Wordpress: Include variable in add_query_arg

Question

Using this:

echo add_query_arg( 'hello', '$var', get_permalink(9) );

On the following page (permalink(9)), when I

echo $_GET['hello'];

I get $var, not the contents of the variable.

Is there a way to make sure it's a string before I add it to add_query_arg?

Thanks!

Because you're passing it in using single quotes, which will not parse the variable. It's sending in a string "$var" instead of the actual variable.

Use no quotes and try again.

To check if it's a string, use is_string() to return a T/F value, and if true, execute.
