + Go Moon ?', // Save + Go Moon
    'class' => '', 
  ];

  $event->return = $actions;
}); 

/// process the new action dropdown
$wire->addHookAfter('ProcessPageEdit::processSubmitAction', function($event) {
  $action = $event->arguments(0); // action name, i.e. 'cache'
  if($action === 'to_the_moon') { 
      $event->message("Your page was rocketed to the moon ??", "nogroup");
  } 
});

/// remove all the dropdown action but keep our new one
$wire->addHookAfter('ProcessPageEdit::getSubmitActions', function($event) {
  $actions = $event->return; // array of actions, indexed by name 
  /* bd($actions) ?
  'exit' => array
  'view' => array
  'add' => array
  'next' => array
  */
  /// remove all action, let just keep our `to the moon` action
  foreach($actions as $action) {
    $name = $action['value'];
    if($name === 'to_the_moon') continue;
    unset($actions[$name]); 
  }
  $event->return = $actions;
}); 


/// bonus - add a second button on the current edit page
$this->addHook('ProcessPageEdit::buildForm', function($event) {
  /// get page being edited from from query string
  $id = (int) $this->input->get->id; // ⚠️ sanitize it, do not trust your xss ninja admins 
  $page = $this->pages->get($id); 

  /// i.e. exit if page name is not 'hello'
  if($page->name !== 'hello') return;

  /// quite self explanatory
  $href = $this->config->urls->admin."page/edit/?id=$id&to=the_moon";
  $field = $this->modules->get('InputfieldButton');
  $field->attr('id+name', 'input_moon');
  $field->attr('class', $field->class);
  $field->attr('value', 'To the moon ?');
  $field->attr('href', $href);

  $event->return = $event->return->append($field);
});

Thanks @flydev ?? this is awesome. I've not even had a chance to try it out yet but I can see I had previously been doing something wrong...

/// change the button's label (attribute: value)
  $submit->attr("value", "Foobar");

Had been trying to target 'label' rather than button value... duh! Probably led me down a blind alley from the get go!

To try it, you can just create a dummy page with page's name `hello` and paste the whole code in `ready.php` ?
