OK, I need to code a PHP file that will do the following:

Let the user browse there machine for a picture (or link one);
Max file size / images size;
Make the file name the username with a number.. If I upload one: XinG01 and if I upload another XinG02 and so on...

I have the upload thing at the moment, but thats the only thing... Heres what I got:

PHP Code:


			
<html><head><title>XinG's Upload script</title></head></html>



<?



if(isset($submit)) {



$target_path = "uploads/";

$filesize = 100000;

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);



if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {

     echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";

     echo "<br>";

     echo "You can see your file at: <a href=\"./$target_path\">HERE</a>";

} else{

     echo "There was an error uploading the file, the file is possibly too large!!";

     echo "<br>";

     echo "The max file size is: $filesize kb";

}



} else {

?>



<form enctype="multipart/form-data" action="<? $_SERVER['PHP_SELF']; ?>" method="POST">

<input type="hidden" name="MAX_FILE_SIZE" value="<? echo "$filesize"; ?>" />

Choose a file to upload: <input name="uploadedfile" type="file" /><br />

<input type="submit"  name="submit" value="Upload File" />

</form>

<br>

View other peoples uploaded files <a href="./uploads/">here!</a>

<? 

}

?>

For this sort of stuff its much easier to use a database in terms of the naming aspect as there is no way of knowing how many images a user has uploaded without recording it in a database table, then you just count the number of entries in order to get the correct filename e.g Xing01.jpg

However in order to rename the file you simply use the rename function. You can assign $newimagename any value you want but in order to do this you must first know the file extension as otherwise if they upload a .gif and you assign $newimagename to image.jpg it wont work.

rename( $target_path . $_FILES['uploadedfile']['name'], $target_path . $newimagename );

To work out the fileextension you use the following code.

$filetype = strrchr($_FILES['uploaded file']['name'],'.');

So you could then combine 2 vars $newimagename = $username . $filetype;

Hope this helps
