将多维数组添加到mysql

Question

您好我有多维数组：

Array
(
    [0] => Array
        (
            [name] => uzsakymas
            [value] => title
        )

[1] => Array
    (
        [name] => preke
        [value] => name
    )

[2] => Array
    (
        [name] => kaina
        [value] => 5
    )

[3] => Array
    (
        [name] => kiekis
        [value] => 1
    )

[4] => Array
    (
        [name] => preke
        [value] => name2
    )

[5] => Array
    (
        [name] => kaina
        [value] => 5
    )

[6] => Array
    (
        [name] => kiekis
        [value] => 5
    )

)

但是当我尝试获取添加到mysql的值时，我收到了一个错误。我做错了什么？

$json = json_decode($_POST['json'], true);
print_r($json);
foreach($json as $key => $name) {
    echo $name['preke'];
}

  

未定义的索引：preke in ...

Answer 1

回应$name['preke'];不会让你走得太远。请尝试$name['name'];，因为name是关键。

Answer 2

尝试：

$name['name'];

你的$ name var是包含2个关联条目的数组：name，value;
