Laravel Eloquent Many to Many Query - laravel

Question

Please help me make this query in eloquent. A business can have many categories.
SELECT b.*
FROM businesses b
INNER JOIN categorybusiness cb
ON b.id = cb.business_id
INNER JOIN category c
ON cb.category_id = c.id
WHERE b.location LIKE '%query1%'
AND b.location LIKE '%query2%'
AND c.name LIKE '%query3%'
AND c.name LIKE '%query4%'
my tables are.. businesses - contain the location column and a pivot table for category and business..
UPDATE:
so i used this query...
$business5 = Business::WhereHas('categories', function($q) use($category,$query1)
{
$q->whereRaw("name like '%$category%' or businesses.name like '%$category%' $query1");
})->get();
$query1 looks like this but in a loop.
$query1 .= " and businesses.address1 like '%$string%'";
It's working fine but can someone help me make a "MATCH AGAINST" statement in eloquent from this.

Answer 1

For making an Eloquent query you need to setup relationship and to create a many-to-many relationship you need to build the relationship like this in both models:
The Business model:
class Business extends Eloquent {
//...
public function categories()
{
return $this->belongsToMany('Caregory');
}
}
The Category model:
class Category extends Eloquent {
//...
public function businesses()
{
return $this->belongsToMany('Business');
}
}
The Eloquent query (You already have a pivot table):
$businesses = Business::with(array('categories' => function($q) use ($query3, $query4) {
$q->where('categories.name', 'LIKE', '%'. $query3 .'%')
->where('categories.name', 'LIKE', '%'. $query4 .'%');
}))->where('businesses.location', 'like', '%'. $query1 .'%')
->where('businesses.location', 'like', '%'. $query2 .'%')
->get();
To check the result just use dd($businesses); and examine the collection so you'll get the idea about how you can loop them in your view. Basically, $businesses will contain a collection and each $business model in the collection will contain another collection of $categories, so loop could be something like this:
#foreach($businesses as $business)
{{ $business->propertyname }}
#foreach($business->categories as $category)
{{ $category->propertyname }}
#endforeach
#endforeach

Assuming you have Business moel setup, this is exactly the query you wanted, as eager loading suggested by #WereWolf won't do the job here (where clauses on joined tables vs on 2 separate queries):
Business::from('businesses as b')
->join('categorybusiness as cb', 'b.id', '=', 'cb.business_id')
->join('category as c', 'c.id', '=', 'cb.category_id')
->where('b.location', 'like', "%$query1%")
->where('b.location', 'like', "%$query2%")
->where('c.name', 'like', "%$query3%")
->where('c.name', 'like', "%$query4%")
->get(['b.*']);
There is also another way using whereHas method as long as you have belongsToMany relations setup correctly
Business::whereHas('categories', function ($q) use ($query3, $query4) {
$q->where('categories.name', 'like', "%$query3%")
->where('categories.name', 'like', "%$query4%");
})->where('businesses.location', 'like', "%$query1%")
->where('businesses.location', 'like', "%$query2%")
->get();
