PHP Upload image with given name

Question

I am using this function to upload the image:

<?php

    session_start();

if(!isset($_SESSION["user"]) or !is_array($_SESSION["user"]) or empty($_SESSION["user"])) {
      // redirect to login page
}



$target_dir = ('users/'.$_SESSION["user"]["id"].'/');
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image


// Check if file already exists

// Check file size

// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
        echo header('Location: main.php');
    }
}
?>

How would I change the file name to: profilepicture for example. As any user that uploads an image, it's uploaded to the users ID file but with the name of there actual image, rather than profilepicture.

You would change the information about $target_file capturing the file's actual name in the form during the upload. — Jay Blanchard

You can change the following line:

$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);

$_FILES["fileToUpload"]["name"] is the original filename, so change it to something like:

$target_file = $target_dir . 'profilepicture.'.pathinfo($_FILES["fileToUpload"]["name"], PATHINFO_EXTENSION);
