我将图像上传到“images”目录，并将一些信息上传到codeigniter中的数据库。但是当我在完成表单后点击提交按钮时，它什么也没有发布。它给出了没有发布任何输入的错误（与错误消息的含义不同）。如果有人可以请查看此代码，并告诉我为什么它不起作用。先感谢您。这是我的控制器代码：
<?php
public function create()
{
// image1
$ImageName = $_FILES['image']['name'];
$imageSize= $_FILES['image']['size'];
$imageSource = $_FILES['image']['tmp_name'];
move_uploaded_file($_FILES['image']['tmp_name'], "images/$ImageName");
$this->create_thumb($ImageName);
$this->compress($ImageName, $imageSize, "images/$ImageName");
// image2
if ($this->input->post('image2'))
{
$ImageName2 = $_FILES['image2']['name'];
$imageSize2= $_FILES['image2']['size'];
$imageSource2 = $_FILES['image2']['tmp_name'];
$this->compress($ImageName2, $imageSize2, $imageSource2);
}
// image3
if ($this->input->post('image3'))
{
$ImageName3 = $_FILES['image3']['name'];
$imageSize3= $_FILES['image3']['size'];
$imageSource3 = $_FILES['image3']['tmp_name'];
$this->compress($ImageName3, $imageSize3, $imageSource3);
}
// image4
if ($this->input->post('image4'))
{
$ImageName4 = $_FILES['image4']['name'];
$imageSize4= $_FILES['image4']['size'];
$imageSource4 = $_FILES['image4']['tmp_name'];
$this->compress($ImageName4, $imageSize4, $imageSource4);
}
$this->news_model->set_news();
$this->load->view('News/success');
}
?>

首先检查$ _FILES是否有任何数据。
print_r($_FILES);
如果它有任何数据然后尝试改变条件，如。代替
if ($this->input->post('image2')){
使用以下
if( isset( $_FILES['image']['name']) and $_FILES['image']['name'] != '' ) {
// Your code
}

你的控制器应该是这样的
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Controller_name extends CI_Controller{
public function __construct(){
parent::__construct();
$this->load->model('your_model');
$this->load->library('upload');
}
public function function_name(){
if($this->input->post('submit')){
/* Your Function */
}
OR Use
if($_POST){
/* Your Function */
}
$this->load->view('News/success');
}
答案 2 :(得分：0)
if ($this->input->post('image3')){ /* ... */ }错了。 PHP不会看到上传的文件。请将它们检查为：if (array_key_exists($_FILES, 'image3')){ /* ... */ }
