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

Question

I am just learning Zend Framework. I created a simple Zend_Form and when I submitted the form I got following error:

An error occurred
Application error
Exce         


        

Answer 1

I have created "tmp" folder in the main directory it worked for me

Answer 2

When looking at the Zend/Cache/Backend.php code, there are some alternatives to allow correct guessing of the cache_dir:

• Setting evironment variables like TMPDIR, TEMP or TMP
• set "upload_tmp_dir" in php.ini
• allow access to "/tmp" or "\temp"

At least that's how I read the code:

/**
 * 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');
