Question

I have such select list in html:

<input type="checkbox" name="drive_style" value=1 checked />123<br />
<input type="checkbox" name="drive_style" value=2 />123<br />
<input type="checkbox" name="drive_style" value=3 checked /> 123<br />
<input type="checkbox" name="drive_style" value=4 />123<br />
<input type="checkbox" name="drive_style" value=5 checked />123<br />

I have to send values(1, 3, …) of checked boxes to the php script (I’m using ajax with jquery) like an array. Something like: drive_style[index].

    $.post('post_reply.php', {'drive_style'  : $('drive_style')}, function(data){
        alert(data);
    });

In PHP script:

print_r($_POST['drive_style']);

[object Object]

upd:
My new code:

<input type="checkbox" name="drive_style[]" value=1 checked />123<br />
<input type="checkbox" name="drive_style[]" value=2 />123<br />
<input type="checkbox" name="drive_style[]" value=3 checked />123<br />
<input type="checkbox" name="drive_style[]" value=4 />123<br />
<input type="checkbox" name="drive_style[]" value=5 checked />123<br />

    $.post('post_reply.php', {'drive_style':$('input[name=drive_style]').serialize()}, function(data){
        alert(data);
    });

It alerts empty string.

Answer 1

​$(function() {
var serial = $('input[name=drive_style]').serialize();
//php -> $('input[name=drive_style[]]').serialize();
  alert( serial );
});​

this give you:

drive_style=1&drive_style=3&drive_style=5

but for work with php you also need to have input name like this:

<input type="checkbox" name="drive_style[]" value=1 checked />123<br />

NOTE: drive_style[]

that obviously giv you:

drive_style[]=1&drive_style[]=3&drive_style[]=5
