我有上传图像的视图，我有输入类型的文件，比如：
<input type="file" name="ev_pic" size="20" />
我的控制器像：
if(strlen($_FILES['ev_pic']['name']) > 0)
{
$pic = $this->do_upload('ev_pic');
}
上传方式：
public function do_upload($field) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
if (!$this->upload->do_upload($field)) {
$error = array('error' => $this->upload->display_errors());
return $error;
} else {
/*$data = array('upload_data' => $this->upload->data());
return $data;*/
$updata =$this->upload->data();
$data = $updata['raw_name'].$updata['file_ext'];
return $data;
}
}
在调试中显示此错误：
Severity: Notice
Message: Undefined index: ev_pic
Filename: administrator/events.php
Line Number: 68
Error Number: 1054
Unknown column 'Array' in 'field list'
UPDATE `events` SET `ev_id` = 0, `ev_text` = 0, `ev_pic` = Array
Filename: D:'AppServ'www'd5n'rashaqa2'system'database'DB_driver.php
Line Number: 330
所以我会用ev_pic命名文件，问题在哪里？
在控制器的__construct函数中加载上传库，如下所示：
public function __construct(){
parent::__construct();
$this->load->library('upload');
}
然后将您的功能更改为：
public function do_upload($field) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
/////////// change this //// //////
$this->upload->initialize($config);
///////////////////////////////////
if (!$this->upload->do_upload($field)) {
$error = array('error' => $this->upload->display_errors());
return $error;
} else {
/*$data = array('upload_data' => $this->upload->data());
return $data;*/
$updata =$this->upload->data();
$data = $updata['raw_name'].$updata['file_ext'];
return $data;
}
}
请检查您的表单
form enctype="多部分/表单数据"是否可用
并更改这条线路
if（！$this->upload->do_upload（$field）
