This extensions makes it possible to modify the TCA of container children elements.

Examples:

• The content element "text" shouldn't have a field "header_link" if inside a container
• The header of content element "header" must be required if in colPos "100" of a container.

Usage:

Install with composer req georgringer/container-modify-fields.

Configuration

The configuration must be done in PageTsConfig with the following syntax:

    TCEFORM.tt_content.container {
        <container-ctype>.<colpos>.<child-ctype>.<field> {
            # currently supported is only:
            required = 1
            disabled = 1
            fixedItemValue = 1
        }

        # Instead of <colpos> and <child-ctype> also "_all" is valid
    }

Example 1

The behaviour of elements inside container "b13-2cols-with-header-container" is changed:

• All elements: No header_link field
• Element "text": No header field

TCEFORM.tt_content.container {
  b13-2cols-with-header-container {
    _all {
      _all {
        header_link.disabled = 1
      }
      text {
        header.disabled = 1
      }
    }
  }
}

Example 2

The behaviour of elements inside container "b13-2cols-with-header-container" is changed:

• The header element inside colPos "200" is set to required

TCEFORM.tt_content.container {
  b13-2cols-with-header-container {
   200 {
      header {
        header.required = 1
      }
    }
  }
}

Example 3: fixedItemValue

This setting works only with select items: all other items are removed, so its value can't be changed any more.

The behaviour of all elements inside accordion container is changed:

• the header_layout is set to Hidden [100]. In accordion, field "header" is used for accordion header and shouldn't be displayed in content block
• the space_before_class is set to small (=> example for string values)

TCEFORM.tt_content.container {
  accordion.101._all {
    header_layout {
      fixedItemValue = 100
    }
    space_before_class {
      fixedItemValue = small
    }
  }
}
