1612 | * create the paginated links. The 'format' argument is then used for replacing |
1613 | * the page number. It is however, most likely and by default, to be used on the |
1614 | * archive post pages. |
1615 | * |
1616 | * The 'type' argument controls format of the returned value. The default is |
1617 | * 'plain', which is just a string with the links separated by a newline |
1618 | * character. The other possible values are either 'array' or 'list'. The |
1619 | * 'array' value will return an array of the paginated link list to offer full |
1620 | * control of display. The 'list' value will place all of the paginated links in |
1621 | * an unordered HTML list. |
1622 | * |
1623 | * The 'total' argument is the total amount of pages and is an integer. The |
1624 | * 'current' argument is the current page number and is also an integer. |
1625 | * |
1626 | * An example of the 'base' argument is "http://example.com/all_posts.php%_%" |
1627 | * and the '%_%' is required. The '%_%' will be replaced by the contents of in |
1628 | * the 'format' argument. An example for the 'format' argument is "?page=%#%" |
1629 | * and the '%#%' is also required. The '%#%' will be replaced with the page |
1630 | * number. |
1631 | * |
1632 | * You can include the previous and next links in the list by setting the |
1633 | * 'prev_next' argument to true, which it is by default. You can set the |
1634 | * previous text, by using the 'prev_text' argument. You can set the next text |
1635 | * by setting the 'next_text' argument. |
1636 | * |
1637 | * If the 'show_all' argument is set to true, then it will show all of the pages |
1638 | * instead of a short list of the pages near the current page. By default, the |
1639 | * 'show_all' is set to false and controlled by the 'end_size' and 'mid_size' |
1640 | * arguments. The 'end_size' argument is how many numbers on either the start |
1641 | * and the end list edges, by default is 1. The 'mid_size' argument is how many |
1642 | * numbers to either side of current page, but not including current page. |
1643 | * |
1644 | * It is possible to add query vars to the link by using the 'add_args' argument |
1645 | * and see {@link add_query_arg()} for more information. |
