I am new to Codeigniter. Working on an form validation having image in the form. Using Module MVC extension in CodeIgniter.
//for upooading image I found this file upload snippet
$config['upload_path'] = './uploads/audio_files/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '2048';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload($file_name))
{
$error = array('error' => $this->upload->display_errors());
$file1 = '';
}
else
{
$upload_data = $this->upload->data();
$file1 = $upload_data['file_name'];
}
This is working fine. File which is not jpeg | gif is not uploaded. but user dont get any error message. I want the user to show that particular error when other image type is uploaded. Please help
I tried this but failed.
try 1 : $this->template->load_partial('admin/admin_master', 'admin/form', $error);
try 2. : loading view with $error
Thanks
Can't you associate a view with an error message? For instance:
After
$file1 = '';
You put:
$this->load->view('error_view', $error, $file1);
You would have to make a separate view page called 'error_view.php'.

error :- The filetype you are attempting to upload is not allowed
for those file types, just change your config of allowed_types into this to override checking extension:
$config['allowed_types'] = "*";
Before uploading your file, codeigniter check your file's extension first, but your file types are not in application/config/mimes.php so codeigniter does not know and then always return FALSE.
Another way is to add your mimes type into mimes.php, you can check out this in this link
I am developing a ad site that anyone able to upload 3 images.
So I am coding to upload that 3 images by adding timestamp in front of their file name to make them unique. I use codeigniter framework and attaching the code below.
when I submitting form data, localhost server shows that images have been saved correctly with some code infornt of image filename. But problem is there are no images saved in relevant image folder in that name and I cannot retrieve that images in next preview advertisement page.
I don't know much about php or codeignitor. Your help is highly appreciated.
$config['upload_path'] = './assets/images/adsimages';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 5120;
$this->load->library('upload',$config);
$this->upload->initialize($config);
if (!$this->upload->do_upload()){
$errors = array('error' => $this->upload->display_errors());
$post_image = 'no_image.jpg';
}
else {
$data = array('upload_data' => $this->upload->data());
$post_image1 = time().$_FILES['userfile1']['name'];
$post_image2 = time().$_FILES['userfile2']['name'];
$post_image3 = time().$_FILES['userfile3']['name'];
}
$result = $this->post_model->adregister($post_image1,$post_image2,$post_image3);
You can append time to 'filename' in config of upload library
$config['file_name'] = time().$_FILES['userfile1']['name'];
Or if you want unique name for all files the simply add
$config['encrypt_name'] = TRUE;
then
$this->load->library('upload', $config);
Try this one:-
$path = pathinfo($_FILES["userfile1"]["name"]);
$image_path = $path['filename'].'_'.time().'.'.$path['extension'];
I've written a possible solution for your code. You haven't shared your full code so you'll have to fill in the gaps yourself and maybe make some changes here and there; Comments are mentioned wherever necessary. See if it helps you.
public function your_function_name(){
// your-code
// your-code
// check if file is uploaded in field1
if(!empty($_FILES['userfile1']['name'])){
// call function to upload file
$userfile1 = $this->upload_file('userfile1');
}
// check if file is uploaded in field2
if(!empty($_FILES['userfile2']['name'])){
$userfile2 = $this->upload_file('userfile2');
}
// check if file is uploaded in field3
if(!empty($_FILES['userfile3']['name'])){
$userfile3 = $this->upload_file('userfile3');
}
$result = $this->post_model->adregister($userfile1, $userfile2, $userfile3);
}
// function to upload file
function upload_file($filename){
$config['file_name'] = time().$_FILES[$filename]['name']; // append time to filename
$config['upload_path'] = './assets/images/adsimages';
$config['allowed_types'] = 'gif|jpg|jpeg|png|GIF|JPG|PNG|JPEG';
$config['max_size'] = 5120;
$this->load->library('upload', $config);
$this->upload->initialize($config);
$uploaded = $this->upload->do_upload($filename);
if ( ! $uploaded ){
$error = array('error' => $this->upload->display_errors());
$file = 'no_image.jpg'; // default file
}else{
$upload_data = $this->upload->data();
$file = $upload_data['file_name']; // uploaded file name
}
return $file; // return filename
}
i am trying to upload an image in codigniter but unable to do so when I try it shows me an error array to string conversion
<?php
public function do_upload() {
$config['upload_path'] = base_url().'assets/uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
$this->upload->do_upload();
if (!$this->upload->do_upload()) {
$error = array('error' => $this->upload->display_errors());
$this->session->set_flashdata('success_msg', $error);
redirect('admin/theme');
} else {
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
?>
base_url() is return HTTP path not directory path, you should use directory path for upload content.
