I am trying to upload a csv file after then the file data will be print/insert.But my code is not printing the data according to my code.It is printing Id: Marks complete 1.But my file is uploading.
my input csv file format is
Id,Marks
20,46
20,46
32,45
My controller code is
public function upload_marks(){
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'csv';
$config['max_size'] = '10000';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('marksfile'))
{
echo $this->upload->display_errors();
}
else
{
$uploadData = $this->upload->data();
$fileName = $uploadData['file_name'];
$this->load->library('csvreader');
$csvData = $this->csvreader->parse_file('./uploads/',$fileName);
foreach($csvData as $data){
echo " ID: ".$data['id'];
echo " Marks: ".$data['marks'];
}
echo " Complete 1";
}
}
Where is the problem ? Could you get my error ?
Suppose your data is in B1,B2,B3,B4 position for your excell sheet, Then code as given below with phpexcel library.
$uploadData = $this->upload->data();
$fileName = $uploadData['file_name'];
$this->load->library('excel');
$objReader = PHPExcel_IOFactory::createReader('Excel5');
$objPHPExcel = $objReader->load('./uploads/'.$fileName);
$sheetData = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
$prof = $objPHPExcel->getActiveSheet()->getCell('B1')->getValue();
$term = $objPHPExcel->getActiveSheet()->getCell('B2')->getValue();
$sbjCode = $objPHPExcel->getActiveSheet()->getCell('B3')->getValue();
$year = $objPHPExcel->getActiveSheet()->getCell('B4')->getValue();
After then code as above for your rest data according to position. Hope this will works .
Use PHPExcel Library it works fantastic, I have used same in various projects.

I want to upload multiple photos but when I create an uniqid, the photos look the same uniqid. How can I get around this?
for($i=0;$i<$countfiles;$i++){
$_FILES['files']['name'] = $files['galeri']['name'][$i];
$_FILES['files']['type'] = $files['galeri']['type'][$i];
$_FILES['files']['tmp_name'] = $files['galeri']['tmp_name'][$i];
$_FILES['files']['error'] = $files['galeri']['error'][$i];
$_FILES['files']['size'] = $files['galeri']['size'][$i];
$config['upload_path'] = "uploads/urunler/galeri/";
$config["allowed_types"] = "jpg|jpeg|png";
$config['max_size'] = '5000';
$config['file_name'] = uniqid().$_FILES['files']['name'];
$this->load->library('upload', $config);
if($this->upload->do_upload('files')){
$uploadData = $this->upload->data();
$filename = $uploadData['file_name'];
$galeri_arr['filenames'][] = $filename;
}
}
Result:
{
0: "5f6fd81e54f1bimg52.jpg",
1: "5f6fd81e54f1bimg521.jpg"
}
For generate unique file name best way is use timestamp in file name with uniqid().
$config['file_name'] = uniqid().time().$_FILES['files']['name'];
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've been trying to upload an image to my database (Note: I'm using Codeigniter 3) but every time I try to upload the image to the database it doesn't store it's filename and the image itself and only stores 1 bit in BLOB var type.
$photo = file_get_contents($_FILES['image']['tmp_name];
this->db->select('*')
[...]
if(empty($response){
$data['entry_phone_no'] = $this->input->post('phone_no');
$data['entry_email'] = $this->input->post('email');
$data['entry_firstname'] = $this->input->post('first_name');
$data['entry_lastname'] = $this->input->post('last_name');
$data['entry_photo'] = $photo;
$data['entry_photo_name'] = $photo;
In my model.php I have the setup above and it saves the other data (the phone num, email etc). I know I am missing some code at the "$photo" part but can anyone please point it out?
You can upload the image on folder called "Uploads" and save that filename into database as below:
Views.php:
<input class="my-set_3" type="file" name="chatbot_profile" id="chatbot_profile" required>
Controller.php:
if (!empty($_FILES['chatbot_profile']['name']))
{
$config['upload_path'] = './uploads';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 1000000;
$config['file_name'] = time();
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('chatbot_profile'))
{
$error = array('error' => $this->upload->display_errors());
}
else
{
$data = array('upload_data' => $this->upload->data());
$file_name = $data['upload_data']['file_name'] ;
// Store this filename into database
// Your database code will be placed here
// OR call model mathod from here
}
}
Note: uploads folder will created by us and outside the application
folder.
I am trying to upload image using code-igniter, but it's not possible, why I don't know. Can anyone help me?
Here is code I have tried
public function upload(){
$config['upload_path'] = "./assets/uploads/";
$config['allowed_types'] = "jpg|png|jpeg|gif";
$this->load->library("upload" , $config);
$rs = $this->upload->do_upload("userfile");
print_r($rs);
print_r($_FILES);
if(!$rs){
$error = array('error'=>$this->upload->display_errors());
$this->load->view("main_view", $error);
}
else{
$file_data = $this->upload->data(); $data['img'] = "localhost/FileUpload/assets/uploads/";
$file_data['file_name']; $this->load->view("success_msg" , $data);
}
}
I'm not able to actually test this of course, but I believe this will get you started.
public function upload() {
$name = 'something'; // set this based on your requirements, I often use random strings or user names according to the situation.
$config['upload_path'] = "assets/uploads/";
$config['allowed_types'] = "jpg|png|jpeg|gif";
$config['file_name'] = $name;
$this->load->library("upload" , $config);
$rs = $this->upload->do_upload("userfile");
print_r($rs);
print_r($_FILES);
if(!$rs) {
$error = array( 'error'=>$this->upload->display_errors() );
$this->load->view("main_view", $error);
}
else {
$file_data = $this->upload->data();
$file_name = $file_data['file_name'];
$ext = pathinfo($file_name, PATHINFO_EXTENSION); //Useful to store your name in database if/when you need to
$data = array('upload_data' => $upload_data);
$this->load->view("success_msg" , $data);
}
}
I am uploading multiple dynamic images with codeigniter with the following code.
foreach ($_FILES as $key => $value) {
$imagePrefix = time();
if (!$this->upload->do_upload($key))
{
echo $errors = $this->upload->display_errors();
return '';
}
else
{
$imagename = $imagePrefix.$value['name'];
$insertImage = $this->db->query("Insert into `tbl_event_imges` (`iEventID`,`vImage`) values ('".$insertId."','".$imagename."')");
}
}
When I upload an image to the specific folder this works fine; the issue is if a user uploads an image having same name, then it will automatically rename the image and upload to the folder, but what I want is to rename it by adding $imagePrefix that I have added in else part of the code and then want to upload the image with this name. But this is not working with me..
Any suggestion please?
you need to provide configuration preferences to your upload function like so:
$imagePrefix = time();
$imagename = $imagePrefix.$value['name'];
$this->load->library('upload');
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['file_name'] = $imagename; // set the name here
$this->upload->initialize($config);
if (!$this->upload->do_upload($key)){
...
}else{
...
}
Source: http://www.codeigniter.com/user_guide/libraries/file_uploading.html?highlight=file%20upload#setting-preferences
Just alternative, you can use CI's rename function to rename after file uploaded.
$image = $this->upload->data();
$file_path = $image ['file_path'];
$file = $image ['full_path'];
$file_ext = $image['file_ext'];
$final_file_name = time() . $image['file_name'] . $file_ext;
only add below code and it run successfully and also set encrypt_name to false
$path = $_FILES['userfile']['name'];
$newName = "Add any name".".".pathinfo($path, PATHINFO_EXTENSION);
$config['file_name'] = $newName;
$config['encrypt_name'] = false;
