Smarty: Outputting Rows Based on # of Items in Array
I am using Smarty to output an array to an HTML table. I want each row of the table to 开发者_开发知识库have no more than 8 items in it. If the array has more than 8 items then the code would make a new row for the overflowing items.
How can I do this? Is this clear?
It's been a long time since I've used Smarty, but you should be able to do this like this:
<tr>
{foreach from=$items key=myId item=i name=foo}
{if $smarty.foreach.foo.index % 8 == 0 && $smarty.foreach.foo.index > 0 }
</tr><tr>
{/if}
<td>{$i.label}</td>
{/foreach}
</tr>
The modulus operator only returns 0 if the index is dividable by 8, So before every 9th item it adds a new row. We don't want this for the first item to happend so let's check that as well.
Here's how I did it in the past:
<table>
{foreach from=$array item='array_item' name='array_items'}
{if $smarty.foreach.array_items.first}
{* first item - start of all the rows *}
<tr><td>{$array_item}</td>
{elseif $smarty.foreach.array_items.index % 8 == 0}
{* 8 items added to row - start new row *}
</tr><tr><td>{$array_item}</td>
{elseif $smarty.foreach.array_items.last}
{* last item - end the row (or add logic to fill out row with empty cells if needed) *}
<td>{$array_item}</td></tr>
{else}
{* normal item - add cell *}
<td>{$array_item}</td>
{/if}
{/foreach}
</table>
