This document describes how to upload images using the CodeIgniter framework. We will share this with you for your reference. The details are as follows:

I have to repeat the conventional problem of uploading images once again, because the framework is worth learning and learning for some places. I wrote this article using official documents, however, in some cases, you need to mark it.

Next let's take a look at uploading images. First, create a view file text. php in the "./application/views/" folder. the code is as follows:

      Upload Form          
       
             

              

Codeigniter has its own rich upload class library. let's take a look at the Controller. in the Controller, an Upload. php file, the code is as follows:

class Upload extends CI_Controller{  public function construct(){    parent::construct();    $this->load->helper("form","url");  }  public function index(){    $this->load->view('test',array("error"=>''));  }  public function do_upload(){    $config['upload_path']='./uploads/';    $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('userfile')){      $error=array('error'=>$this->upload->display_errors());      $this->load->view('test',$error);    }else{      $data=array('upload_data'=>$this->upload->data());      $this->load->view('upload_success',$data);    }  }}

Next, create another file upload_success.php in the view.

      Upload Form        Your file was successfully uploaded!    
 
 
      
  $value):?>      
  
  
 :
