Dear fellow codeigniter development
I am a new user of ci4. And I'm sorry if my question sounds stupid. I am trying to make a query select statement. And I found that there is an error Failed to parse json string, error: "Type is not supported". I don't know what this error is. And I also don't know how to debug this error.
This is the error and my controller plus with my vue.js function which is call the controller
Code:
<br />
<b>Fatal error</b>: Uncaught CodeIgniter\Format\Exceptions\FormatException: Failed to parse json string, error: "Type is not supported". in C:\ci4_project\paygate\vendor\codeigniter4\framework\system\Format\JSONFormatter.php:41

This is my controller
PHP Code:
public function search(){
$this->db = \Config\Database::connect();
$user_id = $this->request->getPOST('search');
if($user_id){
$sql = "SELECT pay_daftarid.di_id, pay_daftarid.di_nama, pay_daftarid.di_nokp, pay_daftarid.di_telefon, pay_daftarid.di_emel,
pay_daftarid.di_alamat1, pay_daftarid.di_poskod,pay_daftarid.di_kod_bandar, pay_daftarid.di_kod_negeri,
pay_daftarid.di_kod_negara,
hrp_ruj_negara.keterangan as negara,
hrp_ruj_negeri.keterangan as negeri,
hrp_ruj_bandar.nama_bandar
FROM pay_daftarid
JOIN hrp_ruj_negara ON hrp_ruj_negara.kod = di_kod_negara
JOIN hrp_ruj_negeri ON hrp_ruj_negeri.kod = di_kod_negeri
JOIN hrp_ruj_bandar ON kod_bandar = di_kod_bandar
WHERE pay_daftarid.di_nokp = '$user_id'";
$data = $this->db->query($sql);
return $this->respond($data);
}
}
my vue.js function which is call the controller
Code:
get_id(){
var self = this;
$.post(base_url + '/api/seminar/search', {
search: self.search, //self.search ( data yang nk disearch)
}, function(res){ //res adalah daripada API
self.selected = res.data[0];
console.log(self.contents[0].di_nama);
// console.log(res);//nk tgk apa yg server respond
});
},
I really need help with this issue because I don't know how to fix it. I really appreciate for your time and energy. Thank you.
