Codeigniter create thumb image by custom dimensions, how? - codeigniter

I have Codeigniter custom system, need upload image standard dimensions + create _thumb into same folder without duplicate. This is working code without thumb image creator... Can you help me?

}

You can use CodeIgniter's built-in image_lib library which supports all three major image libraries: GD/GD2, NetPBM, and ImageMagick
Here is official documentation and here is a similar question addressing your issue. Hope this helps you.

You basically need to install ImageMagick on the server/localhost.
You can also check this link for a working example on how to create the thumbnail.

How can I upload file from Rest API in Codeigniter

I am new to codeigniter 3. I am accepting parameter as follows for saving a file from android app. I am receiving only the file path like this. However the exact file is not getting stored in the folder
file:///storage/emulated/0/Android/data/com.xyz/files/compressed/IMG_1599745033164.png
public function updateUsername(){
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, POST, OPTIONS');
header('Access-Control-Allow-Headers: Origin, Content-Type, Accept, Authorization, X-Request-With');
header('Access-Control-Allow-Credentials: true');
$nameval = $this->security->xss_clean($this->input->post('nameval'));
$image = base64_decode($nameval);
$image_name = md5(uniqid(rand(), true));
$filename = $image_name . '.' . 'jpg';
//rename file name with random number
$path = "uploads/categoryimages/".$filename;
//image uploading folder path
file_put_contents($path . $filename, $image);
}
I can share my code here which I have done for the same problem and its working.
JSON post Data format
Step 1: Convert image into base64 like
data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/4Q2CRXhpZgAASUkqAAgAAAAOAAsAAgAKAAAAtgmv/9k=
Step 2: Encode above base64 data by using base64 encoding. You will get code like
ZGF0YTppbWFnZS9qcGVnO2Jhc2U2NCwvOWovNEFBUVNrWkpSZ0FCQVFBQUFRQUJBQUQvNFEyQ1JYaHBaZ0FBU1VrcUFBZ0FBQUFPQUFzQUFnQUtBQUFBdGdtdi85az0=
Then use this encoded base64 into JSON object value
Post Data API: http://url/controller/function
{
"media_type": "png",
"imagecode": "ZGF0YTppbWFnZS9qcGVnO2Jhc2U2NCwvOWovNEFBUVNrWkpSZ0FCQVFBQUFRQUJBQUQvNFEyQ1JYaHBaZ0FBU1VrcUFBZ0FBQUFPQUFzQUFnQUtBQUFBdGdtdi85az0="
}

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.
public function add_record()
{

}else{
$this->session->set_flashdata('error','Error while adding record');

}
}
$where_array = array('vm_publications.status !=' => 4);
$data['users_type'] = $this->common_model->get_records('vm_image_category','','','');
$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.

Convert uploaded pdf file to jpg in 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'];

if($data['permission']=='Super Admin' || $data['permission']=='Admin'){
$this->load->view('header');
$this->load->view('upload_form', array('error' => ' ' ));
}
}
else
{

(`uploaded_id`, `name`, `path`,`department`,`uploader`)
VALUES ('','".$name."',
'". $path."','".$dept."','".$uploader."')");
redirect('csfi','refresh');
}
}

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

I want to download file in codeigniter

on this way i can upload image and pdf..
but i want to download the pdf or image from my view...please someone give me the code of downloading pdf or image from view..give me the full code
public function save_about_1() {

}
}
You can use the CI download helper for this.
$data = file_get_contents("/path/to/photo.jpg"); // Read the file's contents
$name = 'myphoto.jpg';
force_download($name, $data);
From the CI User Guide.
