Is it possible to have a pay other amount, just like there is for CiviDonate, for an event fee?

Thanks!

For that use case, you can actually mark certain price fields as "admin only" in the price set configuration.  Then those options will not show on the regular user "front end" registration page -- they'll only be available to the admin "back end" registration page.  It would eliminate the potential for abuse, but also means that speakers/sponsors could not self-register.

As tmccartney said

...do this by having one or more zero-dollar items in the price set for conference presenters, sponsors, etc.

If you aren't using a price set (although I suggest you do) you can still enter zero dollar options when you set up the regular fees.

If the amount owing is zero, the person registering does not need to fill in their CC details to complete their registration although those fields still show.



If you don't want to go the blunt route of having a price set that says:

Fees:
narcolepsy patients       $0
others                            $50


then you can camouflage it a bit by only offering the $50 option in the first price field in the price set. Then add another price field with hidden negative amounts.  This approach also lets you offer discounts on the fee for, say, partners of narcolepsy patients if you should want to.   An example of the second price field you could add with amounts that would be hidden shown in brackets is:

I am attending this event as:

A narcolepsy patient    (-$50)
The partner of a narcolepsy patient (-$25)
An medical practitioner treating narcolepsy patients)  ($0)
A supporter of narcolepsy research ($0)

This latter approach also lets you collect info on those attending (although you can always do that with a profile - which is actually easier to search).

Yes, you can do this with a price set.  Create a price set with one "text / numeric quantity" field, and set the price of that field to $1.  Leave "required" unchecked.

In the "Fees" section for the event setup, choose the price set you just created instead of filling out the "regular fees" section.

Now you'll have an event with a price field where registrants can enter an arbitrary dollar amount, or leave it blank and register for free.

Is there a way to calculate a total, regardless? In other words, total will be calculated. Then, we create a field such as you are suggesting above. They can pay what they want towards the total, and return later to pay more. Is this possible and if so, how?
