php - 如何从购物车页面的输入字段到管理订单详细信息页面获取值(value)？

Question

在购物车页面中，我已经创建了两个文本字段，但我无法获取用户在该字段中输入到管理订单详细信息页面的值。

如何获取订单详细信息页面中的值，我还想将该详细信息保存在数据库中。

下面是我的购物车页面的代码

<?php

do_action( 'woocommerce_before_cart' ); ?>
    <section class="checkout_display">
        <div class="container">
            <div class="row">

显示文本字段 1 和 2 的代码是我想从中获取用户输入的值并希望在完成付款后将其显示并存储在管理订单详细信息页面中的文本框

尝试以下将向 Woocommerce session 显示您发布的字段值。下订单时，它会将自定义 session 数据保存为自定义订单元数据，并将其显示在管理订单中:

// Save the posted data to Woocommerce session
add_filter( 'init', 'set_instagram_posted_data_to_wc_sessions', 10, 3 );
function set_instagram_posted_data_to_wc_sessions() {

    if ( ( is_cart() || is_checkout() ) && isset($_POST['igusername']) && isset($_POST['useremail']) ) {
        // Enable Woocommerce sessions (if not done yet)
        if ( isset(WC()->session) && ! WC()->session->has_session() ) {
            WC()->session->set_customer_session_cookie( true );
        }

        $session_data = []; // initializing

        if( isset($_POST['igusername']) && ! empty($_POST['igusername']) ) {
            // Add the dropdown value as custom cart item data
            $session_data['ig_username'] = sanitize_text_field($_POST['igusername']);
        }

        if( isset($_POST['useremail']) && ! empty($_POST['useremail']) ) {
            // Add the dropdown value as custom cart item data
            $session_data['ig_useremail'] = sanitize_email($_POST['useremail']);
        }

        // Set the data to custom wc_sessions
        if( sizeof($session_data) > 0 ) {
            WC()->session->set('ig_data', $session_data);
        }
    }
}

// Save the session data as custom order meta data (post meta data)
add_action( 'woocommerce_checkout_create_order', 'action_checkout_create_order_callback', 10, 2 );
function action_checkout_create_order_callback( $order, $data ) {
    if( $session_data = WC()->session->get('ig_data') ) {
        $order->update_meta_data( '_ig_username', wc_clean($session_data['ig_username']) );
        $order->update_meta_data( '_ig_useremail', wc_clean($session_data['ig_useremail']) );
        
        // remove the data from Woocommerce session
         WC()->session->__unset('ig_data'):
    }
}


// Display custom data in Admin orders, below the billing address
add_action( 'woocommerce_admin_order_data_after_billing_address', 'display_after_admin_order_billing_address', 10, 1 );
function display_after_admin_order_billing_address( $order ){
    $ig_username = $order->get_meta('_ig_username');
    $ig_useremail = $order->get_meta('_ig_useremail');

    if( ! empty($ig_username) || ! empty($ig_useremail) ) :

    echo '<div class="instagram-userdata">
        <h3>'.__('Instagram user data').'</h3>
        <table cellpadding="0" cellspacing="0" border="0" style="margin-top:6px;">
            <tr><th align="left">'.__('Username').':&nbsp;</th><td>&nbsp;' . $ig_username . '</td></tr>
            <tr><th align="left">'.__('Email').':&nbsp;</th><td>&nbsp;' . $ig_useremail . '</td></tr>
        </table>
    </div>';

    endif;
}

代码进入事件子主题(或事件主题)的 function.php 文件。它现在应该可以工作了。

如果它不适用于 session ，您可以使用以下方法将发布数据添加到结帐页面的隐藏字段，并在提交订单时再次发布该数据……其他一切都与上面相同……

所以你可以换个方式试试:

// Display the posted data values in checkout hidden fields
add_filter( 'woocommerce_after_checkout_billing_form', 'set_instagram_posted_data_in_hidden_field', 10, 3 );
function set_instagram_posted_data_in_hidden_field() {

    if ( isset($_REQUEST['igusername'])|| isset($_REQUEST['useremail']) ) {
        // Display hidden fields with the Instagram posted values
        ?><input type="hidden" name="ig_username" value="<?php echo $_REQUEST['igusername']; ?>">
        <input type="hidden" name="ig_useremail" value="<?php echo $_REQUEST['useremail']; ?>"><?php
    }
}

// Save checkout hidden fields values as custom order meta data (post meta data)
add_action( 'woocommerce_checkout_create_order', 'action_checkout_create_order_callback', 10, 2 );
function action_checkout_create_order_callback( $order, $data ) {
    if ( isset($_POST['ig_username']) {
        $order->update_meta_data( '_ig_username', sanitize_text_field($_POST['ig_username']) );
    }
    if ( isset($_POST['ig_useremail']) {
        $order->update_meta_data( '_ig_useremail', sanitize_email($session_data['ig_useremail']) );
    }
}


// Display custom data in Admin orders, below the billing address
add_action( 'woocommerce_admin_order_data_after_billing_address', 'display_after_admin_order_billing_address', 10, 1 );
function display_after_admin_order_billing_address( $order ){
    $ig_username = $order->get_meta('_ig_username');
    $ig_useremail = $order->get_meta('_ig_useremail');

    if( ! empty($ig_username) || ! empty($ig_useremail) ) :

    echo '<div class="instagram-userdata">
        <h3>'.__('Instagram user data').'</h3>
        <table cellpadding="0" cellspacing="0" border="0" style="margin-top:6px;">
            <tr><th align="left">'.__('Username').':&nbsp;</th><td>&nbsp;' . $ig_username . '</td></tr>
            <tr><th align="left">'.__('Email').':&nbsp;</th><td>&nbsp;' . $ig_useremail . '</td></tr>
        </table>
    </div>';

    endif;
}

在后端的订单页面中，您会得到如下内容:

---

从 $order WC_Order 对象 (或 $order_id Order Id) 使用:

$order = wc_get_order( $order_id ); // (optionally if required) with the Order ID

$ig_username  = $order->get_meta('_ig_username');
$ig_useremail = $order->get_meta('_ig_useremail');
