Passing multi dimensional array to PHP with jQuery and AJAX -


i've got jquery code:

$(document).ready(function() {  answers = new array();  answers[0] = new array(); answers[0]['question_id'] = 12; answers[0]['answer_id'] = 32;  answers[1] = new array(); answers[1]['question_id'] = 55; answers[1]['answer_id'] = 132;  answers[2] = new array(); answers[2]['question_id'] = 987; answers[2]['answer_id'] = 1112;  $.ajax({     type: "post",     url: "collect.php",     data: {answers: answers},     datatype: "json",     beforesend:function(){         // before sending request server     },     error: function(jqxhr, textstatus, errorthrown){          alert(errorthrown);     },     success: function(data){          alert('success!');     } });

});

now, should work? according i've found when looking code examples should. problem is, have no idea how collect data in php file. mean, it's $_post[], what? how collect $result[0]['question_id'] , other data?

thanks lot in advance,

you're never populating arrays inside of answers array data, length still 0 because you're using string indexes rather int indexes. want objects stored in array.

answers[0] = {}; answers[0]['question_id'] = 12; answers[0]['answer_id'] = 32;
