Ask a question about pagination

This paging is based on the query condition of $name. I would like to ask if the link to the page number of this paging is hard-coded during the first query? For example, when clicking on the second page, the query condition $name was not submitted. If the following if judgment is used, wouldn't $name be empty? There is no way to click on the second page. Is it like what I said at the beginning that the URLs of all page numbers have been generated during the first query, so there is no need to query based on the query conditions?

$name = isset($_REQUEST['name'])? $_REQUEST['name'] : '';
$page = isset($_REQUEST['page'])? $_REQUEST['page'] : 1;

''.($i).''

Yes, it is generated on the first query

You can use paging controls.
