Я пытаюсь загрузить несколько изображений за раз, при этом для каждого изображения также создается и сохраняется большой палец. Функция скрипта не работает?

Question

Это обновленная / отредактированная запись скрипта, которая отлично подходит для загрузки нескольких изображений. Проблема заключается в попытке создать большой палец для каждого загруженного изображения. GALLERY_IMG_PATH , GALLERY_IMG_FULLSIZE и GALLERY_IMG_THUMB определены в файле конфигурации и представляют собой просто информацию о пути. Сценарий, который я использую:

$errors = array();
$uploadedFiles = array();
$extension = array("jpeg","jpg","png");
$bytes = 1024;
$KB = 1024;
$totalBytes = $bytes * $KB;
$counter = 0;
if(isset($_FILES["images"]["tmp_name"])) {
foreach($_FILES["images"]["tmp_name"] as $key=>$tmp_name) {
$temp_Name = $_FILES["images"]["tmp_name"][$key];
$images_Name = $_FILES["images"]["name"][$key];
if(empty($temp_Name)) {
break;
}
$counter++;
$UploadOk = true;
if($_FILES["images"]["size"][$key] > $totalBytes) {
$UploadOk = false;
array_push($errors, $images_Name." file size is larger than the 1 MB. You must 
upload images smaller than 1MB.");
}
$ext = strtolower(pathinfo($images_Name, PATHINFO_EXTENSION));
if(in_array($ext, $extension) == false){
$UploadOk = false;
array_push($errors, $images_Name." is an invalid file type. Images must be 
either of the following: jpeg | jpg | png");
}
if(file_exists(GALLERY_IMG_PATH."/".GALLERY_IMG_FULLSIZE."/".$images_Name) == 
true) {
$UploadOk = false;
array_push($errors, "Attempted to upload an image that is already uploaded/the 
image name conflicts with an image that already uses the 
name:".$images_Name.".");
}     
if($UploadOk == true) {
move_uploaded_file($temp_Name, 
GALLERY_IMG_PATH."/".GALLERY_IMG_FULLSIZE."/".$images_Name);
array_push($uploadedFiles, $images_Name);
// Get the image size and type & Load the image into memory
$attrs = getimagesize (GALLERY_IMG_PATH."/".$images_Name);
$imageWidth = $attrs[0];
$imageHeight = $attrs[1];
$imageType = $attrs[2];
switch ($imageType) {
case IMAGETYPE_JPEG:
$imageResource = imagecreatefromjpeg 
(GALLERY_IMG_PATH."/".GALLERY_IMG_FULLSIZE."/".$images_Name);
break;
case IMAGETYPE_PNG:
$imageResource = imagecreatefrompng 
(GALLERY_IMG_PATH."/".GALLERY_IMG_FULLSIZE."/".$images_Name);
break;
default:
trigger_error ("Post::storeUploadedImage(): Unhandled or unknown image type 
($imageType)", E_USER_ERROR);
}
// Copy and resize the image to create the thumbnail
$thumbHeight = intval ($imageHeight / $imageWidth * GALLERY_THUMB_WIDTH);
$thumbResource = imagecreatetruecolor (GALLERY_THUMB_WIDTH, $thumbHeight);
imagecopyresampled($thumbResource, $imageResource, 0, 0, 0, 0, 
GALLERY_THUMB_WIDTH, $thumbHeight, $imageWidth, $imageHeight);
// Save the thumbnail
switch ($imageType) {
case IMAGETYPE_JPEG:
imagejpeg ($thumbResource, GALLERY_IMG_PATH."/".GALLERY_IMG_THUMB, 100);
break;
case IMAGETYPE_PNG:
imagepng ($thumbResource, GALLERY_IMG_PATH."/".GALLERY_IMG_THUMB, 100);
break;
default:
trigger_error ("Post::storeUploadedImage(): Unhandled or unknown image type 
($imageType)", E_USER_ERROR);
}
}
}
}
if($counter>0){
if(count($errors)>0)
{
echo "<b>Errors:</b>";
echo "<br/><ul>";
foreach($errors as $error) {
echo "<li>".$error."</li>";
}
echo "</ul><br/>";
}
if(count($uploadedFiles)>0) {
echo "<b>Uploaded Files:</b>";
echo "<br/><ul>";
foreach($uploadedFiles as $fileName) {
echo "<li>".$fileName."</li>";
}
echo "</ul><br/>";
echo count($uploadedFiles)." file(s) have successfully uploaded.";
}                               
}

Форма html:

<form action="editGallery" method="post" enctype="multipart/form-data" name="formUploadFile">
<label for="files[]">Select image/images to upload:</label>
<input type="file" name="images[]" id="images" accept="image/*" multiple="multiple" 
placeholder="Upload an image/images.">
<input type="submit" name="uploadImages" value="UploadImages">
</form>

Сейчас сценарий выполняется и выдает ошибки после загрузки одного изображения в полноразмерный каталог и из того, что я предполагаю, он пытается создать большой палец и выдает ошибку.

В конечном итоге я не получил особой помощи или поддержки в этом опубликованном вопросе, но наконец-то получил его, и это был окончательный результат:

/** Create Thumbnails For Images Uploaded */
function createThumbnail($imagesName, $thumbWidth, $thumbHeight, $imagesDir, 
$thumbsDir) {
$imagesSource = $imagesDir."/".$imagesName;
$thumbImages = $thumbsDir."/".$imagesName;
list($width,$height) = getimagesize($imagesSource);
$thumb = imagecreatetruecolor($thumbWidth, $thumbHeight);
if(preg_match('/[.](jpg|jpeg)$/i', $imagesName)) {
$image_source = imagecreatefromjpeg($imagesSource);
} else if (preg_match('/[.](png)$/i', $imagesName)) {
$image_source = imagecreatefrompng($imagesSource);
} else {
$image_source = imagecreatefromjpeg($imagesSource); 
}
imagecopyresized($thumb, $image_source, 0, 0, 0, 0, $thumbWidth, $thumbHeight, $width, 
$height);
if(preg_match('/[.](jpg|jpeg)$/i', $imagesName)) {
imagejpeg($thumb,$thumbImages, 65);
} else if (preg_match('/[.](png)$/i', $imagesName)) {
imagepng($thumb, $thumbImages, 5);
} else {
imagejpeg($thumb, $thumbImages, 65);
