Adds repeatable groups of fields to Contact Form 7.

Description

This plugin adds repeatable groups of fields to Contact Form 7.

NOTE: Tested with Contact Form 7 5.1.6.

Usage

Form tab

Wrap the desired fields with [field_group your_group_id_here][/field_group]. The shortcode accepts additional parameters, in WP shortcode format and in CF7 fields parameters format as well.

Example:

[field_group emails id="emails-groups" tabindex:1]
	<label>Your Email (required)[email* your-email]</label>
	[radio your-radio use_label_element default:1 "radio 1" "radio 2" "radio 3"]
	[select* your-menu include_blank "option1" "option 2"]
	[checkbox* your-checkbox "check 1" "check 2"]
[/field_group]

Mail tab

In the mail settings, wrap the fields with your group id. You can use the [group_index] tag to print the group index and an additional __<NUMBER> to print a field at a specific index.

Example:

The second email entered by the user was: [your-email__2]

These were the groups:
[emails]
GROUP #[group_index]
	Checkbox: [your-checkbox]
	E-mail: [your-email]
	Radio: [your-radio]
	Select: [your-menu]
[/emails]

Customizing the add and remove buttons

You can add filters to your theme to customize the add and remove buttons.

Example

// In your theme's functions.php
function customize_add_button_atts( $attributes ) {
  return array_merge( $attributes, array(
    'text' => 'Add Entry',
  ) );
}
add_filter( 'wpcf7_field_group_add_button_atts', 'customize_add_button_atts' );

The available filters are:

wpcf7_field_group_add_button_atts

Filters the add button attributes.

Parameters:

• $attributes: Array of attributes for the add button. Keys:
• additional_classes: css class(es) to add to the button

Return value: array of button attributes

wpcf7_field_group_add_button

Filters the add button HTML.

Parameters:

Frequently Asked Questions

Can I change the add/remove buttons?

Yes. You can use wpcf7_field_group_add_button_atts, wpcf7_field_group_add_button, wpcf7_field_group_remove_button_atts, and wpcf7_field_group_remove_button filters, as shown above. Props to @berniegp.

How can I display the group index number in the form?

You'll have to use the wpcf7-field-groups/change jQuery event.

In the Form tab, add an element to hold the group index. In this example, it'll be a <span> with the group-index class:

[field_group emails id="emails-groups" tabindex:1]
	<p>Group #<span class="group-index"></span></p>
	<label>Your Email (required)[email* your-email]</label>
	[radio your-radio use_label_element default:1 "radio 1" "radio 2" "radio 3"]
	[select* your-menu include_blank "option1" "option 2"]
	[checkbox* your-checkbox "check 1" "check 2"]
[/field_group]

And then you’ll have to add this to your JavaScript code:

jQuery( function( $ ) {
	$( '.wpcf7-field-groups' ).on( 'wpcf7-field-groups/change', function() {
		var $groups = $( this ).find( '.group-index' );
		$groups.each( function() {
			$( this ).text( $groups.index( this ) + 1 );
		} );
	} ).trigger( 'wpcf7-field-groups/change' );
} );

You can add that JS through your theme OR use some plugin like Simple Custom CSS and JS.
