PHP - Unlink And Move_uploaded_file Issues

Howdy! I have been working in this custom script to manage some people on a group.. It will be really complete, with profiles, related stats and also an simple email client. But recently I have been having an issue with the function move_uploaded_file() to upload a picture to the user's profile.

Apparently it works for some files (which means the syntax and paths are correct), but for some others move_uploaded_file() returns FALSE and I just can't work it out.

Here is the part of the script that treats the uploading:
Code: [Select]
$target_path = "/opt/lampp/htdocs/emp/deeper/profiles/avt/"; //>>PATH<< to avt folder

if (!isAllowedAvatar($_FILES['picture']['name'])) { //Check for allowed filetypes
print "<div class='notif error bloc'><strong>Error :</strong> Wrong filetype. Image must be PNG file...</a></div>";
die;
}
if (file_exists($target_path.$basename.".png")) { //Rename old image to prevent loss of it in case of Failure
rename($target_path.$basename.".png",$target_path.$basename."_temp.png");
}

$old_path = $target_path;

$target_path = $target_path . $basename . ".png"; //Build new image path

if(move_uploaded_file($_FILES['picture']['tmp_name'], $target_path)) { //Moves uploaded image
print "File ".  basename($_FILES['picture']['name'])." correctly uploaded";
unlink($old_path.$basename."_temp.png"); //Deletes temp file
} else {
print "There was an error uploading the file, please try again!";
rename($old_path.$basename."_temp.png",$old_path.$basename.".png"); //Reverts the temp file to the original
}
I think the comments are enough for understanding it. Also, it looks like move_uploaded_file() is returning FALSE if the file is from Linux and had ownership stuff..
Any tip is welcome! Thanks for reading!

I upload an image and put every information inside $_SESSION['tmp'] and $_SESSION['path']
then once user click on button then i use

move_uploaded_file($_SESSION['tmp'],$_SESSION['path'])

but file uploaded not appeared in my upload folder, and again i try to echo everything but all information still kept well in $_SESSION

is there something missing here?

thanks

I used the move_uploaded_file function to upload files to my server ,but the function changes the Arabic names of files because most of my files are Arabic named  how can I fix that ?

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>

        </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

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?

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

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

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!

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

any help with this please? it works fine with deleting database results but the unlink wont unlink file from dir?

Code: [Select]
else if($action=="del")
{
    $id = $_GET["id"];
    $cls = $_GET["cls"];
    $dir = "gallery/$cls";
  echo "<p align=\"center\">";
 
  $owner = mysql_fetch_array(mysql_query("SELECT uid FROM gallery WHERE id='".$id."'"));
  if(mod(getuid_id($id))||getuid_id($id)==$owner[0])
  {
    $res = mysql_query("DELETE FROM gallery WHERE id='".$id."'");
$res2 = mysql_query("DELETE FROM comments WHERE pid='".$id."'");
$res3 = mysql_query("DELETE FROM rate WHERE pid='".$id."'");

    if($res||res2||res3 || unlink($dir))
        {
            echo "Photo Deleted From Gallery<br/>";
        }else{
          echo "Database Error!<br/>";
        }
  }else{
    echo "You can't delete this Photo";
  }

Basically i have a table show the contents of database (id, name, image type, image size). This is it,
http://dvplus.webuda.com/testing/delete-image.php
The image on the last column i want it have a href on that image that will delete the file directory that relevant on the table row. I tried to user <a href="<? unlink="" ?>img scr</a>.....,

any one got any idears???

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!

Hi all,

Please can somebody help me sort my script out?

I want it to delete the sql contents in the chosen table, and delete the file stored on server at the same time.
URL for server is stored in the database.
Everything works except for when it comes to deleting the file off the server. I just can't work it out/get my head around it.

Many Thanks in advance if you can help,

Steve

After a user on my site deletes their account I want their profile picture to be deleted from my images folder.   I was testing the unlink function on my index.php file and it is failing.

Here is the error: Warning: unlink(/assets/img/avatars/users/jasongordon.png): No such file or directory in /home/www-data/big.com/index.php on line 86

My code was just: unlink('/assets/img/avatars/users/jasongordon.png');

I'm not sure why this fails because my file does exist.
