使用Woocommerce中的wc_get_products查询所有没有API的产品

Question

In Woocommerce I am trying to get all products using wc_get_products() as follow:

$args = array( 'status' => 'publish' );
$products = wc_get_products( $args );
return $products;

But it return an empty string.

How can I get all products using wc_get_products()? What I am doing wrong?

Answer 1

Your code works and will give you an array of the 10 last created WC_Product objects. So when you return this array of WC_Product objects, it gives nothing as it's not a string.

If you want to get all products you need to add 'limit' argument with a value of -1 like:

// An array of all published WC_Product Objects
$products = wc_get_products( array( 'status' => 'publish', 'limit' => -1 ) );

// Displaying the number of products in this array
echo '<p>Number of products: ' . sizeof( $products ) . '</p>';

// Loop through products and display some data using WC_Product methods
foreach ( $products as $product ){
    echo '<p>';
    echo 'Type: '  . $product->get_type() . '<br>';  // Product type
    echo 'ID: '    . $product->get_id() . '<br>';    // Product ID
    echo 'Title: ' . $product->get_title() . '<br>'; // Product title
    echo 'Price: ' . $product->get_price();          // Product price
    echo '</p>';
}

Example - The following code will output in a string a coma separated suite of all your product IDs:

echo '<p>Products IDs list: ' . implode( ', ', wc_get_products( array( 'status' => 'publish', 'limit' => -1, 'return' => 'ids' ) ) ) . '</p>';

Tested and works.