change
$config['upload_path'] = base_url().'assets/uploads/';
to
$config['upload_path'] = getcwd().'assets/uploads/';
you can use getcwd() native PHP function to get project root directory, and CI is also provides constant variable FCPATH for root directory.
Array to string conversion usually shows up, when you try to echo an Array.
so it seems, that the problem lies on this line:
echo validation_errors();
To avoid this error but still print out the values in the array use Foreach().
This Code should solve your problem:
foreach (validation_errors() as $error) {
//I assume you get an array as a return value
echo $error;
}
EDIT
This answer doesn't help anymore, as the author edited his question
You are uploding your files two time. After first uploding every thing is vanished and you have nothing to upload
$this->upload->do_upload();// first time
if (!$this->upload->do_upload()) {// second time
$error = array('error' => $this->upload->display_errors());
$this->session->set_flashdata('success_msg', $error);
redirect('admin/theme');
}
Just comment it
// $this->upload->do_upload();// comment this line
EDIT
You can send your message into set_flashdata() as
if (!$this->upload->do_upload('file_name')) {// add file name here
$error = $this->upload->display_errors();// remove array from here
$this->session->set_flashdata('success_msg', $error);
redirect('admin/theme');
}
To read a flashdata variable:
$this->session->flashdata('success_msg');
I am doing the following to upload a file(image) using codeigniter. What I am wanting to do is modify the error message so that it obvious which field the error relates too as there are multiple upload options on the page, below is my upload code,
$config['upload_path'] = './media/uploads/users';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1000';
$config['max_width'] = '90';
$config['max_height'] = '60';
$this->upload->initialize($config);
if(!$this->upload->do_upload('logo_small'))
{
$error = array('error' => $this->upload->display_errors());
$this->template->build('users/employer', $error);
}
else
{
$file = $this->upload->data();
$logo_small = "small_".$file['file_name'];
}
So basically I want there error message to state Logo Small in the error message, and then if the error relates to Logo large etc I would want it to state that.
easiest way is to edit system/language/english/upload_lang.php with the error message you want.
I have write below code :
function upld_logo()
{
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$data['msg']='Sorry! Cant Upload' . $error['error'];
$data['main_content']='message';
$this->load->view('template',$data);
}
else
{
//$data = array('upload_data' => $this->upload->data());
$names = $this->upload->data();
$k=$names['file_name'];
$data['msg']='Your Logo Successfully Uploaded. ';
$data['main_content']='message';
$this->load->view('template',$data);
}
}
When I upload Image file with name logo.gif it show error message :
The filetype you are attempting to upload is not allowed.
Find this code in your system->libraries->Upload.php line 200
$this->file_type = preg_replace("/^(.+?);.*$/", "\\1", $this->file_type);
and replace with this:
$this->file_type = preg_replace("/^(.+?);.*$/", "\\1", $_FILES[$field]['type']);
Yes I also got the same error.
And if u change the $[allowed_types] = "*" (allowed all files)
you will find that upload is success but your image file don't have a type!
I think there's something wrong with the CI library maybe?
I have spent some time with the same issue. You might find codeigniters default upload library is using a couple of deprecated PHP functions to find the files mime type.... Good luck, I'm still trying to patch it myself .
