Pre-filling or Auto-Populating form fields is a time-saving feature in Pabbly Form Builder. If you already know the answers that your users going to fill, you can Pre-fill those fields before sharing the form with your users.
Auto-Populate Form Fields through URL
Every form field has a unique pre-fill key which is available right away when you click on a particular field. You can use this key in your form URL to pass a value for that field.
You can use this key to pre-fill a field.
How to do that?
- Copy the pre-fill key of your selected field.
- Put a “?” after your form URL and paste that key and equal to value.
For Example, your form URL will look like this: https://forms.pabbly.com/form/share/baSW-425436?rj43L=1234
You can pre-fill multiple fields by adding “&” between the values.
For example; https://forms.pabbly.com/form/share/baSW-425436?rj43L=1234&[email protected]
Pre-selecting multiple choice fields
Pre-selecting multiple-choice fields like radio/checkbox/ dropdown is very easy. Just pass the option name in the URL.
For example; form_url?key=First Choice
