Replacing underscores by hyphens in hreflang

    I am currently running a WP multisite with two different versions that I want to show different “language-country” hreflangs for in my header. I managed to add the following code to my functions.php file in order to make the country code appear in the hreflang as well:

    Code added to functions.php

    /**
 * @param string $language
 * @return string
 */
function my_msls_head_hreflang( $language ) {
	if ( 'en' == $language ) {
		$language = 'en-us';
	}
	return $language;
}
add_filter( 'msls_head_hreflang', 'my_msls_head_hreflang' );

    Now the hreflang tags shown in my header use underscores (_) instead of hyphens (-). However, they need to be hyphens as this is the only format search engines will recognize.

    Now my hreflangs look like this:

    <link rel="alternate" hreflang="en_US" href="http://example.com/" />
<link rel="alternate" hreflang="en_GB" href="http://example.com/gb/" />

    While they should look like this:

    <link rel="alternate" hreflang="en-US" href="http://example.com/" />
<link rel="alternate" hreflang="en-GB" href="http://example.com/gb/" />

    I have my WPLANG in my multisite settings configured with underscores: “en_US” for instance. Changing this however doesn’t seem to make a difference.

    Any thoughts?

    Hi,

    I’m pretty sure that $language is not set to ‘en’. Please check first what you have here. I think it will be something like ‘en_US’ or ‘en_GB’ in your case.

    To change just the underscores to hyphens here I would do something like this:

    /**
 * @param string $language
 * @return string
 */
function my_msls_head_hreflang( $language ) {
	return str_replace( '_', '-', $language );
}
add_filter( 'msls_head_hreflang', 'my_msls_head_hreflang' );

    Cheers,
    Dennis.

    Hi Dennis,

    Big thanks for replying so quickly! Replacing my code with the one you provided did the trick for me. The hreflangs are now showing “language-country” with the hyphen. I’m glad it’s working, thanks! 🙂
