 Posted: Sat Aug 19, 2017 1:01 pm Post subject: Assign array within Smarty template |
 |
|
Hello. I have a foreach loop in my Smarty template, & everything is going OK.
however now, I want to total / count the values for each category. But, when i do my foreach for my totals, i get a blank result.
Top / first part of the code
| Code: | {foreach from=$v.data key=ka item=va}
{$ka} - {$va}<br />
{assign var=total.$ka value=$total.$ka+$va}
{/foreach}
|
Below that, I want to do a foreach on $total - however right now i'm getting a blank result. |

couldnt figure it out - to have a running total as an array. so did it in my PHP script & created a second (unnecessary) array.
Ps a single $total is ok, but not $total.item1 $total.item2 etc...
EDIT: There are hundreds of different items... i want individual totals on...
(but only a few dozen items will be shown in the totals area at a time - depending on what my script needs. i dont know the names of the totals in advance) |

The following suggestion is taken from:
https://www.smarty.net/docs/en/language.function.assign.tpl
in the Comments section.
Try:
| Code: | {assign "total" []}{* initializes to an array *}
{foreach from=$v.data key=ka item=va}
{$ka} - {$va}<br />
{$total.$ka += $va}
{/foreach} |
