用ci上传图片，显示的内容为空
就是用ci上传的图片，在控制器 查看$this->upload->data();时，不显示图片的相关信息，只显示：麻烦大家帮忙看一下，谢谢了array'file_name' => string '' (length=0)'file_type' => string '' (length=0)'file_path' => string './upload/' (length=9)'full_path' => string './upload/' (length=9)'raw_name' => string '' (length=0)'orig_name' => string '' (length=0)'client_name' => string '' (length=0)'file_ext' => string '' (length=0)'file_size' => string '' (length=0)'is_image' => boolean false'image_width' => string '' (length=0)'image_height' => string '' (length=0)'image_type' => string '' (length=0)'image_size_str' => string '' (length=0)
这是我的控制器部分：
public function main(){
$data['userinfo'] = $this->user_info;
//接收上传的logo
if($this->input->post()){
$config['upload_path'] = './upload/'; //这个路径很重要
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1024';
$config['max_width']= '1024';
$config['max_height']= '768';
$this->load->library('upload', $config);
$this->upload->do_upload();
var_dump($this->upload->data());die; //问题是，打印出来的内容为空，不能显示图片的相关信息
}
$this->_template('user/uploadlogo',$data);
}
我的视图部分：
<form action="" method="post" enctype="multipart/form-data" name="form1">
<input name="upload" type="file" style="width:200;border:1 solid #9a9999; font-size:9pt; background-color:#ffffff" size="17">
<input type="submit" name="uploadimg" value="上 传 " style="width:42;border:1 solid #9a9999; font-size:9pt; background-color:#ffffff" size="17">
</form>
