 Posted: Sun Apr 20, 2003 5:01 pm Post subject: Block-function {counter} |
 |
|
I would like to be able to easily make page numbers in any format. I couldn't find any function in the docs for doing this, so I am requesting it here.
This is an example of what I mean:
{counter from=1 to=$pagenumber item=number}
<a href="mypage.php?p={$number}">{$number}</a>
{/counter}

Hi.
Yep, no generic loops in Smarty.
Is it possible that you can assign this from PHP as an array so that you can use {foreach} or {section}?
test.php
| Code: | <?php
$smarty=new Smarty;
$counter=array();
for ($i=1; $i<= 10; $counter[] = $i++);
$smarty->assign('pages', $counter);
$smarty->display('test.tpl');
?> |
test.tpl
| Code: | {section name=number loop=$pages}
<a href="mypage.php?p={$pages[number]}">{$number}</a>
{/section} |
Yes, creating a list like this to iterate over is inefficient for large lists, but look how the details of the looping are taken out of the template code--a real plus when you have different people doing template design/building and application design/building. |

| I realized that before posting. As you said, however, this is very inefficient. What you stated is what I am currently using as a temporary solution. Thanks for the reply, though! |

|

I just read messju's interesting post on the smarty-dev mailing list concerning the addition of the $repeat parameter. Clever indeed, as it gives blocks the ability to maintain internal loop counters.
Here is a simple plugin to implement your counter. I haven't benched the performance of the interface, but hey, it works!
This requires the CVS version of Smarty.
block.loop.php
| Code: | <?php
/**
* Smarty plugin
* @package Smarty
* @subpackage plugins
*/
/**
* Smarty loop block plugin
*
* Type: loop function<br>
* Name: loop<br>
* Purpose: generic looping block
*/
function smarty_block_loop($params, $content, &$this, &$repeat)
{
// accept only 'name', 'from', 'to' and 'item' as params
$name = $params['name'];
$from = $params['from'];
$to = $params['to'];
$item = $params['item'];
if ($this->block_loop[$name]['looping'] == True)
{
$current = $this->block_loop[$name]['current'];
}
else
{
$this->block_loop[$name]['looping'] = True;
$this->block_loop[$name]['from'] = $from;
$this->block_loop[$name]['to'] = $to;
$this->block_loop[$name]['item'] = $item;
$this->block_loop[$name]['current'] = $from;
$current = --$from;
}
$current++;
$this->assign($item, $current);
$this->block_loop[$name]['current'] = $current;
$repeat = ($current <= $to) ? True : False;
$this->block_loop[$name]['looping'] = ($current <= $to) ? True : False;
return $content;
}
?> |
sample.tpl
| Code: | {loop name=test from=1 to=10 item=number}
<a href="mypage.php?p={$number}">{$number}</a>
{/loop} |
Please, don't even think of using this code for production. It WILL break and except for demonstrating the purpose, it is just a quick hack. I hope it gets the ball rolling for you.
Good luck and Caveat Emptor! |

well that's much simpler  Would you believe it never occured to me to try to use section like that? I'm to stuck on foreach I guess 
To think messju is suggesting {section}  |

Hi,
very helpful topic and it was luck that i stumbled over it. I think it's very unclear in the Documentation. It would help a lot if it would be mentioned somewhere in the docs that you can use an integer for the attribute loop. |
