powermail | Massive mail hosting infrastructure

I am using powermail where I have added a file upload which I want to restrict with PNG,JPG and PDF file formats. Since I unfortunately do not work as long as TYPO3 and the extension Powermail I do not know exactly where I have to make the changes. I have already seen in another forum post that you can make the adjustments in the setup.

Are there any docs that can help me to overwrite the Flexform of powermail extension into my site package? So that I can edit the field configuration.

Please help, I have been searching for this very long.

Thank you.

I have a powermail form in which I use a select box with multi selection. In the email body the selected values are written as a comma separated list but with a space after each comma.

The developer of powermail (powermail 7.4.2 / TYPO3 9.5) has given me an answer on github: https://github.com/einpraegsam/powermail/issues/680

He directed me to an hardcoded entry in the answer.php of powermail.

I've changes the line in the answer.php to my needs but the spaces in the e-mail remain.

Can anyone give me a tip how to remove these spaces in the mail body for the multi select value list?

I need to add a custom validator to the datepicker field. By default, this field comes without any validators.

I've already made the validator settings visible in the TCA of tx_powermail_domain_model_field and added my custom validator as usual.

Now I need the attributes data-parsley-customXXX and data-parsley-error-message added to the HTML input field which is usually done via the the viewhelper in ValidationDataAttributeViewHelper.php:
https://github.com/einpraegsam/powermail/blob/develop/Classes/ViewHelpers/Validation/ValidationDataAttributeViewHelper.php#L342
https://github.com/einpraegsam/powermail/blob/develop/Classes/ViewHelpers/Validation/ValidationDataAttributeViewHelper.php#L348

This is the code I need to extend: https://github.com/einpraegsam/powermail/blob/develop/Classes/ViewHelpers/Validation/DatepickerDataAttributeViewHelper.php#L32

i want to write powermail data in the data table of an own extbase extension. the form delivers a uid of a sys_category which i want to persist in my extension.

The relevant lines in my finisher:

I would like to transmit yes or no as value for checkboxes in Powermail (marketing.sendpost.values). If the checkbox is not selected, nothing is transmitted by default. Is it possible to set a default value per checkbox? I have created the checkbox with Text|yes in TYPO3.

My TypoScript

I've a Fluid template with a partial. To fetch a localized string I'm using .

I wonder how to use f:translate as an argument for my partial.

According to the documentation there is a inline-notation: {f:translate(key: 'someKey', extensionName)} but this doesn't seem to work in my case and causes an error:

I wonder what is the easiest way to translate a powermail form into multiple languages (approx. 10 languages, for this example let's just use English (default) and translate into German).

What have i done so far:

• installed powermail through composer
• created a form with 5 fields.
• added that form to a page.
• saving form to database.

What i need is a way to translate this form into German, but i have no idea where to start. Can anyone point me in the right direction?

I'm using the TYPO3 version 10 and have a problem with the plugin grids for bootstrap. The grids works with images and texts with no errors but doesn't display the powermail form.

Here's a pic of the problem

I've included before the "Main" static template.

Has anyone an idea what causes the error and how to resolve it?

Thanks in advance
