Hi everybody,
As you may notice, I'm a Smarty newbie  . I managed to get a {foreach from=$result_array item=$row} with $result_array build from a mysql query fetched array. Now, I'm facing a new challenge:
How can I use {foreach} with $result_array being a array with variable number of columns?
Q: Why I need this?
A: I want to create an html table with a variable number of columns, so, some times this $result_array will have 4, 5, 6 or 8 columns, doesn't matter.
Now I'm using {foreach from=$result_array item=$row} and when I need to access some data I use {$row.fieldname}. But with a variable number of fields, I don't know the names of those field. Is threre any way to access this data?
Thanks in advance,
Canoramix |

sure. use two nested foreachs:
| Code: | {foreach from=$result_array item=row}
<tr>
{foreach from=$row key=name item=cell}
<td>{$row.$name} is the same as {$cell}</td>
{/foreach}
</tr>
{/foreach}

Thanks Messju, it worked.
BTW, I tried to use {section} instead of {foreach} and the code is:
| Code: | {section loop=$result_array name=row}
<tr>
{section loop=$result_array[row] name=cell}
<td>{$result_array[row][cell]}</td>
{/section}
</tr>
{/section}
