I have a problem making thumbs after an image upload. I can upload images perfectly but it doesn't make thumbs for me. I have a map uploads where the original images are stored and a map thumbs in uploads. It's probably a path issue i guess. Thanks
This is my code in my controller.
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '6000';
$config['max_width'] = '3024';
$config['max_height'] = '3768';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
}
$datap = array('upload_data' => $this->upload->data());
$gallery_path = realpath(APPPATH . '../uploads');
$upload_data = $this->upload->data();
$config['image_library'] = 'gd2';
$config['source_image'] = $upload_data['full_path'];
$config['new_image'] = $gallery_path . '/thumbs';
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 75;
$config['height'] = 50;
$this->load->library('image_lib', $config);
$this->image_lib->resize();

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.
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'jpg|jpeg|png|gif';
$config['maintain_ratio'] = TRUE;
$config['width'] = 100;
$config['height'] = 150;
$config['file_name'] = $_FILES['image']['name'];
$this->load->library('image_lib', $config);
$this->image_lib->resize();
$this->image_lib->initialize($config);
$this->load->library('upload',$config);
$this->upload->initialize($config);
I am unable to resize image ... please give me my mistake
As per the #jigar Shah comment you have to first initalize upload library before resize
$this->load->library('upload');
$config['upload_path'] = './uploads';
$config['allowed_types'] ='csv|xls|xlsx';
$config['max_size'] = 1024; //in KB
$config['overwrite'] = TRUE;
$config['encrypt_name'] = TRUE;
$config['max_filename'] = 25;
$this->upload->initialize($config);
if (!$this->upload->do_upload('image_name')) {
//if file upload failed then catch the errors
$this->handle_error($this->upload->display_errors());
$is_file_error = TRUE;
} else {
//store the file info
$image_data = $this->upload->data();
$config['image_library'] = 'gd2';
$config['source_image'] = $image_data['full_path']; //get original image
$config['maintain_ratio'] = TRUE;
$config['width'] = 150;
$config['height'] = 100;
$this->load->library('image_lib', $config);
if (!$this->image_lib->resize()) {
$this->handle_error($this->image_lib->display_errors());
}
}

I want to upload large images on my website. I want to reduce the size of those using codeigniter. So I am doing this code
function upload_image($data) {
$config['upload_path'] = './temp/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 10000;
$this->load->library('upload', $config);
if (!$this->upload->do_upload('image')) {
$error = array('error' => $this->upload->display_errors());
pre($error);
} else {
$config = array();
$data = array('upload_data' => $this->upload->data());
$config['image_library'] = 'gd';
$config['source_image'] = './temp/' . $data['upload_data']['file_name'];
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['quality'] = 50;
$config['new_image'] = './temp/' . $data['upload_data']['file_name'];
$this->load->library('image_lib', $config);
$this->image_lib->resize();
pre($data);
}
}
But images are not being compressed. Original and uploaded size are the same. Where am I wrong?
Maybe exists an error. Check for errors:
if (!$this->image_lib->resize()){
echo $this->image_lib->display_errors();
}
Note: Use gd2 as library (default value is gd2):
$config['image_library'] = 'gd2';
I've been trying to upload and resize an image. The upload seems to be finally be working, but it's not resizing.
In my constructor I am loading the library
$this->load->library('image_lib');
and then in my function I'm calling the the resize and upload
$this->require_auth();
$img = $this->input->post('photo1');
$config['upload_path'] = './HTML/files/';
$config['file_name'] = 'photo1.jpg';
$config['file_path'] = './HTML/files/photo1.jpg';
$config['max-size'] = 2000;
$config['image_library'] = 'gd2';
$config['source_image'] = $config['file_path'];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = FALSE;
$config['width'] = 549;
$config['height'] = 549;
$config['overwrite'] = TRUE;
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['new_image'] = $config['file_path'];
$this->load->library('image_lib', $config);
$this->image_lib->resize();
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('photo1')){
$error = array('error' => $this->upload->display_errors());
var_dump($error);
}else{
$this->blog_model->editServiceImg1($config['file_path']);
redirect('/blog');
}
I have also tried this
$this->require_auth();
$img = $this->input->post('service_photo1');
$config['upload_path'] = './HTML/files/';
$config['file_name'] = 'service_photo1.jpg';
$config['file_path'] = './HTML/files/service_photo1.jpg';
$config['max-size'] = 2000;
$config['overwrite'] = TRUE;
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('service_photo1')){
$error = array('error' => $this->upload->display_errors());
var_dump($error);
}else{
$config['image_library'] = 'gd2';
$config['source_image'] = $config['file_path'];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = FALSE;
$config['width'] = 549;
$config['height'] = 549;
$config['new_image'] = $config['file_path'];
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->blog_model->editServiceImg1($config['file_path']);
redirect('/blog');
}
Is there something I'm missing? I've tried doing the resize after the initial upload as well and that seemed to do nothing as well. Any help would be much appreciated.
$this->load->library('image_lib');
$config['image_library'] = 'gd2';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['upload_path'] = './HTML/files/';
$config['file_path'] = './HTML/files/photo1.jpg';
$config['source_image'] = $config['file_path'];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 75;
$config['height'] = 50;
$this->image_lib->clear();
$this->image_lib->initialize($config);
$this->image_lib->resize();
If the above code won't work then please check the folder permissions where the images are upload.
You can also give 777 permission to the folder in following manner :-
sudo chmod -R 777 path
Solution will surely help you
I went through this code many times and finally resolved this issue. It seems that when you have
$config['create_thumb'] = TRUE;
in your code it will create a thumbnail with the resized proportions and if you do not tell it where to go it will hide it in a folder. So the resizing was working, just not on the right image.
To resolve this, I changed the above to.
$config['create_thumb'] = FALSE;
I want to upload an image in three foler. My folder structure is like:
upload/large,upload/original,upload/thumb.
How to store the image after resizing into these folders using codeigniters 'upload' library.
I agree with Natrium, you need to accept more answers.
However, for this question:
It looks to me like you're only actually uploading to the original folder and then using the image library on this copy, so, try the following:
$config['upload_path'] = './upload/original';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '500';
$config['max_height'] = '300';
$this->load->library('upload', $config);
$this->upload->do_upload()
$upload_data = $this->upload->data();
$copies = array(
array('dir' => 'upload/large', 'x' => 1000, 'y' => 600), //note: x&y could be replaced with a percentage or ratio etc.
array('dir' => 'upload/thumbnail', 'x' => 100, 'y' => 60)
);
foreach($copies as $copy)
{
$config['image_library'] = 'ImageMagick';
$config['library_path'] = '/usr/bin/';
$config['source_image'] = $upload_data['full_path'];
$config['new_image'] = $copy['dir'] . $upload_data['file_name'];
$config['maintain_ratio'] = TRUE;
$config['width'] = $copy['x'];
$config['height'] = $copy['y'];
$config['master_dim'] = 'width';
$this->image_lib->initialize($config);
$this->image_lib->resize();
}
Hope this helps!
You should just change the "upload_path" value in your configuration Array.
Here is some kind of code you could use :
$config['upload_path'] = './uploads/';
$this->load->library('upload', $config);
Referring to the User Guide :
