I want upload image with fixed size in codeigniter.But my code is not working.Anyone please help me for doing this..My code is
public function createevent() {
if ($this->input->post('submit')) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_width'] = '366';
$config['max_height'] = '269';
$this->load->library('upload', $config);
// $data = array('upload_data' => $this->upload->data());
$data = $this->upload->data();
$logo = $data['file_name'];
$fileInfo = getimagesize($data);
if( $fileInfo['width'] == 366 && $fileInfo['height'] == 269 ) {
// if(($fileInfo[0] == 366) && ($fileInfo[1] == 269 )){
// if ($this->upload->do_upload()) {
$this->event_model->createevent( $logo);
$this->session->set_flashdata('msg', 'Event Created');
} else {
// $this->image_lib->resize();
$this->session->set_flashdata('error', 'Please upload image within the size limit');
redirect('event/events');
}
}
}
Please use $fileInfo['image_width'] & $fileInfo['image_height'] instead of
$fileInfo['width'] & $fileInfo['height']
This will work. :)

currently I'm working with codeigniter framework but I'm confused how to resize the image. I have followed the documentation but I'm still confused. This is my code
public function create(){
//Check login
if(!$this->session->userdata('logged_in')){
redirect('users/login');
}
$data['title'] = 'Create Post';
$data['categories'] = $this->BlogModel->get_categories();
$this->form_validation->set_rules('title','title','required');
$this->form_validation->set_rules('content','content','required');
if($this->form_validation->run() === FALSE){
$this->load->view('frontend/header');
$this->load->view('frontend/navbar');
$this->load->view('frontend/blog/create',$data);
$this->load->view('frontend/footer');
} else{
//Upload Image
$config['upload_path'] = './assets/images/posts/blog';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '2048';
$config['max_width'] = '0';
$config['max_height'] = '0';
$this->load->library('upload', $config);
if(!$this->upload->do_upload()){
$errors = array('error' => $this->upload->display_errors());
$post_image = 'noimage.jpg';
}else{
$data = array('upload_data' => $this->upload->data());
$post_image = $_FILES['userfile']['name'];
}
$this->BlogModel->create_post($post_image);
//set message
$this->session->set_flashdata('post_created','Your post has been created');
redirect('blog');
}
}
Please advice how to resize the image.
Thanks!
If you want to do different things like resize the original image directly, rather than creating a thumb set create_thumb to false, and do not use new_image. The only difference between create_thumb and new_image is that new_image allows you to specify your own path and name. Whereas the most you can do with create_thumb is change the thumb_marker. Which is all in the docs...
//Upload Image
$config['upload_path'] = './assets/images/posts/blog';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '2048';
$config['max_width'] = '0';
$config['max_height'] = '0';
$this->load->library('upload', $config);
if (!$this->upload->do_upload()) {
//$errors = array('error' => $this->upload->display_errors());
exit($this->upload->display_errors());
$post_image = 'noimage.jpg';
} else {
$up_data = $this->upload->data();
$post_image = $up_data['name'];
$config = array(); // clear prev config
$config['image_library'] = 'gd2';
$config['source_image'] = $up_data['full_path'];
$config['create_thumb'] = TRUE;
$config['thumb_marker'] = '_thumbnail';
$config['maintain_ratio'] = TRUE;
$config['width'] = 75;
$config['height'] = 50;
$this->load->library('image_lib', $config);
if(!$this->image_lib->resize()) {
exit($this->image_lib->display_errors());
}
$thumb_path = $up_data['file_path'] . $up_data['raw_name'] . $config['thumb_marker'] . $up_data['file_ext'];
}
The exits you can remove later, but leave them for debugging until you figure out a way to properly message your errors (I suggest session vars). These functions should also be moved to a model.
Codeigniter: File successfully upload when setting only one field(individual). But when setting both field second file is also uploaded to first's location. How to solve this conflict.
Is there any tutorial for multiple upload field????
My code is given below:

I think you should do only one function to upload images that has data array as parameter where you may include the path and other variables.
public function upload(array $data)
{
$config['upload_path'] = isset($data['upload_path']) ? $data['upload_path'] : 'default/path';
...
$this->load->library('upload', $config);
if (!$this->upload->do_upload($data['field')) {
//no file uploaded or failed upload
$error = array('error' => $this->upload->display_errors());
} else {
$dat = array('upload_data' => $this->upload->data());
$this->resize($dat['upload_data']['full_path'], $data['upload_path'].$dat['upload_data']['file_name'],135,300);
}
...
}
When you submit the form, check for all input fields with the $_FILES global and call the upload function when necessary with the upload array $data set for each of them.
