How to edit meta info in homepage

Hi there,

you can use this filter to add the categories to the Header Entry Meta:

https://docs.generatepress.com/article/generate_header_entry_meta_items/#examples

I've read the link, where i add the code ?

Adding PHP: https://docs.generatepress.com/article/adding-php/

i've try with code snippet plugin.

Its work, but there are duplicate category info in homepage

And then, i want to make the structure of meta like this :

Category - Date - Author

the separator with strip symbol

up

You can unset the categories in the footer entry meta:

add_filter( 'generate_footer_entry_meta_items', function( $items ) {
    return array_diff( $items, [ 'categories' ] );
} );

For the separator, try this:

.entry-header .cat-links:after, 
.entry-header .posted-on:after {
    content: " - ";
}

For unset the categories in the footer entry, where is the php file code i changes ?

You can add it using the same method you used above: https://docs.generatepress.com/article/adding-php/
