Drupal 安裝pclzip module的步驟

1. 先安裝Libraries API  http://drupal.org/project/libraries 
2. 在Drupal中Enable Libraries Module
3. 安裝pclzip 模組時要去download兩個東西。一個是pclzip的核心程式 pclzip.lib.php（http://www.phpconcept.net/pclzip/pclzip-downloads）下載最新版本(目前是2.8.2版）
4.           另外一個是在Drupal用的module（http://drupal.org/project/pclzip）下載（pclzip-7.x-1.x-dev.tar.gz）
5. 在Drupal網站路徑 sites/all/下新建一個libraries資料夾。如果是多網站環境下就是在 sites/all/<domain>/下新建一個libraries資料夾
6. 在sites/all/libraries或是sites/all/<domain>/libraries資料夾內再建一個pclzip資料夾並把pclzip.lib.php放到此資料夾中。
7. 在drupal中安裝pclzip-7.x-1.x-dev.tar.gz這個pclzip模組
8. 修改pclzip.module file will be there in (pclzip module)
   Go to line# 79 - approx and replace the
   
   
   <?phpfunction pclzip_library_exists() {
  $pclzip_path = libraries_get_path('pclzip.lib.php');
  if (!is_file($pclzip_path)) {
    drupal_set_message(t('Could not find the PclZip library file : @pclzip_path', array('@pclzip_path' => $pclzip_path)), 'error');
    return FALSE;
  }
  return TRUE;
}?>
   WITH
   
   
   <?phpfunction pclzip_library_exists() {
  $pclzip_path = libraries_get_path('pclzip');
  $pclzip_path = $pclzip_path.'/pclzip.lib.php';
  if (!is_file($pclzip_path)) {
    drupal_set_message(t('Could not find the PclZip library file : @pclzip_path', array('@pclzip_path' => $pclzip_path)), 'error');
    return FALSE;
  }
  return TRUE;
}?>
9. 在Drupal中Enable pclzip模組
10. 一定要安裝Libraries API不然會出現miss libaries的錯誤。

補充作法：

Here if some one needs any help, you can use this as patch for now. I think the code that is written for now is wrong.

Do the following steps.

1- Download pclzip.lib.php

2- Create a folder named 'pclzip' inside your libraries folder (preferable - sites/all/libraries)

3- Copy pclzip.lib.php to sites/all/libraries/pclzip (folder) - the path might be diff you have created this folder else where

4- IMP and this is the patch.

Go to pclzip.module file will be there in (pclzip module)

Go to line# 79 - approx and replace the

<?phpfunction pclzip_library_exists() {
  $pclzip_path = libraries_get_path('pclzip.lib.php');
  if (!is_file($pclzip_path)) {
    drupal_set_message(t('Could not find the PclZip library file : @pclzip_path', array('@pclzip_path' => $pclzip_path)), 'error');
    return FALSE;
  }
  return TRUE;
}?>

WITH

<?phpfunction pclzip_library_exists() {
  $pclzip_path = libraries_get_path('pclzip');
  $pclzip_path = $pclzip_path.'/pclzip.lib.php';
  if (!is_file($pclzip_path)) {
    drupal_set_message(t('Could not find the PclZip library file : @pclzip_path', array('@pclzip_path' => $pclzip_path)), 'error');
    return FALSE;
  }
  return TRUE;
}
