A coder, wise in the way of JS could probably do most of what you need without any knowledge of Gravity Forms. </p> https://legacy.forums.gravityhelp.com/topic/price-calculation-based-on-birthdate#post-90301 Mon, 12 Nov 2012 15:55:01 +0000 breakerke 90301@https://legacy.forums.gravityhelp.com/ <p>been browsing the support docs about including javascript somehow...</p> <p>Could I perhaps use the "Gform post render" to have a hidden (or read-only) field populated based on a query I make?</p> <p>I should be able to use javascript to retrieve the year out of the date dropdown I use, compare it to the current date and fill the destination field with the right price?</p> <p>Coding that is another thing however :) </p> https://legacy.forums.gravityhelp.com/topic/price-calculation-based-on-birthdate#post-90298 Mon, 12 Nov 2012 15:51:26 +0000 David Peralty 90298@https://legacy.forums.gravityhelp.com/ <p>Yeah, age category. One choice or the other. You couldn't have the price updated through conditional logic on a date field, best solution I could come up with. </p> https://legacy.forums.gravityhelp.com/topic/price-calculation-based-on-birthdate#post-90295 Mon, 12 Nov 2012 15:37:28 +0000 breakerke 90295@https://legacy.forums.gravityhelp.com/ <p>what would I put on the radiobuttons? Have them choose in which "age category" they reside? Or how exactly do you mean? </p> https://legacy.forums.gravityhelp.com/topic/price-calculation-based-on-birthdate#post-90267 Mon, 12 Nov 2012 14:29:05 +0000 David Peralty 90267@https://legacy.forums.gravityhelp.com/ <p>You could have a radio button that has the two options and then conditional logic for each of those choices. That would then give you the result you want. </p> https://legacy.forums.gravityhelp.com/topic/price-calculation-based-on-birthdate#post-90266 Mon, 12 Nov 2012 14:23:52 +0000 breakerke 90266@https://legacy.forums.gravityhelp.com/ <p>hmm... too bad :( that would make the signup form awesome... We have to let our registrants know somehow how much they have to pay. </p> https://legacy.forums.gravityhelp.com/topic/price-calculation-based-on-birthdate#post-90181 Mon, 12 Nov 2012 10:41:13 +0000 David Peralty 90181@https://legacy.forums.gravityhelp.com/ <p>We don't have an easy way of doing this currently as you can't use conditional logic against date picker fields. It would require custom JavaScript and/or PHP code to make happen automatically. I just don't know of any built-in way to do this. </p> https://legacy.forums.gravityhelp.com/topic/price-calculation-based-on-birthdate#post-90088 Mon, 12 Nov 2012 05:48:16 +0000 breakerke 90088@https://legacy.forums.gravityhelp.com/ <p>Hey,</p> <p>I'm totally loving Gravity Forms and using it on 1 of my websites for all different sort of forms.</p> <p>One of those forms is a membership signup. I could create all fields with no problem but can't figure out how I can determine the price they have to pay.</p> <p>Basically, the price is determined on when they were born :<br /> ex.<br /> 20 € if born in 2003 and later<br /> 60 € if born between 2002 &amp; 1993<br /> ...</p> <p>can this somehow be calculated? Off course there is a datepicker field for the birthdate.</p> <p>Thanks in advance! </p>
