Question

我有自定义字段和问题的问题我的产品页面上的值显示在购物车页面上。从截图中可以看出，我有三个字段：＆＃34; Color，＆＃34; ＆＃34; Texto1＆＃34;和＆＃34; Texto2＆＃34;只有第一个似乎出现在我的购物车页面上。

这是打印产品页面上字段的代码：

// Field 1
if( ! empty( $FieldType1 ) ){
    if( $FieldType1 == "TEXT AREA"){
    echo '<div>
        <label>'.$FieldName1.':<br></label> <textarea name="FieldTypeValue1" maxlength="'.$FieldLenght1.'" rows="2" cols="80" placeholder="" required></textarea>
    </div><br>';
    }

    if( $FieldType1 == "TEXT BOX"){
    echo '<div>
        <label>'.$FieldName1.':<br></label> <input type="text"  maxlength="'.$FieldLenght1.'" name="FieldTypeValue1" value="" required>
    </div><br>';
    }

    if( $FieldType1 == "DROP DOWN"){
        echo '<div>
        <label>'.$FieldName1.':<br></label>
        <select name="FieldTypeValue1">';
        foreach ($Dropdown1Content as $Dropdown1IndividualContent) {
        echo '<option>';
        echo $Dropdown1IndividualContent;
        echo '</option>';
        }

        echo '</select></div><br>';
    }
}

// Field 2  
if( ! empty( $FieldType2 ) ){
    if( $FieldType2 == "TEXT AREA"){
    echo '<div>
        <label>'.$FieldName2.':<br></label> <textarea name="FieldTypeValue2" maxlength="'.$FieldLenght2.'" rows="2" cols="80" placeholder="" required></textarea>
    </div><br>';
    }

    if( $FieldType2 == "TEXT BOX"){
    echo '<div>
        <label>'.$FieldName2.':<br></label> <input type="text"  maxlength="'.$FieldLenght2.'" name="FieldTypeValue2" value="" required>
    </div><br>';
    }

    if( $FieldType2 == "DROP DOWN"){
        echo '<div>
        <label>'.$FieldName2.':<br></label>
        <select name="FieldTypeValue2">';
        foreach ($Dropdown2Content as $Dropdown2IndividualContent) {
        echo '<option>';
        echo $Dropdown2IndividualContent;
        echo '</option>';
        }

        echo '</select></div><br>';
    }
}



// Field 3
if( ! empty( $FieldType3 ) ){
    if( $FieldType3 == "TEXT AREA"){
    echo '<div>
        <label>'.$FieldName3.':<br></label> <textarea name="FieldTypeValue3" maxlength="'.$FieldLenght3.'" rows="2" cols="80" placeholder="" required></textarea>
    </div><br>';
    }

    if( $FieldType3 == "TEXT BOX"){
    echo '<div>
        <label>'.$FieldName3.':<br></label> <input type="text"  maxlength="'.$FieldLenght3.'" name="FieldTypeValue3" value="" required>
    </div><br>';
    }

    if( $FieldType3 == "DROP DOWN"){
        echo '<div>
        <label>'.$FieldName3.':<br></label>
        <select name="FieldTypeValue3">';
        foreach ($Dropdown3Content as $Dropdown3IndividualContent) {
        echo '<option>';
        echo $Dropdown3IndividualContent;
        echo '</option>';
        }

        echo '</select></div><br>';
    }
}

这是保存产品页面上字段值的代码

// Store custom field label and value in cart item data
add_action( 'woocommerce_add_cart_item_data','save_my_custom_checkout_field', 10, 2 );
function save_my_custom_checkout_field( $cart_item_data, $product_id ) {
if( isset( $_REQUEST['FieldTypeValue1'] ) ) {
    $cart_item_data['custom_data']['label'] = get_post_meta($product_id, 'FieldName1', true);
    $cart_item_data['custom_data']['value'] = sanitize_text_field( $_REQUEST['FieldTypeValue1'] );
    $cart_item_data['custom_data']['ukey'] = md5( microtime().rand() );
}
return $cart_item_data;

if( isset( $_REQUEST['FieldTypeValue2'] ) ) {
    $cart_item_data['custom_data']['label'] = get_post_meta($product_id, 'FieldName2', true);
    $cart_item_data['custom_data']['value'] = sanitize_text_field( $_REQUEST['FieldTypeValue2'] );
    $cart_item_data['custom_data']['ukey'] = md5( microtime().rand() );
}
return $cart_item_data;

if( isset( $_REQUEST['FieldTypeValue3'] ) ) {
    $cart_item_data['custom_data']['label'] = get_post_meta($product_id,'FieldName3', true);
    $cart_item_data['custom_data']['value'] = sanitize_text_field( $_REQUEST['FieldTypeValue3'] );
    $cart_item_data['custom_data']['ukey'] = md5( microtime().rand() );
}
return $cart_item_data;

