Can I Upload a Jpeg File to Inkarnate
File uploading in CodeIgniter has two primary parts—the frontend and the backend. The frontend is taken care of past the HTML grade that uses the form input blazon file. On the backend, the file upload library forms the submitted input from the course and writes information technology to the transfer registry.
This tutorial discusses the procedure of creating a CodeIgniter based file upload component that could be hands used to upload images and other files with ease. You could validate and even restrict file size and type during the upload process.
- Folder Creation
- Create the Controller
- Prepare File Upload Preferences
- The Course Helper
- Structural View
- The Success Message
- Conclusion
Folder Cosmos
The first footstep is the creation of ii folders that form the ground of the upload process. The commencement folder is the destination folder that would receive the uploaded files.
Next, go to the root of the CI installation and create a folder named "uploads".
Go to the view folder (located at the root of the CI installation) and create two new "view" files. Proper noun these files file_view.php (displays the course containing file upload fields) and upload_success.php (displays the upload successful message).

Create the Controller
The side by side stride is the cosmos of a file in the controller folder. Proper name the file upload_controller.php. In this file, I will load a library for initializing the Upload class through the following code:
$this->load->library('upload'); Set File Upload Preferences
I volition as well prepare the preferences for the file upload process through the controller functiondo_upload(). this function volition contain the following code:
$config['upload_path'] = './uploads/'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '100'; $config['max_width'] = '1024'; $config['max_height'] = '768';
As you lot could meet, through this function, you could hands restrict the upload path, allowed file types, maximum size and dimensions of the paradigm.
you could see this function in action when you call the file_view.php file. if you are at a staging domain, use the URL: your-domain/ci_demo/index.php/upload_controller/file_view OR in the case of loclhost: localhost/ci_demo/index.php/upload_controller/file_view

The Form Helper
Note that file upload requires a multipart grade. For this, I have included a class helper in the controller with the post-obit syntax:
$this->load->helper(array('form', 'url')); Y'all Might Also Like: Simple Guide to CodeIgniter Grade Validation
Structural View
For the structure of the paradigm upload, I will kickoff by creating a file in the views folder with the proper noun custom_view.php. Open this file and add together the following code to it:
<html> <head> <title>File Upload In Codeigniter</championship> </caput> <body> <?php repeat $error;?> <?php echo form_open_multipart('upload_controller/do_upload');?> <?php repeat "<input type='file' name='userfile' size='20' />"; ?> <?php echo "<input type='submit' proper noun='submit' value='upload' /> ";?> <?php echo "</grade>"?> </body> </html> Next, go to the controller binder and create a new file with the name upload_controller.php

Add the following code to this file:
<?php if ( ! defined('BASEPATH')) leave('No directly script access immune'); class Upload_Controller extends CI_Controller { public function __construct() { parent::__construct(); } public function custom_view(){ $this->load->view('custom_view', array('error' => ' ' )); } public function do_upload(){ $config = array( 'upload_path' => "./uploads/", 'allowed_types' => "gif|jpg|png|jpeg|pdf", 'overwrite' => TRUE, 'max_size' => "2048000", // Can be set to particular file size , hither information technology is ii MB(2048 Kb) 'max_height' => "768", 'max_width' => "1024" ); $this->load->library('upload', $config); if($this->upload->do_upload()) { $information = array('upload_data' => $this->upload->data()); $this->load->view('upload_success',$data); } else { $fault = array('error' => $this->upload->display_errors()); $this->load->view('custom_view', $fault); } } } ?> Notice that the array $config of the do_upload() has an element named allowed_types. You could utilize the parameters of this element to change the immune file types. For example, to allow a range of files, use the following structure of this element:
'allowed_types' => "gif|jpg|jpeg|png|iso|dmg|null|rar|dr.|docx|xls|xlsx|ppt|pptx|csv|ods|odt|odp|pdf|rtf|sxc|sxi|txt|exe|avi|mpeg|mp3|mp4|3gp",
The Success Bulletin
To display the upload successful bulletin, I will utilise the upload_success.php file (located in the view folder). Add the following code to it:
<html> <caput> <title>Success Message</title> </head> <body> <h3>Congragulation You Have Successfuly Uploaded</h3> <!-- Uploaded file specification will prove upwardly here --> <ul> <?php foreach ($upload_data equally $detail => $value):?> <li><?php repeat $particular;?>: <?php echo $value;?></li> <?php endforeach; ?> </ul> <p><?php repeat anchor('upload_controller/file_view', 'Upload Another File!'); ?></p> </body> </html> Annotation: Make certain that y'all are calling the correct path for the controller form
