JSON - Returning JSON to a input jqGrid autocomplete -

i need in thing: i'm doing autocomplete in jqgrid, , need return json input of autocomplete. i'm doing this, in autocomplete return 1 value , in database have more one. me in this. i'm doing return this:

... header("content-type: application/json"); $i=0; while($row = pg_fetch_array($result)) {    $response->input['value']=$row[ac_fin_g];    $i++; } echo json_encode($response); ... 

but example.. have in database values ac_fin_g: {house, home, cake}. if write letter "o", correct appear "house" , "home" in autocomplete, not happening. when change code above code (for input="ho"):

... header("content-type: application/json"); $i=0; while($row = pg_fetch_array($result)) {    $response->input[$i]['value']=$row[ac_fin_g];    $i++; } echo json_encode($response); ... 

i have correct json:

{"input":[{"value":"home      "},{"value":"house     "}]} 

i'm sorry don't know how fix this. me?

update: @oleg figured out how this. case is:

$i=0; while($row = pg_fetch_array($result)) { $response[] = $row[ac_fin_g]; $i++; } echo json_encode($response); 

:)

ps: link can useful :)

the server should create json data expect jquery ui. corresponds jquery ui autocomplete documentation json data should be

["home", "house"] 

or

[{"label": "home", "value": "home"}, {"label": "house", "value": "house"}] 

instead of

{"input":[{"value":"home      "},{"value":"house     "}]} 

which generate. there way decode other json data on client side, it's better follow jquery ui autocomplete standard format.
