File Upload Error

My Php Buddies,

I am building a script where only video file uploading is allowed and the max size limit is 1MB.
Do have a look at the following code of mine and tell me which lines to fix substituting with what code from you.

I got 2 issues.
ISSUE 1: If I try uploading the same file then I should get error:

[code]
$Errors[] = “Error: You have already uploaded a video file to verify your ID!”;
[/code]

But, I do not get the error. Why is that ?
Code snippet is this:

[code]
//Grab Uploading File Extension details.
$file_extension = pathinfo($file_name, PATHINFO_EXTENSION);
if(file_exists(“$directory_path . $user/ . $file_name”)) //THIS LINE IS NOT GIVING THE ERROR THAT FILE HAS ALREADY BEEN UPLOADED. INSTEAD GIVES THE ECHO THAT IS 26 LINES BELOW HERE: “Your Video File “$file_name” has been uploaded successfully!”
//if(file_exists($directory_path . $user . ‘/’ . $file_name)) //THIS LINE IS NOT GIVING THE ERROR THAT FILE HAS ALREADY BEEN UPLOADED. INSTEAD SHOWING BLANK WHITE PAGE.
{
$Errors[] = “Error: You have already uploaded a video file to verify your ID!”;
exit();
}
[/code]

ISSUE 2: When I upload a file over 1MB max limit, I do not get the error as supposed to. Snippet looks like this:

[code]
//Verify File Extension.
if(!array_key_exists($file_extension, $allowed_file_extensions)) die(“Error: Select a valid video file format. Select an Mp4 file.”);
//Verify MIME Type of the File.
elseif(!in_array($file_type, $allowed_file_extensions))
{
$Errors[] = “Error: There was a problem uploading your file $file_name! Make sure your file is an MP4 video file. You may try again.”; //IS THIS LINE CORRECT ?
}
//Verify File Size. Allowed Max Limit: 1MB.
elseif($file_size>$max_file_size_allowed) die(“Error: Your Video File Size is larger than the allowed limit of: $max_file_size_allowed_in_megabytes.”);
//Move uploaded File to newly created directory on the server.
move_uploaded_file(“$file_tmp”, “$directory_path” . “$user/” . “$file_name”); //IS THIS LINE CORRECT ?
//Notify user their Id Verification Video File was uploaded successfully.
echo “Your Video File “$file_name” has been uploaded successfully!”;
exit();
[/code]

QUESTION 3:
I need to know if the following 2 lines are correct or not. If not, then how should they be ?
Check the comment lines:

[code]
//Feed Id Verification Video File Upload Directory path.
$directory_path = “uploads/videos/id_verifications/”;
//Make Directory under $user in ‘uploads/videos/id_verifications’ Folder.
if(!is_dir($directory_path . $user)) //IS THIS LINE CORRECT ?
{
$mode = “0777”;
mkdir($directory_path . $user, “$mode”, TRUE); //IS THIS LINE CORRECT ?
}
[/code]

The full script is:

[code]
<?php
//Required PHP Files.
include ‘header_account.php’; //Required on all webpages of the Site.
?>

<?php

if (!$conn)
{
$error = mysqli_connect_error();
$errno = mysqli_connect_errno();
print “$errno: $errorn”;
exit();
}

if($_SERVER[“REQUEST_METHOD”] == “POST”)
{
//Check whether the file was uploaded or not without any errors.
if(!isset($_FILES[“id_verification_video_file”]) && $_FILES[“id_verification_video_file”][“Error”] == 0)
{
$Errors = Array();
$Errors[] = “Error: ” . $_FILES[“id_verification_video_file”] [“ERROR”];
print_r($_FILES); ?><br><?php
print_r($_ERRORS);
exit();
}
else
{
//Feed Id Verification Video File Upload Directory path.
$directory_path = “uploads/videos/id_verifications/”;
//Make Directory under $user in ‘uploads/videos/id_verifications’ Folder.
if(!is_dir($directory_path . $user)) //IS THIS LINE CORRECT ?
{
$mode = “0777”;
mkdir($directory_path . $user, “$mode”, TRUE); //IS THIS LINE CORRECT ?
}

//Grab Uploading File details.
$Errors = Array(); //SHOULD I KEEP THIS LINE OR NOT ?
$file_name = $_FILES[“id_verification_video_file”][“name”];
$file_tmp = $_FILES[“id_verification_video_file”][“tmp_name”];
$file_type = $_FILES[“id_verification_video_file”][“type”];
$file_size = $_FILES[“id_verification_video_file”][“size”];
$file_error = $_FILES[‘id_verification_video_file’][‘error’];

//Grab Uploading File Extension details.
$file_extension = pathinfo($file_name, PATHINFO_EXTENSION);
if(file_exists(“$directory_path . $user/ . $file_name”)) //THIS LINE IS NOT GIVING THE ERROR THAT FILE HAS ALREADY BEEN UPLOADED. INSTEAD GIVES THE ECHO THAT IS 26 LINES BELOW HERE: “Your Video File “$file_name” has been uploaded successfully!”
//if(file_exists($directory_path . $user . ‘/’ . $file_name)) //THIS LINE IS NOT GIVING THE ERROR THAT FILE HAS ALREADY BEEN UPLOADED. INSTEAD SHOWING BLANK WHITE PAGE.
{
$Errors[] = “Error: You have already uploaded a video file to verify your ID!”;
exit();
}
else
{
//Feed allowed File Extensions List.
$allowed_file_extensions = array(“mp4” => “video/mp4”);

//Feed allowed File Size.
$max_file_size_allowed_in_bytes = 1024*1024*1; //Allowed limit: 100MB.
$max_file_size_allowed_in_kilobytes = 1024*1;
$max_file_size_allowed_in_megabytes = 1;

$max_file_size_allowed = “$max_file_size_allowed_in_bytes”;

//Verify File Extension.
if(!array_key_exists($file_extension, $allowed_file_extensions)) die(“Error: Select a valid video file format. Select an Mp4 file.”);
//Verify MIME Type of the File.
elseif(!in_array($file_type, $allowed_file_extensions))
{
$Errors[] = “Error: There was a problem uploading your file $file_name! Make sure your file is an MP4 video file. You may try again.”; //IS THIS LINE CORRECT ?
}
//Verify File Size. Allowed Max Limit: 1MB.
elseif($file_size>$max_file_size_allowed) die(“Error: Your Video File Size is larger than the allowed limit of: $max_file_size_allowed_in_megabytes.”);
//Move uploaded File to newly created directory on the server.
move_uploaded_file(“$file_tmp”, “$directory_path” . “$user/” . “$file_name”); //IS THIS LINE CORRECT ?
//Notify user their Id Verification Video File was uploaded successfully.
echo “Your Video File “$file_name” has been uploaded successfully!”;
exit();
}
}

I need you good peoples’ immediate attention on this.
Someone told me to try fileinfo() or finfo(). Can’t remember. She said that is more reliable. I don’t have access to her any more. And so, someone be kind enough to fix my code with fileinfo() or finfo() or whatever and show the code here so that I can learn from you ?
root ? nogdog ? ginerjm ? Anyone ?
