delete from folder

[chris_s_22]

This is the code i use to upload a photo to a folder and put file name in database.

 

However if someone was to re use the form to change photo id like it so that the old one was deleted

How do i do this

 

<?php 
include 'Connect.php';

if(!isset($_POST[submit])) // checks that the data being recieved came from a POST variable named 'submit'  
{
   	 // if error reshow the form You cannot access this page directly.
   	 include 'index.php';
   	 exit;
}
else
{
if ((($_FILES["photo"]["type"] == "image/gif") 
|| ($_FILES["photo"]["type"] == "image/jpeg") 
|| ($_FILES["photo"]["type"] == "image/pjpeg"))
&& ($_FILES["photo"]["size"] < 51000))
{

	$ext = findexts ($_FILES['photo']['name']) ; //This applies the function to our file 
	$ran = rand () ;//This line assigns a random number to a variable.
	$ran2 = $ran."."; //adds a . on the end of $ran 
	$target = "images/"; //This is the directory where images will be saved
	$pic = $ran2.$ext;//This gets information from the form that has since been randomised and checked
	$target = $target . $ran2.$ext;//This combines the directory, the random file name, and the extension
	//If everything is ok we try to upload it 

	//Writes the information to the database 
	mysql_query("UPDATE members SET photo = '$pic' WHERE username = '$username'") ;
	if(move_uploaded_file($_FILES['photo']['tmp_name'], $target)) 
	{
	header('Location: index.php');   
	} 
	else 
	{ 
	echo "Sorry, there was a problem uploading your file."; 
	}  
}
else
{
echo "Invalid file";
}
}
?>
