value minus value

Hi,
i have a question please

is that possible to make a field that
shows result of
(Value of field1) minus or plus (value of field2)
?

that will help to use flexicontent in many things other than articles

i am making a website for a shop
and trying to make some basic calculation functions between the fields

like + and -

i hope that will be possible
and thanks for your great support

Hello,
yes use raw field values inside your template (category_items.php or item.php file of you custom flexicontent template):

if your field is multiproperty e.g. weblink field
then please read this for more information

i tried to
put this code inside the template file
and this in the an text field default value
but i shows nothing : (
do i use it right ?
thanks

hello

1. do you still have error reporting on in Joomla Global configuration / Server TAB
please enable again

2. if you put inside the file this
echo "This point is reached";

do you see the above text ?

thanks for replying Mr ggppdk
i tried but there are no errors in the page
when i put the code in the template file it works well

but i want to show it inside a field
please help me as the whole website is now depending on that

HELP PLEASE : (

Hello

- the above code is very easy for me to add it to your custom template as column
... but to create a new field takes time, and don't want to hack existing fields

so let's do the first (the second (=create a new field will be done at an appropriate time and after some more thought/planning)

which template are you using ? a copy of the 'default' template?

you want this in category layout of the template or in item layout too ?

thanks for replying Mr ggppdk
i am really lucky because you are here with us

i am using a copy of the default template

and it would be very good if the field is shown in the category and item view
but if i have to choose i will need it to be in the category view in the first priority

thanks for helping us Mr ggppdk
