Usage

1. You only need to adjust the column configuration of your backend_layout

Restrict certain content element fields

• To allow a limited set of values for content element fields use allowed.field = [list of comma separated values]

Examples:

columns {
 1 {
 name = Column with header and textmedia elements
 colPos = 3
 colspan = 6
 allowed {
 CType = header, textmedia
 }
 }
}

columns {
 1 {
 name = Column with News plugin only
 colPos = 3
 colspan = 6
 allowed {
 CType = list
 list_type = news_pi1
 }
 }
}

Combine multiple content element fields

• The example allows multiple content element types (text and list) while restricting plugin types to news only.

Example:

columns {
 1 {
 name = A column with restricted list_type and "normal" CType
 colPos = 3
 colspan = 6
 allowed {
 CType = textmedia, list
 list_type = news_pi1
 }
 }
}

Deny certain content element types

• To remove a set of values from content element fields use disallowed.field = [list of comma separated values]

Examples:

columns {
 1 {
 name = Column without divider, plain html and table elements
 colPos = 3
 colspan = 6
 disallowed {
 CType = div, html, table
 }
 }
}

columns {
 1 {
 name = Column with header and list, without News plugin
 colPos = 3
 colspan = 6
 allowed {
 CType = header, list
 }
 disallowed {
 list_type = news_pi1
 }
 }
}

Limit the number of content elements

• To restrict the number of content elements use maxitems = [number of elements]

Example:

columns {
 1 {
 name = Column with one textmedia 
 colPos = 3
 colspan = 6
 allowed {
 CType = textmedia
 }
 maxitems = 1
 }
}

Content Defender needs the runtime cache to be available. Please ensure that this cache doesn't use a \TYPO3\CMS\Core\Cache\Backend\NullBackend backend.
