array Fatal error: Unsupported operand types

[mrooks1984]

hello, i am trying to get my array result to keep adding up the result into the $option_price varible, but i am getting this message:

 

Fatal error: Unsupported operand types on line 209

 

so put that part of the code on here to see if someone can help.

 

$option_price = '0.00';
		foreach ($product_option_prices as $product_option_price) {
			$option_price .= $option_price + $product_option_price['option_price'];
		}

 

thanks all

what line on your code is this?

 

 

$option_price = '0.00';

foreach ($product_option_prices as $product_option_price) {

$option_price .= $option_price + $product_option_price['option_price'];

}

this one is 209:

 

$option_price .= $option_price + $product_option_price['option_price'];

 

thanks.

What does this give you?

$option_price = 0;
foreach ($product_option_prices as $product_option_price) {
   $option_price += $product_option_price['option_price'];
}

 

You could even type cast to (float).

thanks for your reply, still the same.

concatenation is for strings. the code jcbones gave you should at least have changed the fatal error.  you'll need to supply more information than "still the same"

What is the structure of $product_option_prices?

 

echo '<pre>';
print_r($product_option_prices);
echo '</pre>';

[mrooks1984]

hi, Array ( [option_price] => Array ( [1] => 5.00 [2] => 0.00 ) ) )

[Pikachu2000]

$product_option_prices['option_price'] is another array. That is why you're getting the unsupported operand type error; you're attempting to do 4.125 + array. You can see why that won't work, yes?

hi, i this is how i am getting the information into the array

 

		//get option prices
		foreach($_POST['option_price'] as $key => $value){
			if($value !=''){	
				$product_option_prices[] = array("option_price" => $_POST['option_price']);
			}
		}

and this is the price bit again

 

this is the full print out: Array ( [option_value] => Array ( [1] => Black [2] => Bacon ) ) Array ( [0] => Array ( [option_price] => Array ( [1] => 5.00 [2] => 0.00 ) ) [1] => Array ( [option_price] => Array ( [1] => 5.00 [2] => 0.00 ) ) ) 0

		$option_price = 0;
		if (isset($product_option_values)) {
		foreach ($product_option_values as $product_option_value);
		foreach ($product_option_prices as $product_option_price) {
			//$option_price += $product_option_price['option_price'];
		}
		print_r($product_option_value);
		print_r($product_option_prices);

		}

i thought this is how i call that array  $product_option_price['option_price'];?

[mrooks1984]

sorted it now, thanks anyway guys

[mrooks1984]

hello, hoping someone can help i am stuck on the last bit.

 

		if (isset($product_option_values)) {
		foreach ($store_variations_values as $store_variation_values) {
		foreach ($product_option_values as $product_option_value) {
			if($product_option_value == $store_variation_values['title']) {
				$option_value_price += $store_variation_values['price'];
			}
			}	
		}

 

the code above doesent seem to be working i am getting no errors but its not adding it up the if($product_option_value == $store_variation_values['title']) is supposed to compare the option value and get the price for that item from the array, its working it out as 0 and should be 23 including the second value of the loop (1 is 22 and the other is 1) hoping someone could point out were i have gone wrong.

have you tried using array_diff instead
