PHP从post数组中获取值

Question

I'm posting an array from a html form with the following input-tag:

<input type="text" name="new_service[1]['category']">

I get this array:

Array
(
    [1] => Array
        (
            ['category'] => 1
            ['description'] => asdasd
            ['price'] => asdasd
            ['time'] => 1
        )

)

When I try to get the category value with

echo $_POST['new_service'][1]['category']; 

I get this error message:

Notice: Undefined index: category

What am I doing wrong?

Answer 1

The index you create this way is not category but 'category' i.e. you create an index that also has single quotes.

So to echo what you want you should use:

echo $_POST['new_service'][1]["'category'"];
