Button text to display postname dynamically

Hi,

My website is for an artist booking agency, which has many artists (each artist is a portfolio item). For each of the artists I currently have a button which says “book this artist”. Instead I would like the button text to dynamically display the artist name (which is the portfolio item title), for instance if the portfolio title is DJ XYZ, I would like the button to automatically display “Book DJ XYZ”.

How would I go about this?

Also, I am using the Advanced Custom Fields plugin. However if i try to put the shortcode to display the artist name in there it doesnt work (I think probably because it is a shortcode within a shortcode). So perhaps a better way would be to just dynamically call the portfolio item / post title.

Any advice or suggestions would be greatly appreciated

Thanks in advance
