我需要在下面的代码中插入if
语句:
add_filter('add_to_cart_fragments', 'woocommerce_header_add_to_cart_fragment');
function woocommerce_header_add_to_cart_fragment( $fragments ) {
global $woocommerce;
ob_start();
?>
<a class="cart-contents" href="<?php echo $woocommerce->cart->get_cart_url(); ?>"
title="<?php _e('View your shopping cart', 'woothemes'); ?>">
<?php echo sprintf(_n('%d item', '%d items',
$woocommerce->cart->cart_contents_count, 'woothemes'),
$woocommerce->cart->cart_contents_count);?> -
<?php echo $woocommerce->cart->get_cart_total(); ?>
</a>
<?php
$fragments['a.cart-contents'] = ob_get_clean();
return $fragments;
}
这适用于woocommerce。它按内容编号显示购物车。
我需要一个类似于此的if
语句:
if ( sizeof( $woocommerce->cart->cart_contents ) == 0 ) {
echo 'empty cart';
}
else ...
因此,当购物车为空时,它会显示一条消息。我不知道如何将其写入该函数。
答案 0 :(得分:1)
替换:
<a class="cart-contents" href="<?php echo $woocommerce->cart->get_cart_url(); ?>"
title="<?php _e('View your shopping cart', 'woothemes'); ?>">
<?php echo sprintf(_n('%d item', '%d items',
$woocommerce->cart->cart_contents_count, 'woothemes'),
$woocommerce->cart->cart_contents_count);?> -
<?php echo $woocommerce->cart->get_cart_total(); ?>
</a>
<小时/> 有了这个:
<?php if((sizeof($woocommerce->cart->cart_contents)) == 0):
echo 'empty cart';
?>
<?php else: ?>
<a class="cart-contents" href="<?php echo $woocommerce->cart->get_cart_url(); ?>"
title="<?php _e('View your shopping cart', 'woothemes'); ?>">
<?php echo sprintf(_n('%d item', '%d items',
$woocommerce->cart->cart_contents_count, 'woothemes'),
$woocommerce->cart->cart_contents_count);?> -
<?php echo $woocommerce->cart->get_cart_total(); ?>
</a>
<?php endif; ?>
