When you're using relationship() with a Select you should use the third parameter on that method to alter the query, not options() https://filamentphp.com/docs/3.x/forms/fields/select#customizing-the-relationship-query

thanks 🙏

You'll also want to make the supplier_id Select live, so that you can update that query whenever it changes.

Select::make('brand_id')
    ->relationship('brand', 'name', function (Builder $query, Get $get) {
         $brandIds = explode(',', Supplier::find($get('supplier_id'))->brand_id)
         $query->whereIn('id', $brandIds)
    })
    ->hidden(fn (Get $get) => $get('supplier_id') === null),

    ->label('Brand')

oh thanks bro ❤️

Tetracyclic•4mo ago

You probably want something like that, you'll need to use explode() to split your string of IDs up. It might make more sense to do that on the Supplier model itself, or better yet, model the Supplier > Brand relationship as a many-to-many, rather than using a string of IDs.

gigiloouu•4mo ago

can u show me Builder import?

Tetracyclic•4mo ago

It would be Illuminate\Database\Eloquent\Builder, but you could find that out by running the code and seeing what fails. 😉 This is all in the docs.

gigiloouu•4mo ago

i know im trying to do this about 2 hours but now i have error

                        $brandIds = explode(',', Supplier::find($get('supplier_id'))->brand_id);

                        $brandIds = explode(',', Supplier::find($get('supplier_id'))->brand_id);

Attempt to read property "brand_id" on null i think problem is $get('supplier_id'))->brand_id) there i have not supplier_id in supplier table i have brand_id but main errori s brand_id is null it can read it

Tetracyclic•4mo ago

$get('supplier_id') is retrieving the selected Supplier ID from the first select. You will need to add a check to make sure it's set before doing this.

    ->relationship('brand', 'name', function (Builder $query, Get $get) {
         if($get('supplier_id') === null) {
             return;
         }

         $brandIds = explode(',', Supplier::find($get('supplier_id'))->brand_id)
         $query->whereIn('id', $brandIds)
    })

    ->relationship('brand', 'name', function (Builder $query, Get $get) {
         if($get('supplier_id') === null) {
             return;
         }

         $brandIds = explode(',', Supplier::find($get('supplier_id'))->brand_id)
         $query->whereIn('id', $brandIds)
    })

gigiloouu•4mo ago

now problem only is when i select supplier and click brand i have this err explode(): Argument #2 ($string) must be of type string, array given in there $brandIds = explode(',', Supplier::find($get('supplier_id'))->brand_id); we use explode right so why..

Tetracyclic•4mo ago

Do you have an attribute that is casting brand_id to an array? If so you shouldn't need explode() there, but you said it was a string above.

gigiloouu•4mo ago

yes in supplier model i have this code public function brandId(): Attribute { return Attribute::make( get: fn($value) => explode(',', $value), set: fn($value) => implode(',', $value), ); } public function subbrandId(): Attribute { return Attribute::make( get: fn($value) => explode(',', $value), set: fn($value) => implode(',', $value), ); } aa its works finallly thanks u soo much ❤️ i take a look code and again thanks ❤️ 😄
