First of all, I hope you have created a child theme already. If you haven’t here is how to <a href="https://codex.www.ads-software.com/Child_Themes" rel="noopener" target="_blank">Create a Child Theme</a>
.
WordPress by default uses a file called page.php
for displaying page contents for homepage, front page and post pages. To display category hyperlink you need to use built in WordPress function the_category(). This will display the category name/s associated with your post and create hyperlinks for each so that users can click on a category to go to another page with list of posts which are under that category.
According to WordPress template hierarchy, post detail page can use a file called single.php
which you can modify according to your requirement without hampering home page or front page layouts. Good news is Rambo already provides a separate single.php
for you!
So I recommend you to copy single.php
from Rambo’s original theme folder inside your child theme folder. Then after line number 20, add the following code: <?php the_author();?>
. That’s it! You should be able to see the categories coming up with links to their respective pages.
Remember, the categories will come up as list items by default. So you need to make adjustments in your CSS in order to make them inline with other elements.
Let me know if this helps!
