Codeigniter multiple files uploads per field with input array key - php

Question

I have here multiple fields with multiple files uploads with array key name. I need to uploads multiple files per field and pass the filenames in array with keys into the model.
I really need this, hoping for someone would help me.
Thanks.
Here's the example of my fields
//with 2 or more files
<input accept="application/pdf" name="vtc_file[0]" id="vtc_file0" type="file" multiple/>
//with 2 or more files
<input accept="application/pdf" name="vtc_file[1]" id="vtc_file1" type="file" multiple/>
<?php
$count = count($_FILES['vtc_file']['name']);
for ($i=0; $i < $count; $i++)
{
foreach ($_FILES['vtc_file'] as $key1 => $value1)
{
foreach ($value1 as $key2 => $value2)
{
$files[$key2][$key1] = $value2;
}
}
}
$_FILES = $files;
$document_config['upload_path'] = 'uploads/';
$document_config['allowed_types'] = 'pdf';
$this->load->library('upload', $document_config);
foreach ($_FILES as $fieldname => $fileObject)
{
if (!empty($fileObject['name']))
{
$this->upload->initialize($document_config);
if (!$this->upload->do_upload($fieldname))
{
$errors = $this->upload->display_errors();
}
else
{
$results = $this->models->save();
}
}
}

I've made a demo for you, I've explained the steps in the code itself. Hope it works for you.
View
<form action="<?Php echo base_url('home/myfunc'); ?>" method="POST" enctype="multipart/form-data">
<!-- You need to make an array of input fields(See {name}) -->
<input accept="application/pdf" name="vtc_file[0][]" id="vtc_file0" type="file" multiple/>
<!-- If the usdr uploads only one file it will be stored like vtc_file[0][1] = 'filename.pdf' and so on.-->
<br>
<input accept="application/pdf" name="vtc_file[1][]" id="vtc_file1" type="file" multiple/><br>
<button type="submit" value="submit">Submit</button>
</form>
Controller
function myfunc(){
// check if the $_FILES is not empty(your validation here) then perform these actions↓↓
foreach ($_FILES['vtc_file']['name'] as $key1 => $value1){ // We only need to loop through all the input fields(vtc_file)
foreach ($value1 as $key2 => $value2){ // loop through name of all the files uploaded
// Make a new dummy element(userfile) with the file(vtc_file') details in it
$_FILES['userfile']['name'] = $_FILES['vtc_file']['name'][$key1][$key2];
$_FILES['userfile']['type'] = $_FILES['vtc_file']['type'][$key1][$key2];
$_FILES['userfile']['tmp_name'] = $_FILES['vtc_file']['tmp_name'][$key1][$key2];
$_FILES['userfile']['error'] = $_FILES['vtc_file']['error'][$key1][$key2];
$_FILES['userfile']['size'] = $_FILES['vtc_file']['size'][$key1][$key2];
$config['upload_path'] = './uploads/aaa'; // path to the folder
$config['allowed_types'] = 'pdf';
$config['max_size'] = 1000;
// $config['max_width'] = 1024;
// $config['max_height'] = 768;
$this->load->library('upload', $config); // load the {upload} library
$this->upload->initialize($config); // initialize the library
if (!$this->upload->do_upload("userfile")){ // upload the file(current)
$data['errors'][$key1][$key2] = $this->upload->display_errors(); // if any error store them in {errors} variable with keys
}else{
$upload_data = $this->upload->data(); // get the uploaded file data
$data['filename'][$key1][$key2] = $upload_data['file_name']; // store the upload file name in {filename} variable with keys
}
}
}
//load model {event_model}
$this->load->model('event_model');
$success = $this->event_model->save_file($data['filename']); // call model function
// check if query successful
if($success){
// do something (Load a view)
// You can show uploaded files in your view with $data['filename'][$key1][$key2]
// And the errors of files that couldn't be uploaded with $data['errors'][$key1][$key2]
echo '<pre>'; print_r($data['errors']);
}else{
// do something else
}
}
Model
function save_file($data){
echo '<pre>'; print_r($data);
// Your insert query here.
return true;
}
Output:
Model: $filename array
Array
(
[0] => Array
(
[0] => Account_Software______Payment.pdf
[1] => Account_Software______RTGS_Report.pdf
)
[1] => Array
(
[0] => BUSINESS_PROFILE.pdf
)
)
Controller: $errors array
Array
(
[1] => Array
(
[1] =>
The filetype you are attempting to upload is not allowed.
)
