    Help with deleting images

    Could somebody help me with this script. It deletes a members images from their members menu, but it does not delete the images from the server.

    When it creates the images it creates a full size and thumbnail, but these are not getting deleted from the server when the user deletes them from their account.

    Could somebody wiser than me please help.

    Code:
    <?php
session_start();

if($session_access == false) {
	header("location: ./error.php?error=session");
}

include('i.setup.php');
include('i.connection.php');
include('i.function.php');

if($mode == "delete") {
	$query = mysql_query("SELECT image_id FROM image WHERE image_member_id = '$session_member_id' and image_status = 'A' ORDER BY image_id");
	while($data = mysql_fetch_object($query, $db)) {
		if(${"checkbox" . $data->image_id} == 1) {
			$sql = "UPDATE image SET image_status='D' WHERE image_id = '$data->image_id'";
			$result = mysql_query($sql);
		}
	}
}
?>

    Could anybody help. I think this is the sub routine that does the deleting.

    Code:
    if($mode == "delete") {
	$query = mysql_query("SELECT image_id FROM image WHERE image_member_id = '$session_member_id' and image_status = 'A' ORDER BY image_id");
	while($data = mysql_fetch_object($query, $db)) {
		if(${"checkbox" . $data->image_id} == 1) {
			$sql = "UPDATE image SET image_status='D' WHERE image_id = '$data->image_id'";
			$result = mysql_query($sql);
		}
	}
}

    That code will delete from a database, do you want the file deleted as well?? If so, then try this
    PHP Code:
    if($mode == "delete") {
            $query = mysql_query("SELECT image_id, image_file FROM image WHERE image_member_id = '$session_member_id' and image_status = 'A' ORDER BY image_id");
        while(    $data = mysql_fetch_object($query, $db)) {
            if(${    "checkbox" . $data->image_id} == 1) {
                    $sql = "UPDATE image SET image_status='D' WHERE image_id = '$data->image_id'";
                    $result = mysql_query($sql);
                    unlink($data->image_file);
            }
        }
    } 
    Since I don't know what the database looks like for this app, you need to replace everywhere I have typed image_file with whatever field in the database that has the filename of the image

    I tried your code, but I am having trouble replacing "image_file" in the two locations. Here is a copy of my database.

    http://www.avidnewmedia.com/~myphoto...s/database.gif

    It renames the file from "image_original" into 2 fields "image_name" and "image_ext". How do I call both of those?

    It also creates a second file to be used as a thumbnail called.... "thumb_NEW NAME OF FILE".

    So I need to delete the file it creats and its correspondign thumbnail that is created.

    That's the ticket. Try it and tell me how it goes

    Not really. That error means that unlink wasn't able to execute because it couldn't find the file.

    Verify the path to the file and also check that the file is there. You could also use file_exists to check if the file is there before deleting it and avoid the error message.
