Repeater

Use a Repeater field to add a group of fields any number of times. This field allows users to click an Add button to add another group of fields. This field is incredibly useful if you would like users to add details about multiple items in a form. This feature is commonly used when adding information for multiple individuals, such as children, in a form.

Standard Field Options

A Repeater field has the following standard options:

• Field Key
• CSS Layout Classes
• Label Position
• Visibility
• Conditional logic

Field-specific options

Set up a Repeater Field

1. Add a Repeater field by clicking on Repeater in the Fields Panel (in the right sidebar).
   

2. Drag and drop the field(s) that you would like into the Repeater.
   
3. Now you can customize the layout of the repeat rows or change the repeat buttons.

Repeater styling

To customize the default styling for Repeater fields, go to Formidable → Styles → Repeater Fields. Select the icons and icon color that you would like to use for your add/remove buttons.

Repeater button color

To customize the Add/Remove button colors, go to Formidable → Styles → Custom CSS page and add the following CSS. You may adjust the background-color and border-color as needed.

.frm_repeat_sec .frm_button {
    background-color: #5bcd5d !important;
    border-color: #5acc5c !important;
}

Repeater button order

To customize the order of the repeater buttons, go to Formidable → Styles → Custom CSS page and add the following CSS.

.frm_repeat_buttons.frm {
  direction: rtl;
}

Add columns in a repeater

Since section headings can't be used inside a repeater, you could create a two-column layout by following the steps below:

1. If you want to create a title similar to a Section Heading field, you can add two HTML fields for each column inside a repeater.

   <h3>Section Title</h3>

2. In the CSS layout classes box, insert frm_first frm_half for the first HTML field and frm_half for the second HTML field.
3. Add the other fields that you want in the first column below the HTML field. Set the CSS layout class to frm_first frm_half.
4. Add the fields that you want in the second column below the HTML field. Set the CSS layout class to frm_half.
   

Note: This can also be done without the HTML field, if you don't want a heading title.

Get the total of the values of a Repeater field

To get a total of the values in a field in a Repeater, you can:

1. create a field outside of the Repeater to hold the total
2. in the Dynamic default value box, check the Calculations checkbox
3. in the Calculations box, put the [id] or [key] of the field inside the Repeater that you want to total

The values in the field in the Repeater will be added together automatically. If the values in the Repeater are words instead of numbers, you can check the text calculations checkbox, too. The total field will contain a comma-separated list of the values in the field in the Repeater.

Calculate the number of rows in a repeater

To calculate the number of rows in a repeater, follow the steps below:

1. Inside the repeater, add a hidden field to hold the row number.
   
   In the Default value box, set the default value to 1.
   
2. Outside the repeater, add a text or number field to hold the total number of rows. In the Default value (Calculations) box, insert the Hidden field ID.
   

The values in the hidden field in the Repeater will be added together automatically to calculate the number of rows.

Displaying Repeater Fields

In emails and Views, you'll see values from Repeater fields grouped by field, rather than by row:

Name: John Smith, Julie Roberts, Rob Darlington
Meal: Pepperoni pizza, Fettucine alfredo, Pepperoni pizza
Drink: Dr. Pepper, Water, Coca Cola

You may use the [foreach] shortcode in a View or an email to group values from a Repeater by row. Alternatively, you may create a View from a Repeater field. A View from a Repeater provides ordering and filtering options that the [foreach] shortcode, in a View from the main form, does not. A View from a Repeater could be standalone or could be nested inside of a View from the main form.

Display data grouped by row

If you would like to display the data from a Repeater field grouped by row, like this:

John Smith: Pepperoni pizza, Dr. Pepper
Julie Roberts: Fettucine alfredo, Water
Rob Darlington: Pepperoni pizza, Coca Cola

you can use the foreach shortcode like this:

[foreach 100]
[101]: [102], [103]
[/foreach]

Replace 100 with the field ID of your Repeater field. Replace 101, 102, and 103 with the field IDs that are inside of the Repeater.

Display data in a table

You can also use the foreach shortcode to display the repeater fields in a table:

Use the code below to create a table with the foreach shortcode:

<table>
<tr>
<th>Column 1</th>
<th>Column 2</th>
<th>Column 3</th>
</tr>
[foreach 100]
<tr>
<td>[101]</td>
<td>[102]</td>
<td>[103]</td>
</tr>
[/foreach 100]
</table>

Replace 100 with the field ID of the Repeater field. Replace 101, 102, and 103 with the field IDs that are inside of the Repeater.

Limitation

Repeaters are not designed to allow form actions to trigger by row.

Review before submit

Note: Custom code is no longer needed. Please use a Summary field to review before submit.

Other field types are much simpler to display in an HTML field on the last page of your form. But repeater fields need a bit of extra code. Use [frm-repeat-post section_id=25 field_ids='26,27'] in the HTML field at the end of your form. Replace 25 with the ID of your repeater field, and 26,27 with the fields inside of it.

add_shortcode('frm-repeat-post', 'frm_repeat_post');
function frm_repeat_post( $atts ) {
	$content = '';
	$field_ids = explode( ',', $atts['field_ids'] );
	if ( ! isset( $_POST['item_meta'][ $atts['section_id'] ] ) ) {
		return $content;
	}

	foreach ( (array) $_POST['item_meta'][ $atts['section_id'] ] as $row ) {
		if ( $key === 'form' || $key === 'row_ids' ) {
			continue;
		}
		foreach ( (array) $field_ids as $field_id ) {
			if ( is_array( $row[ $field_id ] ) ) {
				$content .= ' ' . sanitize_text_field( implode( ', ', $row[ $field_id ] ) ) . '
';
			} else {
				$content .= $row[ $field_id ];
			}
		}
		$content .= '<br/>';
	}
	return $content;
}
