1. 使用getQuery方法 可以使用getQuery方法获取查询构造器的实例并使用wheres属性来获取所有where条件然后使用reset方法重置条件。 $query Model::where(column1, value1)-orWhere(column2, value2);
// 获取查询构造器实例
$builder $query-getQuery();
// 清除所有 where 条件
$builder-wheres [];2. 创建新的查询构造器实例
$query Model::query(); // 创建新的查询构造器实例
$query $query-where(column1, value1)-orWhere(column2, value2);
// 下一次查询时创建新的查询构造器实例
$query Model::query();
3. 使用闭包
$query Model::query();
$query $query-where(function ($query) {$query-where(column1, value1)-orWhere(column2, value2);
});
// 下一次查询时不添加任何条件
$query Model::query();
4.如果你想清空某个字段的查询条件可以使用getQuery方法获取查询构造器的实例并使用wheres属性来获取所有的where条件然后遍历条件数组找到需要清空的条件并删除。
以下是一个示例代码片段演示如何清空某个字段的查询条件
$query Model::where(column1, value1)-where(column2, value2)-where(column3, value3);
// 获取查询构造器实例
$builder $query-getQuery();
// 获取所有 where 条件
$wheres $builder-wheres;// 遍历条件数组
foreach ($wheres as $key $where) {// 检查条件是否为字段 column2if (isset($where[column]) $where[column] column2) {// 删除条件unset($wheres[$key]);}
}// 重新设置查询构造器的 wheres 属性
$builder-wheres $wheres;// 执行查询
$results $query-get();
在上面的示例中我们首先获取查询构造器实例然后获取所有的where条件并遍历条件数组。如果条件的字段等于 column2我们就删除该条件。最后我们重新设置查询构造器的 wheres 属性并执行查询。
请根据你的具体需求修改示例代码以适应你的查询条件和模型。 public function likeVisit(Request $request){$userId $request-user()-id;$params $request-all();$page $params[page] ?? self::PAGE;$limit $params[limit] ?? self::LIMIT;$type $params[type] ??
