 Posted: Thu Nov 13, 2003 9:34 pm Post subject: can't print both key and value of associative array |
 |
|
I think that this is probably simple,. but I can't figure out how to output both the key and value of an array. Basically, I have an associative array that is dynamically generated, and I want to pass the array into smarty section and print the values and the keys.
My PHP CODE:
| Code: |
foreach($_POST as $formitem => $value) {
$strata_val[$formitem] = $value;
}
$smarty->assign('strata_val',$strata_val);
|
And my Smarty Code:
| Code: |
{section name=stratum loop=$strata_val}
<input type="hidden" name={$strata_val[stratum]} value={stratum} />
{/section}
|
Which should result in a bunch of hidden variables with the value being the key and the name being the value of the associative array $strata_val. Obvioulsy, that is not happening, and I cannot for the life of me figure out why.
Any Help is appreciated.
Thanks a lot.[/code] |

| use {foreach} instead of section, maybe. |

yeah, i just saw that in a different thread... asked too soon  . Now I can get the value, but can't get the key to print. I think that I am copying this straight from the manual too (page34).
| Code: |
{foreach name=stratum item=strat_val from=$strata_val}
{foreach key=key item=item from=$strat_val}
<input type="hidden" name={$key} value={$item} />
{/foreach}
{/foreach}
|
which results in:
| Code: |
<input type="hidden" name=0 value=213131 />
<input type="hidden" name=0 value=534452 />
<input type="hidden" name=0 value=24566634 />
<input type="hidden" name=0 value=524242 />
<input type="hidden" name=0 value=5534567645 />
<input type="hidden" name=0 value=4242423 />
|
so the name field is obviously wrong.
Ideas? |

| maybe read the manual a little closer and use the "key"-attribute of {foreach}. |
