PHP:未识别索引：productOptionValue

该索引已存在。 不知道我做错了什么

foreach($optionValue['productOptionValue'] as $value): // error here

endforeach;

请帮忙

据我所知，您有一个属性为“optionValues”的对象。假设初始变量名为“$sexy”：

因此，以下几点应该可以做到：

$sexy = Array
(
[optionValues] => Array
    (
        [34] => Array
            (
                [id_product_option] => 1
                [option_value] => Hello
                [required] => 1
                [productOptionValue] => Array
                    (
                        [0] => Array
                            (
                                [id_product_option_value] => 1
                                [id_option_value] => 88
                                [quantity] => 12
                                [subtract] => 1
                                [price] => 232.0000
                                [price_prefix] => r
                                [weight] => 23.00000000
                                [weight_prefix] => k
                            )

                    )

            )

它应该是

$optionValue[34]['productOptionValue']

试试这个

foreach（$optionValue[34]['productOptionValue']作为$value）{}

$sexy = Array
(
[optionValues] => Array
    (
        [34] => Array
            (
                [id_product_option] => 1
                [option_value] => Hello
                [required] => 1
                [productOptionValue] => Array
                    (
                        [0] => Array
                            (
                                [id_product_option_value] => 1
                                [id_option_value] => 88
                                [quantity] => 12
                                [subtract] => 1
                                [price] => 232.0000
                                [price_prefix] => r
                                [weight] => 23.00000000
                                [weight_prefix] => k
                            )

                    )

            )

foreach($sexy['optionValues'][34]['productOptionValue'] as $value):
    // I should be nice now and not throw an error here
endforeach;
