[英]Custom form fields in cart and get the data in checkout on Woocommerce
在结帐之前在购物车页面中添加“从”,“到”和“消息”字段。我已经在cart.php文件中添加了一些代码,但是在添加该代码之后,购物车页面显示为空白。
/**
* Add the order_comments field to the cart
**/
add_action('woocommerce_cart_collaterals',
'order_comments_custom_cart_field');
function order_comments_custom_cart_field() {
echo '<div id="cart_order_notes">';
?>
<div class="customer_notes_on_cart">
<label for="customer_notes_text"><?php _e('Order notes','woocommerce'); ?>
</label>
<textarea id="customer_notes_text"></textarea>
</div>
<?php
}
/**
* Process the checkout and overwriting the normal button
*
*/
function woocommerce_button_proceed_to_checkout() {
$checkout_url = wc_get_checkout_url();
?>
<form id="checkout_form" method="POST" action="<?php echo $checkout_url;
?>">
<input type="hidden" name="customer_notes" id="customer_notes" value="">
<a href="#" onclick="document.getElementById('customer_notes').value=document.getElementById('customer_notes_text').value;document.getElementById('checkout_form').submit()" class="checkout-button button alt wc-forward">
<?php _e( 'Proceed to checkout', 'woocommerce' ); ?></a>
</form>
<?php
}
// getting the values in checkout again
add_action('woocommerce_checkout_before_customer_details',function(){
?>
<script>
jQuery( document ).ready(function() {
jQuery('#order_comments' ).val("<?php echo
sanitize_text_field($_POST['customer_notes']); ?>");
});
</script>
<?php
});
在cart.php中,我在关闭form标签之前和form标签之后在底部添加了此代码。但是在cart.php中添加了这段代码后,我得到了空白页面。
我试图以相同的格式将那些从,到和消息字段中获取。
以下代码将从购物车页面中的自定义textarea字段发布估算的文本值到结帐订单备注字段:
// Add the order_comments field to the cart
add_action( 'woocommerce_cart_collaterals', 'order_comments_custom_cart_field' );
function order_comments_custom_cart_field() {
?>
<div class="customer_notes_on_cart" style="clear:both;">
<label for="customer_notes_text"><?php _e("Order notes", "woocommerce") ?></label>
<textarea id="customer_notes_text"></textarea></div>
<?php
}
// Process the checkout and overwriting the normal button
add_action( 'woocommerce_proceed_to_checkout', 'change_proceed_to_checkout', 15 );
function change_proceed_to_checkout() {
remove_action( 'woocommerce_proceed_to_checkout', 'woocommerce_button_proceed_to_checkout', 20 );
?>
<form id="checkout_form" method="POST" action="<?php echo wc_get_checkout_url(); ?>">
<input type="hidden" name="customer_notes" id="customer_notes" value="">
<button type="submit" class="checkout-button button alt wc-forward" style="width:100%;"><?php
esc_html_e( 'Proceed to checkout', 'woocommerce' ) ?></button>
</form>
<?php
}
// Jquery script for cart and checkout pages
add_action('wp_footer', 'customer_notes_jquery' );
function customer_notes_jquery() {
?>
<script>
jQuery(function($) {
<?php // For cart
if( is_cart() ) : ?>
$('#customer_notes_text').on( 'blur', function(){
$('#customer_notes').val($(this).val());
});
<?php // For checkout
elseif( is_checkout() && ! is_wc_endpoint_url() ) : ?>
$('#order_comments' ).val("<?php echo sanitize_text_field($_POST['customer_notes']); ?>");
<?php endif; ?>
});
</script>
<?php
}
代码进入您的活动子主题(或活动主题)的function.php文件中。 经过测试和工作。
我认为最好不要进行“结帐”表单更改,最好将字段中的数据更改时将vars存储在localstorage中,然后在用户处于结帐表单时获取它。
function order_comments_custom_cart_field() {
echo '<div id="cart_order_notes">';
?>
<div class="customer_notes_on_cart">
<label for="customer_notes_text"><?php _e('Order notes','woocommerce'); ?>
</label>
<textarea id="customer_notes_text"></textarea>
</div>
<script>
jQuery(document).ready(function (jQuery) {
jQuery("#customer_notes_text").on('change', function () {
localStorage.setItem(jQuery(this).attr('id'), this.val());
});
});
</script>
<?php
}
然后你可以得到它
LocalStore.getItem(项目);
别忘了在获得元素后销毁它,
LocalStorage.removeItem(项目);
