Eloquent Multitable query - php

Question

I trying to create a search function in php with Slim and Eloquent 5.1, but i have a problem to get the results from the database.
This are my tables
Listing Table
id | title | description | price | size |etc...
-----|--------|-------------|-------|--------|-------
1 | list1 | some text | 500 | 50 |
2 | list2 | some text | 700 | 80 |
3 | list3 | some text | 350 | 120 |
Listings Option Table
id | id_listing | opt_name | opt_value
-----|-------------|-------------|----------
1 | 1 | rooms | 3
2 | 1 | baths | 4
3 | 2 | rooms | 8
4 | 3 | baths | 1
5 | 3 | rooms | 6
Listings Images Table
id | id_listing | file_name
-----|-------------|-------------
1 | 1 | file_1.png
2 | 1 | file_2.png
1 | 2 | file_3.png
2 | 3 | file_4.png
Now i found a way to get all the results with all they options with
listado = $app->listing->with(['options'],['imgs'])->get();
My classes
//Listing Class
class Listing extends Eloquent{
protected $table = 'listings';
public function options(){
return $this->hasMany('Casas\Listing\ListingOption', 'id_listing', 'id');
}
public function imgs(){
return $this->hasMany('Casas\Listing\ListingImg', 'id_listing');
}
}
// ListingOption class
class ListingOption extends Eloquent{
protected $table = 'listings_options';
public function listings()
{
return $this->belongsTo('Casas\Listing\Listing', 'id_listing');
}
}
// ListingImg Class
class ListingImg extends Eloquent{
protected $table = 'listings_imgs';
public function listings()
{
return $this->belongsTo('Casas\Listing\Listing', 'id_listing');
}
}
but i cannot find a way to filter the query the way i want to. I tried many thing.
Example: I want to get all the listings that have price less than 600 and have more than 2 rooms.
So that be listing id 1 and 3
If anyone can help create this query i'll appreciate that.

Answer 1

What you want want to use is whereHas.
When accessing the records for a model, you may wish to limit your results based on the existence of a relationship
$result = $app->listing->with('options', 'imgs')
->whereHas('options', function ($query) {
$query->where('opt_value', '>', 2)
->where('opt_name', 'room');
})
->where('price', '<', 600)->get();
So what we are doing here is, eager loading options and imgs tables and fetching only the listings that have at least one option where opt_value is bigger than two and opt_name is room.
You can find more in info about querying relationships in here

Answer 2

I would try something like this:
$result = $app->listing->with(
['options' => function ($query) {
$query->where('opt_value', '>', 2);
}
],
['imgs'])->where('price', '<', 600)->get();
The last, outer where should be assigned to listing. The inner where, passed in a callback, should be assigned to options directly.
Take a look at the docs (the "Constraining Eager Loads" section).
