Convert uploaded pdf file to jpg in codeigniter - codeigniter

I am currently beginning to learn CodeIgniter. There is this site that I've been working on.
In this site, users can upload PDF files but they are only allowed to view their uploaded files in JPG format. The question is, how can I convert the PDF file into JPG on the time of upload and store JPG format instead of PDF.
here is the code of my CONTROLLER
public function upload()
{
if($this->session->userdata('logged_in'))
{
$session_data = $this->session->userdata('logged_in');
$data['username'] = $session_data['username'];
$data['permission'] = $session_data['permission'];
if($data['permission']=='Super Admin' || $data['permission']=='Admin'){
$this->load->view('header');
$this->load->view('upload_form', array('error' => ' ' ));
}
}
else
{
redirect('login', 'refresh');
}
}
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'pdf';
$config['max_size'] = '10000';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('header');
$this->load->view('upload_form', array('error' => ' ' ));
}
else
{
$data = array('upload_data' => $this->upload->data());
$upload_data = $this->upload->data();
$session_data = $this->session->userdata('logged_in');
$first = $session_data['firstname'];
$last = $session_data['lastname'];
$dept = $session_data['department'];
$uploader = $first." ".$last;
$name = $upload_data['file_name'];
$path = $upload_data['file_path'];
$this->db->query("INSERT INTO tbl_uploaded
(`uploaded_id`, `name`, `path`,`department`,`uploader`)
VALUES ('','".$name."',
'". $path."','".$dept."','".$uploader."')");
redirect('csfi','refresh');
}
}
I've already read about Imagick but I don't know how to use it in CodeIgniter. Can you give me some tutorials and examples or a much easier way to convert PDF to JPG in CodeIgniter?
Thank you in advance guys.

Try this, you can upload and convert multiple files using this.

}
it is changing file name to encryption in folder but in mysql i'am getting file name same as old name with unchanged on non-encrypted format
It's because you're taking from $_FILES veriable. You should take from
$this->upload->data()
So how?
$fileData = $this->upload->data();
This will return
file_name
file_type
file_path
etc.
$fileName = $fileData['file_name']

Codeigniter news image resize

How to resize the news picture? I never could.
My problem [source_image]
I use Codeigniter 3.1.6
Controller
public function insert_news() {
$config['upload_path'] = 'uploads/news/';
$config['allowed_types'] = 'gif|jpg|png';
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
if ($this->upload->do_upload('news_image'))
{
$image = $this->upload->data();
$image_url = $image['file_name'];
$db_insert ='upload/news/'.$image_url.'';
$data=array(
'news_title' => $this->input->post('news_title'),
'news_content' => $this->input->post('news_content'),
'news_image' => $db_insert,
'news_sef'=>sef($this->input->post('news_title'))
);
$this->load->model('vt');
$result = $this->vt->insert_news($data);
if ($result) {
echo "yes";
} else {
echo "no";
}
}
}
You can try this solution for your problem :
Controller :
<?php
public function insert_news() {
$config['upload_path'] = 'uploads/news/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '20240000245';

// You can change width & height
$imgage_width= 60;
$imgage_height= 60;
$this->load->library('upload', $config);
$this->upload->initialize($config);
if (!$this->upload->do_upload($field)) {
$error = $this->upload->display_errors();
// uploading failed. $error will holds the errors.
$this->form_validation->set_message('error',$error);
return FALSE;
} else {
$fdata = $this->upload->data();
$configer = array(
'image_library' => 'gd2',
'source_image' => $fdata['full_path'],
'maintain_ratio' => TRUE,
'width' => $imgage_width,
'height' => $imgage_height,
);
// Load Image Lib Library
$this->load->library('image_lib');
$this->image_lib->clear();
$this->image_lib->initialize($configer);
$this->image_lib->resize();
$img_data ['path'] = $config['upload_path'] . $fdata['file_name'];
// uploading successfull, now do your further actions
$data=array(
'news_title' => $this->input->post('news_title'),
'news_content' => $this->input->post('news_content'),
'news_image' => $img_data ['path'],

How to use Multiple images in codeigniter

In my page I want user to select multiple images and upload it I am saving images name in database for reference. I am successful in uploading single images in database and can also show image in view but now I have problem in uploading multiple images.

$data['include'] = 'backend/image/add_image';
$this->load->view('backend/container', $data);
try below code in you add_record() function. it will helpful to you. few days ago, i have faced same problem
$files = $_FILES;
$count = count($_FILES['image']['name']);
for($i=0; $i<$count; $i++) {
$_FILES['image']['name']= $files['image']['name'][$i];
$_FILES['image']['type']= $files['image']['type'][$i];
$_FILES['image']['tmp_name']= $files['image']['tmp_name'][$i];
$_FILES['image']['error']= $files['image']['error'][$i];
$_FILES['image']['size']= $files['image']['size'][$i];
$this->upload->initialize($this->set_upload_options());//function defination below
$this->upload->do_upload('image');
$upload_data = $this->upload->data();
$name_array[] = $upload_data['file_name'];
$fileName = $upload_data['file_name'];
$images[] = $fileName;
}
$fileName = $images;
and set file upload configuration in set_upload_options function in same controller.
function set_upload_options() {
$config = array();
$config['upload_path'] = PATH;
$config['remove_spaces']=TRUE;
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '78000';
return $config;
}
First, debug the output of the $_FILES variable. This should give you an array of files that are being uploaded. Loop through them to treat each one individually.
foreach ($_FILES as $file) {
// do some file processing on the $file object instead of $_FILES object.
// example: instead of using 'if($_FILES['image']['name'])'
// use: 'if($file['image']['name'])'
}

how to do image upload in codeigniter?

