I have products table that has 2 columns price_before | price_after
In the view I loop through all products
@foreach($products as $product)
{{$product->price_before}}
{{$product->price_after}}
@endforeach
I would like to get the percentage and achieve an equation like
(1 - New Price / Old Price)*100)
so that it looks 50% or at least 50 .. not like 50.1234223
my ProductsController.php
public function index(){
$products = Product::orderBy('created_at','desc')->paginate(39);
return view('products', ['products' => $products]);
}
How can I achieve that in the productscontroller ?
you may use rounding method https://www.w3schools.com/php/func_math_round.asp
or number formatting https://www.php.net/manual/en/function.number-format.php
it may more convenience to create as a method in the model class or have a dedicated class if you need to call this repeatedly
Definitely look up the math functions in the PHP manual, all sorts of functions there you may need.
Using a framework such as laravel goes hand-in-hand with using PHP functions as needed.
@siangboon and @jlrdw .. Hello guys thank you so much for the head up .. actually I dove into the php manual and it's soo interesting .. so many things to learn :D so thanks..
{{(ceil(($product->price_before - $product->price_after)/$product->price_before*100))}}
Now I did that in the blade view and it gave me the expected result I'm looking for .. actually this percentage thing is jut serving informing purpose .. nothing more.
I really think there is a better way I can get this into the controller and just call something like "$discount" in the blade view .. @siangboon can you please give me more input on how can I improve this by moving it to a dedicated class .. or even in the Product Model :)
if you think it is related to your model, then just create a function and put your calculation works in that model and return the result.. so next time you can simply call $product->discount()
but if you think this is applicable to multiple models then you can consider use trait or global helper function... ,
Add an accessor to the Product model
public function getDiscountAttribute()
{
return ceil(($this->price_before - $this->price_after)/$this->price_before *100))
}
//usage
{{$product->discount}}
this is exactly what I was looking for .. Thank you guys @sinnbeck @jlrdw and @siangboon <3
