Codeigniter file upload from a form without ajax/jquery/javascript - php

Question

Context : I am updating user_profile data after user registration using form #updateprofileform ,
i am able to process all other form fields using standard validations and insert/update using user_model.
issue is with resume field which should accept a file as input type and upload to server and store its path on server (say http://domain/uploads/$filename) to a column in database.
Expectation A logged in user , able to view his details(if already in database),update details if incomplete profile.
Question : I found methods how we can upload a file to server using CI framework or how we can upload a file in this context using jquery/ajax/java-script. But i am looking for simple solution for above problem which can do the job with out dependency on technologies.
user_profile.php (view)
<table>
<form class="row" name="updateprofile" action = "<?php echo base_url()?>user/user_profile" method="POST">
<tr>
<td><label for="email">Email ID</label></td><td><input class="form-control" name="email" placeholder="Email-ID" type="text" value="<?php if (isset($email)) echo $email;?>" /> <span style="color:red"><?php echo form_error('email'); ?></span></td>
</tr>
<tr>
<td><label for="resume">Resume</label></td>
<td>
<input name="resume" placeholder="Upload resume" type="file" value="<?php if (isset($resume)) echo $resume;?>" />
<span style="color:red"><?php echo form_error('resume'); ?>
</span>
</td>
</tr>
<tr>
<td></td>
<td><div class="col-md-6 col-lg-3"> <button type="submit" class="btn btn--primary type--uppercase" name="updateprofile" value="updateprofile" formaction = "<?php echo base_url()?>user/user_profile">Update Profile</button> </div></td>
</tr>
</form>
</table>
user_controller
class User extends CI_Controller {
public function __construct()
{
parent::__construct();
$config = array(
'upload_path' => "./uploads/",
'allowed_types' => "doc|docx|pdf",
'overwrite' => TRUE,
'max_size' => "2048000", // Can be set to particular file size , here it is 2 MB(2048 Kb)
//'max_height' => "768",
//'max_width' => "1024"
);
$this->load->library('upload', $config);
}
public function user_profile()
{
$resume = $this->input->post('resume');
if ($this->user_model->set_user_profile($id,FALSE) )
{ if($this->do_upload($resume)){
$this->session->set_flashdata('msg_success','Updation Successful!');
echo validation_errors();}
}
else
{
$this->session->set_flashdata('msg_error','Error! Please try again later.');
redirect('user/user_profile');
}
public function do_upload($resume){
if($this->upload->do_upload($resume))
{
$data = array('upload_data' => $this->upload->data($resume));
$this->load->view('user_profile',$data);
}
else
{
$error = array('error' => $this->upload->display_errors($resume));
$this->load->view('user_profile', $error);
}
}
currently always error.... Error! Please try again later . so appreciate some pointers here to upload both file and form data together and save file location in database without ajax/jquery.
Thanks

Answer 1

Change the form definition to the following:
<form class="row" action = "<?php echo base_url('user/user_profile'); ?>" method="post" enctype="multipart/form-data" name="updateprofile" >

Answer 2

Resolved !
4 important steps needed and some missing in most Q&A in all other posts to make this complete.will share samplecode in github when i get sometime.
form encryption type must be enctype="multipart/form-data" (thanks
to #Javier Larroulet and #dexter )
do_upload method by default look for file field with name=userfile
(Thanks to #Alex ! for referencing this), so, if you have your
form's file field name different than userfile, then only it is
required to mention as do_upload('filefieldname') otherwise
optional
loading of upload library configuration is tricky.. if you
autoupload the upload library , then load->library upload config will fail!, you
just =>initialize it.$this->upload->initialize($config); if you
are not using autoload for upload library, then yes, you can load it
from controller. $this->load->library('upload', $config);
when ever, you are using upload, you have to catch the form validation errors
and data errors separately (again thanks to #Alex for pointing this)
a nice documentation is given from codeigniter at this link (https://www.codeigniter.com/userguide3/libraries/file_uploading.html#the-controller ) but doesn't highlight routine mistakes.
hope this post help someone not to waste another 24 hours to debug.
