Send multidimensional array from JQuery AJAX to PHP
I want to send a multidimensional array to PHP from JQuery AJAX, but it gets to PHP like this
Array
(
[recordid] => 38
[locations] => [object Object],[object Object]
)
I must be making some stupid mistake. here is the code. it gets records from the table and sends to PHP
$(document).on('click','.savenow',function(){
recordid = $(this).data('id');
locations = [];
$('.selectrec').each(function () {
parent = $(this).parent().parent();
name = parent.find('td').eq(5);
address = parent.find('td').eq(6);
lat = parent.find('td').eq(1);
lng = parent.find('td').eq(2);
row = [name,address,lat,lng];
locations.push(row);
});
locations = locations.toString();
$.ajax({
type: "POST",
url:'/record/saveSearchedLocations',
data: { recordid: recordid,locations:locations },
dataType: 'json',
success: function (data) {
console.log(data);
},
error:function(data){
alert("something went wrong, please try again.");
}
});
});
and this is the PHP function where I am getting the data:
function saveSearchedLocations(){
print_r($_POST);
}

Use JSON.stringify()
instead toString()
like this:
Change your AJAX call to the following:
$(document).on('click','.savenow',function(){
recordid = $(this).data('id');
locations = [];
$('.selectrec').each(function () {
parent = $(this).parent().parent();
name = parent.find('td').eq(5);
address = parent.find('td').eq(6);
lat = parent.find('td').eq(1);
lng = parent.find('td').eq(2);
row = [name,address,lat,lng];
locations.push(row);
});
ajaxData = { recordid : recordid,locations : locations }
$.ajax({
type: "POST",
url:'/record/saveSearchedLocations',
data: JSON.stringify(ajaxData),
dataType: 'json',
success: function (data) {
console.log(data);
},
error:function(data){
alert("something went wrong, please try again.");
}
});
});
JSON.stringify()
converts your array to an actual json string, not Array.prototype.toString()
which concatenates your array (one level) using a comma as separator.

Take this answer as a reference:
I think you need to use JSON.stringify(selectedData)
in order to use it on the server.
jQuery:
var obj = { 'risk_cat': risk_cat, 'risk_type': risk_type };
selectedData.push(obj);
$.post('serive.php', { DTO: JSON.stringify(selectedData) },
function(data){ /* handle response, */ });
service.php:
header('Content-type: application/json');
header('Cache-Control: no-cache, must-revalidate');
$foo = json_decode($_POST['DTO']);
$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5); //example data
echo json_encode($arr);
This should get you started. In response, ajax alert(data.a)
will warn "1"

sendAjax = function() {
var data = {
foo: 123,
bar: 456,
rows: [{
column1: 'hello',
column2: 'hola',
column3: 'bonjour',
}, {
column1: 'goodbye',
column2: 'hasta luego',
column3: 'au revoir',
}, ],
test1: {
test2: {
test3: 'baz'
}
}
};
$.ajax({
type: 'post',
cache: false,
url: './ajax/',
data: data
});
}
When the button is clicked, the following structured data is displayed in the PHP $ _POST variable:
Array
(
[foo] => 123[bar] => 456[rows] => Array(
[0] => Array(
[column1] => hello[column2] => hola[column3] => bonjour
)
[1] => Array(
[column1] => goodbye[column2] => hasta luego[column3] => au revoir
)
)
[test1] => Array(
[test2] => Array(
[test3] => baz
)
)
)
This will only work with jQuery 1.4.0+. Otherwise, jQuery simply calls .toString () on the nested array on key "strings" and the nested object on key "test1", and they are passed to PHP with useless values "[object Object
