Even after years working with #TYPO3
I am still impressed by the amazing and powerful configuration possibilities with #TypoScript
. Just discovered a very elegant way how to configure the behaviour of the quick search fields in the backend when you want to link another content element.
On one page I want to change the behaviour of this quick search for a specific field in a content element and limit the results that can be searched.
To be concrete in calendar (extension: cal
) event content elements (table: tx_cal_event
) I want to limit the results that are available as locations for this event (field: location_id
) which are queried from the table tt_address. I only want to get results that have set the field tx_cal_controller_islocation
in the table tt_address
. Of course you could edit the $TCA (T
rray) of tx_cal_event and change the definition of the suggest wizard globally, but there is a much more flexible and elegant way.
Just put this TSconfig in a PageTS or UserTS depending how you want this behaviour to be deployed, for example for a group of users only or a specific page only.
# Limit Location Suggest Wizard to cal-islocation addresses
TCEFORM.tx_cal_event.location_id.suggest.tt_address.searchCondition = tx_cal_controller_islocation=1
This renders an input field next to the selector of group-type fields (when internal_type is db) or of select-type fields (using foreign_table). After the user has typed at least 2 (minimumCharacters) characters in this field, a search will start and show a list of records matching the search word. The "suggest" wizard's properties can be configured directly in TCA or in page TSconfig (see TCEFORM properties).
Each level of the configuration overwrites the values of the level below it:
"suggest.default" is overwritten by "suggest.[queryTable]".
Both are overwritten by "[table name].[field].suggest.default" which itself is overwritten by "[table name].[field].suggest.[queryTable]"
Configuration for all suggest wizards in all tables
Configuration for all suggest wizards from all tables listing records from table
Configuration for the suggest wizard for field [field]in table [table name]
[queryTable]Configuration for the suggest wizard for field [field]in table [table name] listing records from [queryTable]
