Codeigniter image upload and path to database - php

Question

I'm having a bit of a problem trying to make an upload form in codeigniter.
Not sure what I am doing wrong, everything else is getting correctly in the database. I looked in the documentation and tried several things but I'm not getting any further.. Any feedback is very much appreciated!
Thanks in advance.
model:
public function set_newstudent()
{
$this->load->helper('url');
$slug = url_title($this->input->post('naam'), 'dash', TRUE);
$config['upload_path'] = '/file_path/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
$this->upload->data('full_path'););
$data_upload_files = $this->upload->data();
$image = $data_upload_files[full_path];
$data = array(
'naam' => $this->input->post('naam'),
'voornaam' => $this->input->post('voornaam'),
'id' => $slug,
'text' => $this->input->post('text'),
'picture'=>$this->input->post('picture')
);
return $this->db->insert('student', $data);
}
controller:
public function create()
{
$this->load->helper('form');
$this->load->library('form_validation');
$data['title'] = 'Create a new Student';
$this->form_validation->set_rules('naam', 'Naam', 'required');
$this->form_validation->set_rules('voornaam', 'Voornaam', 'required');
$this->form_validation->set_rules('text', 'Text', 'required');
if ($this->form_validation->run() === FALSE)
{
$this->load->view('templates/header', $data);
$this->load->view('students/create');
$this->load->view('templates/footer');
}
else
{
$this->student_model->set_newstudent();
$this->load->view('students/success');
}
}
view:
<?php echo validation_errors(); ?>
<?php echo form_open_multipart('student/create');?>
<div class="form-group">
<label for="naam">Naam</label><br>
<input type="input" name="naam" class="form-control" /><br />
</div>
<div class="form-group">
<label for="voornaam">Voornaam</label><br>
<input type="input" name="voornaam" class="form-control"/><br />
</div>
<div class="form-group">
<label for="text">Vertel iets over jezelf:</label><br>
<textarea name="text" class="form-control" rows="5"></textarea><br />
</div>
<div class="form-group">
<label for="text">Kies een profiel foto:</label><br>
<input type="file" name="userfile" class="btn btn-default btn-file" />
</div>
<input type="submit" class="btn btn-success" name="submit"
value="Create student" style="width:100%;margin-bottom:1%" />
</form>

Answer 1

As i see, there is no
$this->upload->do_upload()
That's the function responsible for performing the upload and it's not there in your code,you may want to read this:
File uploading Class
UPDATE
Your code should look something like this,
Controller:
public function create(){
$this->load->helper('form');
$this->load->library('form_validation');
$data['title'] = 'Create a new Student';
$this->form_validation->set_rules('naam', 'Naam', 'required');
$this->form_validation->set_rules('voornaam', 'Voornaam', 'required');
$this->form_validation->set_rules('text', 'Text', 'required');
if ($this->form_validation->run() === FALSE){
$this->load->view('templates/header', $data);
$this->load->view('students/create');
$this->load->view('templates/footer');
}else{
// Upload the files then pass data to your model
$config['upload_path'] = '/file_path/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
if (!$this->upload->do_upload('userfile')){
// If the upload fails
echo $this->upload->display_errors('<p>', '</p>');
}else{
// Pass the full path and post data to the set_newstudent model
$this->student_model->set_newstudent($this->upload->data('full_path'),$this->input->post());
$this->load->view('students/success');
}
}
}
Model:
public function set_newstudent($path,$post){
$data = array(
'naam' => $post['naam'],
'voornaam' => $post['voornaam'],
'text' => $post['text'],
'picture'=>$path
);
return $this->db->insert('student', $data);
}

Answer 2

The problem is in your code where you are using upload library. You are using the wrong function to upload files. Below is the correct code:
$config['upload_path'] = '/file_path/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
// Check file uploaded or not
if ($this->upload->do_upload('userfile')) {
$data_upload_files = $this->upload->data();
$image = $data_upload_files[full_path];
} else {
// possibly do some clean up ... then throw an error
}
This code should work.
