文件上传代码点火器..不起作用 [英] file upload code igniter..not working

问题描述

这在我的文件上传控制器中

This is in my controller for file upload

$config['upload_path'] = './assets/images/b2b/banner-agent/';
$config['allowed_types'] = 'gif|jpg|png';
$config['overwrite'] = TRUE;
$config['file_name'] = "$banner2";
$this->load->library('upload', $config);
$this->upload->data();
$this->upload->do_upload();
$this->upload->initialize($config);

我的代码有问题吗？上传不起作用。

is there any wrong with my code? The upload not working.

推荐答案

您不能简单地调用 do_upload 方法在初始化和设置上载类的配置变量之前。

You can not simply call do_upload method before initializing and setting config variables for the upload class.

您需要按以下方式修改代码：

You need to modify your code like this:

$config['upload_path'] = './assets/images/b2b/banner-agent/';
$config['allowed_types'] = 'gif|jpg|png';
$config['overwrite'] = TRUE;
$config['file_name'] = $banner2;
$this->load->library('upload'); //initialize
$this->upload->initialize($config); //Alternately you can set preferences by calling the initialize function. Useful if you auto-load the class
$this->upload->do_upload(); // do upload
if($this->upload->do_upload()){
    $this->upload->data(); //returns an array containing all of the data related to the file you uploaded.
}

您也可以参考 Codeigniter Wiki ：
