Dynamic Registration Value

Hi,

I have a donation box that a user fills in upon registration in case they want to donate. Currently, I have to set a static amount they would be charged. However, I want this value to be changed based on what the user enters in this field (E.G. if they enter 10, I want this to be added to the current registration value).

How may I implement this using s2member?

Thanks.

I’m not 100% sure what you’re trying to do here. Are you using this field in the registration form, so they would add the amount prior to clicking the register button?

Hi,

Yes. I’m using this field in the PayPal Pro registration form. In other words, I have added a field called “Donation” to s2member’s list of fields, and it is getting displayed in the form.

I could have used a PHP execution plugin to set the ra attribute of the form to the new price if I were using two steps (first for donation, and second for registration) but i want all of this to be in one single step.

Thanks.

My first thought was to hook into the payment processing but I don’t see any hooks in the file. I’ll have to check some more.

If there is a hook that gives you access to all the data from the form, you could set the “ra” value = to the custom field… but I’ve not found a good hook for it yet.

Hi Terry,

I don’t believe this is possible. The s2Member Pro-Forms load through the shortcode. You can change the values of the shortcode attributes before the shortcode gets parsed (i.e., the Pro-Form is displayed), but you can’t change those values after the shortcode has been parsed.

So, there are two ways to create a Pay What You Want type system: If you’re using the PayPal buttons, you can do something like this.

If you’re using Pro-Forms, you’ll need to use a two-step process, with the first step asking for the donation amount and the second step displaying the Pro-Form with the previously entered price dynamically configured into the Pro-Form shortcode.
