PHP multipart/form Data - php

Question

I'm trying to upload a file , but file name is a variable,so to do that I have get the name of input type(i can do it by getting all data on post and run a loop and get the keyname)
then I'm getting all post data , but then it returns me a empty array,when I remove multipart/form data from the form it will return the array with the value.then I can get the file type name, but it doesn't upload the file because I remove the multipart from the form.
How can I do this? if read the code u will understand. Please help me to do this.
This is my view page
public function addTest($app_id)
{
$data=$this->input->post();
$id=$this->session->userdata['loggedHospitalData']['hp_id'];
while ($test = current($data)) {
$dataArr=array(
"hospital_id" => $id,
);
$test_id=key($data);
$wherArr = array("test_id"=>$test_id);
//$result = $this->Hospital_model->updateTestData($dataArr,$wherArr);
$report=$this->input->post($test_id);
$config['upload_path'] = './uploads/';
$config['allowed_types'] = '*';
$config['max_size'] = 5000000000000;
$config['max_width'] = 10240;
$config['max_height'] = 10240;
$this->load->library('upload', $config);
if (!$this->upload->do_upload($report))
{
$error = array('error' => $this->upload->display_errors());
}
else
{
$data1 = array('upload_data' => $this->upload->data());
}
/*$dataRepArr=array(
"r_test_id " => $test_id,
"file" => $photo1,
);*/
next($data);
//header('Location: http://localhost/docto/index.php/Hospital/patientView/'.$app_id);
}
}
And this my View
<form action="<?php echo base_url(); ?>index.php/Hospital/addTest/<?php echo $appoinmentData->app_id; ?>" role="form" method='post' onmouseover="return form_validate()" name="vform">
<div class="">
<ul class="to_do">
<?php
foreach ($testData as $test) {
echo '
<li>
<p>
'.$test->test_name.' </p>
</br>
<input type="file" class="btn btn-primary" name="'.$test->test_id.'">
</li>
';
}
?>
</ul>
</div>
<input type="submit" class="btn btn-success btn-lg btn-block" value="Update" name="">
</form>

Answer 1

You need multipart/form-data for the rules to be uploaded. Put it back.
Then loop over $_FILES to get all the files that were uploaded.

Answer 2

multipart/form-data MUST be there for file uploads
You can try something like this:
$this->load->library('upload');
$config['upload_path'] = './assets/uploads/'
$config['allowed_types'] = 'jpg|png|jpeg|pdf';
$config['max_size'] = '0';
$config['overwrite'] = TRUE;
$config['encrypt_name'] = TRUE;
$this->upload->initialize($config);
foreach($_FILES as $k => $v)
{
if ($_FILES[$k]['name'] != '')
{
//This do the trick, do_upload need the name of the input
//And in this case, name is the KEY of an array.
if($this->upload->do_upload($k))
{
//Upload Successful
}
}
}
