Hello,
could you please guide me with the following question/code:
The job is to build a special booking form. Version: Joomla 1.5.//RSForm Pro 44.
I read
demo.rsjoomla.com/calculation-form-example and searched the forum, but cannot figure it out myself. I think I do not see/understand how to mix various fields and PHP together since I am not so well versed in coding. So I would much appreciate if you could help me out with the code. IF I once have the correct syntax I guess I am experienced enough to apply it in analogy.
General fields like Name, Address etc. are no problem. I could also address the fields with a simple calculation. The difficult part is to set-up the following calculation. I put the field names in [ ]. By name I mean the “Name” I can enter in the wizard. I am not sure if this is the ID.
The form has one default value [default] that increases with each submitted form based on total amount chosen. I build a hidden field for that. But at the same time I need to show the field since it is the default value for this particular user. --> Problem Nr. 1 I tried to build another field, to show the result but do not succeed in displaying the number.
The increment [increment] is fixed - another hidden field in the form I built.
Now the user can choose between options [options] - I set-up a radio button field with x items defining the choice. No problem here.
The calculation to be performed is to take the default value [default] * the amount (1,2,3 ..) of the field [options] + the [increment] when the [option] is >1. Here is an illustration:
current default value + 1* option = current default value
current default value + 2* option = current default value*2 + increment
current default value + 3* option = current default value*3 + increment*2
(...) basically a divergent series or a Gauss series If I recall school correctly.
-->Problem Nr. 2 - This I could not get to work at all I guess mostly since there is a mix of radio and text fields unlike the example where it is either/or.
Then I want to show the end amount – so I set-up another field for that. Since I do want to show the final amount prior to the submission I think I need to include the calculation in the [option] selection like onChose instead of onSubmitt. I could not get it to work.
--> Problem Nr. 3
Finally a user submits the form. As a result the next form should do exactly the same calculation but start with [default] from the last form. So I need to set a database query, but how?
--> Problem Nr. 4 --- I could not find an explanation in the forum (I checked:
www.rsjoomla.com/forum/37-rsform-pro/219...bmissions.html#23804 and
www.rsjoomla.com/forum/37-rsform-pro/222...se-fields.html#24231)
A practical example (not exactly the same) to explain the goal of the form better are booked seats starting from 0 and going up with each submission based on seats booked in each form (the increment factor is missing here).
Since it is a kind of urgent project I have no problem to pay/donate an extra support fee if needed. Just tell me how.
In case you are a 3rd party knowing how to implement this, just PM me.
Thank you very much for any help!
