README

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
 }
 }
}
