How can i delete image files from uploaded folder in codeigniter from delete button??
Can any one guide me ???
Here is my controller that upload image files
private function upload() {
$config['upload_path'] = 'assets/uploads/orginal/';
$config['allowed_types'] = 'gif|jpg|png|jpeg|x-png';
$config['max_size'] = '500';
$config['max_width'] = '1600';
$config['max_height'] = '1200';
$config['remove_spaces'] = TRUE;
$this->load->library('upload', $config);
if ($this->upload->do_upload()) {
$img = $this->upload->data();
// create thumbnail
$new_image = 'assets/uploads/thumbs/' . $img['file_name'];
$c_img_lib = array(
'image_library' => 'gd2',
'source_image' => $img['full_path'],
'maintain_ratio' => TRUE,
'width' => 100,
'height' => 100,
'new_image' => $new_image
);
$this->load->library('image_lib', $c_img_lib);
$this->image_lib->resize();
} else {
$this->data['error'] = $this->upload->display_errors();
}
}
Use the unlink() function:
unlink($new_image);

if I try to enter data, it can enter the database, but it doesn't display
// GAMBAR

{

$gambar = $this->program_model->gambar($id_program);
// validasi input
$valid = $this->form_validation;
$valid->set_rules('judul_gambar', 'Judul/Nama Gambar', 'required',
array( 'required' => '%s harus diisi'));
if($valid->run()) {
$config['upload_path'] = './assets/upload/image/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';

$config['max_width'] = '3000';

if ( ! $this->upload->do_upload('gambar')) {
$data = array( 'title' => 'Tambah Gambar Program: '.$program->nama_program,
'program' => $program,
'gambar' => $gambar,

$config['new_image'] = './assets/upload/image/thumbs/';

$config['quality'] = "100%";
$config['maintain_ratio'] = TRUE;
$config['width'] = 360; // Pixel
$config['height'] = 360; // Pixel
$config['thumb_marker'] = '';
$this->load->library('image_lib', $config);
$this->image_lib->resize();
// end create gambar
$inp = $this->input;
$data = array( 'id_gambar' => $id_gambar,
'judul_gambar' => $inp->post('judul_gambar'),
'gambar' => $upload_data['uploads']['file_name'],
);
$this->program_model->tambah_gambar($data);
$this->session->set_flashdata('sukses', 'Data gambar telah ditambah');
redirect(base_url('admin/program/gambar/'.$id_program),'refresh');
}}
$data = array( 'title' => 'Tambah Gambar Program: '.$program->nama_program,
'program' => $program,
'gambar' => $gambar,
'isi' => 'admin/program/gambar'
);
$this->load->view('admin/layout/wrapper', $data, FALSE);
}
Is this working for you ?
'id_gambar' => $gambar["id_gambar"];
$id_gambar is not defined.
CodeIgniter upload class does is not returning the right full_path. I am trying to upload an image. I write up this code
$config['encrypt_name'] = TRUE;
echo $config['upload_path'] = FCPATH .'contest/videos/';
$config['max_size'] = '1000000000000000';
$config['allowed_types'] = '*';
$config['file_name'] = $_FILES['userfile']['name'];
$this->load->library('upload', $config);
$this->upload->initialize($config);
But it keeps asking that the permission denied. When I check the $this->upload->data() I see the full_path does not have last trailing slash after the last folder. See the print_r result
Array
(
[file_name] => testvdo.mp4
[file_type] =>
[file_path] => /var/www/html/zebra_1975/contest/videos
[full_path] => /var/www/html/zebra_1975/contest/videostestvdo.mp4
[raw_name] => testvdo.mp4
[orig_name] =>
[client_name] =>
[file_ext] =>
[file_size] =>
[is_image] =>
[image_width] =>
[image_height] =>
[image_type] =>
[image_size_str] =>
)
There should be a slash after video in full_path. What I am doing wrong here?
Try this I hope it will help you to set yours properly.
if (isset($_FILES['profile_img']) && !empty($_FILES['profile_img']['name']))
{
$user_img_path = './public/uploads/images/users/';
$config['upload_path'] = $user_img_path;
$config['allowed_types'] = 'gif|jpg|png';
$config['overwrite'] = TRUE;
$config['encrypt_name'] = TRUE;
$config['file_name'] = $img_name;
$config['max_size'] = '9999';
$config['max_width'] = '1524';
$config['max_height'] = '868';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('profile_img')){
$error = array('error' => $this->upload->display_errors());
print_r($error);
}
else{
$image = $this->upload->data();
print_r($image);
}
}
I am using this in my project
So for me I used this and is working for me
$user_img_path = './public/uploads/images/users/';
OR
$user_img_path = FCPATH'./public/uploads/images/users/';
OR
Editing Yours
$config['upload_path'] = FCPATH .'/contest/videos/';
Instead of
$user_img_path = FCPATH .'contest/videos/';
So try it. If it work for you let me know I am here to help

I'm uplaoding multiple images with CI, they do upload. I am also trying to resize them,
with the following code, only the first image resizes, rest of them don't. They get uploaded with their current size.
What's wrong?
Any help'd be really, really appreciated.
function doupload() {
$path = array();
$count = count($_FILES['userfile']['size']);
foreach($_FILES as $key=>$value){
for($n=0; $n<=$count-1; $n++) {
$_FILES['userfile']['name']=$value['name'][$n];
$_FILES['userfile']['type'] = $value['type'][$n];
$_FILES['userfile']['tmp_name'] = $value['tmp_name'][$n];
$_FILES['userfile']['error'] = $value['error'][$n];
$_FILES['userfile']['size'] = $value['size'][$n];
$config['upload_path'] = './images';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
$this->upload->do_upload();
$data = $this->upload->data();
$path[] = $data['full_path']; //contains full path of every image
}
}
foreach($path as $p=>$ath){
$config1 = array(
'source_image' => $ath,
'new_image' => './images',
'maintain_ration' => true,
'overwrite' => true,
'width' => 600,
'height' => 400
);
$this->load->library('image_lib', $config1);
$this->image_lib->resize();
$this->image_lib->clear();
}
}
first load image_lib outside loop you can use initialize in loop and pass new config for every image
$this->load->library('image_lib');
foreach($path as $p=>$ath){
$config1 = array(
'source_image' => $ath,
'new_image' => './images',
'maintain_ration' => true,
'overwrite' => true,
'width' => 600,
'height' => 400
);
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
}
CodeIgniter's Loader class loads libraries only once, so in your foreach you resize the same image multiple times. Move the library loading out of the loop and use the initialize method of Image Manipulation library to set the config for every resize.
in my case load lib in constructor and use code
$config['image_library'] = 'gd2';
$config['maintain_ratio'] = FALSE;
$config['source_image'] = $config['upload_path'].$image_info['file_name'];
$config['new_image'] = $config['upload_path']."thumb_".$image_info['file_name'];
$config['width'] = 313;
$config['height'] = 303;
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
$config['new_image'] = $config['upload_path']."icon_".$image_info['file_name'];
$config['width'] = 70;
$config['height'] = 70;
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->image_lib->clear();
keep index name always new_image in $config['new_image']
