php - Select2 - Ajax Data - Populate The Dropdown based on query -


i'm using select2 populate dropdown of uk towns. uk towns db huge figured ajax call best way bring in data.

i have built post function , php (in codeigniter) catch query , parse it.

i can see data being posted , responded, select2 not populating data.

my jquery :

 $("#areas").select2(     {         tags: [],         ajax: {             url: '/profile/get-towns',             datatype: 'json',             type: "post",             quietmillis: 100,             data: function (term) {                 return {                     query: term                 };             },             results: function (data) {                 return {                     results: data.town_id                 }             },             cache: true         },         escapemarkup: function (markup) { return markup; }, // let our custom formatter work         minimuminputlength: 4,         placeholder         : "start typing town / city",         maximumselectionsize: 2     } );

my response json (example) follows :

[{"town_id":"16994","town":"hartle"},{"town_id":"16995","town":"hartlebury"},{"town_id":"16996","town" :"hartlebury"},{"town_id":"16997","town":"hartlebury common"},{"town_id":"16998","town":"hartlepool" },{"town_id":"16999","town":"hartley"},{"town_id":"17000","town":"hartley"},{"town_id":"17001","town" :"hartley"},{"town_id":"17002","town":"hartley"},{"town_id":"17003","town":"hartley green"},{"town_id" :"17004","town":"hartley green"},{"town_id":"17005","town":"hartley mauditt"},{"town_id":"17006","town" :"hartley wespall"},{"town_id":"17007","town":"hartley wintney"},{"town_id":"27051","town":"new hartley" },{"town_id":"35891","town":"stowe-by-chartley"}]

where going wrong? ideally select dropdown have select value = town_id , select option town name.

thank you.

in select2 configuration:

results: function (data) {     var res = [];     for(var  = 0 ; < data.length; i++) {         res.push({id:data[i].town_id, text:data[i].town});     }     return {         results: res     } },

becasue select2 wants results array of object keys id , text.

otherwise returns formed object

[    {"id":"16994","text":"hartle"},    {"id":"16995","text":"hartlebury"},    {"id":"16996","text":"hartlebury"},    {"id":"16997","text":"hartlebury common"} ]

then

results: function (data) {     return {         results: data     } },
