ok and if I dont put anything in the custom field will it show the original author name?

ok in the video you will see me creating a new post. I input the author name in the acf field at the bottom of the new post page. Once I hit publish I went to the front end homepage and the author name that I inputted showed correctly. But when I went to the individual post on the front end it didnt work. Instead it showed my name instead of the author name I put in the acf field. The only time I want the original author name to show is when a name isnt put in the acf field.

Ok I will make a video and send you the link.

Thank you

We are already using the single post author.

I understand that. But what if we don’t use the acf field and want it to be the default writer name. We only use that field when we want to reference a different author. So if we don’t put a name in the text field it wont show a name then if I did it the way you suggested?

This image shows the text field in the new post page.

When they enter the author name it show the custom author name on the post live page.

Instead it only show the custom author name on the home page and not on the post page. On the post page it only shows the author of the post.

We use the plugin for when we need to reference a different author.

How can I add screenshots. There is no upload on here.
