I am trying to Show a BUTTON only if the wordpress post meta tag contains specific text.

strip_tags(get_the_term_list( $post->ID, 'posttype')

I have lot of tags in this posttypes tag for example- Hindi, English, Hindi-English, Maths, Hindi-Maths, Hindi-English-Maths.

I want to show this BUTTON for all posts if tag contains Hindi.

<button class="boxeedbk buttonbk">"CONTAINS HINDI as WELL"</button></a>

What statement could it be so I put in single.php worpdress theme.

Thank You
