我有以下查询构建器生成此查询:
当使用最小和最大价格过滤时,我的问题在于销售和库存选项中的where条件。我的网址如下所示:
category/men-clothes?sale=no_sale&min_price=10&max_price=10000&per_page=8
sale = no_sale,表示查询执行where' sale_price',' =',0,因此这在我的SQL查询中:
and `sale_price` = ? order by `id` desc
然而,它仍然提取sales_price大于0的产品,但是当我切换到on_sale时,只提取sales_price大于0的产品。所以问题只在选择没有活跃销售的产品时。 对于on_stock和no_stock来说,它只是没有获取正确的产品。我知道建造者很大,但我还没能弄清楚它为什么不能正常工作。它只有在我完全删除min_price和max_price过滤后才能正常工作所以它必须位于导致这些问题的价格过滤的where和orWhere中。

我认为这里的问题是orWhere
。当你使用orWhere时,你应该总是用额外的封闭包裹结构。我们来看看:
->when($minPrice, function ($query) use ($data) {
$query->where([
['has_variants', '=', 0],
['price', '>=', $data['active_filters']['min_price']],
])
->orWhere([
['has_variants', '=', 1],
['min_price', '!=', 0],
['min_price', '>=', $data['active_filters']['min_price']],
]);
})
这部分可能看起来像这样:
->when($minPrice, function ($query) use ($data) {
$query->where(function($query) use ($data) {
$query->where([
['has_variants', '=', 0],
['price', '>=', $data['active_filters']['min_price']],
])
->orWhere([
['has_variants', '=', 1],
['min_price', '!=', 0],
['min_price', '>=', $data['active_filters']['min_price']],
]);
});
})
如上所述,整个where .. orWhere
被包裹在另外的封闭中。
原因很明显。如果你没有额外的闭包,你可以产生这样的查询
WHERE A and B or C and D or E
通常它应该是这样的:
WHERE A and (B or C) and (D or E)
所以当你使用闭包时,他们会在查询中添加额外的括号以使其有效。
同样地,您应该显然包装所有其他where ... orWhere
构造以使其按预期工作
