Build an HTML pagination bar based on the number of page to display, the
|
|
current page and the url to give to each page link.
|
|
|
|
C<$base_url> is the URL for each page link. The
|
|
C<$startfrom_name>=page_number is added at the end of the each URL.
|
|
|
|
C<$nb_pages> is the total number of pages available.
|
|
|
|
C<$current_page> is the current page number. This page number won't become a
|
|
link.
|
|
|
|
This function returns HTML, without any language dependency.
