问题描述
我有动态的项目数量,需要将其分为几列.假设我得到了这个:
I have a dynamic number of items in which I'll need to divide into columns. Let's say I'm given this:
array("one", "two", "three", "four", "five", "six", "seven", "eight")
我需要生成这个:
<ul>
<li>one</li>
<li>two</li>
<li>three</li>
<li>four</li>
</ul>
<ul>
<li>five</li>
<li>six</li>
<li>seven</li>
<li>eight</li>
</ul>
以下是一些规则:
- 如果没有任何物品,我不想吐出任何东西
- 如果有16个或16个以下的项目,则每个
<ul>
的ID如4个项目
- 如果有16个以上的项目,我希望将其均匀分布
- 我将不得不按字母顺序对商品进行重新排序.如果有17个项目,则第17个项目需要转到第一列,但所有内容都需要重新排序.
- if there are no items, I don't want anything to be spat out
- if there are 16 or under 16 items, id like 4 items per
<ul>
- if there are more than 16 items, i'd like it to be spread out evenly
- i'll have to alphabetically reorder items. if there are 17 items, the 17th item will need to go to the first column but everything needs to be reordered.
到目前为止我所拥有的:
What I have so far:
function divide( $by, $array ) {
14 $total = count( $array );
15 $return = array();
16 $index=0;
17 $remainder = $total % $by !== 0;
18 $perRow = $remainder ?
19 $total / $by + 1:
20 $total / $by
21 ;
22
23 for ( $j = 0; $j<$by; $j++ ) {
24 //$return[] = array();
25
26 if ( $index == 0 ) {
27 $slice = array_slice( $array, 0, $perRow );
28 $index = $perRow;
29 $return[$j] = $slice;
30 } else {
31 $slice = array_slice( $array, $index, $perRow );
32 $index = $index+$perRow;
33 $return[$j] = $slice;
34 }
35 }
}
我输入一个数字,例如divide(4,$ arrRef),该数字决定了列数,但是我需要重构以便确定列数
I feed a number, like divide( 4, $arrRef ), the number dictates the # of columns, but I need to refactor so it determines the number of columns
推荐答案
我在视图模板中使用了此代码.
I used this code inside my view template..
<?php
$col = 3;
$projects = array_chunk($projects, ceil(count($projects) / $col));
foreach ($projects as $i => $project_chunk)
{
echo "<ul class='pcol{$i+1}'>";
foreach ($project_chunk as $project)
{
echo "<li>{$project->name}</li>";
};
echo "</ul>";
}; ?>
