smarty question

[elduderino]

Hi,

Im creating some pagination with smarty...ive got the page numbers spitting out fine.....like so:

 //If there are no results then print a message saying so
      if(mysql_num_rows($query) == 0){
        $tpl->assign("noresults", "1");
      }
 
 
      //If we are not on page 1 then output a previous link
      if($page != 1) {
        $pageprev = $page - '1';
        $tpl->assign('prev','1');
        $tpl->assign('cat', $category);
        $tpl->assign("pageprev", $pageprev);
        $tpl->assign("limit", $limit);
      }
 
      //print a next button if there are enough results
      //there wouldnt be if there were ten rows, the limit was 2 and we were on page 2
      // 10 - (2 x 5) = 0
      if(($totalrows - ($limit * $page)) > 0) {
         $pagenext = $page + '1';
         $tpl->assign('next','1');
        $tpl->assign('cat', $category);
        $tpl->assign("pagenext", $pagenext);
        $tpl->assign("limit", $limit);
      }
 
 
     //Now build the page numbers
 
     $numofpages = ceil($totalrows / $limit);
 
 
     for($i = 1; $i <= $numofpages; $i++) {
        $pagingArray = array();
        $pagingArray['pageNo'] = $i;
        $pagingArray['cat'] = $category;
        $tpl->append("pagingArray", $pagingArray);
        if($i == $page) {
        $tpl->assign("current", '1');   
        }

and the assocaited template code :

<ul class="paging">
{if $prev}
<li><a href="results.php?category={$cat}&page={$pageprev}">Previous</a></li>
{/if}
{foreach from=$pagingArray item=i}
{if $current}
<li>{$i.page}</li>
{/if}   
<li><a href="results.php?category={$i.cat}&page={$i.pageNo}">{$i.pageNo}</a></li>
{/foreach}
{if $next}
<li><a href="results.php?category={$cat}&page={$pagenext}">Next</a></li>
{/if}
 
</ul>

Now, this all works dandy but the rpoblem comes when i want to diplsay just the page number and not a link for when im on the corresponsing page.....so if im on page 2 i dont want the 2 to be a link in the page number list...i just want it to be static....

Ive had a stab at it....the php code correct ( its the if $page = $i bit above)
but i dont know how to get it outputting in the template ( ive also tried to put it in the template but it doesnt work....how do i do this????/

I would modify your code as such

 //If there are no results then print a message saying so
      if(mysql_num_rows($query) == 0){
        $tpl->assign("noresults", "1");
      }
 
 
      //If we are not on page 1 then output a previous link
      if($page != 1) {
        $pageprev = $page - '1';
        $tpl->assign('prev','1');
        $tpl->assign('cat', $category);
        $tpl->assign("pageprev", $pageprev);
        $tpl->assign("limit", $limit);
      }
 
      //print a next button if there are enough results
      //there wouldnt be if there were ten rows, the limit was 2 and we were on page 2
      // 10 - (2 x 5) = 0
      if(($totalrows - ($limit * $page)) > 0) {
         $pagenext = $page + '1';
         $tpl->assign('next','1');
        $tpl->assign('cat', $category);
        $tpl->assign("pagenext", $pagenext);
        $tpl->assign("limit", $limit);
      }
 
 
     //Now build the page numbers
 
     $numofpages = ceil($totalrows / $limit);
 
 
     for($i = 1; $i <= $numofpages; $i++) {
        $pagingArray = array();
        $pagingArray['pageNo'] = $i;
        $pagingArray['cat'] = $category;
        $pagingArray['current'] = $i == $page;
        $tpl->append("pagingArray", $pagingArray);
 
     }

<ul class="paging">
{if $prev}
<li><a href="results.php?category={$cat}&page={$pageprev}">Previous</a></li>
{/if}
{foreach from=$pagingArray item=i}
{if $i.current}
<li>{$i.pageNo}</li>
{else}   
<li><a href="results.php?category={$i.cat}&page={$i.pageNo}">{$i.pageNo}</a></li>
{/if}
{/foreach}
{if $next}
<li><a href="results.php?category={$cat}&page={$pagenext}">Next</a></li>
{/if}
 
</ul>

ah santouras thankyou! I didnt know you could if and elses in a for each loop....im new to smarty...

Thanks again

[santouras]

no problems. Have a read through of the smarty manual, you can do some really cool stuff with foreach and especially section loops. I use them for paging all the time. Something like this

{section name=paging loop=100 step=10}
<a href="/search/start/{$smarty.section.paging.index}">{$smarty.section.paging.iteration}</a>
{/section} 

But of course with statements to check for the current page and the like
