file-system path creation error (file upload) - php

my code keeps on saying that the folder does not exist though it should be checked by the mkdir function..it creates the folder but does not go through the uploading process.. and displays the error on the couldnt find the folder.. is the algorithm correct? please help.. Your advice will help! :)
here is the code..
if(!(file_exists($target_path)))
{
if(!mkdir($target_path, 0777, TRUE))
{
die ("could not create the folder on mkdir");
}
//in this line the error occurs..printing what is below..//
die ("could not find folder on file exists");
}
else
{
umask($target_path);
...
}

file_exists() routine requires the complete path to file like
/var/www/uploads/file1.c
so the
file_exists($target_path);
call is ok . but second call to make directory, ie,
mkdir()
is requiring an directory , not an path to an file ie, it require /var/www/upload part only .
so you can remove the basename from path name and apply it to mkdir function()

try..
if(file_exists($target_path) && is_dir($target_path)){ //rest of the code...
}
instead of...
if(!(file_exists($target_path))){
}
Hope this will do something for you...
...............................
one thing more...
i think the problem is with if(!(file_exists($target_path))){} Statement,
THIS SHOULD BE...
if(!file_exists($target_path)){}

during the file upload process, your file saving path in move_uploaded_file()
function may be creating problem. I am saying may be because your given code is not clear enough to me. Second parameter of move_uploaded_file() is the destination where first parameter is the file name. please check the value of $target_path, it may solve your problem. thank you.

Php Problem with move_uploaded_file. It seems everything is fine but it is not working

I am trying to use move_uploaded_file but I think everything is fine but my code is not working. Everything is working as expected even image name is being inserted into DB but it is not moving into uploads folder. Folder is there and apache2 does have access to write it.
I don't have enough reputation to post more then 8 lines so everything is on pastebin Here. The main aprt is...
$post_image_new_name = uniqid('', true). "."
.$post_image_actual_ext;
$post_image_destination = '../../uploads/';
if (is_dir($post_image_destination) && is_writable($post_image_destination)) {
$post_image_destination = '../../uploads/'.$post_image_new_name;
var_dump($post_image_destination);
move_uploaded_file($post_image_new_name, $post_image_destination);
echo "Inside move_uploaded_file section";
https://pastebin.com/Z321R76z
Try this code
line 53: move_uploaded_file($_FILES['addPost_post_image']['tmp_name'], $post_image_destination);
The first param should be the file source name.
move_uploaded_file() expects the source filename of the uploaded file. So you must use something like this:
move_uploaded_file($_FILES['addPost_post_image']['tmp_name'], $post_image_destination);

Cannot unlink file in Codeigniter

In my project I have a folder secure in root. The project package looks like:
application
secure
system
...........
Inside secure folder I am uploading some images on form submit using
$config1['upload_path'] = './secure/';
$ext = end(explode(".", $_FILES['thumb_image']['name']));
$config1['file_name'] = time().$_FILES['thumb_image']['name'];
$config1['allowed_types'] = 'jpg|png|jpeg|gif|bmp|jpe|tiff|tif';
$this->load->library('upload', $config1);
$this->upload->initialize($config1);
$this->upload->do_upload('thumb_image');
and it is working properly. Now while on editing the details, using another form, if I am uploading a new image instead of the current image file, I want to unlink the current one and then upload new file.
For this I am using the code:
unlink(base_url("secure/".$data['row']->videothumbnail));
I also tried with
unlink('/secure/'.$data['row']->videothumbnail);
where $data['row']->videothumbnail) is the current image file from database. New file is successfully uploaded. But old file is not getting unlinked. I have set the permission of secure folder to 777. But the images are uploaded with read only permission. Is it because of this, it is not getting unlinked?
Can anyone help me to solve this?
Thanks in advance.
Try this:
Set the permission dynamically using:
#chmod('./secure/'.$data['row']->videothumbnail, 0777);
then try unlink:
#unlink('./secure/'.$data['row']->videothumbnail);
Try echoing the path that you are providing to unlink function.
It should be something like this:
base_url()."secure/".$data['row']->videothumbnail;
I also had this issue even after setting the right permission on the folder. But the following code worked for me.
unlink(realpath(APPPATH . '../uploads').'/'.$ImageName);
Try to use $_SERVER['DOCUMENT_ROOT'] instead of base_url
$this->load->helper("file")
unlink(base_url('folder/file.ext'));
location:
\app\controller
\system\libraries
**folder\file.ext**
$unlinkUrl = "secure/".$data['row']->videothumbnail;
if(file_exists($unlinkUrl)){
unlink($unlinkUrl);
}
else{
echo $unlinkUrl." is not available";
}
I think you are just making a stupid mistake.
Firstly, the first param of unlink should be a relative path or absolute path, but base_url function will return you a path contains domain name, HOW CAN YOU DELETE A FILE ON REMOTE SERVER ?
Secondly, '/secure/'.$data['row']->videothumbnail here is not a relative path but a absolute path
YOU MUST change it into /the/absolute/path/to/secure/ or ./the/relative/path/to/secure/ (DO NOT MISS THE DOT)
use this to unlink
$oldthumb = "secure/".$data['row']->videothumbnail;
#unlink($oldthumb);
First Load the $this->load->helper("file") and then unlink it
unlink("secure/".$data['row']->videothumbnail);
if ($rowAffected > 0) {
if ($isMediaUpload)
if (file_exists('./uploads/' . $this->input->post('img_url')))
unlink('./uploads/' . $this->input->post('img_url'));
redirect('/admin/configration', 'location');
}
Though i came in late but someone might need this .
unlink(FCPATH."secure/".$data['row']->videothumbnail)
**FCPATH** - path to front controller, usually index.php
**APPPATH** - path to application folder
**BASEPATH** - path to system folder.

