smarty中的动态变量数组名称

Question

i am wondering about how to implement a dynamic increment variable, this is my php

<?php 

$sections =5;

for($g=1; $g<=$sections; $g++){
$smarty->assign(array(
        'products-'.$g => $dbvariable,
        'add_display-'.$g => $othervar ));
}

$smarty->assign('number', $sections);
?>

this is my smarty template

{assign var=cnt value=1}
{while $cnt <= $number}
{foreach from=$products-`.$cnt` item=prod name=mysection}
<div class="section-{$cnt}">
// my output here
 <h3>{$products-`$cnt`.name}</h3>
  <img src="{$add_display-`$cnt`.src}">
</div>
{/foreach}
{assign var=cnt value=$cnt+1}
{/while}

can anyone guide me on how to implement the increment dynamic variable on smarty?

it seems like I'm lost here

I'm not sure if there is a reason for the approach you've started down, but this will be easier to read as an answer than a comment.

Rather than dynamic variable names, why not just use arrays? This should be equivalent to what you want, I think:

<?php 

$sections =5;

$products = array();
$add_display = array();
for($g=1; $g<=$sections; $g++){
    $products[$g] = $dbvariable;
    $add_display[$g] = $othervar;
}

$smarty->assign('products', $products);
$smarty->assign('add_display', $add_display);
$smarty->assign('number', $sections);

And then (this could probably be simplified further, but I've left it as similar to yours as possible so you can see what I've changed):

{assign var=cnt value=1}
{while $cnt <= $number}
    {foreach from=$products[$cnt] item=prod name=mysection}
    <div class="section-{$cnt}">
        // my output here
        <h3>{$prod.name}</h3>
        <img src="{$add_display[$cnt].src}">
    </div>
    {/foreach}
{assign var=cnt value=$cnt+1}
{/while}

Incidentally, that <h3> didn't look quite right, so I've guessed at what it should have been.
