Question

我试图在Zurb的Foundation 4中进行一些源代码排序，问题在于我的PHP逻辑。我目前正在开发CMS，开发人员可以做的是编辑列数和列的宽度（跨度），所以假设他创建了3列，下一个跨度= 1,3和8 ：

Array
(
    [0] => stdClass Object
        (
            [span] => 1
            [position] => 0
        )

    [1] => stdClass Object
        (
            [span] => 3
            [position] => 1
        )

    [2] => stdClass Object
       (
           [span] => 8
           [position] => 2
       )

)

渲染的标记为：

<div class="column small-1"></div>
<div class="column small-3"></div>
<div class="column small-8"></div>

所以在这种情况下，主要内容将位于较大的列中，因此我所做的是使用PHP对它们进行重新排序，以便它们从大到小排序（以便主要内容首先显示）：

Array
(
    [0] => stdClass Object
        (
            [span] => 8
            [position] => 2
        )

    [1] => stdClass Object
        (
            [span] => 3
            [position] => 1
        )

    [2] => stdClass Object
       (
            [span] => 1
            [position] => 0
       )

)

渲染的标记为：

<div class="column small-8"></div>
<div class="column small-3"></div>
<div class="column small-1"></div>

我需要知道的是如何自动添加相应的推/拉类以获得结果：

Array
(
    [0] => stdClass Object
        (
            [span] => 8
            [position] => 2
            [push] => 4
            [pull] => 0
        )

    [1] => stdClass Object
        (
            [span] => 3
            [position] => 1
            [push] => 0
            [pull] => 7
        )

    [2] => stdClass Object
       (
            [span] => 1
            [position] => 0
            [push] => 0
            [pull] => 11
       )

)

结果标记应为：

<div class="column small-8 push-4"></div>
<div class="column small-3 pull-7"></div>
<div class="column small-1 pull-11"></div>

我已经制作了一个能够做到这一点的功能，但它没有给我正确的解决方案，而且我觉得它太复杂了：

/**
 * Reorders the columns so that they are exactly like the design's order, because we  are ordering the columns from largest to smallest
 * hoping that the largest means more important content than the smallest, so we need a way to return to the original order
 * @param $columns - The column array
 * @param $col - the current column
 * @param $key - current column key
 * @return array
 */
private function source_ordering($columns, $col, $key)
{

    $ordering = array();
    $ordering['pull'] = 0;
    $ordering['push'] = 0;
    $total_spans = 0;

    //How many positions to loop back/forth in the array
    $position_key = $col->position - $key;

    print_r('-------');

    //Push column
    if ($col->position > $key) {

        //Loop forth in the array and add all the column "spans"
        $i = 1;
        while ($i <= $position_key) {
            $total_spans += $columns[$key + $i]->span;
            $i++;
        }

        $ordering['push'] = $col->push = $total_spans;

    }

    //Position hasn't changed - Pull?
    else if ($position_key === 0) {

        var_dump($key);

        $pos = $key - 1;
        while ($pos >= 0) {

            print_r($columns[$pos]);

            //Is the previous column pushed or pulled?
            if ($columns[$pos]->push) {
                $ordering['pull'] -= $columns[$pos]->span;
            } else {
                $ordering['pull'] += $columns[$pos]->span;
            }

            $ordering['pull'] = abs($ordering['pull']);

            $pos--;
        }

    }

    //Pull column
    else {

        //Make it positive (easier to calculate)
        $position_key = abs($position_key);

        //Loop forth in the array and add all the column "spans"
        $i = 1;
        while ($i <= $position_key) {
            $total_spans += $columns[$key - $i]->span;
            $i++;
        }

        $ordering['pull'] = $col->pull = $total_spans;

    }

    return $ordering;

}

在每个列数组上调用此函数：

foreach ($columns as $col_key => $col)
{
    $ordering = $this->source_ordering($columns, $col, $col_key);
    $col->pull = $ordering['pull'];
    $col->push = $ordering['push'];
}

请记住，开发人员可以创建1,2,3或更多列，而不仅仅是我发布的示例。

我怎样才能做到这一点？
