Shortcode from a function not working

Question

I am trying to create a shortcode from a custom function in WP but it seems like I'm doing something wrong.

I have a function in child's theme function.php and add_shortcode code:

function uniquetestfunction() {
echo '<div class="my_class">Test Element</div>';
}
add_shortcode(‘uniqueshortcodename’,’uniquetestfunction’); 

Which should generate a shortcode [uniqueshortcodename]. I have done this with existing functions in different plugins and it worked fine.

But when added to a page, it's not rendering the function, just showing the shortcode as a text. Any ideas what I'm doing wrong?

I'm very new to PHP :) Thanks

If you refer to the documentation for add_shortcode, you need your function to return the content:

function uniquetestfunction($attributes) {
   return '<div class="my_class">Test Element</div>';
}
add_shortcode('uniqueshortcodename','uniquetestfunction');

You also used the wrong quotes in your add_shortcode line - stick with single ' or double " quotes.
