I want to add an icon in title posts only in posts with specific tag.

Is this possible?

I've already tried these codes, but they didn't solve my problem:

Approach #1

if (is_tag('162')) {
    function new_title( $title ) {
        $new_title = 'icon-url' . $title;
        return $new_title;
    }
    add_filter( 'the_title', 'new_title' );
}

Approach #2

add_filter( 'the_title', 'modify_post_title' );
function modify_post_title( $title ) {
    if ( is_tag('162') && $title == 'Existing Title' )
        $title = '<span>Existing</span> Title';
    return $title;
}

    return $title;
}

• OK, and where exactly should that icon be visible? On single post only? On all archive pages? – Krzysiek Dróżdż Commented Nov 18, 2018 at 19:42

The problem with your first approach is that you check conditional tags too early. is_tag will work only after the $wp_query is computed, so there is no point in checking it directly in functions.php file.

And there is one more problem with both approaches - you use wrong conditional tag...

is_tag checks if a Tag archive page is being displayed... So it's not what you're looking for.

And here's a solution:

function add_something_to_post_title( $title ) {
    if ( has_tag( 162 ) ) {
        $title = 'something ' . $title;
    }
    return $title;
}
add_filter( 'the_title', 'add_something_to_post_title' );

I want to add an icon in title posts only in posts with specific tag.

Is this possible?

    }
    add_filter( 'the_title', 'new_title' );
}

Approach #2

add_filter( 'the_title', 'modify_post_title' );
function modify_post_title( $title ) {
    if ( is_tag('162') && $title == 'Existing Title' )
        $title = '<span>Existing</span> Title';
    return $title;
}
