如何覆盖 laravel 查询构建器对象中的 where 子句？

Question

Example I have query builder object

$queryBuilder = Products::where('price', '>', 100);

But if I need change where clauses to example - where('price', '<', 100).
How can I overwrite current where clauses in this object? Is it has way?

Answer 1

Use Laravel conditional Clause

 ->when($yourCondition, function ($query) {
       $query->where('price', '>', 100);
  }, function ($query) {
       $query->where('price', '<', 100);
 })
