PHP/MySQL - Data entered twice when doing single upload - php

Question

I am trying to upload image to database MySQL. But I have a problem, when I am trying to upload one image, the image inserted twice.
For example:
I have "A.jpg" if I try to upload it
the inserted data will be like "A.jpg,A.jpg"
What I want in database "A.jpg"
and if I try to upload multiple images like "A.jpg,B.jpg and C.jpg"
the inserted data will be like "B.jpg,B.jpg,C.jpg,C.jpg"
What I want in database "A.jpg,B.jpg,C.jpg"
I've tried to search on google but no results, anyone can help me to resolve this problem ? Thanks
Here is my code :
include('koneksi.php');
date_default_timezone_set('Asia/Jakarta');
$id_user = $_POST['id_user'];
$caption = $_POST['caption'];
$files = [];
foreach($_FILES['files']['name'] as $i => $name) {
$name = $_FILES['files']['name'][$i];
$size = $_FILES['files']['size'][$i];
$type = $_FILES['files']['type'][$i];
$tmp = $_FILES['files']['tmp_name'][$i];
$explode = explode('.', $name);
$ext = end($explode);
$updatdName = $explode[0] . time() .'.'. $ext;
$path = 'gallery/';
$path = $path . basename( $updatdName );
if(empty($_FILES['files']['tmp_name'][$i])) {
$errors[] = 'Please choose at least 1 file to be uploaded.';
}else {
$allowed = array('jpg','JPG','jpeg','JPEG','gif','GIF','bmp','BMP','png','PNG');
$max_file_size = 1024*1024*2;; // 2MB
if(in_array($ext, $allowed) === false) {
$errors[] = 'The file <b>'.$name.'</b> extension is not allowed.';
}
if($size > $max_file_size) {
$errors[] = 'The file <b>'.$name.'</b> size is too hight.';
}
}
if(empty($errors)) {
// if there is no error then set values
$files['file_name'][] = $updatdName;
$files['size'][] = $size;
$files['type'][] = $type;
$errors = array();
if(!file_exists('gallery')) {
mkdir('gallery', 0777);
}
if(move_uploaded_file($tmp, $path)) {
echo '<script>window.history.back()</script>';
}else {
echo 'Something went wrong while uploading
<b>'.$name.'</b>';
}
}else {
foreach($errors as $error) {
echo '<p>'.$error.'<p>';
}
}
}
if(!empty($files)) {
$files['file_name'][] = $updatdName;
$files['size'][] = $size;
$files['type'][] = $type;
$names = implode(',', $files['file_name']);
$sizes = implode(',', $files['size']);
$types = implode(',', $files['type']);
$sql="INSERT into status VALUES(NULL, '$id_user', '$names','$caption','foto',NOW()); ";
mysqli_query($koneksi, $sql);
}

You're setting $files['file_name'][] in the while loop and also right before inserting into the DB. You just need to remove 2nd call to $files['file_name'][] = $updatdName;
Here is a simplified version of what you're doing.
<?php
$_FILES[] = ['name' => 'A'];
$_FILES[] = ['name' => 'B'];
$_FILES[] = ['name' => 'C'];
$files = [];
foreach ($_FILES as $file) {
$updatdName = $file['name'];
// You're setting it here
$files['file_name'][] = $updatdName;
}
if (!empty($files)) {
// And also here.
$files['file_name'][] = $updatdName;
$names = implode(',', $files['file_name']);
echo $names;
}
