Using the Post Grid Combo plugin, you can easily query posts by author for Post Grid or Post Grid – Filterable Gutenberg blocks.
To begin, insert the “Post Grid” or “Post Grid – Filterable” block.
From the List View make sure you’ve selected Post Query nested block. This selection is important to access all the available block settings for “Post Query”.
Now under Query Post => Add Query Params select the Author Name option. You can also query from the Author ID.
Here you can see I’m trying to query posts by passing the author name Raju. And the results are showing as expected.
That’s how you can query posts by Author Name and ID. If you still need help, please create a support ticket on our forum.
