HI,

First, a big congratulation for this huge and wonderful plugin for WP ! 🙂
Thanks to authors!

Well, after some several time elapsed on one of my research…
I need some help, I hope you’ll help me on this issue

I created a simple form with a checkbox control
with these values:

"en:english"
"fr:french"

and in my PHP Code, I would like to test, but it seems doesn’t work 🙁

This my code :

<?php if ((get_field('language') == 'en')) { echo "ENGLISH Flag icon"} else {} ?>
<?php if ((get_field('language') == 'fr')) { echo "FRENCH Flag icon"} else {} ?>

Result: Array text or nothing appears 🙁

The goal is to display or not a flag icon, if I check the option in ACF…

Thanks alot by advance,

Regards,

Nico.

@mikosworld,

Try this:

$lang = get_field('language');
	
if ( 'en' === $lang ) { 
	echo "ENGLISH Flag icon"; 
}
elseif ( 'fr' === $lang ) { 
	echo "FRENCH Flag icon"; 
}

Hi @mikosworld

You can use this code to test the value. That way you know what you are working with:

<?php 

$lang = get_field('language');

echo '<pre>';
	var_dump( $lang );
echo '</pre>';
die;

?>

ok Elliot, thanks but…
it gets this :

array(2) {
  [0]=>
  string(2) "en"
  [1]=>
  string(2) "fr"
}

How tests “en” checkbox is checked and test “fr” is checked ?

{

}

?>
