I am new to PHP, I am doing the image upload function, the problem I have is that although successfully uploaded I don't have access to that image, is there any solution for this is not ?
my code:
public static function uploadImage($image){
try {
$rand = rand(1, 1000);
$target_save = "./Public/upload/".$rand.Helpers::slug($image['name']);
move_uploaded_file($image['tmp_name'], $target_save);
chmod($target_save, 777);
return Helpers::getUrlPage().trim($target_save, "./");
} catch (Exception $e){
return Helpers::getPathPublic('admin')."images/no_image.webp";
}
}
notification I get when opening pictures on my computer
It looks like you don t have permission to view this file check the permissions and try again
I tried running my application on xampp completely without this problem, but if I use MAMP PRO I will have this problem.
Have you checked the permissions of your file afterwards?
It seems like you are using an incorrect chmod mode
It is stated in the chmod documentation, that you should use octal values as secong argument.
An example:
chmod($target_save, 0777);
Also make sure the reading user has the correct permissions to read the file.

I make a site and it has this feature to upload a file and that file is uploaded to a server
Im just a newbie to php I download xampp and I run this site that i made in my local machine.
My site is like this you upload a file then that file will be uploaded to a server, but when i tried unlink() because when i try to remove the filename to a database I also want to remove that pic on the server, but instead I got an error and it says "Permission denied".
question:
How can I got permission to use unlink();?
I only run this on my localmachine using xampp
Permission denied error happens because you're trying to delete a file without having enough/right permissions for doing that.
To do this you must be using superuser account or be the same user that have uploaded the file.
You can go to the directory from your command line and check the permissions that are set to the file.
The easiest solution is to loggin as administrator/root and delete the file.
Here is another work around:
// define if we under Windows
$tmp = dirname(__FILE__);
if (strpos($tmp, '/', 0)!==false) {
define('WINDOWS_SERVER', false);
} else {
define('WINDOWS_SERVER', true);
}
$deleteError = 0;
if (!WINDOWS_SERVER) {
if (!unlink($fileName)) {
$deleteError = 1;
}
} else {
$lines = array();
exec("DEL /F/Q \"$fileName\"", $lines, $deleteError);
}
if ($deleteError) {
echo 'file delete error';
}
And some more: PHP Manual, unlink(), Post 106952
I would recommend, always first to check PHP Manual (in case your question concerns PHP), just go to the page with function that you have problems with and just click search CTRL+F in your browser and enter, for example, Windows, and as a result, in your case, you would find at least 7 related posts to that or very close to that what you were looking for.

How to use Unlink() function
I found this information in the comments of the function unlink()
Under Windows System and Apache, denied access to file is an usual error to unlink file. To delete file you must to change file's owern. An example:
<?php
chown($TempDirectory."/".$FileName,666); //Insert an Invalid UserId to set to Nobody Owern; 666 is my standard for "Nobody"
unlink($TempDirectory."/".$FileName);
?>
So try something like this:
$Path = './doc/stuffs/sample.docx';
chown($Path, 666);
if ( unlink($Path) )
echo "success";
else
echo "fail";
EDIT 1
Try to use this in the path:
$Path = '.'.DIRECTORY_SEPARATOR.'doc'.DIRECTORY_SEPARATOR.'stuffs'.DIRECTORY_SEPARATOR.'sample.docx';
I am having trouble using fopen() to create a text document for later use as a cookie file.
I have read the documentation for this function, but to no avail.
Notes:
Ubuntu
read / writable ("w+")
I have tried several storage locations including:
/home/jack/Desktop/cookie
/var/www/cookie
/home/jack/Documents/cookie
PHP
echo "debug";
echo "\r\n";
$cookie = fopen("/home/jack/Documents/cookie", "w+");
fclose($cookie);
if(!file_exists($cookie) || !is_writable($cookie))
{
if(!file_exists($cookie))
{
echo 'Cookie file does not exist.';
}
if(!is_writable($cookie))
{
echo 'Cookie file is not writable.';
}
exit;
}
Result
file is not created
Output to browser: debug Cookie file does not exist.Cookie file is not writable.
Other Fun Facts
I have tried using fopen(realpath("/home/jack/Documents/cookie"), "w+")
echo "\r\n" gives a space. Why not a newline?
I believe the problem must be something to do with my permissions to create the file, but I have no problem "right-click" creating the text document on the Desktop.
THIS WORKS THIS WORKS THIS WORKS THIS WORKS THIS WORKS THIS WORKS THIS WORKS
echo "debug";
echo "\n";
$jack = "jack";
$cookie = "/home/jack/Documents/cookie";
touch($cookie);
chmod($cookie, 0760);
if(!file_exists($cookie) || !is_writable($cookie))
{
if(!file_exists($cookie))
{
echo 'Cookie file does not exist.';
}
if(!is_writable($cookie))
{
echo 'Cookie file is not writable.';
}
exit;
}
fclose($cookie);
THIS WORKS THIS WORKS THIS WORKS THIS WORKS THIS WORKS THIS WORKS THIS WORKS
Instead of fopen()..
touch() to create
chmod() for permissions
I also added user name jack to www-data group.
chmod($path, 0760) group read / write
Reference
chmod() octal values here.
Look at the documentation for file_exists again. It does not take a file handle as an argument, it takes a string filename. The same is true for is_writable. Even if it did, you are opening the file handle and then immediately closing it, so I'm not sure why you're trying to use the file pointer at all after it's been closed.
You may be correct in that you have improper permissions set, but I would start here, first.
Also, if you're only trying to create the file, you may look into using the touch method, instead:
if( touch( $filename ) ) {
// It worked!
} else {
// It didn't work...
}
The web server is not executing as your user. touch /home/jack/Documents/cookie && chmod 777 /home/jack/Documents/cookie to allow the web server user to access the file.
Note this is BAD in production environments.
It looks like a permission issue. What user is PHP running as? It's likely running as www-data or something similar. You should make sure that the folders you are trying to write to are writable by either the user or group that PHP is running as. If you created those folders while logged in a jack, they probably belong to jack:jack and are not accessible by www-data:www-data.
You can also add jack to the www-data group, to make things a bit easier for development.
I am trying to create a folder in server. I wrote the following code
function CreateErrorLog($IntegrationId, $errorStr){
if (!is_dir(PUBLIC_PATH.'/errors/'.$IntegrationId)) {
echo 'not present<br/><br/>';
try{
mkdir(PUBLIC_PATH.'/errors/'.$IntegrationId, 0777);
}catch(Exception $e){
echo '<br/><br/> exception----'.$e.'<br/><br/>';
print_r($e);
}
}else{
echo 'present<br/><br/>';
}
}
I am getting output "not present" but I can`t see the directory created in the name of $IntegrationId under "errors" folder.
this is working in localhost. After moving to remote server I am getting the problem. What is the problem?
Issue can be errors folder might not be having write permission in server
If no permission, it will not through any exception.
Put the mkdir in if() condition. So you will understand from the return value.
And put ini_set('display_errors', 1); on top of your code.
Firstly check your path permission is writable.If this fine,you must mention absolute path instead of PUBLIC_PATH.you can get absolute path create a php file using function 'echo getcwd()'.This will show you absolute path.This choose on instead of PUBLIC_PATH.

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.
