PHP - Deleting variable and file together

Hi,
I have file uploading system which saves file and some info about it:

PHP Code:

---

$target_path = "uploads/"; // directory CHMODed to 777.

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 

move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path); 
$filename = basename($_FILES['uploadedfile']['name']); 


---

so I have file saved in uploads/ and also I have $filename
how I can delete file and all the row in mysql by pushing one button???

If you need more info -ask :) thanks ;)

To delete a file, use unlink, to delete a variable use unset.

Maybe?:

PHP Code:

---

unlink($target_path); 


---

1. File: as above, use unlink() in PHP-- use the filename AND path, so unlink('uploads/example.file');

2. To delete from a mysql database, use the DELETE command:
DELETE FROM `tablename` WHERE `something` = `somevalue`;

(For example, `id`=`8`, or `filename`=`example.file`)

I got unlinking problem

PHP Code:

---

Warning: unlink() [function.unlink]: http does not allow unlinking in /home/freecorplietuv/domains/laisvasprotas.xz.lt/public_html/admin/patvirtinti.php on line 19 


---

in row 19 is written: $del = unlink($file_path);

Whats wrong?

You can't unlink 'http://'

then what I have to unlink??
Can you post some egzamples?

PHP Code:

---

unlink("file.php"); 


---

$filepath has a prefix of http://

PHP Code:

---

<form method="post">
<input name="set" type="hidden" value="1" />
<input type="submit" value="Delete" />
</form>
if (isset($_POST['set'])) {
unlink($target_path . $filename);
SQL commands here to remove
}

1. bluewalrus, that code is fine but very dangerous: having direct user input to deleting files is very messy. Some sort of error checking would be very wise. Make sure they aren't deleting a higher level folder, and make sure the folder exists before unlinking it, at the very least. Unless this is a very limited application, it's best to only allow that sort of thing for logged in admins, etc. Otherwise, having some sort of non-transparent system is best, like a form that corresponds to a database where the real path is stored-- then it is hidden from the users so they can't write in any folder to delete-- only the ones stored in the database.

2. "http:"-- You do not use the URL (like "http://example.com/file.php"). Instead, use the RELATIVE path: (file.php) or (directory/file.php), etc.

djr33, you cannot delete higher level files. But yes - NOT secure.

You can't delete the containing folder but why not a parallel file like:
dir/subdir2/example.php from dir/subdir1/del.php-- path: ../subdir2/example.php
similar to dir/ex2.php using ../ex2.php

I have never had the need to try it though. You could easily do it with an include, regardless.

I don't understand... But say this is your root folder layout:
http://localhostr.com/files/18826c/capture.png

Within includes/unlinkthis.php, you could not do:

PHP Code:

---

unlink("../examples/file.php"); 


---

can someone show me how to create form where you can choose in RADIO style.
Also it has two buttons and one value to send - ID.
One button deletes existing file, other renames it to good.png

but everythin in one form. Also some php before header I think :D thanks

PHP Code:

---

<?php
function get_files(){
  $files = glob("*");
  $radio = array();
  foreach($files as $key => $value){
    if(is_dir($files[$key])){
      unset($files[$key]);
      continue; //thanks to techietim
    }
    $radio[] = '<input type="radio" name="delete" id="'.$key.'" value="'.$value.'" /><label for="'.$key.'">'.$value.'</label><br />';
  }
  return implode($radio);
}
if(isset($_POST['submit'])){
  unlink($_POST['delete']);
}
if(isset($_POST['rename'])){
  rename($_POST['delete'], "good.png");
}
?>
<form action="" method="post">
<?php
echo get_files();
?>
<input type="submit" name="submit" value="Submit"/>
<input type="submit" name="rename" value="Rename"/>
</form>

ok, looks great... Can you explain how it works? I dont understand the function thing... (also, why you use global?)

It's glob(). It gets all the files in the directory.

The first function of the code gets all the files, and displays them in radios.

And the next part renames/unlinks.

How'd it work out for you?

I am really sorry Nile, that I haven't seen your last posts... I was working on something else...

So, it works great :D

But one more question. I have mysql information of file:

$name
$directory
$username - who uploaded.

How I can let to see only those files to owners, which only they uploaded.
I don't want that everyone could delete all files...
