ACF Ninja Forms Field

This is an Advanced Custom Field custom field to select one or many Ninja Forms.

Compatibility

• ACF version 4 and up
• Ninja Forms version 2.9.X and up

Installation

This add-on can be treated as both a WP plugin or a theme include.

Plugin

1. Copy the 'acf-ninja-forms' folder into your plugins folder
2. Activate the Advanced Custom Fields: Ninja Forms Field plugin through the 'Plugins' menu in WordPress

Include

1. Copy the 'acf-ninja-forms' folder into your theme folder (can use sub folders). You can place the folder anywhere inside the 'wp-content' directory
2. Edit your functions.php file and add the code below (Make sure the path is correct to include the acf-ninja-forms.php file)

function my_register_fields() {
    include_once( 'acf-ninja-forms.php' );
}
add_action( 'acf/register_fields', 'my_register_fields' );

Using the field

The field lets you pick one or many fields.

The data returned is either a Form object or an array of Form objects.

If you have selected a single form and you want to display the form on the page, you can use:

Ninja Forms 3.X.X

<?php
$form = get_field( 'your_form_field' );
if ( class_exists( 'Ninja_Forms' ) ) {
    Ninja_Forms()->display( $form[ 'id' ] );
}
?>

Ninja Forms 2.9.X

<?php
    $form = get_field( 'your_form_field' );
    if ( function_exists( 'ninja_forms_display_form' ) ) {
        ninja_forms_display_form( $form[ 'id' ] );
    }
?>

You can find out more about the Ninja Forms methods to embed a form on a page in their documentation

If you are using the field to select multiple forms, you will have to iterate over the array. You can then use the form object as you like:

<?php
    $forms = get_field('your_forms');
    foreach( $forms as $form ){
        echo $form[ 'id' ];
    }
?>
