I didn't find anything suitable in the docs and tutorials: I use minishop2 and in my cart I display price and count like this:
[[+price]] [[+count]]
but also I need to add total sum for the rows, which is price * count. How can I do this on modx without writing some special code?
Something like [[+price]*[+count]]
- could I do something like this in the template?
You could try to work something out with Output Modifiers: http://rtfm.modx.com/revolution/2.x/making-sites-with-modx/customizing-content/input-and-output-filters-(output-modifiers)
Example:
[[+price:mpy=`[[+count]]`]]
