PHP multiple uploads with PHP functions - php

Question

I try to understand how to use multiple uploads in PDO.
So I have my post.php:
$database = new Database();
$db = $database->getConnection();
$media = new Media($db);
if($_POST){
$image = !empty($_FILES["image"]["name"]) ? sha1_file($_FILES['image']['tmp_name']) . "-" . time() . "-" . basename($_FILES["image"]["name"]) : "";
$media->image = $image;
if ($media->create()) {
echo $media->uploadPhoto();
$_POST=array();
}
}
<input name="image[]" type="file" />
And my media.php with pdo query and some upload validations:
public $image;
public $created;
public function create(){
//write query
$query = "INSERT INTO " . $this->table_name . "
SET image=:image,
created=:created";
$stmt = $this->conn->prepare($query);
$this->image=htmlspecialchars(strip_tags($this->image));
$stmt->bindParam(":image", $this->image);
if($stmt->execute()){
return true;
}
print_r($stmt->errorInfo());
return false;
}
function uploadPhoto(){
$result_message="";
if(!empty($_FILES["image"]["tmp_name"])){
$target_directory = "../uploads/";
$target_file = $target_directory . $this->image;
$file_type = pathinfo($target_file, PATHINFO_EXTENSION);
$file_upload_error_messages="";
$check = getimagesize($_FILES["image"]["tmp_name"]);
if($check!==false){
}else{
$file_upload_error_messages.="<div></div>";
}
$allowed_file_types=array("jpg", "JPG", "jpeg", "JPEG", "png", "PNG", "gif", "GIF");
if(!in_array($file_type, $allowed_file_types)){
$file_upload_error_messages.="<div></div>";
}
if(file_exists($target_file)){
}
if($_FILES['image']['size'] > (10485760)){
$file_upload_error_messages.="<div></div>";
}
if(!is_dir($target_directory)){
mkdir($target_directory, 0777, true);
}
if(empty($file_upload_error_messages)){
if(move_uploaded_file($_FILES["image"]["tmp_name"], $target_file)){
}else{
$result_message.="<div></div>";
}
}
else{
$result_message.="{$file_upload_error_messages}";
}
}
return $result_message;
}
So I need to store the values in different mysql records and upload them all to the server.
What is the best way to do this and where to place the foreach?
I struggle with the right place of the foreach ...
$x=0;
foreach ( $_FILES['image']['name'] AS $key => $value ){
// ...
$x++;
}

Answer 1

so if this is your foreach loop and you want to insert different records for each uploaded file then use mysqli_multi_query
$x=0;
$query = "";
foreach ( $_FILES['image']['name'] AS $key => $value ){
$query .= 'insert into tableName (col1,col2,col3,image)VALUES("a","b","c","'.$value.'");';
$x++;
}
$query = rtrim($query,";");
mysqli_multi_query($connectionObj,$query);
Your query will look somthing like this
insert into tableName (col1,col2,col3,image)VALUES("a","b","c","a.jpg");
insert into tableName (col1,col2,col3,image)VALUES("a","b","c","b.jpg");
