php form upload and remane image then insert into DB - php

Question

I have a already functioning form that INSERT data into a db, i also have 4x file inputs for images, the form then adds all data, uplaods images and renames images to match the next ID and adds a random end to the filename.
this all works as intented
but i now need the filename(s) to be added to the database, sometimes the form will have 1x imaghe sometimes 4x images but im not sure how to store the filenames in the db from the below code. can anyone help? i assume the array needs to be broken down to individual filenames but not sure how to do it.
<?php
if(isset($_POST['submit'])){
// Variables for date&Time logs
$dateLog = date("y-m-d"); // DATE OF ADDITION
$timeLog = date("H:i:s", time() - 3600); // TIME OF ADDITION
// INSERT QUERY
$sql="INSERT INTO $table1 (firstname, lastname, companyname, phone, email, name, make, serial, catagory, price, location, description, sold, operational, year, clear, rip, version, service, dock, loading, available, extras, dateadded, featured)
VALUES ('$_POST[firstname]','$_POST[lastname]','$_POST[companyname]','$dateLog','No')";
$query = mysql_query($sql) or die("Cannot query the database.<br>" . mysql_error());
// start of image upload
$insert_id = mysql_insert_id() or die("Unable to get insert id for image name.<br>" . mysql_error());
extract($_POST);
$error=array();
$extension=array("jpeg","jpg","png","gif");
foreach($_FILES["files"]["tmp_name"] as $key=>$tmp_name)
{
$file_name=$_FILES["files"]["name"][$key];
$file_tmp=$_FILES["files"]["tmp_name"][$key];
$ext=pathinfo($file_name,PATHINFO_EXTENSION);
if(in_array($ext,$extension))
{
if(!file_exists("../images/listings/".$txtGalleryName."/".$file_name))
{
$filename=basename($file_name,$ext);
$newFileName=$insert_id."_".mt_rand(1, 99999).".".$ext;
move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"../images/listings/".$txtGalleryName."/".$newFileName);
}
else
{
$filename=basename($file_name,$ext);
$newFileName=$filename.mt_rand(1, 99999).".".$ext;
move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"../images/listings/".$txtGalleryName."/".$newFileName);
}
}
else
{
array_push($error,"$file_name, ");
}
}
// end of image upload
echo '<p>This item was added successfully</p>';
}
?>
and my form;
1: Upload : <input type="file" name="files[]"/><br />
2: Upload : <input type="file" name="files[]"/><br />
3: Upload : <input type="file" name="files[]"/><br />
4: Upload : <input type="file" name="files[]"/><br />
appreciate any help :)

Answer 1

you can use $rename_var = rand('111111','999999'); and prepend it before the file name like $new_changed_name = $rename_var.$_FILES['files']['name']; and then use this name while saving the file in folder like so .. move_uploaded_file('tmp_name','path/'.$new_changed_name);
and insert this $new_changed_name new name into database.
