i have created a file uploading system on a website that i have created and i need to know how the file can be over written.

the file thats are upload are only used once and the next time the user uploads a new file i want the last file to be over written. the code i am using to name the file on the server is this.


i no some a if statement will have to be placed in but when i tried to code it it stopped the upload working. i was using a unix time stamp at first but if i name the image it makes it easier for the image to be used in other sections of the site and for email purposes.

i am using something like this

<?	if (isset($_FILES['uploadingfile']['tmp_name'])) {
		if (!file_exists($uploaddir)) {
		//update query

<form name="frmresumeupload" enctype="multipart/form-data" method="POST">
File: <input type="file" name="uploadingfile" size="30"> <br />
<input type="submit" value="Upload!">

thanks for the reply i should get it working now.
