我使用jQuery模式和Ajax为我的表单提交数据和文件，但我不知道如何使用文件上传类在根文件夹中上传我的文件和图像。任何一个告诉我在哪里我必须在我的代码中添加带有ajax的上传功能。我真的需要这个。我已经完成了这些更改。
下面我附上了我的模态代码和查看代码供你参考：
型号代码：
function __construct()
{
// Call the Model constructor
parent::__construct();
$this->load->database();
}
public function getAll(){
$this->db->select('*');
$this->db->from('emp');
$this->db->limit(50);
$this->db->order_by('id','ASC');
$query = $this->db->get();
return $query->result();
}
public function get($id){
$query = $this->db->get_where('emp',array('id'=>$id));
return $query->row_array();
}
public function save(){
$config['upload_path'] = './uploads/';
$config['overwrite'] = TRUE;
$config['allowed_types'] = 'gif|jpg|png|jpeg|pdf|txt|sql';
$config['max_size'] = 8048000;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
if ( $this->upload->save('userfile')) {
$data = array('upload_data' => $this->upload->data());
$Firstname = $this->input->post('Firstname');
$Lastname = $this->input->post('Lastname');
$Email = $this->input->post('Email');
$Phone = $this->input->post('Phone');
$Address = $this->input->post('Address');
$Password = $this->input->post('Password');
$Status = $this->input->post('Status');
$Createddate = $this->input->post('Createddate');
$Updateddate = $this->input->post('Updateddate');
$File = $data['upload_data']['file_name'];
// print_r($File);
// die;
$data = array(
'Firstname' => $Firstname,
'Lastname' => $Lastname,
'Email' => $Email,
'Phone' => $Phone,
'Address' => $Address,
'Password' => $Password,
'Status' => $Status,
'Createddate' => $Createddate,
'Updateddate' => $Updateddate,
'File' => $File
);
// print_r($data);die;
$this->db->insert('emp',$data);
}
}
public function update(){
$id = $this->input->post('id');
$Firstname = $this->input->post('Firstname');
$Lastname = $this->input->post('Lastname');
$Email = $this->input->post('Email');
$Phone = $this->input->post('Phone');
$Address = $this->input->post('Address');
$Password = $this->input->post('Password');
$Status = $this->input->post('Status');
$Createddate = $this->input->post('Createddate');
$Updateddate = $this->input->post('Updateddate');
$File = $this->input->post('File');
$data = array(
'Firstname' => $Firstname,
'Lastname' => $Lastname,
'Email' => $Email,
'Phone' => $Phone,
'Address' => $Address,
'Password' => $Password,
'Status' => $Status,
'Createddate' => $Createddate,
'Updateddate' => $Updateddate,
'File' => $File
);
$this->db->where('id',$id);
$this->db->update('emp',$data);
}
}
?>

upload image using codeigniter with ajax and formdata
在表格属性中使用enctype =“multipart / form-data”。你没有按照我的说法宣布表格。
