123FormBuilder is a free form builder with conditional logic functionality, allowing its users to change the behavior of their web forms based on the input provided by their respondents.
With conditional logic you can change the behavior of your form based on user input and make your online forms more dynamic. At 123FormBuilder you can create complex and advanced rules that affect the behavior of your online forms. There are three types of rules you can create:
All of the three types of rules are located in the Form Settings → Rules section of your form, under separated tabs.
Field Rules affect the behavior of your online form while it is being used. Here you can show or hide certain fields based on the input given by your submitters. These type of rules are applied in real-time, while the end users fill in the the online form.
Autoresponder Rules trigger a specific autoresponder when one or more conditions are met. These type of rules apply after the end user submitted the form.
Form Rules redirect end users to a certain web page that you have provided when some specific conditions are met. For example: You can use this option to redirect users to a different version of your website depending on the language they have selected on the form. Form rules apply after the form is submitted.
Besides form fields, you can also include the language field (if using translations) and the quiz score (for quiz forms) in any type of rule.
Important: Separate rules that use the same field will not work on the form. This is due to a conflict issue. We recommend you create advanced rules with several conditions and subrules in the same rule, if needed.
If you want to use field rules, autoresponder rules or form rules – tick the option Enable rules for this form. It’s located under the Field Rules tab and applies to all three type of rules used.
To create a rule, click on the Add Rule button and a line will be displayed below. Use the first dropdown to select the field, the second to select the operator and the last field to conclude the condition. For input fields, you need to type a value. For choice fields such as radio buttons or check boxes, you have a dropdown with the predefined values is checked and is not checked.
The grey plus button on the right creates a new condition that is linked to the previous one through connectors. Conditions from the same rule are linked either with the connector AND or OR. The grey button will appear next to the last condition of each rule or subrule.
When you have edited all the conditions you need for your rule, click on Continue to set up the behavior of your rule. Afterwards, hit Finished to add it to your online form.
If you want to edit a condition from your rule, hover over it and press the button Edit or Delete if you want to delete it completely. Next to these buttons you’ll find the Subrule button that creates a subrule within the respective condition.
If you want to delete a subrule, click on the red cross from the top right side of the subrule layout.
To delete a rule, hover over the layout of the rule and tick the checkbox on the top right. Press Delete on top to delete it or Duplicate to make a copy of the rule. You can select several rules and delete or duplicate them at the same time. Use the Unselect rules button to clear all selections.
Use the search bar to find the rule you are after. Finally, use the Preview Form button to see how your rules apply to your online form.
