Question

I am trying to display data for a plugin with a predefined json format, but after I try the data does not match the format how the problem?
JSON Required
[
{
latLng: [-6.17343444,1206.834234294],
name: 'XY'
},
{
latLng: [-6.1742343244,106.898987294],
name: 'XK'
}
]
Result my JSON
[
{
"latLng": "-6.17343444,1206.834234294",
"name": "XK"
},
{
"latLng": "-6.1742343244,106.898987294",
"name": "XY"
}
]
myscript PHP
public function lat_lang() {
foreach($this->model->name_model() as $row){
$data[] = array(
'latLng' => $row->lat_long,
'name' => $row->city
);
}
header('content-type: application/json');
echo json_encode($data);
}
call JSON
$.parseJSON('<?php echo base_url().'mycontrollers';?>', function(datas) {
console.log(datas);
});

You can use explode() to transform the string "-6.17343444,1206.834234294" into an array [-6.17343444,1206.834234294]:
public function lat_lang() {
foreach($this->model->name_model() as $row){
$data[] = array(
'latLng' => explode(',',$row->lat_long),
'name' => $row->city
);
}
header('content-type: application/json');
echo json_encode($data);
}
If you want to get floats (for all value in the JSON), you could use JSON_NUMERIC_CHECK:
json_encode($data, JSON_NUMERIC_CHECK);
Or, just for a specific value:
$latLng = explode(',', $row->lat_long);
$latLng = array_map('floatval', $latLng);
$data[] = array(
'latLng' => $latLng,
'name' => $row->city
);
