What It Does

This plugin allows for multilingual management of Contact Form 7 using the Polylang plugin. It is developed as an extension of the CF7 Smart Grid-layout plugin, which must be installed for functionality. You can use a single CF7 form shortcode for all translations, simplifying the management of multilingual forms.

The plugin introduces form keys, allowing you to identify forms by their keys rather than IDs, which can change between servers. This feature ensures that your forms remain consistent during migration from local to production environments.

Follow the installation instructions carefully, especially regarding Polylang settings. This plugin works seamlessly with multisite installations and supports various CF7 extensions for enhanced functionality.

FAQ

If you found that you installed the plugin correctly and are able to manage your forms using the polylang language columns, then it is likely that the language your have selected does not have a translation for the Contact Form 7. You can visit the following translation project page to see the status of the translation CF7 for your language.

In order to ensure the correct translation is shown in your template page, you need to make sure you get the translated id $trans_form_id in your do_shortcode function call,

do_shortcode([contact_form_7 id="{$trans_form_id}"]);

You have Polylang setup using a default language and a set of additional languages. When Polylang translates a custom post (such as the wpcf7 post), it keeps track of all translations using the post ID, by pairing the primary language post ID with its corresponding translated post IDs which is what the CF7 Polylang Extension does for you.

So you need to search your translation using the primary language post ID, to do this you need to make use of the Polylang functions,

$form_id = 252; //assuming this is your default language form ID $default_lang = pll_default_language('slug'); $current_lang = pll_current_language('slug); //the current language your page is being viewed as if($current_lang != $default_lang){   $form_id = pll_get_post($form_id, $current_lang);   if(empty($form_id)){ //if a translation does not exists     $form_id = 252; //show the default form   } } //display your form echo do_shortcode('[contact-form-7 id=”'.$form_id.'″]');

The cf7 plugin provides a special mail tag [_site_url] which prints the site url. However, this is not one of the filtered polylang links. Therefore as of v2.3 this plugin now has the [_home_url] mail tag that you an use in your mail body and which will show the home url of site from which it was submitted from.

Alternatively, you could also construct your own special mail tag, such as [_lang] using the follwoing code in your functions.php file,

add_filter( 'wpcf7_special_mail_tags','my_cf7_mail_tag', 10,3); function my_cf7_mail_tag($output, $name, $html ) {   if ( '_lang' == $name ) {     $filter = $html ? 'display' : 'raw';     $output = $_POST['_wpcf7_lang'];   }   return $output; }

If you have a plugin which has specific translation strings used in CF7 forms, you need to tell the CF7 Polylang plugin to load the resources for the required locale. To do this use the following filter hook,

add_filter('cf7pll_load_plugin_translation_resource', 'add_translation_resource'); function add_translation_resource($plugin_translation){   //the $plugin_translation is an array into which you need to add your plugin slug and version number.   $plugin_translation['my-plugin-slug']=$version.   return $plugin_translation; }

this filter should be used by plugin developers to ensure their plugin translation resources are loaded.
