WordPress：在 Gravity 中使用 WooCommerce 產品填充列表字段 Forms

Question

我想讓用戶 select 產品在一個表格中。 為此，我需要使用已發布的 WooCommerce 產品動態填充表單。

我找到了一種使用 WooCommerce 產品填充 select 字段的解決方案。 但用戶應該能夠 select 每個產品的數量。 因此我需要使用列表字段並填充列表字段的單元格。

以下是列表字段的外觀：

SKU 和標題字段應動態填充。 數量字段供用戶填寫。

這是我用 WooCommerce 產品數據填充 select 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;
}

不幸的是，我不知道如何動態填充列表字段的單元格。

我找到了一個如何填充列表字段的示例： https://docs.gravityforms.com/gform_field_value_parameter_name/#list-field

但我不知道如何組合這兩個片段：/

add_filter( 'gform_field_value_list', 'populate_list' );
function populate_list( $value ) {
  $list_array = array(
            array(
                'Column 1' => 'row1col1',
                'Column 2' => 'row1col2',
                'Column 3' => 'row1col3',
            ),
            array(
                'Column 1' => 'row2col1',
                'Column 2' => 'row2col2',
                'Column 3' => 'row2col3'
            ),
  );
    return $list_array;
}

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;

}

只需稍微修改您的代碼以將第一列設為 select 字段並動態填充產品名稱以不顯示長列表。

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 );

}
