How to add a sign-up checkbox to my Contact Form 7 form?

Use the following shortcode in your CF7 form to display a newsletter sign-up checkbox.

The form shows a success message but subscribers are not added to my list(s)?

If the form shows a success message, there is no doubt that the sign-up request succeeded. Mailchimp could have a slight delay sending the confirmation email though, please just be patient and make sure to check your SPAM folder.

When you have double opt-in disabled, new subscribers will be seen as imports by Mailchimp. They will not show up in your daily digest emails or statistics. We always recommend leaving double opt-in enabled.

How can I style the sign-up form?

You can use custom CSS to style the sign-up form if you do not like the themes that come with the plugin. The following selectors can be used to target the various form elements.

You can add your custom CSS to your theme stylesheet or (easier) by using a plugin like Simple Custom CSS

Conditional Fields for Contact Form 7

Description

This plugin adds conditional logic to Contact Form 7.

If you edit your CF7 form, you will see an additional tag called « Conditional fields Group ». Everything you put between the start and end tag will be hidden by default.
After you have added the field group(s), click Save and go to the « Conditional fields » tab to create one or more conditions that will make the group(s) appear.

How to use it

Main/ New features

Support for required fields

Required fields can be used inside hidden groups without causing validation problems.

Hide/show info in emails based on what groups are visible

Conditional groups can now be added to the emails as well.
Just wrap the content with [group-name] . [/group-name] tags.

Groups can be nested

Groups can be nested, both in the form and in the email

Advanced users can code up the conditions as plain text instead of using the select boxes, using the import/export feature.

Captures d’écran

  • Conditional fields in action
  • Defining rules to show/hide groups of input elements in the backend interface

Installation

Email message is not showing the correct values / Wrong values are submitted

All field names should be unique

Even though your fields might never show up at the same time, it is still important to realize that WPCF7CF will not remove the fields, it merely hides them. So all fields will be submitted when the form is sent. Because of this no two fields can have the same name.

Incorrect form (2 input elements having the same name « a »):

Correct form (all groups and fields have unique names):

All my groups show up all the time and never get hidden.

Reason #1: Javascript error
Check your browser console (F12) for any javascript errors. WPCF7CF loads it’s scripts at the bottom of the HTML page, so if some javascript error gets triggered before that, the code will not be executed in most browsers.
Before reaching out to the support forum try to determine which plugin or theme is causing the problem, by gradually disabling plugins and changing theme.
