codeigniter 3-你没有选择一个文件上传 [英] codeigniter 3- You did not select a file to upload

问题描述

Post_plot.php（这是我的查看表单）

 < form action =http：// localhost：8080 / ci / admin / plot / do_uploadenctype =multipart / form-datamethod =post> 
 
< input type =textname =property_titlevalue =/> 
 
< input type =filename =imgid =plot-imgvalue =/> 
 
< input type =submitname =submitvalue =Submit/> 
 
< / form> 
  

我有一个长形式的图片上传选项。

我正在使用do_upload函数来上传文件

我得到以下错误

  Array（[name] => a.jpg [type] => image / jpeg [tmp_name] => C：\xampp\tmp\phpBD75.tmp [error] = > 0 [size] => 132277）Array（[error] => 
您没有选择要上传的文件。
 
）
   
 
 
 $ p $ < ？php 
 defined（'BASEPATH'）或者exit（'不允许直接访问脚本'）; 
 
 class Plot extends CI_Controller {
 
 
 public function __construct（）
 {
 parent :: __ construct（）; 
 $ this-> load->库（'Admin_layout'）; 
 $ this-> load->模型（'admin / plot_model'）; 
 $ this-> config-> load（'plot_rules'）; 
 $ this-> output-> enable_profiler（TRUE）; 
 
 
 $ b $ public function do_upload（）
 {
 $ config ['upload_path'] ='../images/'; 
 $ config ['allowed_types'] ='gif | jpg | png'; 
 $ config ['max_size'] = 100; 
 $ config ['max_width'] = 1024; 
 $ config ['max_height'] = 768; 
 
 $ this-> load->库（'upload'，$ config）; 
 $ b $ if（！$ this-> upload-> do_upload（$ img））
 {
 $ error = array（'error'=> $ this-> ; upload->的display_errors（））; 
 
 print_r（$ error）; 
 
 
 
 $ data = array（'upload_data'=> $ this-> upload-> data（））; 
 
 // $ this-> load-> view（'upload_success'，$ data）; 
 print_r（$ data）; 
} 
} // do_upload 
 
 
} // class 
  

我应该在do_upload函数中传递任何参数吗？

解决方案

/ b>



  $ img =img//输入名称=img
 $ this->上传 - > do_upload（$ img）

您可能需要在你的ro上设置一些路线





$ b $ <？php defined（' BASEPATH'）或退出（'不允许直接访问脚本'）;

class Plot extends CI_Controller {

public function __construct（）
{$ b $ parent :: __ construct（）;
$ this-> load->库（'Admin_layout'）;
$ this-> load->模型（'admin / plot_model'）;
$ this-> config-> load（'plot_rules'）;
$ this-> output-> enable_profiler（TRUE）;


public function index（）{
$ this-> load-> view（'upload_form'，array（'error'=&';'）） ;


public function do_upload（）
{
$ config ['upload_path'] ='./images/';
$ config ['allowed_types'] ='gif | jpg | png';
$ config ['max_size'] = 100;
$ config ['max_width'] = 1024;
$ config ['max_height'] = 768;

$ this-> load->库（'upload'，$ config）;

$ img =img;
$ b $ if（！$ this-> upload-> do_upload（$ img））
{
$ error = array（'error'=> $ this-> ; upload->的display_errors（））;
$ this-> load-> view（'upload_form'，$ error）;

print_r（$ error）;



$ data = array（'upload_data'=> $ this-> upload-> data（））;

$ field_data = $ this-> upload-> data（）;

echo $ field_data ['file_name']; // etc

$ this-> load-> view（'upload_success'，$ data）;
print_r（$ data）;
}
}
}


Post_plot.php (This is my view form)

<form action="http://localhost:8080/ci/admin/plot/do_upload" enctype="multipart/form-data" method="post">

<input type="text" name="property_title" value=""  />

<input type="file" name="img" id="plot-img" value=""  />

<input type="submit" name="submit" value="Submit" />

</form> 

I have a long form with an image upload option.

I am using do_upload function to upload file

I am getting following error

Array ( [name] => a.jpg [type] => image/jpeg [tmp_name] => C:\xampp\tmp\phpBD75.tmp [error] => 0 [size] => 132277 ) Array ( [error] =>
You did not select a file to upload.

)

Plot.php Controller

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Plot extends CI_Controller {


    public function __construct()
    {
        parent::__construct();
        $this->load->library('Admin_layout');
        $this->load->model('admin/plot_model');
        $this->config->load('plot_rules');
        $this->output->enable_profiler(TRUE);
    }


    public function do_upload()
    {
            $config['upload_path']          = '../images/';
            $config['allowed_types']        = 'gif|jpg|png';
            $config['max_size']             = 100;
            $config['max_width']            = 1024;
            $config['max_height']           = 768;

            $this->load->library('upload', $config);

            if ( ! $this->upload->do_upload($img))
            {
                    $error = array('error' => $this->upload->display_errors());

                    print_r($error);
            }
            else
            {
                    $data = array('upload_data' => $this->upload->data());

                    //$this->load->view('upload_success', $data);
                    print_r($data);
            }
    }//do_upload


}//class

Should i pass any parameters in do_upload function?

解决方案

In this part try to put the

$img = "img" // input name="img"
$this->upload->do_upload($img)

If not try / test with form action="http://localhost:8080/ci/admin/plot/do_upload"

You may need to set some routes in your route.php

Code

<?php defined('BASEPATH') OR exit('No direct script access allowed');

class Plot extends CI_Controller {

public function __construct()
{
    parent::__construct();
    $this->load->library('Admin_layout');
    $this->load->model('admin/plot_model');
    $this->config->load('plot_rules');
    $this->output->enable_profiler(TRUE);
}

public function index() {
   $this->load->view('upload_form', array('error' => ' ' ));
}

public function do_upload()
{
        $config['upload_path'] = './images/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size']  = 100;
        $config['max_width']  = 1024;
        $config['max_height'] = 768;

        $this->load->library('upload', $config);

        $img = "img";

        if ( ! $this->upload->do_upload($img))
        {
                $error = array('error' => $this->upload->display_errors());
                $this->load->view('upload_form', $error);

                print_r($error);
        }
        else
        {
                $data = array('upload_data' => $this->upload->data());

                $field_data = $this->upload->data();

                echo $field_data['file_name']; // etc 

                $this->load->view('upload_success', $data);
                print_r($data);
        }
}
}
