How to set the reCaptcha language?

PS
corrected

add_action( 'wpcf7_enqueue_scripts', 'custom_recaptcha_enqueue_scripts', 11 );

function custom_recaptcha_enqueue_scripts() {
    $current_lang = ICL_LANGUAGE_CODE;
	wp_deregister_script( 'google-recaptcha' );

	$url = 'https://www.google.com/recaptcha/api.js';
	$url = add_query_arg( array(
		'onload' => 'recaptchaCallback',
		'render' => 'explicit',
	 	'hl' => $current_lang ), $url );

	wp_register_script( 'google-recaptcha', $url, array(), '2.0', true );
}

Thanks for your plugin it works. Even with qtranslate. You have to set the parameter to:
[:en]en[:de]de[:es]es[:]

Then the recaptcha language will be adjusted to the current qtranslate language of your site. In my case, I have three language: english, german, and spanish.

Hi, Your code for WPML seems to work for 90% of the time, for us only the Dutch (Netherlands) part isn’t working, which is a bit odd and slightly annoying since a large part of the customer base is from the netherlands as well as the company behind the website.

Any clue why this isn’t working ? for the other 9 languages including Chinese, Russian, French and German it is working fine.

Hi,
my solution: put following code in your template functions.php to avoid problems after update. If you use polylang plugin like me, leave as it is, otherwise replace the pll_current_language() by your ‘language code’ or any variable detecting the current language.

/*wpcf7 recapcha hooks*/

function my_wpcf7_recaptcha_enqueue_scripts() {

$url = ‘https://www.google.com/recaptcha/api.js’;
$url = add_query_arg( array(
‘onload’ => ‘recaptchaCallback’,
‘render’ => ‘explicit’,
‘hl’ => pll_current_language()), $url );

wp_deregister_script(‘google-recaptcha’);
wp_register_script( ‘my-google-recaptcha’, $url, array(), ‘2.0’, true );
wp_enqueue_script( ‘my-google-recaptcha’ );

}

function my_wpcf7_recaptcha_callback_script() {

if ( ! wp_script_is( ‘my-google-recaptcha’, ‘enqueued’ ) ) {
return;
}

?>
<script type=”text/javascript”>
var recaptchaWidgets = [];
var recaptchaCallback = function() {
var forms = document.getElementsByTagName(‘form’);
var pattern = /(^|\s)g-recaptcha(\s|$)/;

for (var i = 0; i < forms.length; i++) {
var divs = forms[i].getElementsByTagName(‘div’);

for (var j = 0; j < divs.length; j++) {
var sitekey = divs[j].getAttribute(‘data-sitekey’);

if (divs[j].className && divs[j].className.match(pattern) && sitekey) {
var widget_id = grecaptcha.render(divs[j], {
‘sitekey’: sitekey,
‘theme’: divs[j].getAttribute(‘data-theme’),
‘type’: divs[j].getAttribute(‘data-type’),
‘size’: divs[j].getAttribute(‘data-size’),
‘tabindex’: divs[j].getAttribute(‘data-tabindex’),
‘callback’: divs[j].getAttribute(‘data-callback’),
‘expired-callback’: divs[j].getAttribute(‘data-expired-callback’)
});

recaptchaWidgets.push(widget_id);
break;
}
}
}
}
</script>
<?php
}

add_action( ‘wpcf7_enqueue_scripts’, ‘my_wpcf7_recaptcha_enqueue_scripts’ );
add_action( ‘wpcf7_enqueue_scripts’, ‘my_wpcf7_recaptcha_callback_script’ );

Hi takayuki,

Could you please get me how should i add filter to functions.php for render script

I’ve got also need to set the language per site language (multilanguage site).

Please add WordPress filter for reCAPTCHA api arguments.
Deregistering and registering the script again with custom argumets does the job but leaves more work to maintain a site.

Thanks
