What property inside the form can I use to assign this index string [‘size’]

[co.ador]

 

I have this database field that used as the form input value '. $variety['price']. ' I also have a '. $variety['size']. ' database field that carry the name of the product but I don't know what another form input property to use to assign this size database field as a value to the input form property?

 

I feel like I have run out of properties to carry more values to other values beside price to cart.php.

 

Thank you the script is as below.

 

<form action="cart.php" method="post">
foreach($product['varieties'] as $variety){ 
echo'<input style="width:10px; margin-left:9px; " name="price[]" type="checkbox" value="' . $variety['price']. '"  />';
}
</form>

As sizes will be a restricted and know set of values, why not use an array of radio buttons, or a dropdown select list?
