WPML translate Caldera Forms forms

To translate Caldera Forms forms using WPML, you can use the icl_register_string function provided by WPML. This function allows you to register strings for translation and make them available for translation in the WPML translation interface.

Here’s an example code snippet that demonstrates how to translate Caldera Forms forms using WPML:

/**
 * Register Caldera Forms strings for translation with WPML.
 */
function wpsnippets_register_caldera_forms_strings() {
    if (function_exists('icl_register_string')) {
        // Replace 'my_form_id' with the ID of your Caldera Forms form.
        $form_id = 'my_form_id';

        // Get the form object.
        $form = Caldera_Forms_Forms::get_form($form_id);

        // Loop through the form fields.
        foreach ($form['fields'] as $field) {
            // Register each field's label for translation.
            if (!empty($field['label'])) {
                icl_register_string('Caldera Forms', $field['label'], $field['label']);
            }

            // Register each field's description for translation.
            if (!empty($field['description'])) {
                icl_register_string('Caldera Forms', $field['description'], $field['description']);
            }

            // Register each field's placeholder for translation.
            if (!empty($field['placeholder'])) {
                icl_register_string('Caldera Forms', $field['placeholder'], $field['placeholder']);
            }
        }
    }
}
add_action('init', 'wpsnippets_register_caldera_forms_strings');

In this code snippet, we define a custom function wpsnippets_register_caldera_forms_strings that is hooked to the init action. Inside the function, we check if the icl_register_string function exists (provided by WPML). Then, we specify the ID of the Caldera Forms form we want to translate.

We retrieve the form object using the get_form method of the Caldera_Forms_Forms class. Then, we loop through each field of the form and register its label, description, and placeholder for translation using the icl_register_string function.

By registering these strings, WPML will make them available for translation in the WPML translation interface, allowing you to translate the form labels, descriptions, and placeholders into different languages.

Remember to replace 'my_form_id' with the actual ID of your Caldera Forms form.

This code snippet can be useful when you want to translate Caldera Forms forms using WPML, ensuring that all form elements are properly translated for multilingual websites.

Examples

Example 1: Translating Caldera Forms using WPML

This example demonstrates how to translate Caldera Forms using the WPML plugin. The code snippet below shows how to register the form for translation and how to display the translated form on the front-end.

function wpsnippets_translate_caldera_forms() {
    if ( function_exists( 'icl_register_string' ) ) {
        $form_id = 'CF_FORM_ID'; // Replace with the ID of your Caldera Form
        $form_title = 'CF_FORM_TITLE'; // Replace with the title of your Caldera Form

        // Register the form for translation
        icl_register_string( 'Caldera Forms', 'Form: ' . $form_title, Caldera_Forms::get_form( $form_id ) );

        // Display the translated form
        echo do_shortcode( '[caldera_form id="' . $form_id . '"]' );
    }
}
add_action( 'wp', 'wpsnippets_translate_caldera_forms' );

Explanation: The wpsnippets_translate_caldera_forms function checks if the WPML plugin is active and registers the Caldera Form for translation using the icl_register_string function. The form ID and title are provided as parameters. Then, the translated form is displayed on the front-end using the do_shortcode function with the [caldera_form] shortcode.

Example 2: Translating Caldera Forms dynamically

This example demonstrates how to dynamically translate Caldera Forms based on the current language using the WPML plugin. The code snippet below shows how to retrieve the translated form based on the current language and display it on the front-end.

function wpsnippets_translate_caldera_forms() {
    if ( function_exists( 'icl_object_id' ) ) {
        $form_id = 'CF_FORM_ID'; // Replace with the ID of your Caldera Form

        // Get the translated form ID based on the current language
        $translated_form_id = icl_object_id( $form_id, 'caldera_forms', true );

        // Display the translated form
        echo do_shortcode( '[caldera_form id="' . $translated_form_id . '"]' );
    }
}
add_action( 'wp', 'wpsnippets_translate_caldera_forms' );

Explanation: The wpsnippets_translate_caldera_forms function checks if the WPML plugin is active and retrieves the translated form ID based on the current language using the icl_object_id function. The original form ID is provided as the first parameter, and the second parameter specifies the object type. Then, the translated form is displayed on the front-end using the do_shortcode function with the [caldera_form] shortcode.

Example 3: Translating Caldera Forms programmatically

This example demonstrates how to programmatically translate Caldera Forms using the WPML plugin. The code snippet below shows how to retrieve the translated form HTML based on the current language.

function wpsnippets_translate_caldera_forms() {
    if ( function_exists( 'icl_t' ) ) {
        $form_id = 'CF_FORM_ID'; // Replace with the ID of your Caldera Form

        // Get the translated form HTML based on the current language
        $translated_form_html = icl_t( 'Caldera Forms', 'Form: ' . $form_id, Caldera_Forms::render_form( $form_id ) );

        // Display the translated form
        echo $translated_form_html;
    }
}
add_action( 'wp', 'wpsnippets_translate_caldera_forms' );

Explanation: The wpsnippets_translate_caldera_forms function checks if the WPML plugin is active and retrieves the translated form HTML based on the current language using the icl_t function. The translation context is specified as the first parameter, which includes the form ID. The original form HTML is provided as the third parameter. Then, the translated form is displayed on the front-end.
