Deprecation: #92435 - StandaloneView for EmailFinisher 

See forge#92435

Description 

The EmailFinisher class of EXT:form was extended for the possibility to use FluidEmail in TYPO3 v10. Therefore the previously used StandaloneView has now been marked as deprecated along with the configuration option templatePathAndFilename.

Impact 

Using the StandaloneView will trigger a PHP E_USER_DEPRECATED error. Using templatePathAndFilename for custom templates will also trigger a PHP E_USER_DEPRECATED error.

Affected Installations 

All installations not already using FluidEmail for the EXT:form EmailFinisher.

Migration 

Adjust your finisher configuration to use FluidEmail by setting useFluidEmail: true.

Before:

finishers:
   -
     identifier: EmailToReceiver
     options:
       useFluidEmail: false
Copied!

After:

finishers:
  -
    identifier: EmailToReceiver
    options:
      useFluidEmail: true
Copied!

For custom templates, replace templatePathAndFilename with templateName and templateRootPaths.

Before:

finishersDefinition:
  EmailToReceiver:
    options:
      templatePathAndFilename: EXT:sitepackage/Resources/Private/Templates/Email/ContactForm.html
Copied!

After:

finishersDefinition:
  EmailToReceiver:
    options:
      templateName: ContactForm
      templateRootPaths:
        100: 'EXT:sitepackage/Resources/Private/Templates/Email/'
Copied!
