订单号

Question

我在那里我收集的数据，然后爆炸的功能，这个功能是同时的内部，wordpress的

global $woocommerce; 
global $wpdb; 
$args = array('post_type' => 'product', 'stock' => 1, 'posts_per_page' => -1); 
$loop = new WP_Query($args); 
while ($loop->have_posts()) : $loop->the_post();   
$order_id = $loop->post->ID; 
foreach($product as $sku){ 
    $sku = $product->get_sku(); 
    $sku_s = explode('-', $sku); 
    $camp = $sku_s[0]; 
    $itm_n = $sku_s[1]; 
} 

<h6><span class="a1"><?php echo $camp;?></span>-<span class="a2"><?php echo $itm_n;?></span></h6> 

我的输出
是这样

<h6><span class="a1">581</span>-<span class="a2">20</span></h6> 
<h6><span class="a1">581</span>-<span class="a2">50</span></h6> 
<h6><span class="a1">581</span>-<span class="a2">1</span></h6> 
<h6><span class="a1">581</span>-<span class="a2">6</span></h6> 
<h6><span class="a1">581</span>-<span class="a2">9</span></h6> 

581-20
581-1
581-9 ....等..

，但我需要的奥德分类编号，例如

581-1
581-6
581-9 ....等等...

感谢您帮助。

Answer 1

创建一个比较功能为您的SKU即

function myComparison(a,b) { 
    a.id<b.id; 
} 

然后使用一个标准的数组排序

$skus.sort(myComparison); 

不能清楚地看到你的对象是如何布局，但我希望这有助于引导你顶部正确的答案。

首先，这个foreach循环没有多大意义。你为什么要迭代$sku立即用$product->get_sku()覆盖它？

//what you wrote 
foreach($product as $sku){ 
    $sku = $product->get_sku(); 
    $sku_s = explode('-', $sku); 
    $camp = $sku_s[0]; 
    $itm_n = $sku_s[1]; 
} 

//did you mean this? 
foreach($products as $product){ 
    $sku = $product->get_sku(); 
    $sku_s = explode('-', $sku); 
    $camp = $sku_s[0]; 
    $itm_n = $sku_s[1]; 
} 

假设可以识别在每次迭代中被提取哪个变量（和它类似于上面的校正回路）可以尝试两件事情之一。

（1）您是否试过将orderby传递给您正在运行的WP_Query？ http://codex.wordpress.org/Class_Reference/WP_Query#Order_.26_Orderby_Parameters

（2）您需要重新为您的结果编制索引，以便您的订单基于SKU的自然排序顺序。

while ($loop->have_posts()) : $loop->the_post(); 
    $order_id = $loop->post->ID; 

    //create a new array to hold by SKU 
    $sortProducts = array(); 

    foreach($products as $product){ 
     $sortProducts[$product->get_sku()] = $product; 
    } 

endwhile; 

//sort natural order 
ksort($sortProducts, SORT_NATURAL); 

//notice that this is a different foreach loop here 
foreach($sortProducts as $sku => $product){ 
    $sku = $product->get_sku(); 
    $sku_s = explode('-', $sku); 
    $camp = $sku_s[0]; 
    $itm_n = $sku_s[1]; 
    echo "<h6><span class=\"a1\">$camp</span>-<span class=\"a2\">$itm_n</span></h6>"; 
}