PHP mkdir() failing to work

Here's my code; I've renamed the directories, obviously. ;)
$thepath = "/var/www/vhosts/sub.domain.co.uk/web/apps/storage/".$userclient."/evidence/".$scid."/".$doctype."/";
$testdir = is_dir($thepath);
if ($testdir == false) {
mkdir($thepath, 0777);
}
In this case, the following variables apply;
$userclient = '000';
$scid = '9263';
$doctype = 'Insurance Policy';
So, the path should be;
/var/www/vhosts/sub.domain.co.uk/web/apps/storage/000/evidence/9263/Insurance Policy/
I know this works, EVERYWHERE else in my code, I have other applications using an almost identical setup. But the one above, appears to be tripping up on /evidence/ - it sets the permissions to 755, but will then create the directories per time I run the code, if I set evidence to 777 (Octal).
I get the following error message using;
if (!#mkdir($thepath)) {
$error = error_get_last();
echo $error['message'];
}
mkdir(): No such file or directory
Any help would be greatly appreciated, I have to finish this application by Thursday - and this file upload part is the last bit!
Thank you!
PHP can't find directory in which you want to create other directory.
You need to set $recursive param as true:
mkdir($thepath, 0777, true);
Maybe you want to try mkdir($path,$mode,true) to create missing links as well?

PHP move_uploaded_file not working into public server

I am trying to upload my php project into public server.
I made the image upload file when I create product or edit product.
It works in localhost, but when I move to public server, it is not working.
I think move_uploaded_file part does not working.
How can I change the link? or do I have to change anything?
When I see Filzilla, I can see remote site that it is '/www/eshopProject/inventory_images'.
And index file is '/www/eshopProject/storeAdmin'.
Do I have to change link like this?
I don't know how can I change the link.
Could you help me? uploading the image into public server is not working..
Is it any security issue? or something?
Please help me. Thanks.
--index.php--
$pid = mysql_insert_id();
//Place image in the folder
$newname = "$pid.jpg";
move_uploaded_file($_FILES['fileField']['tmp_name'], "../inventory_images/product_$newname");
First of all check the permissions of the directory as mentioned in come of the comments.
If you have shell access "chmod 777 target_dir" or "chmod 707 target_dir" should be sufficient.
Second try to debug it using if's and the file_exists function(http://php.net/manual/en/function.file-exists.php).
Something like this.
$uploadedFile = $_FILES['fileField']['tmp_name'];
$destination = "../inventory_images/product_$newname";
if(file_exists($uploadedFile))
{
echo "file uploaded to temp dir";
}
else
{
echo "file upload failed";
exit();
}
if(move_uploaded_file($uploadedFile, $destination))
{
echo "upload complete";
}
else
{
echo "move_uploaded_file failed";
exit();
}
You can also check your current working directory by using the FILE or DIR constants(http://php.net/manual/en/language.constants.predefined.php).
Try this.
echo __FILE__;
echo dirname(__FILE__);
echo __DIR__;
Use the copy() method. For me it worked.
copy($tmp_file, Destination) or
copy($tmp_image, IMAGE_DIRECTORY . SAM . $product_image);
Make sure you have write file permissions set to the folder you are trying to upload too.
I recommend setting the folders to "755" permissions and retry. This would make the permissions a little tighter.
This question is a bit old but i recently faced a similar issue where even with permission 777 on the upload folder it wouldn't work.
The issue was that the SELinux (https://wiki.centos.org/HowTos/SELinux) was on enforcing mode so i had to change it to permissive mode and then the upload works perfectly.
I hope this can help someone facing this issue.

PHP - Failed to open stream: no such file or directory - for existing file

I'm writing a PHP application and in my code i want to create create and return images to the browser. However, sometimes i'm getting some weird results where the image cannot be created since the file does not seem to exist.
Here is a sample error message I get and the code in a nutshell. I do know that the image exists, but still the method sometimes fails, and sometimes it succeeds, even for the same file.
The error:
Warning: imagecreatefrompng(path/to/image.png) [function.imagecreatefrompng]: failed to open stream: No such file or directory in file test.php on line 301
The code:
if (file_exists($filename)) {
$image = imagecreatefrompng($filename);
}
I would greatly appreciate any hints or tips of what might be wrong and how I can improve the code to be more stabile.
I suggest you use is_readable
if (is_readable($filename)) {
$image = imagecreatefrompng($filename);
}
The file may "exist" but is the file accessible? what does file_exists actually do?
if it opens the file and then closes it make sure that the file is actualy closed and not locked before imagecreatedfrompng fires.
it would be a good idea to try catching the error in a loop and make 4 or 5 attempts before handing back a controlled error.
maybe try is_readable() or is_writable() instead?
Have you considered checking for the correct permissions? If the file cannot be read, but the directory can, you would get file_exists(...) = true, but would not be able to open a handle to the file.
Use is_readable() to check whatever you have permission to access that file.
You can try GD :
IF($img = #GETIMAGESIZE("testimage.gif")){
ECHO "image exists";
}ELSE{
ECHO "image does not exist";
}
bro check for white spaces in your filepath. I recently had this issue while i was tring to include a file from a module i was creating for an app. Other modules included well when called but one didnt. It turned out that there was a white space in the filepath. I suggest u try php trim() function. If this works holla.