I am trying to upload an image in root folder and its file name in database. here is what I did for the upload function:
public function add_blog($id=0){
if(!empty($_FILES['picture']['name'])){
$config['upload_path'] = 'uploads/blog_image';
$config['allowed_types'] = 'jpg|jpeg|png|gif';
$config['file_name'] = $_FILES['picture']['name'];
//Load upload library and initialize configuration
$this->load->library('upload',$config);
$this->upload->initialize($config);
// print_r($value['name'][$s]);exit;
if($this->upload->do_upload('picture')){
$uploadData = $this->upload->data();
$picture = $uploadData['file_name'];
print_r($picture); exit;
}
}
print_r($config['file_name']); exit;
$data['blog_data']=array('blog_post'=>$this->input->post('blog_post'),
'posted_by'=>$this->input->post('posted_by'),
'blog_image'=>$picture);
if ($id==0){
$this->db->insert('blog',$data['blog_data']);
// $last_id = $this->db->insert_id();
}
else {
$this->db->where('id',$id);
// $last_id = $this->db->insert_id();
$this->db->update('blog',$data['blog_data']);
}
}
problem here is i am being able to insert other data except image. I get the image name with that print_r($config[file_name]) if i do print_r() and exit, if not it will just insert other data except image. But the image is neither uploaded in root folder nor its name in database. If I give the non existing upload path, then also its not throwing any error. I think code inside If is not executed. How can i solve this ? Thanks in advance.
private function _upload_image( ) {
$this->load->library( 'upload' );
if ($_FILES && $_FILES['picture']['name'] !== ""){
$config['upload_path'] = 'uploads/blog_image';
$config['allowed_types'] = 'jpg|jpeg|png|bmp';
$config['max_size'] = 10000;
/*the picture name must be unique, use function now()*/
$config['file_name'] = $_FILES['picture']['name'] . now();
$config['file_ext_tolower'] = TRUE;
$this->upload->initialize( $config );
if ( $this->upload->do_upload( 'picture' ) ){
$file_name = $this->upload->data()['file_name'];
$full_path = $this->upload->data()['full_path'];
/*If you want create a thumb, use this part*/
$this->load->library('image_lib');
$config = array(
'source_image' => $path,
'new_image' => $this->_image_path,
'maintain_ratio' => true,
'width' => 128,
'height' => 128,
'create_thumb' => TRUE,
'thumb_marker' => '_thumb',
);
$this->image_lib->initialize( $config );
$this->image_lib->resize();
/*Save in database*/
$this->db->insert('blog', [
'file_name' => $file_name,
'full_path' => $full_path
]);
} else {
//if picture is empty, do something
}
}
}
You do not need to use $_FILES && $_FILES ['picture']['name']! == "" only if your form has the picture field as an optional field, $this->upload->do_upload('picture') and get data from $this->upload->data(), read the manual
public function add_blog()
{
$config['upload_path'] = '.uploads/blog_image';
$config['allowed_types'] = 'jpg|jpeg|png|gif';
$config['max_size'] = 10000;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('picture'))
{//Do something with errors
$errors = $this->upload->display_errors();
}
else
{
$data = $this->upload->data();
$this->db->insert('blog', [
'file_name' => $data['file_name'],
'full_path' => $data['full_path']
]);
}
}
I just didn't mention the file size to be uploaded. I did this in my above code and worked.
EDIT
public function add_blog($id=0){
if(!empty($_FILES['picture']['name'])){
$config['upload_path'] = 'uploads/blog_image';
$config['allowed_types'] = 'jpg|jpeg|png|gif';
$config['max_size'] = 0;
$config['file_name'] = $_FILES['picture']['name'];
//Load upload library and initialize configuration
$this->load->library('upload',$config);
$this->upload->initialize($config);
// print_r($value['name'][$s]);exit;
if($this->upload->do_upload('picture')){
$uploadData = $this->upload->data();
$picture = $uploadData['file_name'];
// print_r($picture); exit;
}
}
// print_r($config['file_name']); exit;
$data['blog_data']=array('blog_post'=>$this->input->post('blog_post'),
'posted_by'=>$this->input->post('posted_by'),
'blog_image'=>$picture);
if ($id==0){
$this->db->insert('blog',$data['blog_data']);
// $last_id = $this->db->insert_id();
}
else {
$this->db->where('id',$id);
// $last_id = $this->db->insert_id();
$this->db->update('blog',$data['blog_data']);
}
}
And this code works for both insert and update.
