Question

当我保存第一个产品变体字段时，它们会被保存，但当我尝试保存第二个，第三个，第四个以及更远时，它们不会被保存。

我正在填写每个产品变体的SKU，所以它应该工作。但是，这是我在这里缺少的东西？这是最新的WordPress和最新的WooCommerce版本。

//Display Fields
add_action( 'woocommerce_product_after_variable_attributes', 'variable_fields', 10, 3 );

//Save variation fields
add_action( 'woocommerce_save_product_variation', 'save_variable_fields', 10, 1 );


/**
 * Create new fields for variations
 *
 */
function variable_fields( $loop, $variation_data, $variation ) {
?>
<tr>
    <td>
        <?php
        // Textarea
        woocommerce_wp_textarea_input(
            array(
                'id'          => '_textarea['.$loop.']',
                'label'       => __( 'Contains', 'woocommerce' ),
                'placeholder' => '',
                'description' => __( '<br />Contains', 'woocommerce' ),
                'value'       => get_post_meta( $variation->ID, '_textarea', true ),
            )
        );
        ?>
    </td>
</tr>

<tr>
    <td>
        <?php
        // Textarea
        woocommerce_wp_textarea_input(
            array(
                'id'          => '_textarea_2['.$loop.']',
                'label'       => __( 'Observation message', 'woocommerce' ),
                'placeholder' => '',
                'description' => __( '<br />Observation message', 'woocommerce' ),
                'value'       => get_post_meta( $variation->ID, '_textarea_2', true ),
            )
        );
        ?>
    </td>
</tr>

<?php
}


/**
 * Save new fields for variations
 *
 */
function save_variable_fields( $post_id ) {
    if (isset( $_POST['variable_sku'] ) ) :

        $variable_sku          = $_POST['variable_sku'];
        $variable_post_id      = $_POST['variable_post_id'];

        // Textarea
        $_textarea = $_POST['_textarea'];
        for ( $i = 0; $i < sizeof( $variable_sku ); $i++ ) :
            $variation_id = (int) $variable_post_id[$i];
            if ( isset( $_textarea[$i] ) ) {
                update_post_meta( $variation_id, '_textarea', stripslashes( $_textarea[$i] ) );
            }
        endfor;


        // Textarea
        $_textarea_2 = $_POST['_textarea_2'];
        for ( $i = 0; $i < sizeof( $variable_sku ); $i++ ) :
            $variation_id = (int) $variable_post_id[$i];
            if ( isset( $_textarea_2[$i] ) ) {
                update_post_meta( $variation_id, '_textarea_2', stripslashes( $_textarea_2[$i] ) );
            }
        endfor;

    endif;
}

我已修改动作＆amp;保存功能：

//Save variation fields
add_action( 'woocommerce_save_product_variation', 'save_variable_fields', 10, 2 );
/**
 * Save new fields for variations
 *
 */
function save_variable_fields( $variation_id, $i ) {
    if ( empty( $variation_id ) ) return;
    if ( isset( $_POST['_textarea'][$i] ) ) {
        update_post_meta( $variation_id, '_textarea', stripslashes( $_POST['_textarea'][$i] ) );
    }
    if ( isset( $_POST['_textarea_2'][$i] ) ) {
        update_post_meta( $variation_id, '_textarea_2', stripslashes( $_POST['_textarea_2'][$i] ) );
    }
}
