value minus value was created by days of summer

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):

Code:

$field_id1 = 55;
$field_id2 = 55;

$flds_arr = & $item->fieldvalues;

echo $flds_arr[$field_id2][0]  -  $flds_arr[$field_id1][0];

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

Thanks Mr ggppdk for your fast reply

can i use the

Code:

echo $flds_arr[$field_id2][0]  -  $flds_arr[$field_id1][0];

inside a field ?

as i wanted to show the result of the equation inside a field in the same item

as this example in the image
the earning = (selling) - (purshase)

can i use this method inside the earning field ?

thanks

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";
