return $error;
} else {
$updata =$this->upload->data();
$data = $updata['raw_name'].$updata['file_ext'];

}
public function index() {
$this->load->model('blog');
if(isset($_POST['post']) && (!empty($_POST['post']) || strlen($_FILES['inputUpProfile']['name']) > 0) ){

if you got error like
如果你有这样的错误
Array ( [error] =>
The filetype you are attempting to upload is not allowed.
)
in the controller you can do like
在控制器中你可以这样做
if (!$this->upload->do_upload($field)) {
$error = array('error' => $this->upload->display_errors());
$this->session->set_flashdata('error',$error['error']);
redirect('your_function_which_loads_the_view','refresh');
}
and in the view page do something like
并在视图页面中执行类似操作
if($this->session->flashdata('error')){echo $this->session->flashdata('error');}
please let me know if you face any problem.
如果您遇到任何问题，请告诉我。

just display the error in your view, here the steps: first load session library, do it at folder config, file aoutoload.php
只需在您的视图中显示错误，步骤如下：首先加载会话库，在文件夹 config 中执行，文件 aoutoload.php
$autoload['libraries'] = array('session');
in the controller as you have, change this piece of code for this
在您拥有的控制器中，为此更改这段代码
if (!$this->upload->do_upload($field)) {
$this->session->set_flashdata( 'error_msg', $this->upload->display_errors() );
redirect( base_url( 'your view' ) );
}
in your view file...
在您的视图文件中...
<?php
if ( $this->session->flashdata( 'error_msg' ) ) {
echo $this->session->flashdata('error_msg');
}
?>

$pic = $this->do_upload('inputUpProfile');
$this->data['upload_error'] = $pic['error'];
Then in the view:
然后在视图中：
echo $upload_error;
