Select2 load data from database - CodeIgniter - php

Question

I try to load database data in my Select2 input. (Im working on CI)
Here's my code from the controller : transforms array in echo json
class Ajax extends CI_Controller {
public function __construct(){
parent::__construct();
$this->load->model('client');
}
public function returnClientsAjax(){
echo json_encode($this->client->getClients());
}
}
Model : returning an array of results
function getClients(){
return $this->db->query("SELECT idclient AS id, CONCAT(societe,' [', nom,']') as text FROM du_client WHERE (societe != '' AND nom != '') AND evo2012 >=2 AND type_client != 'Particulier' AND statut_client = 'Demandeur' AND idclient = 6141;")->result_array();
}
My Select2 :
$("#sel_clients").select2({
placeholder: "Search for an Item",
ajax: {
dataType: "json",
url: "http://commexpert.dev.local/ajax/returnclientsajax",
results: function (data) {
return {results: data};
}
}
});
The input still empty so, don't know what to do.
Thnaks :D

I think something is missing on your data results method. Here is my code from working ajax select2 component:
results: function (data) {
var results = [];
var id1 = data.id;
var name = data.text;
$.each(data.data, function(index, item){
results.push({
id: item[id1],
text: item[name].trim()+' : '+ item[id1]
});
});
return {results: results};
}
also, I'm having somewhat diff data call also:
data: function (term) {
try {
mirko = $(this).closest('[rendered]').find( "input[fparamname$=" + $(this).attr('flookupfiltref') + "]" ).val();
if (mirko.indexOf(' : ') >=0 ) { // pocetna vrijednost
mirko = mirko.split(' : ')[1].trim();
}
} catch(e){
mirko = '';
}
return {
sp_name: $(this).attr('objectname'),
fl_name: $(this).attr('fparamname'),
node_id: $(this).attr('node_id'),
bound: mirko,
q: term,
};
},
I'm having somekind of manipulation before sending or returning q to server,, but I hope that can help you for your service :)
