CakePHP 3.6 Query Builder complex OR conditions issue - cakephp-3.0

Question

I am trying to build a query using query builder with complex nested AND and OR conditions. Here is what I have written so far.
$cond_arr = array();
$cond_arr['VehicleBrandModels.status'] = 1;
$query = $this->VehicleBrandModels->find();
$query->hydrate(false);
$query->select($this->VehicleBrandModels);
$query->where($cond_arr);
$VBM_data = $query->toArray();
This will generate a query like below
SELECT * FROM vehicle_brand_models WHERE status = 1;
I want to generate a query with nested AND & OR conditions like below
SELECT * FROM vehicle_brand_models WHERE status = 1 AND ((overall_rating > 0 AND overall_rating < 2) OR (overall_rating >= 2 AND overall_rating < 4) OR (overall_rating >= 4 AND overall_rating <= 5));
Can anybody help to solve how to achieve this in CAKEPHP 3.0 Query builder?

Answer 1

The simplest solution is the following
$cond_arr = [
'VehicleBrandModels.status' => 1,
'OR' => [
['overall_rating >' => 0, 'overall_rating <' => 2],
['overall_rating >=' => 2, 'overall_rating <' => 4],
['overall_rating >=' => 4, 'overall_rating <=' => 5]
]
];
there is a more 'cake' way and if I'll have time I will post it.
But note that from what I see all your OR conditions overlap and you can simply do
$cond_arr = [
'VehicleBrandModels.status' => 1,
'overall_rating >' => 0,
'overall_rating <=' => 5
];
edit: as primised here's the more cake way using query expressions
$query->where(function($exp, $q) {
$exp = $exp->eq('VehicleBrandModels.status', 1);
$conditions1 = $exp->and_([])
->gt('overall_rating ', 0)
->lte('overall_rating ', 2);
$conditions2 = $exp->and_([])
->gt('overall_rating ', 2)
->lte('overall_rating ', 4);
$conditions3 = $exp->and_([])
->gt('overall_rating ', 4)
->lte('overall_rating ', 5);
$orConditions = $exp->or_([$conditions1, $conditions2, $conditions3]);
$exp->add($orConditions);
return $exp;
});
still some conditions are overlapping
