Imagine that you have a Workshop Post type that includes upcoming events. In these events, they have a standard form format in order for participants to register. 

Depending on specific events, the form will be sent to different target email addresses.

Instead of creating manually multiple forms for posts, you just need to create only a standard form. This article will show you to manage it. 


Step 1: Set up a specific Post Type

Set up an Email Custom field type (Mandatory) and a corresponding condition rule.

You can apply Post, ACF, Metabox, JetEngine, Pods, and Toolset Custom field.

Complete the email data input for all posts of this Post Type.

Step 2: Create your own form by Piotnet Forms

#8 How do redirect data to another page?

You can enter this in the redirect within submit button: http://your site URL/?a=[field id=“abcd”] (if you have multiple fields, you can add “&”)

In the form that you want to get data. You create a field and add dynamic field value to get the value of the shortcode

E.g. You want to get parameter value from URL

Set up this format in default value {{request | parameter:a}}

#9 How to set Age Limit for any element in forms?

There are some pro features that we apply in this tutorial:
1. Image Select Fields
2. Date Field
3. Calculated Field
4. Conditional Logic

By setting the minimum age to 18, you probably limit the responses from children or teenagers.
On the other hand, you can classify options depending on age levels.
