autocomplete dos not show result passing custom values - php

Question

i'm trying to pass custom values to autocomplete, so:
my custom work value's its based in this question
using a default source like doc's:
$("#inpPesqCli").autocomplete({
source: "ajax/search.php",
minLength: 2,
autoFocus: true
});
firebug returns this (example):
[...
{ "id": "29083", "label": "SOME ONE 2", "value": "SOMEONE WITH LELE" },
{ "id": "19905", "label": "SOME ONE", "value": "SOMEONE WITH LALA"},
...]
work's perfect, results shows up.
when i try to set some custom values:
$("#inpPesqCli").autocomplete({
source: function( request, response ) {
$.ajax({
url: "ajax/search.php",
dataType: "jsonp",
data: {
featureClass: "P",
style: "full",
maxRows: 12,
name_startsWith: request.term
},
success: function( data ) {
response( $.map( data.geonames, function( item ) {
return {
label: item.name + (item.adminName1 ? ", " + item.adminName1 : "") + ", " + item.countryName,
value: item.name
}
}));
}
});
},
minLength: 2,
autoFocus: true
});
firebug return's me the exactly same array result:
[...
{ "id": "29083", "label": "SOME ONE 2", "value": "SOMEONE WITH LELE" },
{ "id": "19905", "label": "SOME ONE", "value": "SOMEONE WITH LALA"},
...]
but, the problem is, when i pass custom calues, the result's dosent shows up.
php:
$type = "C";
$q = strtolower($_GET["name_startsWith"]); // this i change: custom = name_startsWith / default = term
if (!$q) return;
$res = $p->SomeClass($codemp,$q,$type);
$items = array();
while(!$res->EOF){
$items[$res->fields["NOMCLI"]] = $res->fields["CODCLI"];
$res->MoveNext();
}
// below this, i have the php autocomplete default function, if u need, ask then i post.
dont know what i'm missing.

Answer 1

set ajax type = GET , maybe work, by default data send type is POST
$("#inpPesqCli").autocomplete({
source: function( request, response ) {
$.ajax({
url: "ajax/search.php",
dataType: "jsonp",
type : "GET",
data: {
featureClass: "P",
style: "full",
maxRows: 12,
name_startsWith: request.term
},
success: function( data ) {
response( $.map( data.geonames, function( item ) {
return {
label: item.name + (item.adminName1 ? ", " + item.adminName1 : "") + ", " + item.countryName,
value: item.name
}
}));
}
});
},
minLength: 2,
autoFocus: true
});
