Cannot add button in updateOperation

[cod3rshotout]

Hello, I need some help.

I'm trying to add a "preview" button in the updateOperation, so I have the following content:

public function setupUpdateOperation()
{
    $this->crud->setUpdateContentClass('col-md-12');
    $this->setupCreateOperation('update');
    $this->crud->addButtonFromView('line', 'preview', 'preview', 'beginning');
}

but the button doesn't appear at all, I have also created the blade file within this directory: vendor/backpack/crud/buttons/preview.blade.php, which have this content:

<a href="/intranet/{{ $entry->slug }}?preview=1">
    <i class='fa fa-list'></i>Preview
</a>

Essentially, I need to add a button near "Annulla":

@pxpm @tabacitu any help?

Modify a copy of form_save_buttons.blade.php from the vendor directory into /resources/views/vendor/backpack/crud/inc. Then include your custom button, as for example :

@include('custom.buttons.mybutton')

[tabacitu]

That should work great if you want to add the button for all CRUDs, yes. I'd only add one thing - that in order to still benefit from the changes Backpack might make inside form_save_buttons.blade.php, it's a good idea for you custom view to:

• include the view in Backpack's vendor dirctory
• then include your custom view

That way, you just add something, not really override anything.

Hey @cod3rshotout - I realise it's unintuitive, but the addButtonFromView() method will only have effects on the List operation, not the Update operation. @rchampagneca 's solution above should work great!

Hi @tabacitu, it'd be great if we could add buttons to create/show/update views using addButton method.

[tabacitu]

I would freakin' love that too!

Maybe in our next version. Right now, the buttons that do exist in Create/Update are called SaveAction and behave differently. But even then... we would have to choose between:

• A) buttons alongside SaveActions;
• B) refactoring SaveActions so they are buttons;

I would not agree to B, not worth the breaking change. I would maaaybe agree to A... If the use cases were solid. And we'd find a way to document it so it's not confusing.

Which brings me to my question:

What button did you need to add to the Create/Update page @dsarmento ? What did you want it to do?

Cheers!

Hi @tabacitu, thanks for your answer.

I wanted to extended the PageManager add-on and add a preview page button/functionality. This would require me to add some sort of JS to get all the fields and POST them to a custom operation route.

I believe the SaveActions wouldn't allow me to do this because it saves the record first?

Do you have suggestions?

Thanks again.

[tabacitu]

Oh ok. Indeed with SaveActions you can only change what happens AFTER saving. so it's not a good fit.

But you can achieve that with a script widget: https://backpackforlaravel.com/docs/6.x/base-widgets

Inside the script widget, you can add a little bit of JavaScript that adds a button wherever you want, and opens a page in a different tab for preview.
