Change “No Comments” link to “My String” on Blog Post (Find Snippet in Code or use CSS, PHP Solution) [closed]

Try this. You can add this snippet in a child theme functions.php file.

Replace “Your No Comments String” with whatever you want.

/*
 * @param string $output A translatable string formatted based on whether the count
 *                       is equal to 0, 1, or 1+.
 * @param int    $number The number of post comments.
 * @return string $output
 */
function richards_no_comment_string( $output, $number ){

    if( $number === 0 ){
        
        $output = __( 'Your No Comments String' );
    }

    return $output;
}
add_filter('comments_number', 'richards_no_comment_string', 20, 2);

For the free Sinatra theme, which uses a theme specific function to output that text, the customization would be to add to the child theme this function:

    function sinatra_entry_meta_comments() {
    
            $icon = sinatra()->icons->get_meta_icon( 'comments', sinatra()->icons->get_svg( 'message-square', array( 'aria-hidden' => 'true' ) ) );
    
            if ( ! post_password_required() && ( comments_open() || get_comments_number() ) ) {
                echo '<span class="comments-link">';
    
                comments_popup_link( wp_kses_post( $icon ) . esc_html__( 'Leave a Comment', 'sinatra' ), wp_kses( $icon, sinatra_get_allowed_html_tags( 'post' ) ) . esc_html__( '1 Comment', 'sinatra' ), wp_kses( $icon, sinatra_get_allowed_html_tags( 'post' ) ) . esc_html__( '% Comments', 'sinatra' ), 'comments-link' );
    
                echo '</span>';
    }
}

Tested and confirmed working.
