Upload images using php

Question

I have a an input type file which is hidden and triggered using another button .. the input must upload images only to a folder named Covers but the code is not working and not uploading any image..
html code

<div class="cover">
    <img src="Layout/images/cover.jpg" alt="cover" name="cover-img" class="cover-img"> 
    <form action="<?php echo $_SERVER['PHP_SELF']?>" method="POST" enctype="multipart/form-data">
        <button type="submit" name="submit-cover" id="cover-btn">Change Cover</button>
    <input type="file" name="avatar" id="cover-img-input" class="hidden" />
</form>

php codes:

if($_SERVER['REQUEST_METHOD'] == 'POST') {
    if(isset($_POST['submit-cover'])) {
        $avatarName = $_FILES['avatar']['name'];
        $avatarTempName = $_FILES['avatar']['tmp_name'];

        // List of allowed image extensions
        $avatarAllowedExtensions = array("jpeg","jpg","png","gif");

        // Get avatar extension
        $avatarExtension = strtolower(end(explode('.',$avatarName)));

        // Check if uploaded image extension is in allowed image extensions
        $formErrors=array();
        if(! empty($avatarName) && ! in_array($avatarExtension, $avatarAllowedExtensions)) {
            $formErrors[]='This extension is <strong>not allowed</strong>';
        }
        if(empty($avatarName)) {
            $formErrors[]='No image <strong>uploaded</strong>';                                         
        }

        if(empty($formErrors)) {
            // Create random number between zero to million to concatinate it with image name
            $avatar = rand(0,1000000) . '_' . $avatarName;

            // Move image into Covers folder
            move_uploaded_file($avatarTempName, "Uploads\Covers\\" . $avatar);

        }
    }
}

I get

Fatal error: Undefined class constant 'MYSQL_ATTR_INIT_COMMAND' in D:\XAMPP\htdocs\Warina\connect.php on line 7

after that I searched for a solution and get this: extension=php_pdo_mysql.dll should be uncommented in my php.ini and it is uncommented now I'm confused about this error too.

Have you checked your error log if there are any clues about what's going on? A good idea is also to turn `display_errors` on in your local PHP environment.

Did you add the error display code suggested in @MagnusEriksson comment yet? — RiggsFolly, Aug 31 '18 at 19:54
@RiggsFolly yes I did what MagnusEriksson said and I got a fatel error says Fatal error: Undefined class constant 'MYSQL_ATTR_INIT_COMMAND' in D:\XAMPP\htdocs\Warina\connect.php on line 7 after that I searched for a solution and get this: extension=php_pdo_mysql.dll should bu uncommented in my php.ini and it's uncommented now I'm confused about this error too.. can you give me a solution — Raizada Dev, Sep 01 '18 at 09:13
So you had better show us `connect.php` and any code that attempts to access the database in this script — RiggsFolly, Sep 01 '18 at 10:59
Also run a little script with just this in the script. `phpinfo()` and look for the parameter `Loaded Configuration File` and check that is the `php.ini` file you have look at — RiggsFolly, Sep 01 '18 at 11:02

This line sends a notice:

$avatarExtension = strtolower(end(explode('.',$avatarName)));

Notice: Only variables should be passed by reference in file.php on line xx

Replace with

$avatarExtension = explode('.',$avatarName);
$avatarExtension = strtolower(end($avatarExtension));

Fix this path:

move_uploaded_file($avatarTempName, "Uploads\Covers\\" . $avatar);

With

move_uploaded_file($avatarTempName, "Uploads\\Covers\\" . $avatar);

And make sure it exists

The path exists I'm sure of that and also I replaced my lines with yours but still the problem exist and no image uploaded – Raizada Dev Aug 31 '18 at 19:38

Are you using a *nix where directory names are case sensitive, if so do the actual directory names contain a capital letter at the beginning – RiggsFolly Aug 31 '18 at 19:53

Its also simpler to use `/` rather than the escape character `\\` regardless of OS. PHP will work out what to actually use internally on any OS – RiggsFolly Aug 31 '18 at 19:55
