WordPress WP Forms A/B testing

Test form variations for optimization.

To perform A/B testing on WP Forms, you can use the WordPress Transients API to store and retrieve the form variations. Here’s an example code snippet that demonstrates how to implement A/B testing for WP Forms:

/**
 * A/B testing for WP Forms
 */
function wpsnippets_wpforms_ab_testing( $form_id ) {
    // Check if A/B testing is enabled
    if ( ! wpsnippets_is_ab_testing_enabled() ) {
        return $form_id;
    }

    // Get the form variations
    $variations = wpsnippets_get_ab_testing_variations();

    // Get the current variation
    $current_variation = wpsnippets_get_current_ab_testing_variation();

    // Check if the current variation is valid
    if ( ! isset( $variations[ $current_variation ] ) ) {
        return $form_id;
    }

    // Get the form ID for the current variation
    $variation_form_id = $variations[ $current_variation ];

    // Check if the form ID for the current variation is valid
    if ( ! wpforms()->form->get( $variation_form_id ) ) {
        return $form_id;
    }

    // Return the form ID for the current variation
    return $variation_form_id;
}
add_filter( 'wpforms_form_id', 'wpsnippets_wpforms_ab_testing' );

This code snippet hooks into the wpforms_form_id filter and checks if A/B testing is enabled. If it is, it retrieves the form variations and the current variation. It then checks if the current variation is valid and returns the form ID for the current variation. If A/B testing is not enabled or the current variation is invalid, it returns the original form ID.

To use this code snippet, you need to replace wpsnippets_is_ab_testing_enabled(), wpsnippets_get_ab_testing_variations(), and wpsnippets_get_current_ab_testing_variation() with your own functions that handle A/B testing settings and logic.

This code snippet can be useful when you want to test different variations of a WP Forms form and track their performance. It allows you to easily switch between form variations based on A/B testing settings.

Examples

Example #1: A/B Testing Different Form Designs

This use case demonstrates how to perform A/B testing on different form designs using WP Forms.

function wpsnippets_ab_test_form_design( $form_id ) {
    if ( is_user_logged_in() && current_user_can( 'manage_options' ) ) {
        $form_design = get_user_meta( get_current_user_id(), 'wpsnippets_form_design', true );
        if ( $form_design === 'design_a' ) {
            // Display form design A
            echo do_shortcode( '[wpforms id="' . $form_id . '"]' );
        } elseif ( $form_design === 'design_b' ) {
            // Display form design B
            echo do_shortcode( '[wpforms id="' . $form_id . '"]' );
        } else {
            // Display default form design
            echo do_shortcode( '[wpforms id="' . $form_id . '"]' );
        }
    } else {
        // Display default form design
        echo do_shortcode( '[wpforms id="' . $form_id . '"]' );
    }
}

This code example demonstrates how to perform A/B testing on different form designs. It checks if the user is logged in and has the capability to manage options. If the user has selected a specific form design (design A or design B) in their user meta, the corresponding form design is displayed using the WP Forms shortcode. If no specific form design is selected, the default form design is displayed.

Example #2: Tracking Form Submissions for A/B Testing

This use case demonstrates how to track form submissions for A/B testing purposes using WP Forms.

function wpsnippets_track_form_submissions( $entry_id, $form_data ) {
    $form_id = $form_data['id'];
    $form_design = get_user_meta( get_current_user_id(), 'wpsnippets_form_design', true );

    if ( $form_design === 'design_a' ) {
        // Track form submission for design A
        // ...
    } elseif ( $form_design === 'design_b' ) {
        // Track form submission for design B
        // ...
    } else {
        // Track form submission for default design
        // ...
    }
}
add_action( 'wpforms_process_complete', 'wpsnippets_track_form_submissions', 10, 2 );

This code example demonstrates how to track form submissions for A/B testing purposes. The wpforms_process_complete action hook is used to trigger the tracking function after a form submission. The function retrieves the form ID and the selected form design from the user meta. Based on the form design, the corresponding tracking code can be implemented.

Example #3: Displaying A/B Test Results

This use case demonstrates how to display A/B test results for different form designs using WP Forms.

function wpsnippets_display_ab_test_results( $form_id ) {
    $form_design_a_submissions = get_form_submissions_count( $form_id, 'design_a' );
    $form_design_b_submissions = get_form_submissions_count( $form_id, 'design_b' );

    echo 'Form Design A Submissions: ' . $form_design_a_submissions;
    echo 'Form Design B Submissions: ' . $form_design_b_submissions;
}

This code example demonstrates how to display A/B test results for different form designs. The get_form_submissions_count() function is a custom function that retrieves the number of form submissions for a specific form design. The function is called twice, once for design A and once for design B, and the results are displayed using echo.
