在Woocommerce购物车中显示自定义字段的值结帐项目 [英] Display Custom Field's Value in Woocommerce Cart & Checkout items
问题描述
一段时间以来,我一直在寻找一种解决方案,但是找不到合适的解决方案。我在产品页面中使用了几个自定义字段,例如最短烹饪时间,食物可获取性等。因此,我想在购物车和结帐页面中显示此自定义字段的值。
I have been looking for a solution for a while all over internet but couldn't find any proper solution. I am using several custom fields in my product page like, 'Minimum-Cooking-Time', 'Food-Availability' etc. So, I like to show this custom field's value in my cart and checkout page.
我尝试了功能文件中的代码片段,还编辑了woocommerce购物车文件。我尝试了一些代码,但是它们没有从我的自定义字段中提取任何数据。
I tried snippets in function file and editing woocommerce cart file too. I have tried several codes but they are not pulling any data from my custom fields.
如下面的屏幕快照所示,我想在每个产品的黑色矩形区域中显示最小烹饪时间:
As you can see in the screenshot below, I want to show 'Minimum-Cooking-Time' in that black rectangular area for every product:
我使用了以下代码:
add_filter( 'woocommerce_get_item_data', 'wc_add_cooking_to_cart', 10, 2 );
function wc_add_cooking_to_cart( $other_data, $cart_item ) {
$post_data = get_post( $cart_item['product_id'] );
echo '<br>';
$Add = 'Cook Time: ';
echo $test;
$GetCookTime = get_post_meta( $post->ID, 'minimum-cooking-time', true );
$GetCookTime = array_filter( array_map( function( $a ) {return $a[0];}, $GetCookTime ) );
echo $Add;
print_r( $GetCookTime );
return $other_data;
}
但这显示标签 Cook Time,但不显示
But, this shows the label 'Cook Time' but not showing any value beside it.
任何帮助将不胜感激。
谢谢。
推荐答案
您的问题出在 get_post_meta()
函数,最后一个参数设置为 true
,因此您将获得自定义字段值作为字符串。
然后您正在使用 array_map()
PHP函数,它正在期望数组 >,但不是字符串值。
Your problem is in get_post_meta()
function which last argument is set to true
, so you get a custom field value as a string.
Then you are using just after the array_map()
PHP function that is expecting an array but NOT a string value.
我认为您不需要使用
array_map()
用作get_post_meta()
函数的最后一个参数设置为true
一个字符串而不是一个非序列化的数组。
I think you don't need to use
array_map()
function asget_post_meta()
function with last argument set totrue
will output a string and not an unserialized array.
还可以设置您正在使用的 $ product_id
在 get_post_meta()
Also you can set the $product_id
that you are using in get_post_meta()
function as first argument, in a much simple way.
因此,您的代码应以这种方式工作:
So your code should work, this way:
// Render the custom product field in cart and checkout
add_filter( 'woocommerce_get_item_data', 'wc_add_cooking_to_cart', 10, 2 );
function wc_add_cooking_to_cart( $cart_data, $cart_item )
{
$custom_items = array();
if( !empty( $cart_data ) )
$custom_items = $cart_data;
// Get the product ID
$product_id = $cart_item['product_id'];
if( $custom_field_value = get_post_meta( $product_id, 'minimum-cooking-time', true ) )
$custom_items[] = array(
'name' => __( 'Cook Time', 'woocommerce' ),
'value' => $custom_field_value,
'display' => $custom_field_value,
);
return $custom_items;
}
代码位于您的活动子主题(或主题)的function.php文件中,或者
此代码具有完整的功能并经过测试。
