Question

我需要woocommerce的座位预订扩展。由于大多数可用的插件都不适合或根本无法工作，所以我决定自己尝试一下。

创建字段（产品元数据）以存储预订的座位

add_action( 'woocommerce_product_data_panels', 'srd_seats' );
function srd_seats() {
    global $woocommerce, $post;

        ?><div id="srd_seating_data" class="panel woocommerce_options_panel"><?php
        woocommerce_wp_checkbox(
        array(
            'id'            => '_seat_1',
            'label'         => __('1', 'woocommerce' ),
            )
        );
            woocommerce_wp_checkbox(
        array(
            'id'            => '_seat_2',
            'label'         => __('2', 'woocommerce' ),
            )
        );
            woocommerce_wp_checkbox(
        array(
            'id'            => '_seat_3',
            'label'         => __('3', 'woocommerce' ),
            )
        );
            woocommerce_wp_checkbox(
        array(
            'id'            => '_seat_4',
            'label'         => __('4', 'woocommerce' ),
            )
        );
            woocommerce_wp_checkbox(
        array(
            'id'            => '_seat_5',
            'label'         => __('5', 'woocommerce' ),
            )
        );

保存数据

 add_action( 'woocommerce_process_product_meta', 'srd_seatings_save' );
function srd_seatings_save( $post_id ){

    $woocommerce_checkbox = isset( $_POST['_seat_1'] ) ? 'yes' : 'no';
    update_post_meta( $post_id, '_seat_1', $woocommerce_checkbox );
    $woocommerce_checkbox = isset( $_POST['_seat_2'] ) ? 'yes' : 'no';
    update_post_meta( $post_id, '_seat_2', $woocommerce_checkbox );
    $woocommerce_checkbox = isset( $_POST['_seat_3'] ) ? 'yes' : 'no';
    update_post_meta( $post_id, '_seat_3', $woocommerce_checkbox );
    $woocommerce_checkbox = isset( $_POST['_seat_4'] ) ? 'yes' : 'no';
    update_post_meta( $post_id, '_seat_4', $woocommerce_checkbox );
    $woocommerce_checkbox = isset( $_POST['_seat_5'] ) ? 'yes' : 'no';
    update_post_meta( $post_id, '_seat_5', $woocommerce_checkbox );

在结帐页面上作为复选框输出 将所有值输出为复选框：预订的座位会得到特殊处理，因此会被禁用。

add_action( 'woocommerce_before_order_notes' , 'srd_seat_reservation');

function srd_seat_reservation($checkout){

    // Loop through cart item quantity
    foreach( WC()->cart->get_cart() as $cart_item ) {

        $seats = array( '_seat_1',
                        '_seat_2',
                        '_seat_3',
                        '_seat_4',
                        '_seat_5',
                            );

        foreach ($seats as $seat) {
        $seatnumber = preg_replace('/[^0-9.]+/', '', $seat);
        if ( get_post_meta( $cart_item[ 'product_id' ], $seat, true) == 'yes'){
            echo '<input type="checkbox" disabled="disabled" checked="checked">'.$seatnumber.'<br>';}
            else {
            echo '<input type="checkbox" name="checkboxseat[]" value="'.$seatnumber.'">'.$seatnumber.'<br>';
                        }
            }
    }
}

验证所选字段 客户需要选择与购物车中物品数量完全相同的座位。

    add_action('woocommerce_checkout_process', 'srd_seating_process');
function srd_seating_process() {
        $quantity = WC()->cart->get_cart_contents_count(); // Get cart quantity
        $checked_arr = count($_POST['checkboxseat']); // Get Number of checked Checkboxes

        if ($quantity > $checked_arr)
                wc_add_notice( __( 'Bitte wählen Sie für jeden Teilnehmer einen Sitzplatz.', 'woocommerce' ), 'error' );
        if ($quantity < $checked_arr)
                wc_add_notice( __( 'Sie haben zu viele Sitzplätze ausgewählt.', 'woocommerce' ), 'error' );
}

