Codeigniter File Upload Permit Only For Images not For Others - php

Question

I have to file upload operation consecutive, first for images like gif|jpg|jpeg|png|svg and the second psd|rar|zip|doc|word|txt|xlsx|pdf
First one is working just fine, i can upload all images but the second, i can not upload any of these types but when i try to upload image on second segment it works.
if (isset($_FILES['content_images']['name'])) {
$count_files = count($_FILES['content_images']['name']);
for ($i = 0; $i < $count_files; $i++) {
$_FILES['image']['name'] = $_FILES['content_images']['name'][$i];
$_FILES['image']['type'] = $_FILES['content_images']['type'][$i];
$_FILES['image']['tmp_name'] = $_FILES['content_images']['tmp_name'][$i];
$_FILES['image']['error'] = $_FILES['content_images']['error'][$i];
$_FILES['image']['size'] = $_FILES['content_images']['size'][$i];
$config_images['upload_path'] = "./public/site/images/contents";
$config_images['allowed_types'] = 'gif|jpg|jpeg|png|svg';
$config_images['max_size'] = 5000;
$config_images['max_width'] = 7680;
$config_images['max_height'] = 4320;
$this->load->library("upload", $config_images);
if (!$this->upload->do_upload('image')) {
echo $this->upload->display_errors();
exit;
} else {
$data = $this->upload->data();
$path_images[] = "public/site/images/contents/".$data['file_name'];
}
}
}
if (isset($_FILES['content_files']['name'])) {
$count_files=count($_FILES['content_files']['name']);
for ($i = 0; $i < $count_files; $i++) {
$_FILES['file']['name'] = $_FILES['content_files']['name'][$i];
$_FILES['file']['type'] = $_FILES['content_files']['type'][$i];
$_FILES['file']['tmp_name'] = $_FILES['content_files']['tmp_name'][$i];
$_FILES['file']['error'] = $_FILES['content_files']['error'][$i];
$_FILES['file']['size'] = $_FILES['content_files']['size'][$i];
$config_files['upload_path'] = "./public/site/files/contents";
$config_files['allowed_types'] = 'psd|rar|zip|doc|word|txt|xlsx|pdf';
$config_files['max_size'] = 5000;
$config_files['max_width'] = 7680;
$config_files['max_height'] = 4320;
$this->load->library("upload",$config_files);
if (!$this->upload->do_upload('file')) {
foreach($path_images as $p){
unlink($p);
}
echo $this->upload->display_errors();
exit;
} else {
$data=$this->upload->data();
$path_files[] = "public/site/files/contents/".$data['file_name'];
}
}

I found the solution
For help :
You should load the library at the top for 1 time only, and then u should initialize it inside 'if condition'.
When you load upload library and config array inside first condition, when you pass to second condition upload library had already loaded and uses the first condition's config array.
$this->load->library("upload");
if(isset($_FILES['content_images']['name'])){
$count_files=count($_FILES['content_images']['name']);
for($i = 0;$i<$count_files;$i++){
$_FILES['image']['name'] = $_FILES['content_images']['name'][$i];
$_FILES['image']['type'] = $_FILES['content_images']['type'][$i];
$_FILES['image']['tmp_name'] = $_FILES['content_images']['tmp_name'][$i];
$_FILES['image']['error'] = $_FILES['content_images']['error'][$i];
$_FILES['image']['size'] = $_FILES['content_images']['size'][$i];
$config_images['upload_path'] = "./public/site/images/contents";
$config_images['allowed_types'] = 'gif|jpg|jpeg|png|svg';
$config_images['max_size'] = 5000;
$config_images['max_width'] = 7680;
$config_images['max_height'] = 4320;
$this->upload->initialize($config_images);
if(!$this->upload->do_upload('image')){
echo $this->upload->display_errors();
exit;
}else{
$data=$this->upload->data();
$path_images[] = "public/site/images/contents/".$data['file_name'];
}
