anyone can help?..

toeknee•5mo ago

Your code blocks should start with 3 x ` and then php so it formats it in php code block. You need to explain more what you want. I am not following your issue.

Dennis Koch•5mo ago

@gigiloouu For the next time: Please don't open mutilple threads for the same issue. I think you can use the mutateDataBeforeSave hook on the form to manually validate the data and throw a Validation Exception. That's probably the only way

gigiloouu•5mo ago

sorry, i just wanted to write my problem more detail okay thanks i will try.. u mean use mutateFormDataBeforeCreate becouse i cant find any function or article about mutateDataBeforeSave

Dennis Koch•5mo ago

Yes

gigiloouu•5mo ago

i read this already and when i wrote this function its not working. like i try to just dd(); data but not working i mean im getting data but i dont have brands data

gigiloouu•5mo ago

im using pivot table for brands

toeknee•5mo ago

ahh it won't work, ennis is slightly wrong as it's relationship data it's kept out of it, I think you need a different method.

gigiloouu•5mo ago

hm for another task i just use maxValue and next i wrote some logic to see max value what will be but at this moment I have no idea how many brands will be becouse u can add as many as u wish can u give me some idea or hint what will be good for this issue 😢

toeknee•5mo ago

So what is the overall goal you are trying to achieve?

gigiloouu•5mo ago

okay i will tell u

toeknee•5mo ago

Please try to write as clear as possible.

gigiloouu•5mo ago

I have purchase table where i have Sum Amount

gigiloouu•5mo ago

also purchase have brands, becouse of brands is many to many i use pivot table

gigiloouu•5mo ago

u can click add blog and its add new feal for new brand all brands has their own amount so all this brands amount should be equal of this sum amount like if brands amount is more then sum amount we should have a error if its less should be error it should be equal

toeknee•5mo ago

Where is sum amount entered? Earlier in the form?

gigiloouu•5mo ago

brands amount sum should be equal of sum amount

gigiloouu•5mo ago

form looks like this i can make sum amount earlier its not a problem

toeknee•5mo ago

So use a custom validation rule?

->rules([
    fn (Get $get): Closure => function (string $attribute, $value, Closure $fail) use ($get) {
        
        $max = 0;
        $current = 0;
        $brands = $get('../purchaseBrands', []);
        
        foreach($brands as $brand) {
          $current += $brand['amount'];
        }

        if( $max !== $current ) {
           $fail("The sum is ' . $max . ' and the current is ' . $current' . ' Please ensure the sum is the same as all brands counted.");
        }
    },
])

->rules([
    fn (Get $get): Closure => function (string $attribute, $value, Closure $fail) use ($get) {
        
        $max = 0;
        $current = 0;
        $brands = $get('../purchaseBrands', []);
        
        foreach($brands as $brand) {
          $current += $brand['amount'];
        }

        if( $max !== $current ) {
           $fail("The sum is ' . $max . ' and the current is ' . $current' . ' Please ensure the sum is the same as all brands counted.");
        }
    },
])

Or similar to that.

git it a try, it's just a rough free hand code up from memory. But gives you the runderstanding. see: https://filamentphp.com/docs/3.x/forms/validation#custom-rules for the docs
