Configure multiple data sources¶

It is possible to add products to your cart from multiple data sources (i.e. database tables). Imagine the following scenario. Your products are based on tt_news, cal and your own extension called myfancyproducts. In the past you had to create 3 wt_cart plugins to handle this use case. Now you only need on wt_cart plugin.

Example constants¶

Below you can find an example for your TypoScript constants.

plugin.tx_wtcart_pi1 {
  gpvar.tableId = tx_myext_tableid
  db {
    table1 = tt_news
    table2 = tx_cal_event
    table3 = tx_myfancyproducts_domain_model_event
  }
}

Property

gpvar.tableId*

Data type

Text

Description

Enter the correct POST parameter name which stores the product table id (integer) of your order form. wt_cart uses this number for internal purposes. It can't be a string. The tableId will never be displayed.

Property

db.table1 … db.tableN*

Data type

Text

Description

You can set up n tables which store your products (e.g. tt_news). db.table is still working and not affected by db.table1

Furthermore you have to extend your order forms (on each list or detail page). According to our example above you have to add 3 order forms to your tt_news single view, your cal single view and your myfancyproducts single view. The order view must include a hidden field with the name tx_myext_tableid. Within this field you add the static value 1 (for tt_news), 2 (for cal) or 3 (for myfancyproducts).
