 |
|
| Is it possible to walk to an associtive array with {section} and somehow retrieve the key name ? Because {section} has more possibilities I do not want to do it with {foreach}, but I did not find anywhere how I can show the actual keyvalue. |

no, section can only be used in conjunction with indexed arrays.
just curious: what are the "more possibilities" you have with sections?

Well, according to the documentation it's also possible to use with associative arrays, they even have an example for it (although the content of the array is shown nowhere  ), but when I want to present the data from an array in a way that I have two tables and element 1 has to be in table1, 2 in table 2, 3 again in one etc, I thought the start and the step property would be convenient. But I guess I have to split the resultset in 2 arrays then in the PHP code already. |

hiya wvdploeg.
I think that messju was only relating his response to your question: {section} doesn't handle the key portion of associative arrays. Certainly, you can iterate the contents of an associative array with {section} but it is really meant for indexed access.
I think it a little unnerving that PHP treats indexed and associative arrays as the same type, but what are you going to do? On the other hand it would be nice if there was only one catch-all loop structure in Smarty, but again... |

yes, the loop-parameter only determines the loop-count. {section loop=$array...} is merely the same a {section loop=$array|@count} or {section loop=$integer} with $integer being sizeof($array). this also works with associative arrays but is pretty meaningless since you have no way to access the array's keys or values.

this is of course a good and painless way to do it.
alternatives would be:
| Code: |
{foreach name=loop from=$table....}{if ($smarty.foreach.loop.iteration % 2) ==1)}
first table
{/if}{/foreach}
{foreach name=loop from=$table....}{if ($smarty.foreach.loop.iteration % 2) ==0)}
second table
{/if}{/foreach}
|
or assign a lookup array:
$smarty->assign('table_lookup', array_keys($table));
and use this in the section
| Code: |
{section loop=$table name=loop ...}{assign var=key value=$table_lookup[loop]}
... value: {$table.$key} ...
{/section}
|
