我有这样的SSRS表达式：
null如果表达式等于Format，我尝试显示0作为此问题的其他答案我尝试#,##0自定义数字属性为：if($product->is_type('variable')){
foreach($product->get_available_variations() as $variation ){
// Variation ID
$variation_id = $variation['variation_id'];
echo '<div class="product-variation variation-id-'.$variation_id.'">
<strong>Variation id</strong>: '.$variation_id.'<br>';
// Attributes
$attributes = array();
foreach( $variation['attributes'] as $key => $value ){
$taxonomy = str_replace('attribute_', '', $key );
$taxonomy_label = get_taxonomy( $taxonomy )->labels->singular_name;
$term_name = get_term_by( 'slug', $value, $taxonomy )->name;
$attributes[] = $taxonomy_label.': '.$term_name;
}
echo '<span class="variation-attributes">
<strong>Attributes</strong>: '.implode( ' | ', $attributes ).'</span><br>';
// Prices
$active_price = floatval($variation['display_price']); // Active price
$regular_price = floatval($variation['display_regular_price']); // Regular Price
if( $active_price != $regular_price ){
$sale_price = $active_price; // Sale Price
}
echo '<span class="variation-prices">
<strong>Price</strong>: '.$variation['price_html'].'</span><br>
</div>';
}
}
，但它不起作用。有人可以帮助我如何实现这一目标？此致
答案 0 :(得分：0)
如果您正在测试null的整个表达式，那么您可能需要这样的东西..
{{1}}
