this is my present upload script

<?php 
 $correctAnswer = 4; if($_POST['leg'] != $correctAnswer) { 
    // send em away 
    header("Location: http://www.lostpetsplymouth.com/error-page.html"); 
    exit(); 
}
//This is the directory where images will be saved 
$target = "uploads/"; 
$target = $target . basename( $_FILES['photo']['name']); 

//This gets all the other information from the form 
$state=$_POST['state']; 
$type=$_POST['type'];
$area=$_POST['area'];
$desc=$_POST['desc'];
$name=$_POST['name'];
$email=$_POST['email'];
$tel=$_POST['tel'];
$date = date("d-m-Y");
$pname=($_FILES['photo']['name']); 
// Connects to your Database 
 $dbh=mysql_connect("localhost", "vcd", "57") or die('I cannot connect to database because: ' .mysql_error()) ; 
mysql_select_db("pets"); 

//Writes the information to the database 
mysql_query("INSERT INTO `register` VALUES ('$id', '$state', '$type', '$area', '$desc', '$name', '$email', '$tel', '$pname', '$date')");
//Writes the photo to the server 
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target)) 
{ 

//Tells you if its all ok 
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory"; 
} 
else { 

//Gives and error if its not 
echo "Sorry, there was a problem uploading your file."; 
}  
//send the mail       
mail('doug@.com','New Record',$msg)

?> 

<?php
echo "your Report has now been added, You will be redirected in three seconds!><br /><br /> 

		<div class='info'>If you don't wish to wait, <a href='index.html'>click here</a>";			
		echo'<meta http-equiv="REFRESH" content="2;url=index.html">';
?>					

PHP:

and this is the script i found and want to incorparate

<?php
//This function separates the extension from the rest of the file name and returns it 
function findexts ($filename) 
{ 
$filename = strtolower($filename) ; 
$exts = split("[/\\.]", $filename) ; 
$n = count($exts)-1; 
$exts = $exts[$n]; 
return $exts; 
} 

//This applies the function to our file 
$ext = findexts ($_FILES['uploaded']['name']) ; 
//This line assigns a random number to a variable. You could also use a timestamp here if you prefer. 
$ran = rand () ;

//This takes the random number (or timestamp) you generated and adds a . on the end, so it is ready of the file extension to be appended.
$ran2 = $ran.".";

//This assigns the subdirectory you want to save into... make sure it exists!
$target = "uploads/";
//This combines the directory, the random file name, and the extension
$target = $target . $ran2.$ext

PHP:

 

Just use rand(), and .=

$example = "blah";
$rand1 = rand(1, 1000);
$example .= $rand1;

Code (markup):

This would add a random number from 1 to 1000 at the end of blah.. blah being an example of an image upload name.

 

thanks for reply but where do i put that bit of code
cheers

You can just add the upload time in unix format to your file name, and you should be fine.
To do that just change this line of your code:

$target = $target . basename( $_FILES['photo']['name']);

PHP:

To:

$target = $target .time().'_'.basename( $_FILES['photo']['name']);

PHP:

 

ok thanks that worked for renameing the photo but the name that gets put into database did not change
do i have to add that line some where else
cheers
Doug

 

You have to change $pname along with photo's filename

ex if you use:
$target = "uploads/";
$target = $target .time().'_'.basename( $_FILES['photo']['name']);

Then $pname should be:
$pname = time().'_'.($_FILES['photo']['name']);;

 

thanks to all
now working
cheers
