Question

My current code (not working):

<label for="homepage"><h3>Home Page Image</h3></label><input type="hidden" name="MAX_FILE_SIZE" value="300000" /><input type="file" name="homepage" />
        <?php
            $tmp_name = $_FILES['homepage']['tmp_name'];
            $file_type= $_FILES['homepage']['type'];
            $name = strtolower($_POST['title']) . ".png";
            $upload_dir = "/slideshow/";
            $file_path = "$upload_dir/$name";
            list($width, $height, $type, $attr)=getimagesize("$tmp_name");

            if(isset($_POST['submit']) && $file_type == "image/png" && $width==800 && $height==250)
            {
                move_uploaded_file($tmp_name, "$upload_dir/$name");
            }
            elseif((isset($_POST['submit']) && ($file_type != "image/png" || $width!=800 || $height!=250)))
            {
                echo "<div class=\"errorcheck\">Please select an image that meets the requirements. </div>";
                echo "$width $height $type";
            }
        ?>
</br>

Returns “Warning: move_uploaded_file(slideshow/test.png) [function.move-uploaded-file]: failed to open stream: Permission denied in /home/xxx/xxx/back_end/add.php on line 93 Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move ‘/tmp/phpGXQv9g’ to ‘slideshow/test.png’ in /home/xxx/xxx/back_end/add.php on line 93”

I am a beginner to this so please explain in a simple way thanks.

You have pretty much no error handling, follow the recommendations on php.net:

http://www.php.net/manual/en/features.file-upload.post-method.php

To start with, for debugging at least print out the $_FILES array:

echo 'Here is some more debugging info:';
print_r($_FILES);
