Remove $ from Total Field

What does the full URL look like once the merge tag is added to your query string?

It does not look like the code is being processed at all. Can you make sure that you changed the form ID from 148 to your proper form ID?

Also, are you using a "redirect" for your confirmation setting, and the query string is already populated and working there?

This code is pretty simple and works, but it does not look like it's working for you at all. Can you post the actual code you are using, the whole thing, including the hook? And, post a link to your form if you can.

You can duplicate this code three times, changing the form ID in each one. But in addition, you will need to rename the function, otherwise you will get an error "Fatal error: Cannot redeclare function" because you are trying to declare the function custom_confirmation more than once.

You can name them like this:
custom_confirmation_1
custom_confirmation_2
custom_confirmation_3

Or with the form ID:
custom_confirmation_148
custom_confirmation_17
custom_confirmation_2

Or go totally different like this:
confirmation_for_product_one
confirmation_changer
confirmation_strip_dollar

When you change the function name, you need to do it on the line which begins "add_filter" and also on the line which begins "function". So, copy the block of code so it appears three times, leave one alone, then edit the other two to apply to different forms, then change the function name twice in each block. If you have trouble, paste your code at pastie.org or pastebin.com and let us know what error you are getting.

Please share a link to the page on your site where we can see a form which uses this functionality. I can't see why it would work in the preview mode and not on the live site. The code looks OK.

What do you mean send the total and other information hidden? Do you mean you do not want it sent as a GET request and visible as part of the URL?

It looks like Moneris is using the query string with the information visible. How will you send them the information if not in the query string like this?

If you want to hide that information, you will have to use something other than a GET request, like your initial example here. If you want to do that, please open a new topic. We will need a different approach, possibly using the gform_after_submission hook. http://www.gravityhelp.com/documentation/page/Gform_after_submission It is more complicated than sending the variables in the query string like you have done so far.
