As is said in SmartyPaginate doc,
Code:
SmartyPaginate:setUrl() set the URL  used in the paginator links to navigate from page.

so if I want to setting custom parameters in SmartyPaginate,first I have retain it in some session variable,every time I invoke smartypaginate I have to setup the parameters and pass it to smarty using setUrl(),and I have aslo have to watch if the parameter changes I have to reset paginator.I find it a hardwork if I have many parameter to pass.

I changed SmartyValidate.class.php to suit my needs ,It works but I don't know whether it's right.

Code:


    function _getNextPageItem($id = 'default') {
               
        $_next_item = $_SESSION['SmartyPaginate'][$id]['current_item'] + $_SESSION['SmartyPaginate'][$id]['item_limit'];
       
        return ($_next_item <= $_SESSION['SmartyPaginate'][$id]['item_total']) ? $_next_item : false;
    }   
   
    /**
      * set custom url parameters
      *
      * @param string $id the pagination id
      */
    function setParam($params,$id = 'default'){

       if(!isset( $_SESSION['SmartyPaginate'][$id]['param']) ||  $_SESSION['SmartyPaginate'][$id]['param']!=$params){
          SmartyPaginate::reset($id);//reset the paginator in case the parameter changes
       }
       $_SESSION['SmartyPaginate'][$id]['param'] = &$params;
    }

    /**
      * get custom url parameters
      *
      * @param string $id the pagination id
      */
    function getParam($id = 'default'){
       foreach( $_SESSION['SmartyPaginate'][$id]['param'] as $key => $param){
          $params .= $key.'='.$param.'&' ;   
       }
       return $params;
    } 



and in function.paginate_middle.php I changed it as follows:
Code:

 if($_item != $_curr_item) {
            $_this_url = $_url;
            $_this_url .= (strpos($_url, '?') === false) ? '?' : '&';
            $_this_url .= SmartyPaginate::getParam($_id);
            $_this_url .= SmartyPaginate::getUrlVar($_id) . '=' . $_item;
            $_ret .= '<a href="' . str_replace('&', '&', $_this_url) . '">'
. $_text . '</a>';
        }



and I used it like this:


Code:

$params = array();

if(isset($_GET['subjectId']) && is_numeric($_GET['subjectId'])){
   $subjectId =  $_GET['subjectId'];
   $params['subjectId'] = &$subjectId;
 }else{
   $subjectId=-1;
 }

if(isset($_GET['sourceId']) && is_numeric($_GET['sourceId'])){
   $sourceId =  $_GET['sourceId'];
   $params['sourceId'] = &$sourceId;
 }else{
   $sourceId=-1;
 }


SmartyPaginate::connect('myasklist');

SmartyPaginate::setLimit(10,'myasklist');
SmartyPaginate::setParam($params,'myasklist');



finally I will get url like:

/my/qna/newsolvelist/?subjectId=4&sourceId=2&next=51

I haven't test it as to code performance.

any suggestions?

So it looks like you want the ability to add parameters to the pagination URL, but those parameters are only good for the current invocation? Or they persist?
