PHP - Wont Unlink File From Dir?

I have a download-list, and want to have a delete-button/link at each file. I have tried different codes, but i'm new to php and need some help.

if ($handle = opendir('files/engelsk/')) {
               while (false !== ($file = readdir($handle)))
                  {
                      if ($file != "." && $file != "..")
                  {
                        $en .= '&raquo; <a href="/files/engelsk/'.$file.'">'.$file.'</a>&nbsp;&nbsp;-&nbsp;<i><a href="#">Delete file</a></i><br />';
                      }
                   }
              closedir($handle);
              }

It's the "<a href="#">Delete file</a>" I want to be the delete-button.

Please help!

I've Basically got this script and everything works. Except for the part that it doesen't insert "$_FILES['file']['name']" into the image_url.

Any Ideas guys?



Code: [Select]
<?
include "includes/config.php";

if (isset($_POST['add'])) {
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png"))
&& ($_FILES["file"]["size"] < 20000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    if (file_exists("images/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
  echo $_FILES['file']['name'];
      }
    else
      {

      move_uploaded_file($_FILES["file"]["tmp_name"],
      "images/" . $_FILES["file"]["name"]);
      }
    }
  }
else
  {
  echo "Sorry, but only PNG, JPG, and GIF files are allowed.";
  }
  mysql_connect ($mysql_host, $mysql_user, $mysql_pass);
  mysql_select_db ($mysql_db);

$image_url = "http://localhost/admin/images/". $_FILES['file']['name'] ."";

$sql = "INSERT INTO test (title, link, description, image_url)
VALUES
('$_POST[title]', '$_POST[link]', '$_POST[description]', '$image_url')";

if (!mysql_query($sql))
  {
  die('Error: ' . mysql_error());
  }
header( 'Location: portfolio.php' );

mysql_close();
}

?>
Code: [Select]
<form enctype="multipart/form-data" method="post">
<p>
<strong>TITLE</strong><br/>
<input type="text" name="title" class="box"/>
</p> <p>
<strong>LINK</strong><br/>
<input type="text" name="link" class="box"/>
</p>
<p>
<strong>IMAGE</strong><br/>
<input type="file" class="box" name="file"/>
</p>
<p>
<strong>DESCRIPTION</strong><br/>
<input type="textarea" name="description" class="box"/>
</p>
<p>
<input name="add" type="submit" id="submit" tabindex="5" class="com_btn" value="ADD WORK"/>
</p>
</form>

So I really don't think I need to paste the code but

So what all this does is based on user input it creates a new html page based off of the template with a few different variables based on input. Then it makes a new row  and 3 cells in the home pages thread table that link to the page say who made it and what time they made it. Now it all works PERFECT (Im suprised how perfect on the first try actually) except for 1 tiny flaw which i think might be php not me but im not sure. The fwrite creates a new file but if the input contains any question marks (?) the link will work but no file will be created. For everyother character on teh standard keyboard its fine but not the question mark. What gives? thanks yall!

MOD EDIT: <code></code> tags changed to proper [code] . . . [/code] BBCode tags.

Well hello there, I want to create a script that writes a few PHP constants to a file called config.php. It does not work however, with the way I wrote it as below:

Code: [Select]
$configdata = "<?php
//Configuration File

\define("DBHOST", $dbhost);             //DB Hostname
\define("DBUSER", $dbuser);             //DB Username
\define("DBPASS", $dbpass);             //DB Password
\define("DBNAME", $dbname);             //Your database name
\define("DOMAIN", $domain);             //Your domain name (No http, www or . )
\define("SCRIPTPATH", $scriptpath);     //The folder you installed this script in
\define("PREFIX", $prefix);
?>";

$file = fopen('../inc/config.php', 'w');
fwrite($file, $configdata);
fclose($file);

I am getting this error 'syntax error, unexpected T_STRING in ...', and I have no idea how to fix it. Strangely the below codes using PHP variables work flawlessly:

Code: [Select]
$configdata = "<?php
//Configuration File

\$dbhost = '{$dbhost}';       //DB Hostname
\$dbuser = '{$dbuser}'; //DB User
\$dbpass = '{$dbpass}'; //DB Password
\$dbname = '{$dbname}';     //Your database name
\$domain = '{$domain}';     //Your domain name (No http, www or . )
\$scriptpath = '{$scriptpath}'; //The folder you installed this script in
\$prefix = '{$prefix}';    

?>";

//Write the config.php file...

$file = fopen('../inc/config.php', 'w');
fwrite($file, $configdata);
fclose($file);


This confuses me, all I did was to change the string to output from a list of variables to a list of constants, and it gives weird errors that I have absolutely no idea how to fix. Can anyone please lemme know what I did wrong? Thanks.

Hello. I wish to get a file name from a DB and then delete it from the server.

I have tried the code below. It gets the full url to the photo I wish to delete. It looks like this WITHOUT the spaces: http : // www . mysite . com/users/photo.jpg

Then it attempts to unlink it.

