Rename File Name During Uploading - php

Question

$uniqId = $this->input->post('U_I_T_Roll_No');
$config['upload_path'] = "./uploads/ProfileImages/";
$config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
$config['max_size'] = '1024';
$config['max_width'] = '1000';
$config['max_height'] = '1000';
/* Load the upload library */
$this->load->library('upload', $config);
/* Create the config for image library */
/* (pretty self-explanatory) */
$configThumb = array();
$configThumb['image_library'] = 'gd2';
$configThumb['source_image'] = '';
$configThumb['create_thumb'] = FALSE;
$configThumb['maintain_ratio'] = TRUE;
/* Set the height and width or thumbs */
/* Do not worry - CI is pretty smart in resizing */
/* It will create the largest thumb that can fit in those dimensions */
/* Thumbs will be saved in same upload dir but with a _thumb suffix */
/* e.g. 'image.jpg' thumb would be called 'image_thumb.jpg' */
$configThumb['width'] = 400;
$configThumb['height'] = 400;
/* Load the image library */
$this->load->library('image_lib');
/* We have 5 files to upload
* If you want more - change the 6 below as needed
*/
for($i = 1; $i < 5; $i++) {
/* Handle the file upload */
$upload = $this->upload->do_upload('image'.$i);
/* File failed to upload - continue */
if($upload === FALSE) continue;
/* Get the data about the file */
$data = $this->upload->data();
$uploadedFiles[$i] = $data;
/* If the file is an image - create a thumbnail */
if($data['is_image'] == 1) {
$configThumb['source_image'] = $data['full_path'];
$this->image_lib->initialize($configThumb);
$this->image_lib->resize();
}
}
$S_image = $_FILES['image1']['name'];
$F_image = $_FILES['image2']['name'];
$M_image = $_FILES['image3']['name'];
$LG_image = $_FILES['image4']['name'];
$data5=array (
'Uniq_Id' => $this->input->post('U_I_T_Roll_No'),
'S_image' => $S_image,
'F_image' => $F_image,
'M_image' => $M_image,
'LG_unique1' => $LG_image,
);
$this->InsertData->studentimageupload($data5);
The Above code Works Fine. I Have 4 Image to Upload and Uploading properly and the name of image saving into database. the problem is the.
I want to Upload image name according to me and save name of the image into database.
Like : S$uniqId, F$uniqId, M$uniqId, LG$uniqId

Answer 1

Do something like this before $this->load->library('upload', $config);
Change $this->load->library('upload', $config); to $this->load->library('upload'); and see below
for($i = 1; $i < 5; $i++) {
$img=$_FILES['image'.$i]['name'];
$new_name=NEW_NAME;
$ext = strtolower(substr($img, strpos($img,'.'), strlen($img)-1));
$file_name=$new_name.$ext;
$config['file_name'] = $file_name;
$this->upload->initialize($config);
/* Handle the file upload */
$upload = $this->upload->do_upload('image'.$i);
/* File failed to upload - continue */
if($upload === FALSE) continue;
/* Get the data about the file */
$data = $this->upload->data();
$uploadedFiles[$i] = $data;
/* If the file is an image - create a thumbnail */
if($data['is_image'] == 1) {
$configThumb['source_image'] = $data['full_path'];
$this->image_lib->initialize($configThumb);
$this->image_lib->resize();
}
}

Answer 2

The name used is whatever is present in $_FILES['image1']['name']. If you want to change it, you can change it in the upload form itself. If that is not desirable, you have to call rename() and then update
$S_image = $_FILES['image1']['name'];
$F_image = $_FILES['image2']['name'];
$M_image = $_FILES['image3']['name'];
$LG_image = $_FILES['image4']['name'];
to whatever you have renamed the files to, before storing in database.

Answer 3

I think you can solve the renaming problem by initializing the config each time when you call the do_upload method.
$config['file_name'] = YOUR_OWN_NAME
and then Initialize in your for loop, Just before your do_upload call
$this->upload->initialize($config);

Answer 4

You should be able to specify the 'file_name' after loading the library & right before uploading the file..
//make your config array.
$this->load->library('upload', $config);
for($i=1; $i < 5; $i++)
{
$this->upload->set_filename($path, $filename);
$upload = $this->upload->do_upload('image'. $i);
//do whatever you want to do with the file.
}
I've not used it in any of my projects so far, but it should produce the desired result. Just let me know, if it doesn't work..
