Question

getlocal是一种数据库查询功能，但是即使我在名为local的表中插入数据，该函数也无法返回null以外的值

class denuncia_model extends CI_Model {
function __construct(){
    parent::__construct();

}
public function insertlocal($local){
    $insertquery = "INSERT INTO local(estado,lng,lat) VALUES (?,?,?)";
    $this->db->query($insertquery,$local);
}
public function getlocal($local){
    $queryteste = "SELECT * FROM local WHERE estado = ? AND lng = ? AND lat = ?";
    $query = $this->db->query($queryteste,$local);
    $row = $query->row_array();
    $id = $row['id'];
    return $id;

}
public function insertdenuncia($denuncia){
    $insertdenunciaquery = "INSERT INTO denuncias(descricao,data,forma,genero,preconceito,idade,id_local) VALUES (?,?,?,?,?,?,?)";
    $this->db->query($insertdenunciaquery,$denuncia);

}

文件denuncia_controller

        $local = array($estado,$lng,$lat);
        $denuncia = array($descricao,$data,$agressao,$gender,$preconceito,$age);
        $this->denuncia_model->insertlocal($local);
        $id = $this->denuncia_model->getlocal($local);
        array_push($denuncia,$id);
        $this->denuncia_model->insertdenuncia($denuncia,$local);

Answer 1

class denuncia_model extends CI_Model {
function __construct(){
    parent::__construct();

}
public function insertlocal($local){
    $insertquery = "INSERT INTO local(estado,lng,lat) VALUES (?,?,?)";
    $this->db->query($insertquery,$local);
    return $this->db->insert_id();
}

Answer 2

您应该在函数末尾将return语句与insert_id（）一起使用

return $this->db->insert_id();

Codeigniter-函数始终返回null
