|
1948 * create the paginated links. The 'format' argument is then used for replacing |
|
1949 * the page number. It is however, most likely and by default, to be used on the |
|
1950 * archive post pages. |
|
1951 * |
|
1952 * The 'type' argument controls format of the returned value. The default is |
|
1953 * 'plain', which is just a string with the links separated by a newline |
|
1954 * character. The other possible values are either 'array' or 'list'. The |
|
1955 * 'array' value will return an array of the paginated link list to offer full |
|
1956 * control of display. The 'list' value will place all of the paginated links in |
|
1957 * an unordered HTML list. |
|
1958 * |
|
1959 * The 'total' argument is the total amount of pages and is an integer. The |
|
1960 * 'current' argument is the current page number and is also an integer. |
|
1961 * |
|
1962 * An example of the 'base' argument is "http://example.com/all_posts.php%_%" |
|
1963 * and the '%_%' is required. The '%_%' will be replaced by the contents of in |
|
1964 * the 'format' argument. An example for the 'format' argument is "?page=%#%" |
|
1965 * and the '%#%' is also required. The '%#%' will be replaced with the page |
|
1966 * number. |
|
1967 * |
|
1968 * You can include the previous and next links in the list by setting the |
|
1969 * 'prev_next' argument to true, which it is by default. You can set the |
|
1970 * previous text, by using the 'prev_text' argument. You can set the next text |
|
1971 * by setting the 'next_text' argument. |
|
1972 * |
|
1973 * If the 'show_all' argument is set to true, then it will show all of the pages |
|
1974 * instead of a short list of the pages near the current page. By default, the |
|
1975 * 'show_all' is set to false and controlled by the 'end_size' and 'mid_size' |
|
1976 * arguments. The 'end_size' argument is how many numbers on either the start |
|
1977 * and the end list edges, by default is 1. The 'mid_size' argument is how many |
|
1978 * numbers to either side of current page, but not including current page. |
