Changing the title of Wordpress Tag Pages

Question

I wish to change the title of Tags pages of my wordpress blog. What I want to do is to keep the Tag name as it's title only.

For example: If a tag name is "Wordpress Tag Pages Tutorial" then that tag should have the same title "Wordpress Tag Pages Tutorial" instead of "Blog Name - Wordpress Tag Pages Tutorial" so what to change in this code? I have tried but showing errors like only variables name in wordpress title.

<title>
<?php if (is_home () ) { bloginfo('name'); }elseif ( is_category() ) {
single_cat_title(); echo ' - ' ; bloginfo('name'); }
elseif (is_single() ) { single_post_title();}
elseif (is_page() ) { bloginfo('name'); echo ': '; single_post_title();}
else { wp_title('',true); } ?>

Answer 1

You're missing is_tag().

Example:

if ( is_tag() ) {
    $tag = single_tag_title("", false);
    echo $tag;
}

Answer 2

If there are any SEO plugins installed in the site, it will override the 'wp_title' function. So you can manage the title string in that plugin settings.

If there are no such plugins, you can use following code:

    add_filter('wp_title', 'hs_tag_titles',10);

function hs_tag_titles($orig_title) {

    global $post;
    $tag_title = 'Test Title';
    if ( is_tag() ) {
        return $tag_title;
    } else {
        return $orig_title;
    }
}