我的问题，下一步是将所有选定复选框的值（$ seatnumber）保存到订单meta并更新产品meta。我正在努力收集选定的复选框并保存值。请在下面查看我为实现它的尝试。任何帮助深表感谢！ =）

add_action('woocommerce_checkout_create_order', 'srd_seating_create_order', 20, 2 );
function srd_seating_create_order( $order, $data ) {


    foreach($_POST['checkboxseat'] as $check) {
                $order->update_meta_data( 'Sitzplatz' , $check );
        }
}

我更喜欢在than in your last related question这个线程中回答。

您说您的代码有效，但是存在一些错误和疏忽，因此这里是完整的重新访问的代码，它将真正保存数据到订单并在各处显示：

1）在产品后端（设置）：

// Add a custom tab to product pages settings
add_filter( 'woocommerce_product_data_tabs', 'add_custom_product_tab_settings' , 99 , 1 );
function add_custom_product_tab_settings( $product_data_tabs ) {
    $product_data_tabs['seats'] = array(
        'label' => __( 'Seats', 'my_text_domain' ),
        'target' => 'seats_content',
    );
    return $product_data_tabs;
}

// The content of your custom product tab
add_action( 'woocommerce_product_data_panels', 'custom_product_tab_settings_content' );
function custom_product_tab_settings_content() {
    global $post;

    echo '<div id="seats_content" class="panel woocommerce_options_panel"><div class="options_group">';

    $seats_number = (int) get_post_meta( $post->ID, '_seats', true );

    $style1 = 'style="font-size:14px;font-weight:bold;"';
    $style2 = 'style="color:#E32636;"';
    $style3 = 'style="font-size:14px;font-style:italic;"';

    if( ! ( $seats_number > 0 ) ) {
        echo "<p $style1>" . sprintf( __('First, %s and %s (save)', 'woocommerce'),
        "<span $style2>" . __('define the number of seats', 'woocommerce') . "</span>",
        "<span $style2>" . __('Click on "Update"', 'woocommerce') . "</span>" ) . "</p>";
    }

    // Set the number of seats
    woocommerce_wp_text_input( array(
        'id'     => '_seats',
        'label'  => __('Number of seats'),
        'type'   => 'number',
        'value'  => ( $seats_number > 0 ? $seats_number : 0 ),
    ));

    echo '</div><div class="options_group">';

    if( $seats_number > 0 ) {
        // Loop through defined seats and display a checkbox for each
        for ( $i = 1; $i <= $seats_number; $i++) {
            woocommerce_wp_checkbox( array(
                'id'            => '_seat_'.$i,
                'label'         => $i,
            ));
        }
    } else {
        echo "<p $style3>" . __('No defined seats number yet', 'woocommerce') . '</p>';
    }
    echo '</div></div>';
}

// Saving the data from your custom tab fields settings
add_action( 'woocommerce_process_product_meta', 'save_custom_product_data' );
function save_custom_product_data( $post_id ){
    if( isset($_POST['_seats']) ){
        // Update the seats number
        update_post_meta( $post_id, '_seats', esc_attr($_POST['_seats']) );

        // Loop through seats
        for ( $i = 1; $i <= esc_attr($_POST['_seats']); $i++) {
            $value = isset( $_POST['_seat_'.$i] ) ? 'yes' : 'no';
            update_post_meta( $post_id, '_seat_'.$i, $value );
        }
    }
}

