PHP - Failed to open stream: Permission denied while uploading image

Docker Desktop
, , ,

Trying to upload an image in PHP, I’m receiving an error: Warning: move_uploaded_file(…/upload/ferrari_logo.jpg): Failed to open stream: Permission denied in /var/www/html/mypage.php on line 108

Warning: move_uploaded_file(): Unable to move “/tmp/php8hHG6L” to “…/upload/ferrari_logo.jpg” in /var/www/html/mypage.php on line 108

I know I have to change the permission in the upload folder. I just wanted to know if how can I change these permissions in Docker?

mypage.php

<div class="photo_column">
<form method="post" id="upload_form" action="mypage.php" enctype="multipart/form-data">
    <div id="about_me_photo">

    <?php
        $message = '';
        $moved = false;

        if ($_SERVER['REQUEST_METHOD'] == 'POST') {
            if ($_FILES['photo_upload']['error'] === 0) {
                $temp = $_FILES['photo_upload']['tmp_name'];
                $path = '../upload/' . $_FILES['photo_upload']['name'];
                $moved = move_uploaded_file($temp, $path);
            } 

            if ($moved === true) {
                echo '<img id="about_me_img" src="' . $path . '"alt="">';
            } else {
                echo '<img id="about_me_img" src="" alt="">';
            }
        } else {
            echo '<img id="about_me_img" src="" alt="">';
        }

    ?>
            <div class="about_me_row">
                <input type="file" id="photo_upload" name="photo_upload" accept="image/*">
                <input type="submit" class="mypage_button"  id="submit_photo" value="Upload">
            </div>
            
        
    </div>
</form>
</div>

I hope this code will help you.

I entered the command line in to my docker-compose.yml file but I’m getting this line when I run docker:
php-apache-1 | chmod: changing permissions of ‘/var/www/upload’: Operation not permitted

Localhost:8000 doesn’t appear when I included the line and when I comment it out, it runs again.

Is there something I can do to fix it? Thank you

I added “sudo” after command and the errors clear up. I guess have to figure out how to display the images. Thank you
