Update and override the image using CodeIgniter - php

Question

I'm stuck on a problem with updating image. I did upload the multiple image and inserted in database but I can not override these images in database or my upload folder how can I override the images in my upload folder and my database.
I do multiple image upload in CodeIgniter; the same code is used to update the the multiple image but in the update time:
public function edit_package($package_id){
$pname = $this->input->post('pname');
$pdur = $this->input->post('pdur');
$pdelprice = $this->input->post('pdelprice');
$price = $this->input->post('price');
$pcat = $this->input->post('pcat');
$pc = $this->input->post('pc');
$ploc = $this->input->post('ploc');
$pcat = $this->input->post('pcat');
$accom1 = $this->input->post('accom1');
$accom2 = $this->input->post('accom2');
$accom3 = $this->input->post('accom3');
$accom4 = $this->input->post('accom4');
$accom5 = $this->input->post('accom5');
$accom6 = $this->input->post('accom6');
// Displaying Errors in view
$this->form_validation->set_error_delimiters('<span style="color:red;">', '</span>');
$this->form_validation->set_rules('pname', 'Package Name', 'required');
$this->form_validation->set_rules('pdur', 'Package Duration', 'required');
$this->form_validation->set_rules('price', 'Package Price', 'required');
$this->form_validation->set_rules('pdelprice', 'Package offer Price', 'required');
$this->form_validation->set_rules('pc', 'Places Covered', 'required');
$this->form_validation->set_rules('pcat', 'Package Category', 'required');
$this->form_validation->set_rules('ploc', 'Package Location', 'required');
if ($this->form_validation->run() == False)
{
$data['editPackage'] = $this->Packages_model->editPackageVlaues($package_id);
$data['editPackage'] = $this->Packages_model->editPackageVlaues($package_id);
$data['editLocation'] = $this->Packages_model->edit_location();
$data['editPackCate'] = $this->Packages_model->getCategoryName();
$data['pkg_cat'] = $this->Packages_model->get_pkg_cat();
$data['pkg_loc'] = $this->Api_location_model->get_locations();
$this->load->view('Admin_panel/admin_assets');
$this->load->view('Admin_panel/panel');
$this->load->view('Admin_panel/Packages/edit_package',$data);
$this->load->view('Admin_panel/footer');
}
extract($_POST);
if(isset($update_package))
{
$filesCount = count($_FILES['pkg_img']['name']);
for($i = 0; $i < $filesCount; $i++)
{
$_FILES['userFile']['name'] = $_FILES['pkg_img']['name'][$i];
$_FILES['userFile']['type'] = $_FILES['pkg_img']['type'][$i];
$_FILES['userFile']['tmp_name'] = $_FILES['pkg_img']['tmp_name'][$i];
$_FILES['userFile']['error'] = $_FILES['pkg_img']['error'][$i];
$_FILES['userFile']['size'] = $_FILES['pkg_img']['size'][$i];
$config['upload_path'] = 'resources/neeraj/';
$config['allowed_types'] = 'gif|jpg|png|jpeg|GIF|JPEG|PNG|JPG';
$config['overwrite'] = TRUE;
$config['max_size'] = 2048000;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->upload->initialize($config);
if($this->upload->do_upload())
{
$fileData[] = $this->upload->data();
$fileName = $fileData['file_name'];
$images[] = $fileName;
$error = array('error' => $this->upload->display_errors());
$fileName = $this->upload->data('file_name');
if($this->Packages_model->update_packages($package_id,$pname,$pdur,$pdelprice,$price,$pcat,$ploc,$pc,$accom1,$accom2,$accom3,$accom4,$accom5,$accom6,$fileName))
{
$this->session->set_flashdata('package_update','Package Updated successfully');
redirect('Packages_ctrl/display_packages');
}
else
{
//upload the new image
$upload_data = $this->upload->data();
$fileName = $upload_data['file_name'];
if($_POST){
$data = array('pkg_img'=>$fileName);
//update
$this->Packages_model->update_packages($data);
}
echo "<script> alert('Please Select the Hotel Image');
window.location.href='add_packages';
</script>";
}
}
}
}
}

Answer 1

You should supply the overwrite config parameter
$config['upload_path'] = './uploads/';
$config['overwrite'] = TRUE;
$this->load->library('upload', $config);
$this->upload->initialize($config);
See the Documentation for upload preferences

Answer 2

I think you want to upload the multiple files using CodeIgniter. If I'm right then you have to follow this answer then definitely you got the solutions.
In View page:
<form action='index.php/upload/do_upload' enctype="multipart/form-data" method="post">
<input type="file" name="userfile[]" multiple='multiple' />
<input type="submit" value="upload" />
</form>
In Controller.
public function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 10000;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$config['overwrite'] = true;
$this->load->library('upload', $config);
$number_of_files_uploaded = count($_FILES['userfile']['name']);
for ($i = 0; $i < $number_of_files_uploaded; $i++) {
$_FILES['upl_files']['name'] = $_FILES['userfile']['name'][$i];
$_FILES['upl_files']['type'] = $_FILES['userfile']['type'][$i];
$_FILES['upl_files']['tmp_name'] = $_FILES['userfile']['tmp_name'][$i];
$_FILES['upl_files']['error'] = $_FILES['userfile']['error'][$i];
$_FILES['upl_files']['size'] = $_FILES['userfile']['size'][$i];
if ( ! $this->upload->do_upload('upl_files'))
{
$error = array('error' => $this->upload->display_errors());
var_dump($error);
$this->load->view('v_upload', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
var_dump( $data);
}
}
}
Please care about the name , it's important part here.
