language switcher in menu creating style for width and height

Hello,

You can use the filter pll_get_flag. You’ll receive the complete img tag, so you can easily modify it to remove or add anything you want. See https://polylang.pro/doc/filter-reference/#pll_get_flag

Thanks for that.

However, I am not sure where to add the code. It says not to use the theme functions.php which is where I normally would add code and I do not have any idea about adding a plugin or mu-plugin.

Do I need to add a new plugin or mu-plugin and if so how? or can I add it somewhere else? How? Where?

Thanks.

Yes. A mu-plugin is perfect for this case.

It’s as simple as using a functions.php Create the folder mu-plugins in wp-content. Add a file, let say flags.php in this folder. Add your code in this file. WordPress will automatically execute your code.

Thank you.

However, I have created the mu-plugins folder in wp-content and created the flags.php in the folder.

I have added the following code but in adds to the section before the DOCTYPE statement and does not change the actual code.

<php?

add_filter( 'pll_custom_flag', 'pll_custom_flag', 10, 2 );

function pll_custom_flag( $flag, $code ) {
$flag['url'] = content_url( "/polylang/{$code}.svg" );
$flag['width'] = '';
$flag['height'] = '';
$flag['src'] = '';
return $flag;
}

?>

Can someone please tell me what I am doing wrong?

Have managed to get it to not show at the beginning but does not work.
