input 类cookie的问题
本帖最后由 Closer 于 2015-7-16 13:52 编辑在默认配置里面，如果cookie_prefix为空的话，我们set_cookie之后，在cookie是没有问题的；但如果cookie_prefix有值的话，取出的值为空的？
按照官方的代码，在_fetch_from_array之前，不是得判断一下是否有前缀设置的情况吗？
下面官方代码：
/**
* Fetch an item from the COOKIE array
*
* @param mixed $index Index for item to be fetched from $_COOKIE
* @param bool $xss_clean Whether to apply XSS filtering
* @return mixed
*/
public function cookie($index = NULL, $xss_clean = NULL) {
return $this->_fetch_from_array($_COOKIE, $index, $xss_clean);
}
/**
* Set cookie
*
* Accepts an arbitrary number of parameters (up to 7) or an associative
* array in the first parameter containing all the values.
*
* @param string|mixed[] $name Cookie name or an array containing parameters
* @param string $value Cookie value
* @param int $expire Cookie expiration time in seconds
* @param string $domain Cookie domain (e.g.: '.yourdomain.com')
* @param string $path Cookie path (default: '/')
* @param string $prefix Cookie name prefix
* @param bool $secure Whether to only transfer cookies via SSL
* @param bool $httponly Whether to only makes the cookie accessible via HTTP (no javascript)
* @return void
*/
public function set_cookie($name, $value = '', $expire = '', $domain = '', $path = '/', $prefix = '', $secure = FALSE, $httponly = FALSE) {
if (is_array($name)){
// always leave 'name' in last place, as the loop will break otherwise, due to $$item
foreach (array('value', 'expire', 'domain', 'path', 'prefix', 'secure', 'httponly', 'name') as $item){
if (isset($name[$item])){
$$item = $name[$item];
}
}
}
if ($prefix === '' && config_item('cookie_prefix') !== ''){
$prefix = config_item('cookie_prefix');
}
if ($domain == '' && config_item('cookie_domain') != ''){
$domain = config_item('cookie_domain');
}
if ($path === '/' && config_item('cookie_path') !== '/'){
$path = config_item('cookie_path');
}
if ($secure === FALSE && config_item('cookie_secure') === TRUE){
$secure = config_item('cookie_secure');
}
if ($httponly === FALSE && config_item('cookie_httponly') !== FALSE){
$httponly = config_item('cookie_httponly');
}
if ( ! is_numeric($expire)){
$expire = time() - 86500;
}else{
$expire = ($expire > 0) ? time() + $expire : 0;
}
setcookie($prefix.$name, $value, $expire, $path, $domain, $secure, $httponly);
}