Code: [Select]
$result = mysql_query("SELECT PhotoURL FROM `$info` WHERE userid = '$UserID'") or die (mysql_error());

while ($row = mysql_fetch_array($result)) {
$myFile = $row['PhotoURL'];
unlink($myFile);
}



I get an error message like this (edited to remove my url, etc):

Code: [Select]
Warning: unlink() [function.unlink]: Unable to locate stream wrapper in /home/user/public_html/code.php : eval()'d code on line 64

What am I doing wrong? Also is there another way to delete server files?

the code below creates a table that lets me choose a row to delete from mysql database
<?php
$host="host"; // Host name 
$username="user"; // Mysql username 
$password="pass"; // Mysql password 
$db_name="testdocs"; // Database name 
$tbl_name="Docs"; // Table name 
       

        // Connect to server and select databse.
        mysql_connect("$host", "$username", "$password")or die("cannot connect");
        mysql_select_db("$db_name")or die("cannot select DB");
       
        // Build SQL query
        if(!isset($_POST['delete'])) $sql="SELECT * FROM $tbl_name ORDER BY id";
        else {
                $sql = "DELETE FROM $tbl_name WHERE";

                // add row id to where section
                for($i=0;$i<count($_POST['checkbox']);$i++){
                        if($i != 0) $sql.= "AND ";
                        $sql .= " id='" . $_POST['checkbox'][$i] . "'";
                }
     }

      $result = mysql_query($sql);
       if(isset($_POST['delete']))  header('Location: index.php'); // redirect
?>
<table  align="center" width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td><form name="delete" method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
<table width="400" border="1" cellpadding="3" cellspacing="1">
<tr>
<td colspan="5" align="center"><strong>Testimonials</strong> </td>
</tr>
<tr>
<td align="center"><strong>Select</strong></td>
<td align="center"><strong>ID</strong></td>
<td align="center"><strong>Name</strong></td>
<td align="center"><strong>Message</strong></td>
<td align="center"><strong>Download</strong></td>
</tr>
<?php while($rows=mysql_fetch_array($result)){ ?>
        <tr>
                <td align="center">
                        <input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>">
                </td>
                <td><? echo $rows['id']; ?></td>
                <td><? echo $rows['Name']; ?></td>
                <td><? echo $rows['Message']; ?></td>
                <td><? echo $rows['Download']; ?></td>
        </tr>
        <tr>
        <td colspan="5" align="center"><input name="delete" type="submit" id="delete" value="Delete"></td>
        </tr>
<?php  }
        mysql_close();
?>
</table>
</form>
</td>
</tr>
</table>

but what i am trying to do is add unlink() to the script so when i delete a row it deletes the linked file.
this bit is where the filename is shown like test.doc and the files are stored in the directory /test_docs
<td><? echo $rows['Download']; ?></td>

is there anyway to do it so it deletes the file

If I use code:
while ($row = mysql_fetch_assoc($result)) {
@unlink(SRV_ROOT . IMAGE_DIR . $row['image']);
}


What is the difference between
@unlink(SRV_ROOT . IMAGE_DIR . $row['image']);

AND

unlink(SRV_ROOT . IMAGE_DIR . $row['image']);

On this path is deleted image files, but why use symbol @
When it is used in syntax, and why?

Tanks in advance

hi again, i have a image uploading page, i wanna add a delete option to each image that was uploaded..

the code that im using is taking thumbnails from folder, displaying only 4 images per page, and when u click on thumbnail - original sized image comes up, heres the code:


<?php
$del = "delete";
//The directory to your images folder, with trailing slash
$dir = "uploads/thumbs/watermarkedthumbs/";
$dir2 = "uploads/";
//Set the extensions you want to load, seperate by a comma.
$extensions = "jpeg,jpg,png,gif";
//Set the number of images you want to display per page
$imagesPerPage = 4;
//Set the $page variable
if(!isset($_GET['page'])){
$page = 1;
}else{
$page = $_GET['page'];
}
//Load all images into an array
$images = glob($dir."*.{".$extensions."}", GLOB_BRACE);
$images2 = glob($dir2."*.{".$extensions."}", GLOB_BRACE);
//Count the number of images
$totalImages = count($images);
$totalImages2 = count($images2);
//Get the total pages
$totalPages = ceil($totalImages / $imagesPerPage);
$totalPages2 = ceil($totalImages2 / $imagesPerPage);
//Make sure the page you are on is not greater then the total pages available.
if($page > $totalPages){
//Set the currnet page to the total pages.
$page = $totalPages;
}
//Now find where to start the loading from
$from = ($page * $imagesPerPage) - $imagesPerPage;
//Now start looping
for($i = $from; $i < ($from + $imagesPerPage); $i++){
//We need to make sure that its within the range of totalImages.
if($i < $totalImages){
//Now we can display the image!

    echo "<a href='{$images2[$i]}'><img style='border:thin solid
  #FFF;margin-top:10px;margin-left:10px;margin-right:10px ' src='{$images[$i]}'alt='{$images[$i]}' /></a>";
    
