$_FILES problem

genista

Hi,
I have a script that allows a user to upload an image, and store that value in a database. If there is already a value in the database the script reverts to a section that allows the user to 'delete' the image and upload another one. In order to retrieve the image from a folder I am using a hidden field in some html to echo the file name then pull that into $_FILES ['imagefile']. The problem is that from the script below I get an undefined index on 'imagefile:'

echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN "http://www.w3.org/TR/html4/strict.dtd"> 
   <html lang="en"> 
    <form name="form1" method="post" action="" enctype="multipart/form-data"> 
    <input type="hidden" name="imagefile" value="<?php echo $image1; ?>"> 
    <p>&nbsp;</td><td><input name="submit" type="submit" value="Submit"></p> 
    </table> 
   </form>';
	//	exit;
	//move image1 to the delete folder.
echo "$image1";
	if(isset( $submit )) 
{  	

	if ($_FILES['imagefile'] == "$image1"){
	  echo "$image1";

If you need anything else, please let me know.

Thanks,

The $FILES array is populated by information about files which are uploaded from form elements of type "file". Your form doesn't have any. From the manual (handling file uploads):

<!-- Name of input element determines name in $_FILES array -->
Send this file: <input name="userfile" type="file" />

The file name would then be stored in $_FILES['userfile']['name'].

Ok, as there is no image actually being uploaded through a type "file" what can I use instead to move the file to another folder and replace image1 with the current image value to NULL?

Clearly what I have now is way off the mark....

Just $_POST[].....

Thanks, but sorry how will %_POST help here, can you elaborate a bit more please?

Submitted values (such as imagefile) will end up in $_POST.
