JS commit array parameter, background Receive As String problem

First, let's look at a JS method of submitting an array by post:

var image = [' 20180512135343_564.png ', ' 20180512135156_860.png '];

$.post ('/community/community/add_community ', {    ' type ': 1,    ' title ': ' Tupianshangchuan ' ,    ' Image ': Image,    },function(res) {    console.log (res);});

Normally, an image is submitted to the background as an array:

Perhaps when you use some framework, the framework handles some of its own processing so that the data received in the background is in string form, such as "[' 20180512135343_564.png ', ' 20180512135156_860.png ']".

In this case, we can use json.stringify to submit an array of objects to a JSON-form string to avoid this phenomenon in the background. The code is as follows:

JS Code:

var image = [' 20180512135343_564.png ', ' 20180512135156_860.png '];$.post ('/community/community/ Add_community ', {    ' type ': 1,    ' title ': ' Tupianshangchuan ',    ' image ': Json.stringify (image),    },function(res) {    console.log (res);});

PHP Receive,json_decode () function Processing:

$image $_post ("image"); $image _arr = Json_decode ($image,true);
