将jQuery数组传递给PHP（POST）

Question

I want to send an array to PHP (POST method) using jQuery.

This is my code to send a POST request:

 $.post("insert.php", { // Arrays customerID: customer, actionID: action }) 

This is my PHP code to read the POST data:

$variable = $_POST['customerID']; // I know this is vulnerable to SQLi

If I try to read the array passed with $.post , I only get the first element. If I inspect the POST data with Fiddler, I see that the web server answers with "500 status code".

How can I get the complete array in PHP?

Thanks for your help.

To send data from JS to PHP you can use $.ajax :

1/ Use "POST" as type , dataType is what kind of data you want to receive as php response, the url is your php file and in data just send what you want.

JS:

var array = {
                'customerID': customer,
                'actionID'  : action
            };

$.ajax({
    type: "POST",
    dataType: "json",
    url: "insert.php",
    data:
        {
            "data" : array    

        },
    success: function (response) {
        // Do something if it works
    },
    error:    function(x,e,t){
       // Do something if it doesn't works
    }
});

PHP:

<?php

$result['message'] = "";
$result['type']    = "";

$array = $_POST['data']; // your array 

// Now you can use your array in php, for example : $array['customerID'] is equal to 'customer';


// now do what you want with your array and send back some JSON data in your JS if all is ok, for example : 

$result['message'] = "All is ok !";
$result['type']    = "success";

echo json_encode($result);
