Newbie - Unlink question

[unkempt]

Ok so i am using flash with php

 

the following works well if the unlink.php (below) resides in the "temporary" folder :

 

In flash:

[pre]path = "http://localhost/temporary/unlink.php?";

var file:String = "barth_t8.jpg";

 

del = new LoadVars();

del.delstr = file;

del.sendAndLoad(path, del, "POST");

 

del.onLoad = function(){

tracer = "file removed - "+this.removed;

}[/pre]

 

In PHP:

[pre]<?php

$myFile=$_POST[delstr];

unlink($myFile);

print "&removed=".$myFile;

?>[pre][/pre][/pre]

 

 

So.... if i was to make my path - "http://localhost/unlink.php?";  (i.e. no temporary folder)

how could i change this so flash tells the php which folder the file resides in and then delete it?

 

Any help would be appreciated

To provide the directory over the url, it'll need to be like this:

 

http://yoursiter.com/unlink.php?dir=path/to/file

 

Then in php you'd do:

if(isset($_GET['dir']) && isset($_POST['delstr']))
{
    $dir_path  = $_SERVER['DOCUMENT_ROOT'] . '/' . $_GET['dir'];
    $file_path = $dir_path . '/' . $_POST['delstr'];

    if(is_dir($dir_path) && file_exists($file_path))
    {
        unlink($file_path);
    }
    else
    {
        'ERROR: File (' . $file_path . ') does not exist!';
    }
}
else
{
    die('Invalid data!');
}

Excellent - that seems to work nicely - thankyou

Sorry to be a pain , but is there a way to let flash know its done the job??

 

Again i apologise for my ignorance - i am new to php

Looking at the Flash manual for the sendAndLoad function Flash can receive data from the page.

 

Change the following in the in unlink.php:

if(is_dir($dir_path) && file_exists($file_path))
    {
        unlink($file_path);
    }

 

to:

if(is_dir($dir_path) && file_exists($file_path))
    {
        unlink($file_path);

        echo '&deleted=OK&';
    }

 

Then in your flash change this:

del.onLoad = function(){
tracer = "file removed - "+this.removed;
}

to:

del.onLoad = function() {
   if(this.deleted== 'OK')
   {
      tracer = "file removed';
   }
}

Thankyou very very much - you have made my life a lot easier than the workarounds i had in mind.

 

Could you recommend any good starter books - i am fairly ok with actionscript but this php is doing my head in

I'm a complete novice at Flash and actionscript - rarely use it. PHP is a programming language, like all programming languages it takes time to grasp.
