嘿guyx我正在尝试在codeingniter中上传图像,但它一直给我一个这样的错误
A PHP Error was encountered
Severity: Notice
Message: Undefined index: pic
Filename: controllers/dou.php
Line Number: 7
我的上传视图
<!DOCTYPE html>
<html>
<head>
<title>Upload form</title>
</head>
<body>
<?php echo form_open('dou/upload');?>
<?php echo form_upload('pic'); ?>
<?php echo form_submit('submit','Save');?>
<?php echo form_close();?>
</body>
</html>
我的控制器
<?php
class DoU extends XM_Controller {
public function index(){
$this->load->view('upload_view1',array('error' => ''));
}
public function upload(){
if(is_uploaded_file($_FILES['pic']['tem_nam'])) {
move_uploaded_file($_FILES['pic']['tem_nam'], './assets'.$_FILES['pic']['name']);
}
}
}
任何帮助将不胜感激..
我已经尝试打印数组“$ _FILES”,但它完全是空的 我做错了什么?
答案 0 :(得分:1)
您应该使用:
form_open_multipart()
功能,因为你有文件上传。
