[SOLVED]How customers could upload their own ZIP files ?


Recommended Posts

Hi All !

I would like to propose my customers to upload their own ZIP files from the product customization fields in front office.
Pieces of solutions occurs in both french and english forums.
Is there someone who could explain step by step how to proceed for that ?
It would be appreciable to solve definitively this point : It would be nice to put [sOLVE] to this post.

Thanks a lot !

1. Go to your back office.
2. Create a new product and then there will be "Customization" tab
3. Enter number to "file fields".
4. Then click to "update settings"
5. After that you will see blank, there you can write upload detail.
6. Then click to "save" button.
7. Finally, go to your front office, click to product, there will see "Product customization" tab.

I hope it will be helpfull to you.

Hi again,

Someone told me : Help yourself and heaven will help you ! So, here is the solution :

1/ Modify product.php as below :

function isZIP($file)
{
   /* Detect mime content type */
   $mime_type = false;
   $types = array('multipart/x-zip','application/zip','application/x-zip-compressed','application/x-zip');

   if (function_exists('finfo_open'))
   {
       $finfo = finfo_open(FILEINFO_MIME);
       $mime_type = finfo_file($finfo, $file['tmp_name']);
       finfo_close($finfo);
   }
   elseif (function_exists('mime_content_type'))
       $mime_type = mime_content_type($file['tmp_name']);
   elseif (function_exists('exec'))
       $mime_type = trim(exec('file -b --mime-type '.escapeshellarg($file['tmp_name'])));
       if (empty($mime_type) || $mime_type == 'regular file')
               $mime_type = $file['type'];
       if (($pos = strpos($mime_type, ';')) !== false)
               $mime_type = substr($mime_type, 0, $pos);
   // is it a picture ?

   return $mime_type && in_array($mime_type, $types);
}

function pictureUpload(Product $product, Cart $cart)
{
   global $errors;

   if (!$fieldIds = $product->getCustomizationFieldIds())
       return false;
   $authorizedFileFields = array();
   foreach ($fieldIds AS $fieldId)
       if ($fieldId['type'] == _CUSTOMIZE_FILE_)
           $authorizedFileFields[intval($fieldId['id_customization_field'])] = 'file'.intval($fieldId['id_customization_field']);
   $indexes = array_flip($authorizedFileFields); 
   foreach ($_FILES AS $fieldName => $file)
       if (in_array($fieldName, $authorizedFileFields) AND isset($file['tmp_name']) AND !empty($file['tmp_name']))
       {
           $fileName = md5(uniqid(rand(), true));
           if (($error = checkImage($file, intval(Configuration::get('PS_PRODUCT_PICTURE_MAX_SIZE')))) && (!isZIP($file))) {
               $errors[] = $error;
               return false;
           }
           if (!$tmpName = tempnam(_PS_TMP_IMG_DIR_, 'PS') OR !move_uploaded_file($file['tmp_name'], $tmpName)) {
               return false;
           }

           if (isZIP($file)) {
                   $fileName = "P" . $fileName;
                   if (!copy($tmpName, _PS_PROD_PIC_DIR_.$fileName)) {
                                $errors[] = Tools::displayError('An error occurred during the file upload.');
                       return false;
                   }
                   $oldfile = './img/zip.jpg';
           } else {
                   $fileName = "J" . $fileName;
                   if (!imageResize($tmpName, _PS_PROD_PIC_DIR_.$fileName)) {
                                $errors[] = Tools::displayError('An error occurred during the image upload.');
                       return false;
                   }
                   $oldfile = $tmpName;
           }
           if (!imageResize($oldfile,  _PS_PROD_PIC_DIR_.$fileName.'_small', intval(Configuration::get('PS_PRODUCT_PICTURE_WIDTH')), intval(Configuration::get('PS_PRODUCT_PICTURE_HEIGHT')))) {
                        $errors[] = Tools::displayError('An error occurred during the image upload.');
               return false;
           }                    

                       if (!chmod(_PS_PROD_PIC_DIR_.$fileName, 0777) OR !chmod(_PS_PROD_PIC_DIR_.$fileName.'_small', 0777)) {
                               $errors[] = Tools::displayError('An error occurred during the image upload.');
               return false;
           }

           $cart->addPictureToProduct(intval($product->id), $indexes[$fieldName], $fileName);

           unlink($tmpName);
       }
   return true;
}



2/ Modify displayImage.php as follow :

<?php

$name = $_GET['name'];
$file = $_GET['img'];

require_once(dirname(__FILE__).'/../config/config.inc.php');
require_once(dirname(__FILE__).'/init.php');

$type = substr($file, 0, 1);
$img = substr($file, 1);

if ($img AND Validate::isMd5($img) AND $name AND Validate::isGenericName($name) AND file_exists(_PS_PROD_PIC_DIR_.$file))
{

   if ($type == "P") {
       header('Content-type: application/zip'); /*'multipart/x-zip','application/zip','application/x-zip-compressed','application/x-zip'*/
       $ext = ".zip";    
   } elseif ($type == "J") {
       header('Content-type: image/jpeg');
       $ext = ".jpg";
   }

   header('Content-Disposition: attachment; filename="'.$name.$ext.'"');
   echo file_get_contents(_PS_PROD_PIC_DIR_.$file);
}

?>



3/ Add ZIP icon (zip.jpg) into yourwebsite/img

Bye.
