Zend 框架：无法确定临时目录，请手动指定 cache_dir

Question

我只是在学习 Zend 框架。我创建了一个简单的 Zend_Form，当我提交表单时出现以下错误：

An error occurred
Application error
Exception information:

Message: Could not determine temp directory, please specify a cache_dir manually

Answer 1

我在它为我工作的主目录中创建了“tmp”文件夹

Answer 2

嗯，它说

"Please specify a cache_dir manually"

那就这样吧。

参考指南中的示例：

$frontendOptions = array(
   'lifetime' => 7200, // cache lifetime of 2 hours
   'automatic_serialization' => true
);

$backendOptions = array(
    'cache_dir' => '/path/to/cache' // Directory where to put the cache files
);

// getting a Zend_Cache_Core object
$cache = Zend_Cache::factory('Core',
                             'File',
                             $frontendOptions,
                             $backendOptions);

使用缓存资源插件时等效：

resources.cachemanager.database.frontend.name = Core
resources.cachemanager.database.frontend.customFrontendNaming = false
resources.cachemanager.database.frontend.options.lifetime = 7200
resources.cachemanager.database.frontend.options.automatic_serialization = true

resources.cachemanager.database.backend.name = File
resources.cachemanager.database.backend.customBackendNaming = false
resources.cachemanager.database.backend.options.cache_dir = "/path/to/cache"
resources.cachemanager.database.frontendBackendAutoload = false

Answer 3

我认为这解决了问题，它为我解决了问题

Zend_Date::setOptions(array('cache' => $cache)); // Active aussi pour Zend_Locale
Zend_Translate::setCache($cache);

在 bootstrap.php 中设置缓存后添加它

Answer 4

你可以输入.htaccess

SetEnv TEMP /tmp

Answer 5

我使用的是“memcached”而不是“文件”，所以我的问题有点不同。我通过使用解决了这个问题：

        $registry = Zend_Registry::getInstance ();
        $frontendOptions =
        array (
            'lifetime' => APPLICATION_ENV == 'development' ? '10' : '3600', 
            'automatic_serialization' => true
        );


    $backendOptions = array(
                        'servers' => array( array(
                            'host' => APPLICATION_ENV == 'development' ? '***' : '***', 
                            'port' => '***'
                        ) ),
                        'compression' => true
    );

    $cache = Zend_Cache::factory ( 'Core', 'Memcached', $frontendOptions, $backendOptions );

// Below is the fix for the problem! It appears that some validators / translates are caching
Zend_Locale::setCache($cache);
Zend_Translate::setCache($cache);

Answer 6

这样的事情应该会有所帮助：

$_SERVER['TEMP'] =  realpath(dirname(__FILE__) . '/tmp');

Answer 7

查看 Zend/Cache/Backend.php 代码时，有一些替代方法可以正确猜测 cache_dir：

• 设置环境变量，例如 TMPDIR、TEMP 或 TMP
• 在 php.ini 中设置“upload_tmp_dir”
• 允许访问“/tmp”或“\temp”

至少我是这样阅读代码的：

/**
 * Determine system TMP directory and detect if we have read access
 *
 * inspired from Zend_File_Transfer_Adapter_Abstract
 *
 * @return string
 * @throws Zend_Cache_Exception if unable to determine directory
 */
public function getTmpDir()
{
    $tmpdir = array();
    foreach (array($_ENV, $_SERVER) as $tab) {
        foreach (array('TMPDIR', 'TEMP', 'TMP', 'windir', 'SystemRoot') as $key) {
            if (isset($tab[$key])) {
                if (($key == 'windir') or ($key == 'SystemRoot')) {
                    $dir = realpath($tab[$key] . '\\temp');
                } else {
                    $dir = realpath($tab[$key]);
                }
                if ($this->_isGoodTmpDir($dir)) {
                    return $dir;
                }
            }
        }
    }
    $upload = ini_get('upload_tmp_dir');
    if ($upload) {
        $dir = realpath($upload);
        if ($this->_isGoodTmpDir($dir)) {
            return $dir;
        }
    }
    if (function_exists('sys_get_temp_dir')) {
        $dir = sys_get_temp_dir();
        if ($this->_isGoodTmpDir($dir)) {
            return $dir;
        }
    }
    // Attemp to detect by creating a temporary file
    $tempFile = tempnam(md5(uniqid(rand(), TRUE)), '');
    if ($tempFile) {
        $dir = realpath(dirname($tempFile));
        unlink($tempFile);
        if ($this->_isGoodTmpDir($dir)) {
            return $dir;
        }
    }
    if ($this->_isGoodTmpDir('/tmp')) {
        return '/tmp';
    }
    if ($this->_isGoodTmpDir('\\temp')) {
        return '\\temp';
    }
    Zend_Cache::throwException('Could not determine temp directory, please specify a cache_dir manually');
}

Answer 8

关闭/禁用缓存 :) 为什么在学习时将它用于简单的应用程序？还有更重要的东西要学；）
