如何在查询字符串中将多维数组从JavaScript发送到PHP

Question

I am using following code:

window.location.assign("index.php?module=pengu_dispatch&action=cover_letter&value="+list);

Here I want to send multidimensional array in query string to the PHP file.

Using JSON stringify function I converted array into string and send, but on PHP side after decoding I am not getting the complete array.

Please let me know what I could be doing wrong

You can put json in a GET param by url encoding it.

url = 'http://whatever/some.php?param='+encodeURIComponent(JSON.stringify(list))

And then in php read it like this

$list = json_decode($_GET['param']);

Be careful about the size of your list because URL's have a size limit of about 1~2kb. If you want to send a large amount of data you have to use POST.
