Question

我正在尝试使用来自foreach循环的名称和值填充一个空数组。我创建了一个数组$variationimages = array();，并在循环中使用$variationimages['name']和$variationimages['image']保存值。

返回$variationimages数组时，我只会得到第一项

Array
(
    [name] = Wall Profile
    [image] = <img src="example-image.jpg">
)

我想要的是它返回类似下面的内容，并能够通过使用类似$variationimages['Roof Profile']['image']的东西来访问数组中的特定项目，这将返回名称为'Roof的项目的图像。个人资料”。

 Array
    (
        [name] = Wall Profile
        [image] = <img src="example-image.jpg">
    ), 
(
            [name] = Roof Profile
            [image] = <img src="example-image.jpg">
        ),

我的代码如下：

function loop_display_variation_attribute_and_thumbnail() {
    global $product;

    // HERE your targeted product attribute taxonomy
    $taxonomy = 'pa_product_type';
    $variationimages = array();

    if( $product->is_type('variable') ) {
        foreach ( $product->get_available_variations() as $variation ) {

            if( isset($variation['attributes']['attribute_'.$taxonomy]) ) {
                // Get the "pa_product_type"
                $term_name = get_term_by('slug', $variation['attributes']['attribute_'.$taxonomy], $taxonomy)->name;
                $term_slug = get_term_by('slug', $variation['attributes']['attribute_'.$taxonomy], $taxonomy)->slug;

                $variationimages['name'] = get_term_by('slug', $variation['attributes']['attribute_'.$taxonomy], $taxonomy)->name;
                $variationimages['image'] = '<img style="display:none;" class="'.$term_slug.'-image" src="' . $variation['image']['thumb_src'] .'">';
            }
        }
        echo "<div style='display:none'>"; 
                print_r($variationimages);
                echo "</div>";
    }
}

Answer 1

Shaun，只需在此处的变量上添加其他[]：

$variationimages['name'][] = get_term_by('slug', $variation['attributes']['attribute_'.$taxonomy], $taxonomy)->name;
$variationimages['image'][] = '<img style="display:none;" class="'.$term_slug.'-image" src="' . $variation['image']['thumb_src'] .'">';

在每次迭代中，它将添加新值。

$variationimages[] = [
    'name'  => get_term_by('slug', $variation['attributes']['attribute_'.$taxonomy], $taxonomy)->name,
    'image' => '<img style="display:none;" class="'.$term_slug.'-image" src="' . $variation['image']['thumb_src'] .'">'
];

我认为您必须用对象或数组填充

like，您必须创建类，例如Item $one_item= new Item();

并编写如下代码：

function loop_display_variation_attribute_and_thumbnail() {
    global $product;

    // HERE your targeted product attribute taxonomy
    $taxonomy = 'pa_product_type';
    $variationimages = array();

    if( $product->is_type('variable') ) {
        foreach ( $product->get_available_variations() as $variation ) {

            if( isset($variation['attributes']['attribute_'.$taxonomy]) ) {
                // Get the "pa_product_type"
                $term_name = get_term_by('slug', $variation['attributes']['attribute_'.$taxonomy], $taxonomy)->name;
                $term_slug = get_term_by('slug', $variation['attributes']['attribute_'.$taxonomy], $taxonomy)->slug;
$one_item=New Item ();

                $one_item=>name = get_term_by('slug', $variation['attributes']['attribute_'.$taxonomy], $taxonomy)->name;
                $one_item=>image = '<img style="display:none;" class="'.$term_slug.'-image" src="' . $variation['image']['thumb_src'] .'">';
array_push($variationimages,$one_item);

            }
        }
        echo "<div style='display:none'>"; 
                print_r($variationimages);
                echo "</div>";
    }
}

遍历foreach语句并添加到空的多维数组中
