fopen woes

Anon

ok, I am trying to take a file off my hard drive and stroe inside a mysql database.

The following line allows me to do this-
$imagedata = addslashes(fread(fopen($userfile, "r"), filesize($userfile)));

($imagedata is the file I have selected from my hard drive)

Now on my 'add' function everything is ok but on my edit page where I anr to 'update' my filed the code seems to fail at the fopen stage.

With the following code (for troubleshooting purposes)-
($nu_userfile = is the result of my form)

echo $nu_userfile";
$imagedata2 = fopen($nu_userfile, "r");
if(!$imagedata2 ) die ("cannot open file");

I get this response

C:\delete.gif
cannot open file

whoich I do not understand- the variable is obvioult parsing from my form- C://delete.gif, but why does it fail at fopen?

As I say fopen works elsewhere, any ideas???

Exactly what are you trying to do?

In the grand scheme I want to store images in a field in my my sql database.

I have an 'add' page which has a form in it , one of the filed allows me select a file from my hard drive. I have named the field nu_userfile- thus giving this file location the variable name $nu_usefile.

I then 'process' $nu_userfile like this
$imagedata2 = addslashes(fread(fopen($nu_userfile, "r")));

I then 'insert' $imagedata2 into my database- and it is mi binary file.
So far so good this all works. I can add and view the graphic in the appropraite records (I also have 4 other fileds including id, date, title and description)

The problem arises on my 'edit' page where I want to update the fields. I have another form which 'inserts' the updated information into the database. This all seems to work for my text fileds, but my image updating seems to fail with this line

$imagedata2 = addslashes(fread(fopen($nu_userfile, "r")));

even though it worked perfectly in the add page.

Breaking it down in error checking, I have echo'ed the various elements

$nu_userfile echo as C:\file.gif (or whatever), but $imagadata2 comes out as blank. So it seems to fail at the fopen or fread stage. But I cant see why as the same line works elsewhere

any help is much appreciated as it is doing my head in

thanks in advance

1) are you sure the file does still exist?
2) Are you sure you are storing the filenames correctly, and not in a HTML format where the slashes are replaced by their html equivalents?

as mentioned in the firts mail, for error testing I have been doing this, and also echo the msql query-

echo $nu_userfile";
$imagedata2 = fopen($nu_userfile, "r");
if(!$imagedata2 ) die ("cannot open file");

I get this response

-C:\delete.gif
-cannot open file

Thus the file locatiopn is being kept in $nu_userfile, but doesnt get processed by the addshashes/fread/fopen command- yet it does in another file so I cant see why this doesnt
