I'm coding a website which allows the owner to make add/change/deletes to
his product database, which includes product images stored separately on the
server. I have coded the Delete page which deletes the product record from
the database, however the product image remains in the associated folder on
the server. I'd prefer these images not accumulate and would like to delete
these images along with the database record.

unlink() is a silly name for a delete command isnt it .

PHP: unlink - Manual

http://www.php.net/unlink

Deletes a file

Of course, you must read the filename from DB *before* deleting the record

Why? That's exactly what it does - removing the link to a file (and
probably decrementing the link count), isn't it? :)

It does a fair bit more than that, though. It also changes inode tables,
changes directory listings, etc.

Thanks for your example! I like your code's simplicity. The documentation at
php.net is difficult for me to follow.

However, I need to use variables in this code.

Specifically, I'm trying to do something like this:

$pass=0;
$filename="../{$_POST['hfCategory']}/photos/{$_POST['hfItemNumber']}.jpg";
if (!file_exists($ filename)) {$pass=1;}

if ($pass==1) {unlink($filena me);}

...but it's not working.

Any additional advice appreciated.

F.H.

I'd start by breaking it down a little .

$temp1="$_POST['hfCategory']";
print "temp1 = $temp1 ";

$temp2="$_POST['hfItemNumber']";
print "temp2 = $temp2 ";

$filename="$tem p1/photos/$temp2" . ".jpg";

Making sure you have the path 100% correct is the first step .

TMK "../" doesnt need to be used unless you have good reason to do so .

[OT] Your Sig

Just a sidebar here.

I normally don't pay attention to sigs. But I happened to glance at
yours and saw your encrypted email address. I think that's a great
idea. I'm going to have to see if there's something like that here in
the states.

Does it help stop spam?

You dont say what sig your talking about - but i'll take a wild guess
and assume its my own .

I think there one called 'cerbermail.com ' or summit that does the same
sort of thing if you dont mind google ads .

As for stopping spam - who knows .

Re: Advice on deleting images from server using PHP

I just want to agree with Frankie on "going one step at a time" when
building any path on any file system. Moreover, simple echos to those
variable often save you lots of frustration. I was working on something
similar and had a heck of a time until I realized that the path isn't being
built right.

Look at the headers.

Bloody hell krusty, Jerry Stuckle says you have a good idea. You'll not
be able to live this down in troll circles.

Yep, I figured since I was replying to you it would be obvious. Guess
not :-).

Thanks of the tip on cerbermail.com - but think I'll skip the google
ads. Maybe put it on one of my own sites.

Thanks again for your help.

I have found the error. Your original code's conditional statement read:

if (!file_exists($ filename)) {$pass=1;}

I missed the "!", so it would only delete the file if it did NOT exist. But
it does.

I have since corrected and simplified the code to this:

$pass=0;
$photo="../$hfCategory/photos/$hfItemNumber.j pg";
if (file_exists($p hoto)) {$pass=1;}

if ($pass==1) {unlink($photo) ;}

...and it works beautifully.

BTW: in my case, the "../" in the file path IS required in order to locate
the file. The actual sample file path is thus:
"../lifestyle/photos/6000.jpg"

F.H.

If you REALLY want to eliminate ALL spam with ZERO false positives go look
at www.validmail.net. Except during a server upgrade and mismatch, I
haven't received spam from there in over a year and a half.
