I write the following code to display articles list with pages. Pls. tell if there some thing wrong or will cause errors with the whole phpwcms system!
Code: Select all
//In file \include\inc_front\content.func.inc.php add the following
// usage: ARTICLELIST:max_count (display max_count summaries from CatAlias)
$content["all"] = preg_replace('/\{ARTICLELIST:(\d+)\}/ie', 'get_summary_list ($content["cat_id"], $template_default, $1, $db);', $content["all"]); Code: Select all
//Add the following into the file \include\inc_front\front.func.inc.php.
//The level 1 link to each cat must be in this format: http://www.yourweb.com/index.php?[color=blue]cat_alias[/color]&page=0&sum=0
function get_pager_data($total, $limit, $page) {

$offset = ($page - 1) * $limit;
$ret = array ("offset" => $offset, "limit" => $limit, "numPages" => $numPages, "page" => $page);
return (sizeof($ret)) ? $ret: array();
}
function get_data_from_acat($cat_id, $offset, $limit, $dbcon) {
//This code block is similar to the get_actcat_articles_data function, so you can modify the function instead
