Wie lade ich eine Thumbnail-Datei in einen Amazon S3-Bucket hoch?

Question

Hallo ich bin neu zu Amazon und habe sehr wenig Idee mit Dateien zu arbeiten. Ich versuche, ein Miniaturbild in den Bucket zu laden. Ich könnte ein Bild in localhost hochladen, aber ich konnte es in bucket.I nicht laden konnte das Originalbild zu dem heißen Stein lade, ist hier mein Code

<?php 
//include the S3 class 
      if (!class_exists('S3'))require_once('S3.php'); 

      //AWS access info 
      if (!defined('awsAccessKey')) define('awsAccessKey', ''); 
      if (!defined('awsSecretKey')) define('awsSecretKey', ''); 

      //instantiate the class 
      $s3 = new S3(awsAccessKey, awsSecretKey); 


function Upload($field_name = '', $target_folder = '', $file_name = '', $thumb = FALSE, $thumb_folder = '', $thumb_width = '', $thumb_height = ''){ 
    //folder path setup 
    $target_path = $target_folder; 
    $thumb_path = $thumb_folder; 

    //file name setup 
    $filename_err = explode(".",$_FILES[$field_name]['name']); 
    $filename_err_count = count($filename_err); 
    $file_ext = $filename_err[$filename_err_count-1]; 
    if($file_name != '') 
    { 
     $fileName = $file_name.'.'.$file_ext; 
    } 
    else 
    { 
     $fileName = $_FILES[$field_name]['name']; 
    } 

    //upload image path 
    $upload_image = $target_path.basename($fileName); 

    //upload image 
    if(move_uploaded_file($_FILES[$field_name]['tmp_name'],$upload_image)) 
    { 
     //thumbnail creation 
     if($thumb == TRUE) 
     { 
      $thumbnail = $thumb_path.$fileName; 
      list($width,$height) = getimagesize($upload_image); 
      $thumb_create = imagecreatetruecolor($thumb_width,$thumb_height); 
      switch($file_ext){ 
       case 'jpg': 
        $source = imagecreatefromjpeg($upload_image); 
        break; 
       case 'jpeg':

      } 
      imagecopyresized($thumb_create,$source,0,0,0,0,$thumb_width,$thumb_height,$width,$height); 
      switch($file_ext){

Probieren Sie diesen richtigen Pfad, wo Thumbnail in Ihrem Server root hochladen.

$upload_img = Upload('image','uploads/','',TRUE,'uploads/thumbs/','200','160'); 
    $upload_img1 = Upload('image','products/','',TRUE,'products/','200','160'); 
    // Absoulte path where to upload thumnail 
    //$fileTempName12 = $_FILES[$upload_img1]['tmp_name']; comment this line 
    //$fileName12 = 'products/'.$_FILES[$upload_img1]['name']; 
    //full path of the thumbnail image 
    $thumb_src = 'products/'.$upload_img1; 
    $s3->putBucket("bucketname", S3::ACL_PUBLIC_READ); 

    if ($s3->putObjectFile($upload_img1, "bucketname", $thumb_src, S3::ACL_PUBLIC_READ)) { 
     echo "<strong>We successfully uploaded your file.</strong>"; 
    }else{ 
     echo "<strong>Something went wrong while uploading your file... sorry.</strong>"; 
    }