这是在购物车上打印价值的那个：

// Display items custom fields label and value in cart and checkout pages
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );
function render_meta_on_cart_and_checkout( $cart_data, $cart_item ){

$custom_items = array();

/* Woo 2.4.2 updates */
if( !empty( $cart_data ) ) {
    $custom_items = $cart_data;
}
if( isset( $cart_item['custom_data'] ) ) {
    $custom_items[] = array(
        'name' => $cart_item['custom_data']['label'],
        'value' => $cart_item['custom_data']['value'],
    );
}
return $custom_items;

}

产品页面上的自定义字段：

Product page

购物车中的产品（缺少数据）：

Product in cart

我不确定问题是在保存值的位置还是在打印它们的位置。

非常感谢任何帮助。

尝试使用这个钩子函数，我重新访问了代码以使其工作：

// Store custom field label and value in cart item data
add_filter( 'woocommerce_add_cart_item_data','save_my_custom_checkout_field', 20, 2 );
function save_my_custom_checkout_field( $cart_item_data, $product_id ) {
    $label1 = get_post_meta( $product_id, 'FieldName1', true );
    $label2 = get_post_meta( $product_id, 'FieldName2', true );
    $label3 = get_post_meta( $product_id, 'FieldName3', true );

    if( isset( $_REQUEST['FieldTypeValue1'] ) && ! empty( $label1 ) )
        $cart_item_data['custom_data']['1'] = array(
            'label' => $label1,
            'value' => sanitize_text_field( $_REQUEST['FieldTypeValue1'] ),
        );

    if( isset( $_REQUEST['FieldTypeValue2'] ) && ! empty( $label2 ) )
        $cart_item_data['custom_data']['2'] = array(
            'label' => $label2,
            'value' => sanitize_text_field( $_REQUEST['FieldTypeValue2'] ),
        );

    if( isset( $_REQUEST['FieldTypeValue3'] ) && ! empty( $label3 ) )
        $cart_item_data['custom_data']['3'] = array(
            'label' => $label3,
            'value' => sanitize_text_field( $_REQUEST['FieldTypeValue3'] ),
        );

    if( count($cart_item_data['custom_data']) > 0 )
        $cart_item_data['custom_data']['key'] = md5( microtime().rand() );

    return $cart_item_data;
}

// Display items custom fields label and value in cart and checkout pages
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 20, 2 );
function render_meta_on_cart_and_checkout( $cart_data, $cart_item ){
    $custom_items = array();

    if( !empty( $cart_data ) )
        $custom_items = $cart_data;

    if( isset( $cart_item['custom_data'] ) ) {
        foreach( $cart_item['custom_data'] as $key => $custom_data ){
            if( $key != 'key' ){
                $custom_items[] = array(
                    'name' => $custom_data['label'],
                    'value' => $custom_data['value'],
                );
            }
        }
    }
    return $custom_items;
}

代码进入活动子主题（或活动主题）的function.php文件。

经过测试和工作......你会得到类似的东西：

为了进行测试，我使用以下内容在单个产品页面上显示3个自定义字段：

// Displaying 3 custom fields on single product pages
add_action( 'woocommerce_before_add_to_cart_button', 'add_custom_fields_single_product', 20 );
function add_custom_fields_single_product(){
    global $product;

    echo '<div>
    <label>'.__('Color').': </label><br>
    <input type="text" name="FieldTypeValue1" value="" required>
</div><br>';
    echo '<div>
    <label>'.__('Texto 1').': </label><br>
    <input type="text" name="FieldTypeValue2" value="" required>
</div><br>';
    echo '<div>
    <label>'.__('Texto 2').': </label><br>
    <input type="text" name="FieldTypeValue3" value="" required>
</div><br>';
}

更改以下内容仅用于测试目的（在功能代码中）：

    $label1 = get_post_meta( $product_id, 'FieldName1', true );
    $label2 = get_post_meta( $product_id, 'FieldName2', true );
    $label3 = get_post_meta( $product_id, 'FieldName3', true );

由：

    $label1 = __('Color'); 
    $label2 = __('Texto 1'); 
    $label3 = __('Texto 2');

在Woocommerce上的购物车中显示多个产品自定义字段值
