Laravel replace property with another if it is 0 - php

Question

I have two columns, price and offer_price.
When I call $products->price, I would like it to bring back the offer_price if it is above 0, if not, return the price.
My modal:
class Product extends Eloquent {
protected $table = 'products';
public function type() {
return $this->hasOne('ProductTypes', 'id', 'type_id');
}
public function brand()
{
return $this->hasOne('ProductBrands', 'id', 'brand_id');
}
public function image() {
return $this->hasMany('ProductImages');
}
public function toArray() {
$ar = $this->attributes;
$ar['type'] = $this->type;
$ar['brand'] = $this->spec_brand;
$ar['price'] = $this->price;
return $ar;
}
public function getSpecBrandAttribute() {
$brand = $this->brand()->first();
return (isset($brand->brand) ? $brand->brand : '');
}
public function getPriceAttribute() {
$price = $this->price;
return (isset($price->price) ? $price->price : '');
}
}
I'm trying to use it here:
$brands = array();
$prices = array();
$out = '';
foreach ($products as $product) {
$brands[$product->brand->id] = $product->brand->brand;
$prices[] = $product->price;
}

Answer 1

You're on the right track. You can find your data in the $attributes array member of your model, rather than distinct member variables in your model.
How about:
public function getPriceAttribute()
{
$which = (0 < $this->attributes['offer_price'] ? 'offer_price' : 'price');
return $this->attributes[$which];
}
Though I would recommend a name other than 'price', unless you completely want to mask 'price' from the usual Laravel interaction. Perhaps $modal->best_price?
