TYPO3 Extension content_defender

Define allowed or denied content element types in your backend layouts

Installation

Simply install the extension with Composer or the Extension Manager.

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

• In order to restrict content elements using multple field conditions, please note that it might be necessary to allow empty values as well. A basic example would be to allow multiple content element types (text and list) while restricting plugin types to news only. If the editor wants to add a new text element, the plugin type stays empty.

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
    }
}