a）第一步：您必须首先设置产品的席位数量（当值为零时，没有复选框字段并保存。

b）第二步现在，您将获得与座位数相对应的复选框数量：

2）前端-结帐页面上（显示可用的可预订座位字段）：

add_action( 'woocommerce_before_order_notes' , 'checkout_seats_reservation'); function checkout_seats_reservation($checkout){ $item_count = 0; echo '<h3 id="booking-seats">'.__("Book your purchased seats", "Woocommerce").'</h3>'; // Loop through cart item quantity foreach( WC()->cart->get_cart() as $cart_item ) { $item_count++; $pid = $cart_item['product_id']; // The product Id echo '<div class="item-seats item-'.$item_count.' product-'.$pid.'"> <p>Item '.$item_count.': "'. $cart_item['data']->get_name().'" <em>(Purchased seats: <strong>'.$cart_item['quantity'].'</strong>)<em><p> <ul style="list-style: none">'; // Get the number of seats for the current item (product) $seats_number = get_post_meta( $pid, '_seats', true ); for ( $i = 1; $i <= $seats_number; $i++) { if ( get_post_meta( $pid, '_seat_'.$i, true) === 'yes') { echo '<li><input type="checkbox" disabled="disabled" checked="checked"><label>'.$i.'</label></li>'; } else { echo '<li><input type="checkbox" name="checkboxseat_'.$pid.'[]" value="'.$i.'"><label>'.$i.'</label></li>'; } } echo '<ul></p></div>'; } } // Checkout Fields validation add_action('woocommerce_checkout_process', 'seats_checkout_fields_validation'); function seats_checkout_fields_validation() { $cart = WC()->cart; $quantity = $cart->get_cart_contents_count(); // Get cart quantity $seats_count = 0; $unavailable = false; // Loop through cart items foreach( $cart->get_cart() as $cart_item ){ $pid = $cart_item['product_id']; // The product ID if( isset($_POST['checkboxseat_'.$pid]) ){ $checkboxseat = (array) $_POST['checkboxseat_'.$pid]; // Loop through selected foreach( $checkboxseat as $seat ) { // Check that selected seats are still available when order is submitted if ( get_post_meta( $pid, '_seat_'.$seat, true) === 'yes') { $unavailable = true; break; } $seats_count++; } } } if( $unavailable ) { wc_add_notice( __( 'Error: Some selected seats are not available anymore.', 'woocommerce' ), 'error' ); } elseif ( $quantity > $seats_count ) { wc_add_notice( __( 'Bitte wählen Sie für jeden Teilnehmer einen Sitzplatz.', 'woocommerce' ), 'error' ); } elseif ( $quantity < $seats_count ) { wc_add_notice( __( 'Sie haben zu viele Sitzplätze ausgewählt.', 'woocommerce' ), 'error' ); } }

在结帐页面上，其中出现复选框的是（这里有2个项目）：

3）保存提交的数据到订购，更新相关产品并在任何地方显示所选席位：

// Update the order meta data with the chosen seats raw array data add_action('woocommerce_checkout_create_order', 'save_seats_reservation_to_order_and_update_product', 10, 2); function save_seats_reservation_to_order_and_update_product( $order, $data ) { $seats_arr = array(); // Loop through order items foreach( $order->get_items() as $item ) { $pid = $item->get_product_id(); if( isset( $_POST['checkboxseat_'.$pid]) ) { $seats = (array) $_POST['checkboxseat_'.$pid]; // Loop through submitted seats foreach ( $seats as $seat ){ // Update seats data in the product update_post_meta( $pid, '_seat_'.$seat, 'yes' ); } // Set and format our main array with the order item chosen seats $seats_arr[] = $seats; } } // Save selected seats multi-dimentional array data $order->update_meta_data( '_sitzplatz', $seats_arr ); } // Save chosen seats to each order item as custom meta data and display order items chosen seats everywhere add_action('woocommerce_checkout_create_order_line_item', 'save_order_item_seats_reservation', 10, 4 ); function save_order_item_seats_reservation( $item, $cart_item_key, $values, $order ) { // Get the chosen seats data from the order if( isset( $_POST['checkboxseat_'.$item->get_product_id()]) ) { $sitzplatz = $_POST['checkboxseat_'.$item->get_product_id()]; $value = implode( ', ', $sitzplatz ); // Save selected item seats to each order item as custom meta data $item->update_meta_data( __('Sitzplatz'), $value ); } }

收到订单（谢谢）：

关于电子邮件通知：

在管理订单编辑页面上：

所有代码都放在活动子主题（或活动主题）的function.php文件中。经过测试，可以正常工作。

您应该对样式进行一些重新设计，以使其更加美观。

// Update the order meta with the seats chosen
add_action('woocommerce_checkout_create_order', 'srd_seat_create_order', 20, 2);
function srd_seat_create_order( $order, $data ) {
    $checks = $_POST['checkboxseat'];

    foreach( WC()->cart->get_cart() as $cart_item ) {
        foreach ($checks as $check){
            $order->update_meta_data( '_sitzplatz'.$check , $check);
            update_post_meta( $cart_item[ 'product_id'], $check , 'yes' );
        }
    }}
