Need PHP Help - Minecraft to Minetest Skin Converter

by TheReaperKing » Wed Jun 29, 2016 17:48

So I'm using RobbieF's code for part of it and I think I ALMOST having it working because it does successfully upload the image, I just need it to convert the uploaded image and put it in the covertedskins folder. Maybe some check too so that it doesn't erase a preexisting image already in coverted skins. Thanks for any help!

Code: Select all
<!DOCTYPE html>
<html>
<body>

<form action="minecrafttominetestskinconverter.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="fileToUpload" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>



<?php
// File Uploader

$target_dir = "skinuploads/";
$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
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($target_file)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($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 "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}

 } else { // already compatible. Just copy it.
 imagecopy($dest, $src, 0,0, 0,0, 64,32);
 }

 // Output to browser
 header('Content-Type: image/png');
 imagepng($dest);

 // Save to a file
 imagepng($dest,$output,0); // 0-9. 0=faster, 9=smaller.

 // Free up memory

 imagedestroy($src);

Here's how we do it, in case it helps you out... and now, I must review for any security holes - lol!

Don't use it verbatim (as it likely won't work for you as is -- you're missing some of our components), but glean ideas or help from it if you like.

Code: Select all
<?php
  require_once('./includes/header.php');

    $gallery['folder'] = '/home/robbie/minetest.tv/skins/uploads/';

    if(isset($_FILES['file']) && strlen(trim(strip_tags($_POST['username']))) > 0 ) {
      $username = trim(strip_tags($_POST['username']));
      $target_dir = '/tmp/';
      $target_file = $target_dir . basename($_FILES['file']['name']);
      $uploadOk = 1;
      $extension = pathinfo($target_file,PATHINFO_EXTENSION);
      if ($extension == 'png') {
        // Check if image file is a actual image or fake image
          $check = getimagesize($_FILES['file']['tmp_name']);
          if($check !== false) {

              $input = $_FILES['file']['tmp_name'];
              $skin['filename'] = 'player_' . $username . '.png';
              $skin['datestamp'] = date('U'); // fake it  :)
              $skin['username'] = $username;
              $output = $gallery['folder'] . $skin['filename'];
              if (!file_exists($output)) {
                // Create image instances
                $src = imagecreatefrompng($input);
                $dest = imagecreatetruecolor(64, 32);

                // Make it transparent
                imagesavealpha($dest, true);
                $trans_colour = imagecolorallocatealpha($dest, 0, 0, 0, 127);
                imagefill($dest, 0, 0, $trans_colour);

                // Learn the dimensions of the input image
                $size = getimagesize($input);

                if ($size[0] == 64 && $size[1] == 64) { // it has Minecraft 1.8 skin dimensions - convert!
                 
                  // Copy - Syntax is Dest X,Y, Source X,Y, Width,Height

                  // Head
                  imagecopy($dest, $src, 0,0, 0,0, 32,16);
                  // Head overlay
                  imagecopy($dest, $src, 0,0, 32,0, 32,16);

                  // The Leg and Arm become both left and right in 1.7-
                  // We'll simply discard the left arm and leg since it's not used.
                  // If you have an overlay on your left arm/leg but not right arm/leg, you might want to edit your skin since that will be discarded.
                  imagecopy($dest, $src, 0,16, 0,16, 64,16);

                  // Leg, Body and Arm overlay
                  imagecopy($dest, $src, 0,16, 0,32, 64,16);

                } else { // already compatible. Just copy it.
                  imagecopy($dest, $src, 0,0, 0,0, 64,32);
                }

Of course, "./skins/preview/front/' . $skin['username'] . '.png" doesn't actually exist. It's a render created by another script, which I'm also happy to share if you want. Perhaps I could add this stuff to GitHub.

This is awesome, thank you!! Since I know so little about PHP all of this helps me "learn the rules" of the language :)

Just remember it was never meant to be released verbatim... so you'll need to tweak it (it was built for our servers only). But surely it gives you some insight.

Good luck!
