So please can anyone help me with this two problems because i am really stuck there and don't know what to do and its the last problem i face and i can't solve it.
Thanks in advance;

What I have tried:

PHP

<?php
//set tiem zone
date_default_timezone_set('Asia/Dubai');
// Show errors
error_reporting(E_ALL);
ini_set('display_errors', 1);
	
// define Errors variables
$fnameErr = $lnameErr = $emailErr = $humanErr = $fileErr = $result = $result2 =  "" ;
	
// when we press submit do the following
if(isset($_POST['submit']))
{
// define contact form variables
$fname = $_POST['fname'];
$lname = $_POST['lname'];
$email = $_POST['email'];
$tel = $_POST['tel'];
$design = $_POST['design'];
$country = $_POST['country'];
$comment = $_POST['comment'];
$human = $_POST['human'];

// define Checks variables
$check1 = $check2 = $check3  = $check4  = "";

	
// Let's do some checks	
// Checking the First Name
if(empty($_POST["fname"])){
	$fnameErr = "Name is Required";
}else{
	$fname = test_input($_POST["fname"]);
	// check if name only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z ]*$/",$fname)) {
      $fnameErr = "Only letters and white space allowed"; 
    }else{
		$check1 = 1;
	}
}

    // check if e-mail address is well-formed
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
      $emailErr = "Invalid email format"; 
    }else{

	}
}

	}
}
	
// checking the attachment

        $fileErr = "Max allowed size is 2 MB";
        } else {

				$fileErr = "File $file_name has the extensions $ext which is not allowed";    
				}else{
					array_push($files,$file);}
	
			   }
	}

Solution 1

The error is quite clear: "Permission denied".

Guessing that line 115 is this:

PHP

$file = fopen($files[$x]['tmp_name'],"rb");

you should check the file name there (e.g. by checking the return value of fopen() and showing an error message with the file name upon FALSE).

But before trying to access an uploaded file you should check for upload errors (see PHP: Handling file uploads - Manual[^]):

PHP

$file_err = $file['error'];

if($file_err != UPLOAD_ERR_OK){
    $fileErr = "File upload failed";
}
else if($file_size > 2000000){
    $fileErr = "Max allowed size is 2 MB";
}
// ...

[EDIT]

Member 13120366 commented:
its mai() function not the fopen() function

Searching the web for "php mail permission denied":
php - mail: failed to open stream: Permission denied? - Stack Overflow[^].
It is probably the mail log file. If so, setup a log file for usage with PHP (mail.log in php.ini) that has the necessary permissions.

its mai() function not the fopen() function

Jochen Arndt 11-Apr-17 5:32am

See my updated answer.
For further questions it is always a good idea to indicate the code line for which the error is thrown.

Member 13120366 11-Apr-17 5:57am

i saw your answer and i have created already a file on the server with path /var/log/phpmail.log with 777 permissions but still nothing new same error received

Jochen Arndt 11-Apr-17 6:14am

And have you set the mail.log config too?

The log file should be stored in a directory where PHP already has write permission. /var/log is not such a directory and using 777 is not recommended.

Recommended:
- Create a directory (e.g. /var/log/php) as root
- Change the group of that directory to the group used by the web server (e.g. wwwrun, apache); owner will be still root
- Change the permission of the directory to allow the group to read and write (770)
- Specvify the file in php.ini: /var/log/php/mail.log
- Optionally create the file using touch, change owner and group to those used by the web server, and change permissions too (660)

Member 13120366 11-Apr-17 6:50am

i have created the folder in the root directory also i changed the permission of the directory to 770 then i specified the file in php.ini now i am stuck at points
1- Change the group of that directory to the group used by the web server
2- create the file using touch, as i created it as new file and thats all so if there is a refrence link to create this file please send it to me
excuse me because all of that is new to me and thank for your help and i appreciate it

Never create such directories at root level!

How to get the user and group of your web server depends on the used server and OS. With Linux you can try (as root; all following commands as root too):

lsof -ni | grep httpd

The 3rd column contains the user account name that runs the web server (often wwwrun).
If the lsof command does not exist on your system use

ps aux | grep apache

The above is for Apache. With other servers you may try "http" or "www" instead. The 1st column contains the user account.

To get the groups to which the user belongs (here for wwwrun):

groups wwwrun

Untested example. The follwing assumes:
Web server user = wwwrun
Web server group = www
PHP log sub directory name = php
PHP log file name = mail.log
php.ini: mail.log /var/log/php/mail.log

Move to the directory where you want to create the log sub directory (e.g. /var/log).

$ cd /var/log
$ mkdir php
$ chown root:www php
$ chmod 770 php
$ cd php
$ touch mail.log
$ chown wwwrun:www mail.log
$ chmod 660 mail.log
