custom field - How to get customfield value by woocommerce product ID

admin管理员组

文章数量:1426790

I try to get the value of WooCommerce custom field from an array of product ID. No luck, I'm on the custom page not on the woocommerce loop.

tried this: $productArray1 is a list of product ID (and it's working)

global $wpdb;
global $product;

foreach ($productArray1 as $value)
{
    $querystr = "
    SELECT meta_value
    FROM $wpdb->postmeta.meta_key
    WHERE $wpdb->postmeta.meta_key = 'product_cip'
    AND $wpdb->posts.$product->ID=$value
    ORDER BY meta_value DESC
    ";

    $productsCIP = $wpdb->get_results($querystr, OBJECT);

    if ( ! $productsCIP ) {
        $wpdb->print_error();
    }
    else {
        echo $productsCIP;
    }
};

I can get all product with the same customfield like this :

$products = wc_get_products( array( 'product_cip' => '3337875548519' ) );
echo 'PRODUCT WITH SAME CIP (TOTAL : '.count($products).')<br>';

But I need to find 'product_cip' by product ID. Any clue?

Thanks for the help.

If you look for all products with same 'product_cip' value try this:

$a=array(
    'post_type'      => 'product',
    'post_status'    => 'publish',
    'posts_per_page' => - 1,
    'meta_query'     => array(
        array(
            'key'    => 'product_cip',
            'value'  => 'some value',
            'compare'=> '='
        )
    ),
    'fields' => 'ids'
);
$b=get_posts($a);
echo count($b);

if you have get all products data

$products_array=array();
foreach($b as $v){
    $_product=wc_get_product($v);
    echo $_product->get_name().',';
    $products_array[]=$_product;
}

Try this:

$product_obj=array();
foreach ($productArray1 as $value)
   {
    $product_obj['id']=$value;
    $product_obj['product_cip']=get_post_meta($value,'product_cip');
   }

or

foreach ($productArray1 as $value)
   {
    $product_obj['id']=$value;
    $product_obj['product_cip']=get_post_meta($value,'product_cip',true);
   }
echo 'PRODUCT WITH SAME CIP (TOTAL : '.count( $product_obj).')
';

if meta value not array.
