将 tt_content 的 TCA 更改为子类型？

Question

Is it possible, for a specific plugin (eg newspage_pi1 ), to configure its TCA, ie its back-end form display? Just for that specific plugin, because when changing tt_content 's TCA for the list type (ie plugins) like this:

$GLOBALS['TCA']['tt_content']['types']["list"] = [
    'showitem' => "
  (tabs..palettes..columns..etc...)"];

It changes it for all plugins, and I only want to change it for the newspage_pi1 list_type .

Yes, I know that I can use 'subtype_value_field' => 'list_type' and then subtypes_excludelist and subtypes_addlist to add or remove fields for specific plugins. But this is not nearly as powerful as setting showitem directly, since it allows to define new tabs, palettes, position the fields how you want to, etc.

I also know about FlexForms , but these only control the Plugin Options field, not all the other ones.

Is there a way to change the showitem for a specific plugin?

Thanks a lot in advance!

Frankly said, what you actually want is not a subtype but another type, since it needs to change fields other than the usual plugin / pi_flexform configurations.

So instead of adding that subtype as a plugin you should add it as another CType to get the full power of showitem .

Basically, this is how we add any kind of plugin too, since it makes more sense to have real database fields at hand instead of faking them with XML data structures.

As mentioned in the description here https://api.typo3.org/master/class_t_y_p_o3_1_1_c_m_s_1_1_core_1_1_utility_1_1_extension_management_utility.html#ab4f6c66990aca246eac5390a76f0c83c

... - or more generally use this function to add an entry to any selectorbox/radio-button set in the FormEngine