}
}

//Now to display the page numbers!
for($p = 1; $p <= $totalPages; $p++){
if($p == $page){
$tmp_pages[] = "<strong>{$p}</strong>";
}else{
$tmp_pages[] = "<a href='?page={$p}'>{$p}</a>";
}
}
//Now display pages, seperated by a hyphon.
echo "<br/>" . implode(" - ", $tmp_pages);

?>


i was thinking of adding another echo he

if($i < $totalImages){
//Now we can display the image!

    echo "<a href='{$images2[$i]}'><img style='border:thin solid
  #FFF;margin-top:10px;margin-left:10px;margin-right:10px ' src='{$images[$i]}'alt='{$images[$i]}' /></a>";
    
}

and then doing something with unlink..

do i need to look for something else to add a delete button to each image uploaded?
thanks

Hi,

I have a function that resides in a class, this function deletes a file in a specific folder.
This works, the file is deleted but I get the warning that he can't find the file in the folder.

So here's the error:

Quote

Warning: unlink(/Applications/MAMP/htdocs/wordpress/wp-content/plugins/flashplayer/player/songs/14-i_cant_go_on_ill_go_on_feat._vanessa_hudgens-everything_i_own.mp3) [function.unlink]: No such file or directory in /Applications/MAMP/htdocs/wordpress/wp-content/plugins/flashplayer/xml.php on line 122


And here's the code:

Delete function:
function remove_mp3_file(){

$target_path = dirname(__FILE__)."/player/songs/";
unlink($target_path.$this->filename);

}

function that calls the remove function:

function remove_xml_item(){

//$this->open_xml_playlist();

$xml = new DOMDocument('1.0', 'UTF-8');
$xml->preserveWhiteSpace = false;
$file = dirname(__FILE__)."/player/music.xml";
$xml->load($file);

$xpath = new DOMXPath($xml);
$query = '//song[title="'.htmlentities($this->title).'" and artist = "'.htmlentities($this->artist).'" ]';
$entries = $xpath->query( $query );

foreach( $entries as $entry ){

$entry->parentNode->removeChild($entry);

}

$savefile = $xml->save($file);

$remove_file = $this->remove_mp3_file();

if( (!$savefile) && (!$remove_file) ){
return false;
}elseif( ($savefile) && ($remove_file) ){
return true;
}

}

First I thought that it was I set a variable that calls the delete function and then I use a if statement for this, but it wasn't that.

Anyone an idea?

Thanks!

Not used unlink function before so a bit unsure. I do need it to remove a file in a different directory than the one the unlink function is in - it's actually in a parent sub directory.

Is there another way of doing this if unlink is unsuitable or can someone help me correct my code?

Code: [Select]
        elseif ( $action == "dlt" && $step == "2" ) {

          mysql_query('DELETE FROM items WHERE auto_increment = "'.$auto_increment.'"') or die( mysql_error() );

            $small = "../admin/imgs/small/90_'.$auto_increment.'.jpg";
              unlink( $small );
            $large = "../admin/imgs/small/250_'.$auto_increment.'.jpg";
              unlink( $large ); }

Cheers

I have a config file that lists a file like so..

Code: [Select]
$file1 = 'storagefolder/mydatabase.txt';
How can I delete the file "mydatabase.txt" that is in another directory 'storagefolder' ?

Code: [Select]
unlink($file1);gives an error that says not such file or directory

Hello everyone.
I am having trouble trying to write some script that will unlink all files in a directory. Can anyone help me? I am not sure of the best way to do this? Thankyou. 

I wonder whether someone may be able to help please.

I've put together the following page http://www.mapmyfinds.co.uk/development/deletetest.php which allows users to view a gallery of their uploaded images.

I'm now starting to work on the `deletion` functionality and I've attached a suitable icon and the Javascript code so the user can select the image to delete. From the research I've done, I know that to delete the files from my server I need to use the PHP `unlink` command. The problem I'm having is I'm not sure how to tie up the 'deletion' selection made by the user and the physical deletion of the files.

I've added my `unlink` code below which uses the relative path and then for the thumbnails, Ive added the echo source filename, so the image in the Thumbnails folder matches the one of the same name in the gallery being deleted, but as I said, it's at this point that I'm not sure what to do next.

Code: [Select]
<?php 

unlink($path);
unlink($path . 'Thumbnails/' . "<?php echo $source; ?>");
?>
I just wondered whether someone could perhaps have a look at this please and possibly provide some guidance on how I can link up the Javascript `click` event and the deletion of the files.

Many thanks and kind regards

Hi guys,

Hi.  I'm trying to make my folder management tool able to remove stuff.  Problem is, I get permission denied.   I've checked the NFTS perms for the share and for the folder.  It's also not read only.  I logged into my other workstation as the service account the web server is using and opened a DOS window and did "rd \\server\share\folder" and it removed it no problem.  It just fails in PHP.  Any idea what I should be looking at?   Thanks!
