Laravel From RAW Query to Eloquent Query - php

Question

I'm trying to convert my Raw query to an eloquent query
You can see here
$data = DB::connection('mysql')->select("SELECT product.id, product.title, product.description, product.content, product.photo, product_per_category.productcategory_id, product.quantity, product.price
FROM product LEFT JOIN product_per_category ON product_per_category.product_id = product.id
WHERE product.deleted = 0 AND product_per_category.deleted = 0 AND productcategory_id = '$id' AND (product.title like '%$keyword%' OR product.content like '%$keyword%' OR product.price like '%$keyword%' OR product.quantity like '%$keyword%')
GROUP BY product.id");
I have multiple WHERE statement that combines with AND & OR inside of a parentheses
I just want to know if Im doing this right with my eloquent query like this
$data = DB::table('product')
->select('product.id','product.title','product.description','product.content','product.photo','product.quantity','product.price')
->join('product_per_category','product_per_category.product_id','=','product.id')
->where(['product.deleted' => 0])
->where(['product_per_category.deleted' => 0])
->where(['product_per_category.productcategory_id' => $id])
->orWhere('product.content', 'like', '%' . $keyword . '%')
->orWhere('product.title', 'like', '%' . $keyword . '%')
->orWhere('product.quantity', 'like', '%' . $keyword . '%')
->orWhere('product.price', 'like', '%' . $keyword . '%')
->groupBy('product.id')
->get();
Because I wonder in my query I have OR statement inside of a parentheses.
Which I combine them inside of the parentheses to make it only the fields optional with LIKE statement

Answer 1

You're pretty close, but when you need to have conditions between parenthesis, your where() functions should be a callback.
For example (product.title like '%$keyword%' OR product.content like '%$keyword%' OR product.price like '%$keyword%' OR product.quantity like '%$keyword%')
would be
$query->where(function($subquery) use($keyword) {
$subquery->where('title', 'like', "%{$keyword}%")
->orWhere('content', 'like', "%{$keyword}%");
});
This is only a rough example of your requirement, but you should get it.
Just so you know, you can combine almost ALL Eloquent functions.
Good luck!

Answer 2

You can pass a closure inside the where method.
The closure will receive a query builder instance which you can use to set the constraints that should be contained within the parenthesis.
This is known as parameter grouping.

Change your statement to this.
$data = DB::table('product')
->select('product.id','product.title','product.description','product.content','product.photo','product.quantity','product.price')
->join('product_per_category','product_per_category.product_id','=','product.id')
->where(['product.deleted' => 0])
->where(['product_per_category.deleted' => 0])
->where(['product_per_category.productcategory_id' => $id])
->where(function($query) use($keyword){
$query->where('product.content', 'like', '%' . $keyword . '%')
->orWhere('product.title', 'like', '%' . $keyword . '%')
->orWhere('product.quantity', 'like', '%' . $keyword . '%')
->orWhere('product.price', 'like', '%' . $keyword . '%');
})
->groupBy('product.id')
->get();
