file delete

chaza

I have an upload script that loads to folderA.
At the end of the script I have included a resize script that resizes the image to 500px and renames it then saves it to folderB.
Then it takes the file from folderB resizes to 100px renames it and saves it to folderC.
So the original uploads in folderA are redundant and wasting server space.
How can I delete them automatically once the resize script is finished with them?

Thank you.
But I am not sure how I reference the old file to unlink it.

stolzyboy

unlink("/full/path/to/folderA/file.ext");

chaza

ok, so if I don't know what 'file.ext' is I need to give it a variable, right?
So where, when & how do I do that?

stolzyboy

$variabletodelete = "file.ext"; //gotten from upload form, you obviously uploaded the file.ext so you can get it from there

unlink("/full/path/to/folderA/" . $variabletodelete);

chaza

how can I make that variable if I don't know 'file.ext' ?

stolzyboy

like i said, you obviously uploaded that file.ext so you could do some work on it to resize, etc... so you should have that variable, now just delete it form the respective folder...

The problem is the resize script I am using takes everything in a folder and resizes it.

So here is the resize script I am using, without defining what the functions are :
(added what I would like it to do in red)

$pics=directory("folderA","jpg,JPG,JPEG,jpeg,png,PNG");
$pics=ditchtn($pics,"n");
if ($pics[0]!=""){
foreach ($pics as $p){
createthumb("folderA/".$p,"folderB/n".$rdm.'.jpg',500,500);
}
}
$spics=directory("folderB","jpg,JPG,JPEG,jpeg,png,PNG");
$spics=ditchtn($spics,"tn");
if ($spics[0]!=""){
foreach ($spics as $p){
createthumb("folderB/".$p,"folderC/tn".$p,100,100);
}
}

$origpics=directory("folderA","jpg,JPG,JPEG,jpeg,png,PNG");
if ($origpics[0]!=""){
foreach ($origpics as $p){
unlink("folderA/",$p)
}
}

would that work?

stolzyboy

something like that should work, give it a whirl...

chaza

no, that don't work.

stolzyboy

that's why i said something like that would work, you need to try different combinations of stuff, and learn from the errors, use echo's to see if you are indeed getting the correct errors, etc...

chaza

OK I don't know why this isn't working!

after I upload a file I:

require ('generator.php'); // the resize script

Then I do:

echo("$uploadPath/$filename");

which gives me the correct file that I uploaded.

But when I do:

unlink($uploadPath/$filename);

it doesn't delete it! Arrgh!

chaza

unlink("$uploadPath/$filename");

worked. Hurrah!

So... ya see what happens when you try and try again. You succeed!!!