My image is not get inserted while uploading using codeigniter:
function add_newblog()
{
$sess_id = $this->session->userdata('id');
$result['query'] = $this->login_model->profile($sess_id);
foreach($result['query'] as $row)
{
$email = $row->blogger_email;
$url = $row->blogger_url;
$author = $row->blogger_name;
if ($this->input->post('submit')) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '0';
$config['max_width'] = '0';
$config['max_height'] = '0';
$this->load->library('upload', $config);
if (!$this->upload->do_upload()) {
$error = array('error' => $this->upload->display_errors());
$media = 'No Image Uploaded';
$title = $this->input->post("title");
$category = $this->input->post('category');
$content = $this->input->post('content');
$this->blog_model->add_newblog($sess_id,$title,$category,$content,$media,$email,$url,$author);
$this->session->set_flashdata('valid', 'Blog Created without Image');
redirect('content_writer/add_blog');
}
else {
$data = array('upload_data' => $this->upload->data());
$data = $this->upload->data();
$media = $data['file_name'];
$title = $this->input->post("title");
$category = $this->input->post('category');
$content = $this->input->post('content');
$this->blog_model->add_newblog($sess_id,$title,$category,$content,$media,$email,$url,$author);
$this->session->set_flashdata('valid', 'Blog Created');
redirect('content_writer/add_blog');
}
}
else{
$this->session->set_flashdata('invalid', 'Invalid');
redirect('content_writer/add_blog');
}
}
}
The else condition always works. The image name does not get saved in the image path.
the problem is here in this line
$config['upload_path'] = './uploads/';
instead use
$config['upload_path'] = 'uploads/<folder name>';
OR incase you want to save the image directly in uploads folder just use
$config['upload_path'] = 'uploads/';
as well as make your that you form in the veiw section is open with form_open_multipart()
hope this will solve your problem
Set your max_size, max_width and max_height. This would be an example below.
$config['max_size'] = '3000';
$config['max_width'] = '1500';
$config['max_height'] = '1500';
You havent passed the image name in $this->upload->do_upload() method.
use your
input type='file' name=myDoc
$this->upload->do_upload("myDoc")
How do I upload an image when I'm trying to save other data along with it? When the form submits, it hits the save function:
function save() {
$this->save_data($_POST, $_FILES);
}
function save_data($post_data, $file_data) {
// if theres an image
if(!empty($file_data['image']['size'])) {
$path = '/images';
$this->upload_image($path);
}
}
function upload_image($path) {
// CI is looking for $_FILES super global but I want to pass that data in
$config['upload_path'] = $path;
$config['allowed_types'] = 'jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
$this->upload->data('image');
$this->upload->do_upload('image');
}
I can't figure out how to actually pass the file data to another function. All the examples I've seen shows the form submitting to a function that uploads the function right from it. I want to do the uploading from another function though.
if you are trying to check if file is actually beeing uploaded do following
//this is optional
if (empty($_FILES['userfile']['name'])) {
$this->form_validation->set_rules('userfile', 'picture', 'required');
}
if ($this->form_validation->run()) { //if using validation
//validated
if (!empty($_FILES['userfile']['name'])) {
//picture is beeing uploaded
$config['upload_path'] = './files/pcitures';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
if (!$this->upload->do_upload('userfile')) {
//$error = array('error' => $this->upload->display_errors());
} else {
//no error, insert/update in DB
$tmp = $this->upload->data();
echo "<pre>";
var_dump($tmp);
echo "</pre>";
}
} else { ... }
}
My mistake was related to folder permissions.
For those of you that are looking to split the upload functionality into multiple functions:
Controller:
$save_data = $this->save_model->save_data($_POST, $_FILES);
Model:
function save_data($data, $file) {
// check if theres an image
if (!empty($file['image']['size'])) {
// where are you storing it
$path = './images';
// what are you naming it
$new_name = 'name_' . random_string('alnum', 16);
// start upload
$result = $this->upload_image($path, $new_name);
}
}
function upload_image($path, $new_name) {
// define parameters
$config['upload_path'] = $path;
$config['allowed_types'] = 'jpg|png';
$config['max_size'] = '1000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$config['file_name'] = $new_name;
$this->load->library('upload', $config);
// upload the image
if ($this->upload->do_upload('image')) {
// success
// pass back $this->upload->data() for info
} else {
// failed
// pass back $this->upload->display_errors() for info
}
}
I just learn to save image data to database, those are filename and path. The path is appear on database, but not with filename. Whats the problem?
This is the controller,
function do_upload() {
$config['upload_path']='./uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
$this->upload_model->upload($config);
if(!$this->upload->do_upload()){
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
} else {
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
and the model
function upload ($config) {
$config = $this->upload->data();
$upload_data = array(
'path' => $config['full_path'],
'nama_foto' => $config['file_name']
);
$this->db->insert('tb_picture', $upload_data);
}
and the table
what should i do?
thank you before.
before reading this please try it again yourself, or try any kind of viedotutorial that is on the web http://net.tutsplus.com/sessions/codeigniter-from-scratch/
controller function should look like this
function do_upload()
{
$config['upload_path']='./uploads/'; //needs to set uploads folder CHMOD 0644
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$config['overwrite'] = FALSE;
$config['remove_spaces'] = TRUE;
$field_name = "userfile"; //name tag in our HTML form in case you want to change it
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload($field_name)) //upload happens
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
//succesful upload get data from upload and use them with our model
$upload_data = $this->upload->data();
$this->upload_model->upload($upload_data);
}
}
model function
function upload ($data) {
if (empty($data) || $data === FALSE) return FALSE;
$insert_data = array(
'path' => $data['full_path'],
'nama_foto' => $data['file_name']
);
$this->db->insert('tb_picture', $insert_data);
return $this->db->insert_id(); //returns last inserted ID
}
Please note that your model was totaly "wrong" you used upload function in it, try to pass data only to it so model can process it.
