Hi All,

I have an array of objects.
I need to iterate through in reverse.

This doesn't work.
The test to display the index works fine but my referencing of the document doesn't show up anything . I would expect it to print Object.
Code:

{section name=document loop=$navDocsArray  step=-1}
   {$smarty.section.document.index}
   {$navDocsArray[$smarty.section.document.index]}
{/section}


Anyone see how I am being dumb?

Thanks,

TW

Your array is 0-based and indexed sequential? And why not just use {$navDocsArray[document]} ?

Hi Boots,

Think I tried that and it didn't work either but if that should work then I guess I need to check out what else might be going wrong at least I know what should work.

Thanks,

Paul

Smarty doesn't do var-vars. Use an array instead.

{$apple[x][i].name}

Or pack your apple vars into an array. Then use dynamic keys:

{assign var=apple value="apple_`$smarty.section.x.iteration`}
{$pack[$apple][i].name}

[also, maybe look up the special $smarty var in the manual and re-read the {section} docs]

And what the hell is wrong with foreach? The who idea of templates is to separate display concerns from other application concerns. As a consequence, you typically simplify the data you send to the template so as to make it easier to use and access. If you take a moment to create some less obtuse arrays to work with, you won't spend so much struggling in your templates or writing ugly template code.

Best.

I never told you to do it that way. I suggested:

Code:
$apples = array();
...
$apples[$x] = ${"apple_$x"}; // or whatever
$smarty->assign('apples, $apples);
...
{$apples[x][i].info}


Like I said: the more you fight against the way Smarty actually does work, the more problems you will have.

Who said to assign $apples in a loop? Build your array then assign it. Otherwise use append(). And please stop with the funky formatting. It hurts my eyes and it makes just ignore the message. In fact, I didn't even read past the first 3 lines.

...and please try to avoid things like eval....it seems like all the things you are trying are making your work harder than it needs be.
