Please help with jquery + ajax request.

I'm trying to send an array with ajax request to php. Can't understand what I am doing wrong. Can someone please help? This is the code:

<script>
$(document).ready(function(){

var array = $.makeArray(2);

var url = window.location.pathname;
var filename = url.match(/.*\/(.*)$/)[1];

var arr = $.toJSON(array);

var a = "list=" + arr;


$.ajax({
url: filename,
context: a,
success: function(){alert(a);}

});

});
</script>

<?php

$list = json_decode($_POST['list']);

var_dump($list);
?>

It says Undefined index: list.

 

I haven't tried running your code, but try

$.ajax({
    url: filename,
    data: "arr=a",
    success: function(){alert(a);
}
    
});

Code (markup):

BTW, the default is a GET. If you want POST data, add
type: "POST",
in the argument list. (Order doesn't matter, but the last item - success, in your case - doesn't end in a comma.)

 

Thanks mate the type: "POST" helped . Topic closed, everything works .

 

var str='var1[]='+value1+'&var1[]='+value2;
$.ajax({
url:filename.php,
data:str,
method:'POST',
success:function(msg)
{
alert(msg);
}


});
