 Posted: Mon Jan 05, 2004 7:06 am Post subject: section looping cuts off the last object in the array! |
 |
|
While I am doing a section loop using the following code, whatever is the last item in the $rankCats array is not ever displayed. What's wrong?
(A quick rundown: This page displays user ranks. There is an array of the rank categories ($rankCats) and one of the actual ranks($ranks).
| Code: |
{section name=RankCats loop=$rankCats start=1}
<tr>
<td colspan="2">
<div align="center" class="header">{$rankCats[RankCats].rankCatName}</div>
</td>
</tr>
{section name=ranks loop=$ranks}
{if $ranks[ranks].rankCatID == $rankCats[RankCats].rankCatID}
<tr>
<td>
{if $ranks[ranks].rankImage != ""}
<div align="center"><img src="{$ranks[ranks].rankImage}" alt="{$ranks[ranks].rankTitle}" /></div>
{/if}
</td>
<td width="100%">
{$ranks[ranks].rankTitle}
</td>
</tr>
{/if}
{/section}
{/section}
|
{$rankCats|@debug_print_var}
Generates the following output:
| Code: |
Array (5)
1 => Array (2)
rankCatName => Leaders
rankCatID => 1
2 => Array (2)
rankCatName => Team Members
rankCatID => 2
3 => Array (2)
rankCatName => Community Members
rankCatID => 3
4 => Array (2)
rankCatName => Friends
rankCatID => 4
5 => Array (2)
rankCatName => Newbies
rankCatID => 5
|
But 'Newbies' is not ever shown! |

| I don't know if I misunderstood how it was supposed to work or if this is a bug, but when you are printing from an array using "start=1" then the last item in the array is cut off. (Assuming that the array starts at index [1]. if it starts at index [0] then the first element is not shown) |

| your array is supposed to have n elements with indices from 0...(n-1) . |

Yes, I've figured this out, but I was under the impression that "start=1" would start at index 1 (which it does). It also prevents the loop from displaying the last element of the array. The solution for the problem, therefor, is to make sure that all your arrays start at index 0. It still sounds like a bug to me, given that the documentation on the start attribute is as follows
| Quote: |
The index position that the section will begin looping. If the value is negative, the start position is calculated from the end of the array. For example, if there are seven values in the loop array and start is -2, the start index is 5. Invalid values (values outside of the length of the loop array) are automatically truncated to the closest valid value. |
Nowhere in there does it refer to the elimination of array values. |

if your array indices are 0...5 (6 elements) and you set start=1 then the loop goes 1...5.
start tells smarty where the loop should start, not where the array should start. the array always starts at zero.
again: section only works if your arrays are zero-based and then nothing is cut off unexpectedly. |
