How to store file path using PHP file upload

Question

I have a file upload code. I face some problem. I want to save file path in database which is uploaded by user but I failed in it. Can you please help me.

Here is my code

<?php
$host="localhost"; // Host name 
$username="root"; // Mysql username 
$password=""; // Mysql password 
$db_name="test123"; // Database name 
//$tbl_name="members"; // Table name 
$con=mysql_connect("localhost","root","");
if(! $con)
{
die('Connection Failed'.mysql_error());
}
mysql_select_db("test123",$con);

if(isset($_FILES['files'])){
    $errors= array();
    foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
        $file_name = $key.$_FILES['files']['name'][$key];
        $file_size =$_FILES['files']['size'][$key];
        $file_tmp =$_FILES['files']['tmp_name'][$key];
        $file_type=$_FILES['files']['type'][$key];
        $file_path=$_FILES['files']['path'][$key];  
        if($file_size > 2097152){
            $errors[]='File size must be less than 2 MB';
        }       
        $query="INSERT into upload(`FILE_NAME`,`FILE_SIZE`,`FILE_TYPE`,`FILE_PATH`) VALUES('$file_name','$file_size','$file_type', '$file_path'); ";
$desired_dir="user_data";
        //$desired_dir=$options['upload_dir']."user_data";
        if(empty($errors)==true){
            if(is_dir($desired_dir)==false){
                mkdir("$desired_dir", 755);     // Create directory if it does not exist
            }
            if(is_dir("$desired_dir/".$file_name)==false){
                move_uploaded_file($file_tmp,"$desired_dir/".$file_name);
            }else{                                  // rename the file if another one exist
                $new_dir="$desired_dir/".$file_name.time();
                 rename($file_tmp,$new_dir) ;               
            }
         mysql_query($query);           
        }else{
                print_r($errors);
        }
    }
    if(empty($error)){
        echo "Success";
    }
}
?>

You should try something like this :

<?php
$host="localhost"; // Host name
$username="root"; // Mysql username
$password="root"; // Mysql password
$db_name="test"; // Database name
//$tbl_name="members"; // Table name
$con=mysql_connect("localhost","root","");
if(! $con)
{
    die('Connection Failed'.mysql_error());
}
mysql_select_db("test123",$con);

if(isset($_FILES['files'])){
    $errors= array();
    foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
        $file_name = $key.$_FILES['files']['name'][$key];
        $file_size =$_FILES['files']['size'][$key];
        $file_tmp =$_FILES['files']['tmp_name'][$key];
        $file_type=$_FILES['files']['type'][$key];
        $file_path=$_FILES['files']['path'][$key];
        if($file_size > 2097152){
            $errors[]='File size must be less than 2 MB';
        }

        //$desired_dir=$options['upload_dir']."user_data";
        $desired_dir="user_data";
        if(empty($errors)==true)
        {
            if(is_dir($desired_dir)==false){
                mkdir("$desired_dir", 755);     // Create directory if it does not exist
            }

            $file_path_name = "$desired_dir/".$file_name;

            if(is_dir("$desired_dir/".$file_name)==false){
                move_uploaded_file($file_tmp,"$desired_dir/".$file_name);
            }else{                                  // rename the file if another one exist
                $new_dir="$desired_dir/".$file_name.time();
                rename($file_tmp,$new_dir) ;
            }

            $query="INSERT into upload(`FILE_NAME`,`FILE_SIZE`,`FILE_TYPE`,`FILE_PATH`) VALUES('$file_name','$file_size','$file_type', '$file_path_name'); ";
            mysql_query($query);
        }else{
            print_r($errors);
        }
    }
    if(empty($error)){
        echo "Success";
    }
}
?>

Usually when I'm doing this, I'll just store the exact file name (the name given to the file after it has been moved to the desired location) to the database. Then when I want to retrieve I just append the file name to the file path.

Like:

<img src = "/user_data/<?php echo ($file_name); ?>.png";

Reasons:

1. Storing the slashes and extensions can make the database messy. (Personal Preference).

2. By default the user_data folder is always going to be available so why not reference to it directly in order to make my codes more readable.
