图像上传/使用GD调整大小

Question

我正在尝试在上传时调整图片大小。我有上传代码，并添加了一些我发现的调整大小的代码。 Imagejpeg()返回false，因此可能存在问题。但我不知道它会是什么。

function processImg($id){
$file_result ="";
if($_FILES['image']['error'] > 0){
    $file_result .="No file uploaded or Invalid File";
    $file_result .= "Error Code: " . $_FILES['image']['error'] ."<br>";
    //header('Location: products.php');
    exit();
}
$path =  $_SERVER['DOCUMENT_ROOT'] . "/shop/imgs/" .$id."."."jpg";
$tmp = resize(308,173, $path);


/*if(!move_uploaded_file($tmp, $path)){
    ?> <script> console.log("ahoj") </script> <?php
}*/
return $tmp;
} 

function resize($width, $height, $path){
  /* Get original image x y*/
  list($w, $h) = getimagesize($_FILES['image']['tmp_name']);
  /* calculate new image size with ratio */
  $ratio = max($width/$w, $height/$h);
  $h = ceil($height / $ratio);
  $x = ($w - $width / $ratio) / 2;
  $w = ceil($width / $ratio);
  /* read binary data from image file */
  $imgString = file_get_contents($_FILES['image']['tmp_name']);
  /* create image from string */

  $image = imagecreatefromstring($imgString);


  $tmp = imagecreatetruecolor($width, $height);
  imagecopyresampled($tmp, $image,
    0, 0,
    $x, 0,
    $width, $height,
    $w, $h);
 $data = getimagesize($_FILES['image']['tmp_name']);
 var_dump($data);
$img = imagejpeg($tmp, $path, 100);

return img;
}
?>
