Configure variants¶

Setup¶

plugin.tx_wtcart_pi1 {
  ...
  db.variants {
    # db table which stores the available colors
    db.table = tx_myext_domain_color
    # db field which stores the color name
    db.title = title
    # db field which stores the price
    db.price = price
    # db field which stores the tax class
    db.taxclass = tax_class
  }
  ...
}

Let's focus on the t-shirt example again and introduce the 2nd variant dimension. It's quite easy and straight forward.

Setup¶

plugin.tx_wtcart_pi1 {
  ...
  db.variants {
    # db table which stores the available colors
    db.table = tx_myext_domain_color
    # db field which stores the color name
    db.title = title
    # db field which stores the price
    db.price = price
    # db field which stores the tax class
    db.taxclass = tax_class
    db.variants {
      # db table which stores the available sizes
      db.table = tx_myext_domain_size
      db.title = title
      db.price = price
      db.taxclass = tax_class
    }
  }
  ...
}

Example¶

• table "tx_myext_domain_product", product A, price = 10
• table "tx_myext_domain_color", color green, price = 20
• table "tx_myext_domain_size", size M, price = 30

The example above depicts that the price for the product A is 10. If you create a variant based on the color green the price in the cart will be 20. If you create a variant based on the color green and the size M the price in the cart will be 30.

This behaviour can be changed by either using a price inheritance or one of the price calculation methods. Right now the settings price_calc_method and inherit_price should not be combined for a variant since this has not been tested intensively enough.

Price inheritance¶

If the price inheritance is activated for a variant the default price calculation (see above) is not applied, i.e. the price of the respective variant is not taken into consideration. Instead the price of the parent variant dimension/ product is utilized.

In order to use this feature you have to set the correct database field via TypoScript. The following example does it for the 2nd variant dimension (in our case "size").

plugin.tx_wtcart_pi1.db.variants.db.variants.inherit_price = inherit_price

If the variant "t-shirt, color green, size M" with the activated flag "inherit_price" is added to the cart the final price will be 20 (instead of 30).

Price calculation methods¶

As described above you can define the method for calculating the price of a variant. The database field which stores the method is defined via the following TypoScript setup.

plugin.tx_wtcart_pi1.db.variants.db.price_calc_method = ...

During the price calculation of a variant wt_cart does the following:

• get the price calculation method for this variant
• get the "price" of the variant

After that wt_cart calculates the final price of the variant.

Right now there are 5 methods available.

Constants¶

Enter the correct POST parameter name for the unique variant field (dimension 4) inside your order form.

plugin.wtcart.gpvar.variants.4 = variants|4

Setup¶

plugin.tx_wtcart_pi1 {
  ...
  settings {
    variants {
      4 < .3
      4.data = GP:{$plugin.wtcart.gpvar.variants.4}
    }
  }
  ...
}
