我想讓用戶在一個表單中選擇產(chǎn)品。為此，我需要使用已發(fā)布的 WooCommerce 產(chǎn)品動態(tài)填充表單。我找到了一個用 WooCommerce 產(chǎn)品填充選擇字段的解決方案。但是用戶應該能夠選擇每種產(chǎn)品的數(shù)量。因此我需要使用列表字段并填充列表字段的單元格。以下是列表字段的外觀：SKU 和標題字段應動態(tài)填充。數(shù)量字段供用戶填寫。這是我使用 WooCommerce 產(chǎn)品數(shù)據(jù)填充選擇字段的代碼：add_filter( 'gform_pre_render_5', 'populate_posts' );add_filter( 'gform_pre_validation_5', 'populate_posts' );add_filter( 'gform_pre_submission_filter_5', 'populate_posts' );add_filter( 'gform_admin_pre_render_5', 'populate_posts' );function populate_posts( $form ) { foreach ( $form['fields'] as &$field ) { if ( $field->type != 'select' || strpos( $field->cssClass, 'populate-posts' ) === false ) { continue; } // you can add additional parameters here to alter the posts that are retrieved // more info: http://codex.wordpress.org/Template_Tags/get_posts $posts = get_posts( 'numberposts=-1&post_status=publish&post_type=product' ); $choices = array(); foreach ( $posts as $post ) { $choices[] = array( 'text' => $post->post_title, 'value' => $post->post_title ); } // update 'Select a Post' to whatever you'd like the instructive option to be $field->placeholder = 'Select a product'; $field->choices = $choices; } return $form;}

只需稍微修改您的代碼，將第一列作為選擇字段，并動態(tài)填充產(chǎn)品名稱，就不會顯示很長的列表。
add_filter( 'gform_column_input_4_11_1', 'set_column', 10, 5 );
function set_column( $input_info, $field, $column, $value, $form_id ) {
global $current_user;
get_currentuserinfo();
$statuses = array('publish', 'draft');
// Args on the main query for WC_Product_Query
$args = [
'status' => $statuses,
'orderby' => 'name',
'order' => 'ASC',
'limit' => -1,
];
$vendor_products = wc_get_products($args);
$choices = array();
foreach ($vendor_products as $key => $product) {
if ($product->get_type() == "variable") {
// Args on product variations query for a variable product using a WP_Query
$args2 = array(
'post_parent' => $product->get_id(),
'post_type' => 'product_variation',
'orderby' => array( 'menu_order' => 'ASC', 'ID' => 'ASC' ),
'fields' => 'ids',
'post_status' => $statuses,
'numberposts' => -1,
);
foreach ( get_posts( $args2 ) as $child_id ) {
// get an instance of the WC_Variation_product Object
$variation = wc_get_product( $child_id );
if ( ! $variation || ! $variation->exists() ) {
continue;
}
$choices[] = array( 'text' => $product->get_name() . " - " . $child_id, 'value' => $product->get_name() . " - " . $child_id );
}
} else {
$choices[] = array( 'text' => $product->get_name(), 'value' => $product->get_name() );
}
}
return array( 'type' => 'select', 'choices' => $choices );
}

如果有人感興趣，這是我的工作代碼。
從這里得到一些很大的幫助：https://stackoverflow.com/a/61098114/1788961
add_filter( 'gform_field_value_list', 'populate_list' );
function populate_list( $value ) {
global $current_user;
get_currentuserinfo();
$statuses = array('publish', 'draft');
// Args on the main query for WC_Product_Query
$args = [
'status' => $statuses,
'orderby' => 'name',
'order' => 'ASC',
'limit' => -1,
];
$vendor_products = wc_get_products($args);
$list_array = array();
foreach ($vendor_products as $key => $product) {
if ($product->get_type() == "variable") {
// Args on product variations query for a variable product using a WP_Query
$args2 = array(
'post_parent' => $product->get_id(),
'post_type' => 'product_variation',
'orderby' => array( 'menu_order' => 'ASC', 'ID' => 'ASC' ),
'fields' => 'ids',
'post_status' => $statuses,
'numberposts' => -1,
);
foreach ( get_posts( $args2 ) as $child_id ) {
// get an instance of the WC_Variation_product Object
$variation = wc_get_product( $child_id );
if ( ! $variation || ! $variation->exists() ) {
continue;
}
$list_array[] = array(
'SKU' => $variation->get_sku(),
'Name' => $product->get_name() . " - " . $child_id,
);
}
} else {
$list_array[] = array(
'SKU' => $product->get_sku(),
'Name' => $product->get_name(),
);
}
}
return $list_array;
}
